Installation/Operation 

1.0 Introduction 

1.1 General: The Echotrac MKII "all-in-one" Recorder/Digitizer/Transceiver utilizes the latest 

highly integrated digital and analog circuitry, display technology, and thermal printing 

techniques. Three 16 bit processors share real-time tasks of the unit and make the portable 

system an extremely capable and easily interfaced instrument. Exceptional system response is 

achieved by employing techniques such as digital signal processing, task sharing, asynchronous 

event processing, and multiple scan buffering. 

Dual Frequency Operation: Two frequencies are selectable from the following: Low (12kHz to 

50kHz), High (100kHz to 1MHz), Standard frequencies are 24kHz and 200kHz. 

Printer mechanism: The high resolution thinfilm thermal print head (216mm (8.5") wide, 8 

dots per mm (203/in.)) is capable of printing up to 16 gray shades. Because of its thinfilm 

construction, it consumes very little power when compared to previous technologies. 

Display: Film Super Twisted Nematic (FSTN) Dot Matrix LCD Module (320 x 200 pixels, 

0.38mm x 0.52mm dot pitch), Six inch (156.4mm) diagonal measure, on board controller and 

Fluorescent Back Lighting (CFL). The paper white display was chosen due to its excellent 

visibility in all light conditions from bright sun to darkened wheel house. 

Keypad: The 16 key Nema 12 sealed unit has full travel and tactile feel. The keypad is used by 

the operator for direct parameter entry and functional control of the unit from the front panel. 

Receive: The system incorporates both TVG and AGC. Sensitivity and AGC are continuously 

variable by front panel mounted potentiometers. Automatic gain control can be disabled by 

setting the front panel mounted potentiometer to the minimum detent position. The TVG curve 

is internally accessed. 

Transmit: Transmit frequencies are digitally synthesized and based on the stable frequency 

characteristics of a crystal controlled clock oscillator. Transmitted power for both high and low 

channels is individually adjustable via front panel mounted controls. Power is adjustable from 

the minimum of less than 20 watts in high frequency shallow water applications to over 1600 

watts in low frequency deep water versions. Transmit Pulse Width is variable either 

automatically (actual value dependent on frequency and depth) or manually by keypad entry.

2.0 INSTALLATION 

2.1 Echotrac DF 3200 MKII Recorder Installation: 

The Recorder is a free-standing unit designed for table top mounting. Rack or bulkhead 

mounting can be accommodated with the addition of special hardware. Where table top 

mounting is preferred, it is recommended that the unit be secured with external 'tie-downs' for 

rough seas or heavy swells. 

Power: Echotrac requires an input voltage of from +12 to +29 VDC (average power 

consumption approximately 75 watts) for proper operation. Most efficient operation is achieved 

at 24 VDC. Frequently, power is derived from two 12 V lead-acid batteries. Two "car" batteries 

(24V configuration), fully charged, and in good condition, can normally power a unit for a full 

day without re-charging. If an A.C. to D.C. converter is used, the output should be well 

regulated and monitored closely for voltage transients, spikes, etc. Regulated supplies should be 

able to source a short duration in-rush current spike of approximately 6 amps and an average 

current load of 3 amps. In the case of "charger" type (unregulated) supplies, the output should 

be "floated" across a battery load and not connected solely to the sounder input. Details of the 

power cable are given in Section 2.3. Should the input voltage polarity be applied in reverse, an 

audible alarm within the unit will sound regardless of the POWER switch setting. In the event 

that the input voltage drops below the minimum threshold the unit will automatically shut down. 

Fuses: Both the positive and return lines are protected by fast blow fuses. Two externally 

accessed fuses are mounted on the rear connector panel in units numbered higher than S/N 9450. 

In older units these fuses are mounted internally on the power distribution board. Both the 

positive and negative lines are fused at 7.5Amps. The negative fuse protects the unit from 

damage resulting from contact with external peripherals which do not share a common return 

path potential. 

Cabling: All cabling is via the connectors located in the recessed compartment at the top rear of 

the unit and arranged as shown in Figure 2.1. Cable details are given in Section 2.3. Care 

should be taken to route cables using horizontal and vertical runs wherever possible. Avoid 

paths that run adjacent to transmitter feeder cables or close to heat radiating elements such as 

steam pipes. For permanent installations, cables should be clamped at regular intervals (1m) 

along their complete lengths.

2.2 Transducer Installation 

Proper mounting of the transducer is a crucial part of the installation of any "survey" echo 

sounder. An improperly mounted transducer will result in poor system operation and 

unacceptable data quality. 

In the case of temporary installations, the transducer may be mounted over-the-side. In 

permanent installations and "pay surveys", hull mounts are generally preferred and often 

required. In either case, transducers should be mounted at least 0.3 meters below the waterline. 

In cases where "over-the-side" mounts are exposed to wave action, ensure that the transducer is 

mounted sufficiently deep so that it does not break the surface during vessel roll motions. 

A preferred mounting location is near the keel of the vessel, in an area where the planing 

attitude of the hull at speed, and the pitch and roll angles of the vessel in seas, have the least 

effect. The transducer should be mounted far enough aft of the bow so that bubbles generated by 

the bow wave will not pass over the face of the unit. Transducers should be located away from 

sources of turbulence and cavitation bubbles such as propellers, bow thrusters and hull 

protrusions. Considerations should also be given to sources of mechanical noise generated 

within the vessel (engines, props, pumps, generators, etc.). In some severe cases of mechanically 

coupled noise, vibration isolating mounts may be required to decouple the transducer from the 

hull. 

Transducer mounting can be accomplished in many different ways. To follow is a list of 

common configurations: 

2.2.1 "THROUGH HULL" Installation 

The top side of the transducer is accessible from inside the vessel while the transducer face is 

directly exposed to the water. Care should be taken to protect the transducer from damage and 

turbulence by installing a faring with a sloping forward edge ahead of the unit. The faring has 

the dual effect of both minimizing possible strike damage and smoothing the flow of water over 

the face of the transducer. 

2.2.2 "SEA CHEST" Installation 

In a "sea chest" mount, a fluid-filled enclosure, large enough to contain the entire transducer, is 

attached to the outer hull of the vessel. The outer hull is removed within the area of the chest 

and replaced with an acoustically clear "window", which is mounted flush with the hull 

surrounding the chest. Depending on construction, the material selected for the acoustic 

window, and the draft of the vessel, access can often be gained to the transducer from inside the 

hull without putting the vessel in dry-dock. In most installations, a water filled stand-pipe is 

incorporated into the "sea chest" design in order to provide hydrostatic pressure equalization. 

Transducer cables generally leave these assemblies through stuffing tubes which maintain the 

water-tight integrity of the chest.

DF 3200 MKII 


2.2.3 "OVER-THE-SIDE" Installation 

A temporary mount of this type is frequently constructed by welding a length of pipe to a plate 

which is drilled to accommodate the mounting points of the transducer. This fixture should be 

sized to position the transducer well below the waterline and the pipe then fixed to a sturdy 

support on the vessel. Lines generally are attached at the transducer plate and tied off fore and 

aft in order to maintain a stable, horizontal transducer attitude. Care should be taken to assure 

adequate protection for the transducer cable, particularly at the point where the cable leaves the 

transducer body. 

In all of the above installations particular care should be taken to assure that the transducers 

radiating face remains as nearly parallel to the water surface as possible while the vessel is 

underway.

2.4 Chart Paper 

2.4.1 General Paper Description 

The Echotrac MKII uses either thermal film or high quality thermal paper as the recording media 

for the analog chart. The rolls are 216mm (8.5") wide and contain approximately 52m (170') of 

paper (film rolls are approximately 30m long). The inside diameter of the core is 12.7mm (½"), 

and the outside diameter of the roll is about 64mm (2.5"). 

2.4.2 Loading paper 

Loading paper is a multi-step process, but it need not be a difficult one if care is taken to assure 

that each step is accomplished properly. As in almost all thermal recorders (including FAX 

machines), paper is sourced from a supply roll, where it passes between alignment posts, and 

over a roller, which moves the paper past the thermal printhead. A printhead release mechanism 

lifts the head away from the roller to assist in initial paper loading. 

In the Echotrac, printed chart paper is taken up on an empty core installed behind the paper 

access door at the far left of the chart panel. The motor which drives the take up spool does not 

advance the paper, as is the case in some echo sounders. Movement of paper across the 

printhead is accomplished by the precision stepper motor mounted atop the paper drive roller. In 

this configuration, previously printed chart can be pulled from the take up assembly for review 

and simply re-wound without disturbing the recording process. 

Loading Paper Procedures: 

1) Open and remove the chart door. The door is opened by pulling on the handle at the right 

side of the door, and is removed by lifting up on the left or hinged side. 

2) If paper has been previously installed in the unit, place the power switch in the 

STANDBY position and press the CHART FEED switch until sufficient paper has been 

advanced to clear any previously recorded data. Cut the paper at some point after the 

recorded data and press the Chart Take-up switch. This will allow the take-up 

mechanism to wind up the recorded chart. 

3) At the left hand side of the chart access cover, use your finger tips (positioned at the 

upper and lower ends of the paper entry slot) to pull the door outward releasing the 

magnetic catches mounted behind the door. Swing the panel outward and open to gain 

access to the paper supply and take-up assemblies. 

4) Locate the printhead release lever at the lower right corner of the printhead. Pull the 

lever out and to the left in order to lift the printhead away from the roller. 

5) Remove any remaining paper from the paper path and remove the spent supply roll from 

the holder mechanism by grasping the core and lifting upward and outward at the bottom. 


5/21/2003 10:57 AM 

2 - 6

DF 3200 MKII 


The upward motion compresses the upper pressure spring and the outward motion clears 

the bottom of the core from the lower core centering stud. 

6) Use the same motion in order to remove the take-up roll from it's holder mechanism. 

To Install a Fresh Paper Supply Roll: 

7) On the paper supply side (side closest to the printhead), raise the upper paper guide until 

the tension spring is fully compressed. 

8) Insert the fresh roll of paper (make sure that the paper comes off the roll on the right hand 

side) so that the core engages the top paper centering stud. 

9) Align the roll so that it engages the lower paper centering stud as the roll is set on to the 

lower paper guide. 

Feeding Paper Past the Printhead: 

10) Feed paper off the supply roll between the paper guide posts (located at the ends of the 

shaft mounted in front of the printer) and over the back side of the paper drive roller (the 

printhead release lever must be in the release position in order to accomplish this task). 

See the Paper Transport Diagram at the end of the section. 

11) Once a small amount of paper is fed through the printer and past the printhead, pull 

approximately 450mm (18") through the printer. This can be done easily if the paper is 

not allowed to engage the rubber paper drive roller with too much tension. Feeding paper 

manually off the supply roll while pulling it past the printhead will assist in this task. 

Once sufficient paper is fed past the printhead, center the paper on the paper drive roller 

manually and return the printhead release lever to the located position (head locked 

down on the paper drive roller). 

Loading the Paper Take-Up Spool: 

12) Guide the end of the paper through the hole in the paper access panel and pull all of the 

excess paper from the area between the access panel and the printer. 

13) Using a small piece of tape, attach the end of the paper to an empty paper core. Be sure 

to align the top and bottom edges of the paper with the core and wind 3 or 4 layers of 

paper up on it. Note: As shipped from the factory, paper is re-wound on the spent core 

in the same direction as it is fed off the paper supply roll. This means that the printed 

image is wound on the outside surface of the recorded roll. 


5/21/2003 10:57 AM 

2 - 7

DF 3200 MKII 


14) Employing the same method used in loading the supply roll, install the core (with paper 

attached) in the take-up drive assembly. 

15) Close the paper access panel. Press the CHART TAKE-UP switch and guide the excess 

paper through the gap in the end of the access panel and onto the take-up roller 

assembly. Holding a small amount of tension on the paper as it is being wound on the 

take-up core will help assure that the paper is aligned properly as recording proceeds. 

16) Press the CHART ADVANCE switch and observe that paper moves smoothly past the 

printhead across the paper access panel and is wound onto the take-up core. At this point, 

the recorded should be ready for normal operation.

4.2) which independently control the High and Low frequency channels of the unit. The Analog 

Controls are employed to adjust Transmit Power level, Receiver Sensitivity, Receiver Automatic 

Gain Control (AGC), and the Digitizer Threshold. 


5/21/2003 10:57 AM 

Fig 4.2 Analog Controls 

Note: The Transmit Pulse length for each frequency can also be adjusted using the parameter 

entry system. Refer to Section 4.2 for details. 

SENSITIVITY and AGC: The Sensitivity and AGC control knobs are located on concentric 

shafts of the same dual potentiometer. The Sensitivity control adjusts the amount of attenuation 

or amplification of the receiver, covering a range of approximately -20dB gain (20dB of 

attenuation) at the MIN position to +40dB gain at the MAX position. 

The AGC control determines the amount of variable gain applied to the preamplifier circuit. The 

AGC covers a range from 0dB (OFF) at the MIN position to approximately +20dB at the MAX 

position. 

4 - 4

DF 3200 MKII 


When activated, the AGC works on the principal of varying the gain of the preamplifier 

depending on the amount of signal present at the output of the receiver. Therefore, large signals 

on the output reduce the gain of the preamp, while a loss of signal (or small signals) returns the 

gain to the preset level of minimum AGC. 

TX POWER: The amount of transmit power to the transducer is set using the TX POWER 

control. This switch has 13 positions, AUTO and 1 - MAX (12). In the AUTO position, the 

Digitizer microprocessor automatically sets the TX POWER based on water depth. The 12 

manual positions cover the full range of the TX POWER in even increments. The 1 position is 

minimum and the MAX position is full transmit power. 

THRESHOLD: The THRESHOLD control determines at what amplitude the Digitizer will 

capture signals from the receiver output. The Digitizer ignores signals, which are lower in 

amplitude than the level set by the THRESHOLD control, while all signals exceeding the 

THRESHOLD level are captured and processed. 

The SET position of the THRESHOLD control (fully counter clockwise) sets the level at 

approximately 30% of full-scale amplitude. The level can be varied from 10% to 90% (MAX) of 

full scale amplitude by turning the control clockwise from the SET position. 

The SET position is recommended for most surveys. The variable settings can be used in special 

cases to: Raise the level above noise or other small signals to obtain a better lock on the bottom 

echo. To lower the level in order to digitize low level returns from bottom vegetation, etc. 

4.1.3 Chart Controls 

The CHART CONTROLS are located on the right-hand side of the Chart Panel and include the 

following: 

• MARK

• CHART TAKE-UP 

• CHART ON/OFF 

MARK: The MARK push-button switch prints an event mark on the chart record. 

CHART FEED: The CHART FEED push-button switch fast-advances blank paper from the

CHARTSCALE 

This parameter is toggled from AUTO to MANUAL by pressing the up-down arrow keys. These 

two values refer to the operating mode of the digitizer and its control of the center of the scale 

printed on the analog chart. In AUTO the digitizer is in an automatic scale change (auto 

phasing) mode. AUTO is selected when the operator wishes the Echotrac to automatically adjust 

the printed scale center so that bottom returns always remain visible on the chart. Should the 

digitized depth approach either scale limit, a new scale center is computed which will place the 

bottom (digitized depth) at a point 5/6th's of the way into the chart display area. This 'overlap' is 

necessary to prevent redundant scale changes in areas where the bottom varies near either edge 

of the chart. Auto Scale changes are noted on the chart by the printing of solid vertical black 

lines. In MANUAL the digitizer is constrained by the beginning and ending scale values 

regardless of depth. It is therefore quite possible in MANUAL mode to lose both digital and 

printed return data altogether, since the depth can easily change to the point where the bottom 

will be out of range of the manual scale limits. MANUAL is most often used to eliminate 

unwanted automatic scale changes which can occur in noisy conditions and where the limits of 

bottom depth changes are well known. 

FREQUENCY 

Select HIGH, LOW, or DUAL frequency operation using this parameter. In DUAL mode, 

operation is simultaneous, that is, both frequencies are transmitted at the same time. Please note 

that placing the unit in the DUAL mode does not automatically change the serial output to DBT 

(dual bottom tracking). Changing the output string requires selecting the new configuration in 

the AUX submenu. 

4 - 7

DF 3200 MKII 


CHARTCENTER 

The ChartCenter refers to the center value of the ChartWidth setting (the center of the printed 

chart). In the Manual CHARTSCALE mode, ChartCenter is used most often to move the scale 

limits to points that force the known depth to fall between the beginning and end of scale values. 

When the CHARTSCALE parameter is in AUTO mode, the ChartCenter value is recomputed 

each time the digitized depth approaches either scale limit. The ChartCenter interval is 

determined by ChartWidth/30 in UNITS = FEET or ChartWidth/7.5 in UNITS = METERS. 

CHARTWIDTH 

The ChartWidth parameter controls two closely related functions in the digitizing and recording 

process. First, ChartWidth sets up the limits between which return echoes can be plotted on the 

chart (ChartCenter - 1/2 ChartWidth and ChartCenter + 1/2 ChartWidth). Secondly, taken with 

CHARTCENTER it determines the end of scale value (ChartCenter + 1/2 ChartWidth), which is 

used to compute the approximate echo travel time to the deepest limit of the chart. Travel time 

sets the ping rate (see PingRate) of the unit. When the SCALE parameter is in Auto mode, the 

ChartWidth limits are recomputed to follow the new CHARTCENTER value but the actual 

ChartWidth value remains at the value selected. 

CHARTSPEED 

The thermal graphics printer is controlled by a dedicated microprocessor giving it independence 

from both the digitizer and front panel processors. When ChartSpeed is set to SYNC (zero), the 

printer is synchronized to the PINGRATE and prints one line of graphics (dot row) for every 

sounding cycle, thereby providing maximum sounding print density and resolution. Chart speeds 

do not correspond to survey speeds. 

CALDEPTH 

Sets the center of the digitizer's tracking gate or window to the depth entered. Once the expected 

depth of the bar is entered, the digitizer will only "see" the area defined by the gate limits 

(CalDepth ±0.5m). As an example: Lower the bar to a depth of 5 meters, select CalDepth and 

enter a value of 5m. Assuming the bar is within the ensonified cone of the transducer, the 

digitizer should lock on to the bar and ignore the return from the seabed. This parameter is used 

almost exclusively during bar check calibrations. 

VELOCITY 

This parameter sets the velocity of sound in water in feet or meters per second, as determined by 

the UNITS parameter. When modified, the new value is incorporated into the depth calculation 

formula immediately. The velocity of sound will be the same for both channels although the draft 

settings will most likely be different. See calibration procedures 'bar checks' (section 5.2). 

DRAFT 

Draft is the correction value added to the digitized depth (see fig 4.5 at end of section) to adjust 

for the difference between the actual depth of the transducer and the water's surface (a + d r ) 

where: "a" is the measured depth and "d r " equals the draft (depth of the transducer below the 

water surface "b", plus "k" or index constant). In the example below, "d" is equal to the depth of 


5/21/2003 10:57 AM 

4 - 8

DF 3200 MKII 


the seabed below the water's surface. In the dual frequency MKII, two DRAFT values are 

required in order to compensate for either separate transducer locations or differences in the "k" 

index constant. As one would imagine, DRAFTHI compensates for the high frequency 

transducer and DRAFTLO compensates for the low frequency transducer. Depth is computed 

according to the formula given in fig 4.5. Draft increments in hundreds of a meter or tenths of a 

foot. 

BLANKING 

Blanking is used to mask the transmit pulse, transducer ringing, or any other unwanted acoustic 

returns in the water column, from the digitizer. It is used when these returns could be mistaken 

as bottom echoes or when the operator needs to force the sounder to "see below" an interference 

layer . The value is entered as the distance from the water surface and is indicated on the chart 

as a solid black line printed at the selected depth. Changing this parameter causes a "Key" 

parameter printout unless the SW configuration parameter is set to 6 (see AUX menu). SW 

config. 6 also causes the blanking increment to increase to whole units instead of 1/10 ths . 

VIEW 

View determines the information to be plotted in the HYDROVIEWER display window. 

HFDATA or LFDATA displays the digitized depth data scaled to correspond with the chart. 

Comparisons made between the chart and the Hydroviewer can serve as a quick confirmation 

that the digitizer is locked to the bottom and transmitting the correct digital values. HFSGNL or 

LFSGNL plots a value corresponding to the relative signal strength of the echo return on a scale 

of 0 to 255. NOTE: All relative signal strength measurements should be made with AGC 

controls in the OFF position. OFF, selected as the value in the VIEW parameter, disables 

HYDROVIEWER updates. The View parameter also contains a Heave option. This allows 

watching the heave sensor settle without wasting 

paper.

SLOPE 

The average slope of the bottom is entered here in a relative value from 0 to 20, 0 being a flat 

bottom and 20 a rapidly changing bottom. This number is used to determine the amount of 

historical data to use in the calculation of the predicted tracking gate center. If too low a value is 

entered for rapidly changing depths, it is possible to lose bottom track frequently. Conversely, 

too high a value over flat bottoms may allow for near bottom features to be digitized. The slope 

actually opens up the tracking gate. ‘0’ is a narrow gate, while ‘20’ is a wide gate. It will not 

improve the resolution, but it can help the tracking. Also, the slope function can be used in 

conjunction with the PLOTGATE feature.

GAUGE 

The Gauge (or tide, river stage, etc.) can be entered here to offset the displayed depth. A line

PINGRATE 

This parameter refers to the pulse repetition rate of the sounder. The default is AUTO, that is, 

the sounder "pings" as rapidly as possible as dictated by the end of scale value, the velocity of 

sound and an amount of processor overhead time. Selection of a fixed number of soundings per 

second from a minimum of 1 / sec. up to a maximum of 21 /sec. is also possible. 

UNITS 

The operating measurement units of the sounder (feet or meters) can be changed at any time, 

with the POWER SWITCH in the STANDBY position. Once the new unit of measure is 

selected, all current parameters are recalculated and replaced. Please note this operation takes a 

few seconds to complete.

Table 4.2 

Table 4.2 indicates the resolution of the recorder at Range increments. The resolution figures in 

the above table are arrived at by dividing the minimum Chart width value by the number of dots 

across the printhead (1,500). It can be seen from the table that the operator's selection of a 

Rangevalue determines the ultimate resolution of the printed record. Digitizer resolution 

remains constant (at the values indicated above) throughout a single Range regardless of the 

ChartWidth selected. 

FILTERHI, FILTER LO 

An integrating filter circuit is provided which can improve acquisition of return data in many 

noisy conditions. This parameter toggles ON or OFF, either inserting or removing the filter 

circuit from the received signal path. Note: Care should be taken not to change the status of the 

FILTER parameter during the course of a survey after calibration has taken place. As with most 

analog filters enabling or disabling the filter may change signal path delays (index values). 

SKIPALARMS 

This parameter sets the number of soundings with no return, which will be ignored (i.e. the 

output depth will carry over from the last valid value). This is useful in some water conditions 

with much suspended sediment and as a general output data filter. The printed record will show 

a hollow alarm bar whenever a depth value is carried over. 

HFPWFilter, LFPWFilter 

The High and Low frequency pulse width filters were incorporated into the MKII code in order 

to enhance bottom digitization under conditions of high ambient noise. The purpose of the pulse 

width filter is to eliminate short duration returns from consideration by the digitizer as a possible 

bottom. 

We know that due to the propagation characteristics of the acoustic wave (the transmit pulse), 

that once the signal travels through the water column, is reflected from the seabed, and then

travels back to the receiver, that the echo at the receiver will be of longer duration (greater pulse 

width) than the originally transmitted signal. Based on this phenomenon we can then assume 

that echoes which are shorter than the transmit pulse are due either to noise or to minor reflectors 

suspended in the water column. 

In operation, the HFPWFilter and LFPWFilter reject returns, which are of shorter duration than 

an operator designated value. Default values for the two pulse width filters are based on the 

minimum values of the High and Low transmit pulses. Increasing the filter values causes the 

filters to reject echoes with wider and wider pulse widths. Conversely, decreasing the filter 

values allows more returns to be processed by the digitizer. 

Smoothing 

This parameter enables an averaging filter on the digitized bottom which has the effect of 

smoothing out the most recent depth output. The value entered is the number of depth values 

that is used in the averaging.

PRINTPARS 

With the unit in STANDBY, this feature initiates printing of all system parameter values on the

ANNOTATE 

When this parameter is turned ON, fix lines are annotated with the Fix Number, Date, Time, and 

Depth for both Hi and Lo Frequency Transducers. Special Conditions: When SW Config is set 

to 1, depth values are uncorrected for heave; 3, only the fix number is printed; and 4, the date is 

omitted. 

STARTNUMBER, INCREMENT, INTERVAL, COUNTDIR 

StartNumber, Increment, and Interval control the auto-marking feature of the sounder. The Start 

Number refers to the numeric value of the first mark line made on the chart. Each mark line 

thereafter is sequentially incremented or decrement by the Increment value. The interval in 

seconds between each mark is set by the Interval value. When Increment is set to zero, automarking 

is disabled. CountDir controls incrementing vs. decrementing of the mark number. 

FIXMARKSIZE 

Sets the width of Fix Mark lines on the printer (the higher the number, the wider the Fix Mark). 

Possible selections are 1 thru 10. 

PRINTLOGO 

Pressing the Enter key when this parameter is selected causes the Logo and Sign-on message to 

be printed on the chart. Note: Switch 1 on the Printer CPU card is used to control the printing of 

the Logo on switching the unit from STBY to ON. Setting this switch to ‘OPEN’ enables the 

feature (Logo printed at sign-on), and setting it off disables it (no Logo is printed). Selecting this 

feature is most often used for documenting a bar check without the necessity of cycling the unit 

through Stby. 

INTENSITY 

As the Intensity number increases to a maximum of 3, the darker the printing on the chart 

becomes. The darker chart printing is accomplished by increasing the Print Strobe time (or burn 

time). An unfortunate side effect of increasing the burn time is a slowing down of the sounding 

rate.

a motion compensator (either TSS or Seatex) are appended to the end of the serial string and 

depths are not corrected for heave. The fourth possible output is the DESO25 string. This string 

emulates the output of the Atlas echo sounder. NMEA 1 and NMEA 2 strings are also available.

POSITIONIN function to accommodate direct interfacing to the systems listed above. Possible 

baud rates are 300, 600, 1200, 2400, 4800, and 9600 baud. 

HEAVESENSOR 

This parameter identifies the heave sensor connected to the MKII. The default is NONE or no 

sensor connected. The 'TSSPRO' selection is standard for all TSS sensors including the 320B 

Processor/32X sensor combinations, the 33X series, and the latest model DMS-XX Sensors. 

'TSS-8' is a special high-speed protocol used when the TSS330 series sensor is setup in digital 

output mode 8. 'SEATEX' mode is for the Seatex MRUX motion sensors. See application 

notes at the end of this manual for more details. 

When activated, the raw heave and corrected depth are plotted on the chart in addition to the 

uncorrected bottom. The depth display is corrected for heave and in standard configuration; the 

serial output is also the heave corrected depth. Selection of HEAVE in the SERIALOUT 

parameter causes the output to transmit the raw depth and the raw heave, leaving the correction 

of depth data to post processing software. The heave lines are drawn on the printer and viewer 

only when there is heave data available.

Either connect the Serial Cable to the Com Port to be tested, and insert a paper clip in 

pins 2 and 3 of the DB9 connector, or insert a paper clip in pins 'A' and 'D' of the Com 

Port to be tested. 

With the MKII in STANDBY, initiate the diagnostic routine by selecting the port to be 

tested in the Diagnostics Menu, using the Arrow Keys. 

Hit the ENTER key. This causes the MKII to transmit alpha characters "A" through "Z" 

in uppercase, followed by the string '[¥]^_', then 'a' through 'z' in lower case followed 

by the string '[¥]^_’. The Loop back, achieved by placing the paper clip will route back 

all transmitted characters to the MKII, which displays received characters on the LCD 

screen, as shown in Fig 4.10. ASCII characters sent to the MKII by external devices 

such as GPS receivers or Motion Sensors can be displayed on the screen as well.

5.0 Operating procedures/Calibration 

5.1 Operating Procedures 

The following sequences are typical operating procedures for Echotrac MKII. The procedures 

may vary according to survey requirements and are intended only as a guide. It is assumed that 

the operator is familiar with the various controls and their associated functions as detailed in the 

preceding sections of this manual. 

5.1.1 Shallow Water Operation 

1. Insure that the unit has sufficient paper loaded for the survey task. Replenish if 

required (refer to section 2.4). 

2. Set the POWER switch to STBY and monitor that the unit prompts the operator to 

press the ENTER key twice. Note that the proper "sign-on" takes place. The sign-on 

message should include: customer or Odom logo, unit model number, and software 

version. 

3. Enter the parameters required for the survey task using the Keypad. Should any of 

the stored parameters seem out of range or the unit cannot be made to accept a valid 

parameter value, a DEFAULT RESET may be called for (Instructions for 

accomplishing a DEFAULT RESET follow in section 5.3). This procedure restores 

all parameter values to default norms (the values which are stored in system 

memory). 

4. Set the OUTPUT POWER switch to midrange, turn the THRESHOLD pot/switch to 

the SET position. Set the transmit pulsewidth to 1, adjust the SENSITIVITY controls 

to approximately midrange (this applies to both High and Low frequencies in dual 

mode), set the AGC control to minimum. 

5. Turn the POWER switch to ON. Insure that the key parameters velocity, incline, 

blanking, gauge, draft, time, plus unit of measure, and selected frequency are printed 

on the chart as the unit is turned from STBY to ON and that they are correct. Amend 

any of these parameters as required. Select the proper ChartSpeed as dictated by the 

requirements of the particular survey operation. 

6. If necessary, slowly adjust the SENSITIVITY controls until the desired chart quality 

is obtained and no digitizer alarms are displayed. Adjustment of the Tx Power 

control may be called for at this point. A balance between SENSITIVITY and Tx 

Power is generally desired. In many situations AUTO power will satisfy record 

quality requirements while at other times, where local bottom conditions dictate some 

variation of the Tx Power/SENSITIVITY ratio, a manual position may work best. 


5/21/2003 10:57 AM 

5- 1

DF 3200 MKII 


The AGC control will often help assure a clean analog record in the presence of noise. 

Note that the MAX setting on any of the above controls is seldom required. 

7. Should the record show evidence of sporadic noise that cannot be overcome using the 

Sensitivity or AGC controls, and should the digitizer lose lock due to this noise, then 

several alternatives are available. First, determine whether the digitizer is attempting 

to lock to a false echo or to the end of the Transmit Pulse. In either of these cases, 

enter a value for Blanking that is deeper than the false return. This will force the 

digitizer to lock to the bottom. Should this fail to help, then turn the Filter ON 

(found in the Digitizer menu). Lastly, turn the Threshold control out of the SET 

position, and adjust the level until the digital depths stabilize. 

8. If the Echotrac is connected to an external computer/data logger, confirm that correct 

digitized depths are being transferred. 

5.1.2 Deep Water Operation 

Please note that deep water operations require a bit more time to accomplish, due to the fact that 

returns from the bottom are received so much less frequently in deep water. For that reason, it is 

a good idea to set many of the standard parameters in STBY. 

1. In the SYSTEM menu select either the Auto or Manual scale change or Phasing 

mode (Chart Scale or Scale depending on SW version). 

2. Change the Frequency selected to LOW. Please note: The MKII will not sound 

deeper than 600 meters in either High Frequency or Dual Frequency modes (the High 

Range limit). 

3. Set the Chart Speed to SYNC. Setting the chart to advance one dot row per sounding 

will improve the appearance of the chart and eliminate the “blocky” appearance of 

records produced with low ping rates but high chart speeds. 

4. In the Digitizer menu, check that the SLOPE setting corresponds to the type of terrain 

likely to be encountered. Use a high number for rapidly changing bottoms and a low 

number for slowly changing bottoms. 

5. Set the RANGE value to encompass the greatest depth likely to be encountered. For 

example: if working in 2,000 meters of water, enter a RANGE value of at least 2,500. 

6. LFPulsWidth should be set to a value of at least 4. Used in conjunction with the 

front panel control, Tx Power, the pulse width and amplitude determine how much 

acoustic energy is actually transmitted toward the bottom. 

7. Turn FilterLow ON. The analog-integrating filter helps reject returns of a shorter 


5/21/2003 10:57 AM 

5- 2

DF 3200 MKII 


duration than the Transmit pulse. Since we know that in deep water the return will be 

reflected by a relatively large area of the bottom (due to beam spreading), then the 

receiver will see an echo which is 2 to 3 times longer than the actual transmit pulse. 

8. Back in the SYSTEM menu, set the ChartWidth value to suit the desired resolution. 

Remember, at a ChartWidth of 1500, each dot represents 1 meter. If you have 

chosen to work in the Manual ChartScale (Scale) mode, then set the ChartCenter 

value to the anticipated depth of the bottom. 

9. Turn Blanking On by entering a value. A Blanking value, which is a bit shallower 

than the “Shoalest” depth likely to be encountered, will help screen the digitizer from 

unwanted “false echoes” in the upper water column. 

10. In the View parameter, select LFData. This will result in the digitized value of the 

low frequency return being plotted in the Hydroviewer. 

11. Note: all of the above parameters have been set in STBY. Now turn the unit to the 

ON position and begin sounding. 

12. Begin by noting the position of the Tx Power switch. In most cases of depths over 

1,000 meters, the unit should be run at a fairly high power level (6 or greater). 

Slowly adjust the Sensitivity potentiometer to give the desired chart quality and to 

allow the digitizer to lock to the bottom. 

13. Both ACG and Threshold controls should be left in the detent positions unless 

conditions dictate their use. 

5.2 Calibration Procedures 

The principle of echo sounding is based on measuring the time of arrival of an acoustic return 

(echo) referenced to the time of transmission. The time required for sound to travel from a 

source (the transducer) to the seafloor or bottom, and back can be measured and multiplied by 

the velocity of sound in water in order to arrive at the distance the pulse has traveled. Since the 

transmitted pulse has traveled from the transducer to the bottom and back again, then the 

distance must be halved in order to obtain the water depth. As shown in the general depth 

formula below, other factors enter into the equation as well (see Fig 4.5 in section 4.2.1). 


5/21/2003 10:57 AM 

d = v • t +k +d r 

2 

Where: d - Depth from referenced water surface 

v - Average velocity of sound in the water column 

t - Measured elapsed time from transducer to bottom and back to 

the transducer 

k - System index constant 

d r - Distance from reference water surface to transducer (draft) 

5- 3

DF 3200 MKII 


Since depth measurement accuracy is dependent on the value used for the velocity of sound in 

water (along with the other factors shown above) it is important that a realistic value for sound 

velocity be determined. In water, velocity is a function of temperature, salinity and pressure. 

Understandably then, the local sound velocity may vary widely, thereby resulting in the need to 

calibrate any type of echo sounder, in order to provide the most accurate depth data at a given 

location. 

The most common calibration technique is the bar check method. This method, when employed 

properly, has the advantage of correcting for velocity variations, draft variations, and system 

index errors (all of the constants in the above formula). When calibrating using the bar check 

method, acoustic returns are generated by a suspended target, which is lowered to a known depth 

between the transducer and the bottom. In this circumstance it becomes desirable to have a 

method whereby the digitizer will see only the Bar (the target) and be prevented from locking on 

to the actual bottom returns. Since Echotrac employs a dynamic tracking gate or window 

through which the digitizer looks for echo’s from the seabed, manual control of the position and 

width of the gate is necessary in order to force it to remain fixed around the Bar. 

NOTE: Each frequency and transducer used should be calibrated independently and a separate 

"computed draft" determined for each. In actual practice, after velocity has been determined for 

one channel (usually the HIGH frequency), only the constant draft (inclusive of both d r and K) 

need be corrected in the second channel 

1. HEAVESENSOR must be set to none. 

2. With the unit in single frequency HIGH (for velocity calibration purposes), and 

adjusted to provide reliable depth information from the project depth and bottom 

material, set the SCALE parameter to manual. Set ChartCenter and ChartWidth to 

values which include the depths to which the BAR will be lowered. 

3. Deploy the BAR below the transducer to a depth of 5 meters or less. 

4. Select the system submenu and the CALDEPTH parameter. Adjust the CALDEPTH 

value until it agrees with the known depth of the BAR. 

5. Select DRAFTHI. Enter the difference between the observed depth (on the Echotrac 

display) of the BAR and the known depth of the BAR (determined from the BAR 

suspension chain). NOTE: This step corrects for both the DRAFT of the Transducer 

and the Index offset generated by the transducer and echo sounder electronics, and 

results in a "Computed Draft" figure. 

6. Lower the BAR to the deepest calibration depth. Select the CALDEPTH parameter 

and adjust it so that it equals the depth of the BAR. Note that the tracking gate reacquires 

lock on the BAR as soon as it comes within the limits of the ChartWidth 

value. 


5/21/2003 10:57 AM 

5- 4

DF 3200 MKII 


7. Select the VELOCITY parameter and slew the value up or down until the digitized 

depth on the Echotrac display agrees with the known depth of the BAR. This process 

should be repeated as many times as is required until readings at both levels are 

correct. IMPORTANT! Adjust DRAFT only when the BAR is at the shallowest 

depth and VELOCITY only when it is lowered to its greatest depth. 

8. Repeat the DRAFT calibration (steps 2 through 6) for the Low frequency 

(DRAFTLO). NOTE: Calibration should not be attempted in DUAL mode. 

5.3 DEFAULT RESET 

1. With the POWER switch in the OFF position, depress and hold the MARK switch. 

2. Rotate the POWER switch to STANDBY and note that the Graphic Display shows 

the following message: Restoring Status from EPROM 

3. Release the MARK switch. 

4. Press the ENTER (blue) key and observe that the second sign-on screen is displayed 

5. Press the ENTER key a second time and the display will switch to the SYSTEM 

parameter menu and the printer will "sign-on" with the proper messages including: 

Logo (if selected), model number, software version number, and serial number. The 

"sign-on" is followed by the "Key" parameter print out after the unit is switched to 

ON. 

6. Turning the POWER switch to the ON position initiates sounding. Please note that 

all menus and parameters are accessible in STBY. 

5.4 Side Scan Operating Procedures 

Deployment and operational recommendations: 

The Echotrac Side Scan Option utilizes the high-resolution gray scale thermal printer and the 

standard controls of the Echotrac MKII to produce quality side looking sonar images. An 

example of a Side Scan record follows. 

In this application, a 200 kHz, pole mounted, side scan transducer is simply connected in place 

of the standard “down-looking” transducer. The side scan beam is relatively wide in the across 

track direction (45° vertical) and narrow in the along track direction (0.7° horizontal). 

In order to present as shallow an angle as possible to the bottom and to avoid reflections from the 

water surface, the transducer should be mounted as deeply as possible (at least 1-2 meters below 


5/21/2003 10:57 AM 

5- 5

DF 3200 MKII 


the surface). It should be mounted rigidly and guyed both fore and aft in order to keep vibration 

from degrading the record. 

The mounting bracket allows for a range of depression angles of the transducer beam. The 

depression angle should be adjusted based on observations from the chart record. However, in 

general, it should be set so that the transducer is pointing slightly downward from the horizontal. 

This usually gives the best overall gain across the chart record. If the initial return from the 

bottom is very strong and the extreme range is very weak, the transducer is probably pointing 

down at too great an angle. Rotating the transducer up toward the water’s surface will improve 

the overall record quality.

Shades (if present) 16 

SENSITIVITY, POWER and HFPulsWidth settings should be adjusted so as to obtain the best 

printed record possible. The HFPulsWidth value should be set as short as possible in order to 

get the best resolution. However, the value may have to be increased to as much as 4 in order to 

find and initial starting point. Generally, the SENSITIVITY control will have the greatest effect 

on the recording. Do not be tempted to set the SENSITIVITY too high or data may be lost due 

to excessive blackening of the record at the near bottom. 

The ChartWidth (ScaleWidth) and ChartCenter (ScaleCenter) parameters should be set to suit 

the situation. ChartWidth (ScaleWidth) can be set at a value from 15m to 120m depending on 

the mission. An increase in ScaleCenter (ChartCenter) settings brings the initial bottom return 

closer to the top of the chart, thus eliminating much of the water column and getting more 

bottom data printed on the record.

6.0 Interfacing 

6.1 Computer Communications 

Due largely to the growing presence of Personal Computer based data acquisition systems 

aboard survey vessels; the need has arisen for echo sounders to communicate quickly and easily 

in a digital format. By far the most common communications interface is RS-232C. From the 

Comm 1 port, the MKII sends ASCII characters at 9600 baud, (8 data bits, 1 start bit, 1 stop bit, 

no parity) to peripherals or data logging systems at the completion of each sounding cycle. 

Comm 1 is a bi-directional serial port with the capability of accepting input data as well as 

outputting serial depth information. A description of protocol required for annotation and 

external control of function menu parameters follows later in paragraph 6.1.2. 

6.1.1 SERIAL OUTPUT STRINGS 

NOTE: This section applies when SW Config is set to 0, 2, or 3. A value of 5 adds a line feed at 

the end of the string. 

Single Bottom Tracking Output 

The following string is output when the unit is in either single frequency (either High or Low) or 

dual frequency (both High and Low) modes and Single Bottom Tracking is selected in the 

Auxiliary menu. When SBT is selected but the unit is operating in dual frequency, only the High 

frequency depth is output. This string has been maintained in order to assure downward 

compatibility with previous models. 

Note: Characters 2 & 3 indicate whether decimeter or centimeter resolution is selected (see 

example below). The foot serial output string varies from the metric string in that characters 2 & 

3 are always upper case.

to the Echotrac via the RS232 input line (ASCII Serial Input). Up to 80 ASCII characters per 

line can be accommodated. 

Event Line (Fix Mark) 

A single black line is printed across the chart by sending a HEX 06 (ASCII "ACK" or "Control 

F"). The event line or Fix Mark, is printed at the end of the current sounding cycle and does not 

delay or interfere with the normal operation of the unit. 

Event Annotation 

When required, the event line can be annotated with up to 80 characters of information. This is 

achieved by following the HEX 06 with HEX 01 (ASCII "SOH" or "Control A"). Depending on 

the status of SW1 (Front Panel CPU Software Configuration Switch), as in the earlier models of 

the Echotrac, the sounder will respond to the "Control A" with a HEX 02 (ASCII "STX" or 

"Control B"). Unlike the earlier "MKI" units, it is no longer necessary to wait for the "Control 

B" before sending annotation data. Data may be sent to the MKII immediately after transmission 

of the "Control A". The ability to either transmit "Control B" (for legacy customers) or to omit 

that function is controlled by SW1 on the Front Panel CPU card. Please see Table 4.3 

(SWConfig and Front Panel CPU Switch Programming). 

Annotation characters can be sent sequentially or with breaks between characters. The string of 

ASCII characters must be delimited by sending a HEX 04 (ASCII "EOT" or "Control D") to the 

MKII. Receipt of the ^D will cause the annotation characters to be printed and will return the 

ECHOTRAC to normal operation. 

** Note: Event annotation must contain at least one character before the HEX 04 delimiter 

even if it is only a HEX 20 ("space"). Care should be taken to avoid "annotation overrun". This 

phenomenon is caused by sending annotated events so often that they obscure the acoustic 

record. This most often occurs when fully annotated event marks are keyed to distance traveled 

along a survey line. This condition can be minimized by either limiting the number of event 

lines that get full annotation (limit annotation to depth and fix # on all event lines except the first 

and last) or by increasing the chart speed. 

Header Information (multiple line annotation): 

This type of information would normally be hand-written at the start or end of a survey line and 

would include information relating to date, time, work area, etc. Using the Heading Information 

input facility and the capabilities of your data acquisition computer, it is possible to have this 

information printed automatically on an otherwise blank section of chart. Each line is still 

limited to the maximum of 80 characters but there is no limit to the number of lines of 

annotation.

DF 3200 MKII 


Header information is sent in the same way as Event Annotation (see above) except that a HEX 

0D (ASCII "CR") delimits each line of information. The HEX 04 ("Control D") is transmitted 

only at the end of the complete header text. The following procedure steps through each phase 

of the Header Information input: 

1. Transmit HEX 01 (^A) to tell the sounder to expect annotation input. 

2. Transmit a line of header information to a maximum of 80 characters. 

3. Transmit HEX 0D ("CR") to print the line. 

4. Transmit next line of Header Information. 

5. Repeat step 3 and 4 as required until all Header Information is sent. 

6. After the last "CR", send the HEX 04 (^D) delimiter to return ECHOTRAC to 

normal operation. 

Note: In order to advance blank paper, send the HEX 0D ("CR") as many times as necessary. 

The communication / annotation facility can also be used to remotely stop or pause the chart. 

Use the HEX 14 (^T) command to stop the chart and HEX 12 (^R) to restart the chart. 

External Triggering: 

Individual sounding cycles may be initiated through the serial port. The external trigger mode 

may only be set via the serial input (cannot be accessed via the parameter menu). However, the 

external trigger mode is reflected by the parameter PingRate in the DIGITIZER menu. Once the 

unit is set to the external trigger mode, the PingRate parameter will be displayed as Extern. In 

this mode each sounding must be started by the "Ping" command (Control S) issued by an 

external device. The unit will remain in the external mode until that mode is changed via the 

serial input (a ^N is received) or power is removed from the unit. 

Use the following commands to enter the external trigger mode, to trigger a sounding cycle, and 

to terminate the external trigger mode: 

^E (Control E, HEX 5 ) Sets the unit to external trigger mode. 

^S (Control S, HEX 13) Triggers one sounding cycle 

^N (Control N, HEX E) Returns the unit to internal trigger mode. 

NOTE: Care should be taken not to issue the next trigger command until after the resulting 

depth output from the previous trigger command has been transmitted. This mode will override 

either the internal sounding rate or a computer selected PingRate (RepRate).

6.1.3 EXTERNAL CONTROL OF UNIT PARAMETERS 

Many of the parameters entered via the front panel keypad may also be entered via the serial port 

from an external computer or terminal. The external control feature allows remote input of the 

operating parameters from data files or through the computer keyboard. 

Some restrictions apply to external parameter inputs that, because of their absolute nature, are 

only tested against minimum and maximum limits. Front panel changes on the other hand are 

always processed in a controlled fashion in order to prevent possible system errors. Most often 

problems arise if the external parameter input is not in the correct multiple for the parameter 

addressed. For example, changing the ScaleWidth from 15 m to 60 m on the front panel is 

accomplished by pressing the UP button twice. With each actuation, the width is only allowed to 

change by a multiple of 15 and the proper multiple is always added or subtracted to the last 

value. If however, a ScaleWidth of 47.7 m is received on the serial input, the unit will process it 

and attempt to adjust all parameters accordingly. The result being system errors will follow. 

These may be so extensive that only a 'Power-Up Reset' procedure will recover the system. 

Protocol 

12 ASCII bytes maximum are necessary to complete a parameter transfer as shown below: 


5/21/2003 10:57 AM 

'Space'CR 

12 Characters Maximum 

Ex: '0' '8' 'SPACE' '1' '4' '6' '4' CR 

The sequence begins when ECHOTRAC receives a CONTROL P (ASCII DLE, HEX 10) 

followed immediately by the parameter control string (The parameter number (2 characters) 

followed by a SPACE (HEX 20) then the parameter value itself (which can be up to 8 characters 

long) followed by a carriage return). The transfer is then complete and the ECHOTRAC returns 

to normal operation using the new value. In the above example the VELOCITY identified by the 

parameter number 08 was changed to a new value of 1464 m/s. The string delimiter (CR) will 

always terminate the input. Use Control T (HEX 14) to stop the chart and Control R (HEX 12) 

to restart the chart. 

In order to provide continuity in interfacing to systems that were programmed for the older 

model ECHOTRAC, the MKII can be made to immediately respond to the CONTROL P with 

transmission of a CONTROL B (ASCII STX, HEX 02). See SWConfig 7 Table 4.3. 

As shown in Table 6.1, a unique number identifies each parameter. Table 6.1 is a consolidated 

table for reference purposes. It shows all the possible parameters each parameter's increment, 

multiplier, minimum and maximum values, and an example input code. Additional descriptions 

of parameters can be found in Section 4.2 of this manual.

7.0 Depth Simulator Board (93SIM) 

The Simulator board (93SIM) replaces the 93RX Receiver/Driver board in order to provide 

digital depth data from the sounder without the need of transducers. Existing front panel controls 

allow the operator to vary the depth plus the return signal amplitude and pulsewidth. The output 

of the simulator board is digitized and printed just as analog signals would be from a standard set 

of boards. 

7.1 Simulator Setup: 

Before installing the simulator board, check the setup to insure that the board will function 

correctly when installed. The default positions allow the simulator board to work without the 

need for any external components.

Appendix 1: Removal and Replacement of Software EPROMS 


5/21/2003 10:57 AM 

Fig A1-1 Showing EPROMS in Sockets U2, and U3, and Position of Pin 1 on the EEPROM. 

Removal and Replacement of Software EPROM’s 

Illustrated above is the Printer CPU board. It is typical of the 3 CPU boards found in the MKII 

(Printer, Digitizer, and Front Panel). Removal and replacement of System Memory (EPROM's) 

is common to all three boards. Please keep in mind that EPROM's are fragile electronic devices 

and as such must be protected from both physical and electrical damage. 

Several types of specially designed tools exist to aid in the removal and replacement of these 

devices. However, if care is taken, they can be successfully removed from their sockets with a 

flat bladed screwdriver, and reinstalled without the aid of tools at all. 

EPROM Removal 

1. Remove the CPU cards from the card rack by first lifting up on the ejector handle until the 

connector clears its mating socket and the corner of the board is free of the card retainer. 

Once the board is free of the connector and retainer, lift it straight up until it clears the top of 

the card rack. 

2. Place the board on a clean, static free work surface, circuit side down. 

Appendix 1- 1

DF 3200 MKII 


3. Locate EPROM’s U2 and U3 and identify pin 1 on each chip. 

4. Insert the blade of a small flat bladed screwdriver between the body of the IC and it's 

associated socket at the point directly under the indentation marking the pin 1 end of the 

chip. Do NOT use the PC board itself as a "prying point" for removal of the chip. To do so 

may damage the underlying multilayer circuits. 

5. Rotate the blade of the screwdriver until pins 1 and 28 begin to emerge from the socket. 

Insert the screwdriver further under the IC (to about the mid point) and repeat the process 

until all pins are completely out of their sockets. The objective is to remove the chip slowly 

and evenly so that the pins are not damaged in the process. 


5/21/2003 10:57 AM 

LEAD IN 

AREA 

Fig A1-2 Showing a 'cut out' view of the Chip Pin making contact with the Sockets Contact. 

EPROM Insertion 

As in step 2 above, the PC board should be placed on a clean, static free work surface, 

circuit side down. 

1. Note the position of Pin 1 on the EPROM and whether it is designated for position U2 or U3. 

With the "notched" or indented end of the IC facing upward, and the legs of the device 

pointing away from the viewer, Pin 1 will always be the top pin on the left row of pins. 

2. Carefully align one row of pins with its corresponding row of sockets. Line up the second 

pin row and confirm that all pins contact the lead-in area of the socket. Press the IC home 

using no more force than is necessary to assure the component is seated properly. 

3. Confirm that all leads are fully engaged and penetrate the socket contact area. Check that 

no pins have either been bent under the body of the IC or have otherwise failed to penetrate 

the socket.

4. After all EPROM’s have been replaced and confirmation has been made that all installed 

components are of the proper version # and installed in the correct CPU board, replace the 

boards n the card rack. Perform a DEFAULT RESET as described in Section 5.3 of the 

operators annual.

Appendix 2: Upgrading Software to "FLASH" memory 

The MK2COMM program is a utility to download new software into the Echotrac depth 

sounder. To use it: 

1. Connect your PC to the Echotrac's com1 using a standard 3 wire serial cable 

2. Switch on the power to the Echotrac and press the blue Enter key two times. 

3. Start the Flash program by typing "a:\mk2comm" at the computer keyboard. 

4. Choose option 1 to select your comm port. 

5. Select option 2 to download all processors. 

6. Specify the directory containing the ".bin" files which contain the new software. For 

example, type A:\ as the directory if the files are on diskette. 

7. Next, the program should connect to the Echotrac and begin the download. The time required 

will vary, but should not exceed 15 minutes. When the download is complete, cycle power on 

the Echotrac to start your new software.

be set to any parameter as these are ignored by the echosounder). 

• Set the MRU data update rate to 100 ms by moving the cursor to the bottom of page 3. 

• Set 'Auto Transmit' to 'Synchronous' and 'Interval (sync)' to 10 (i.e. 10 x 10 ms = 100 ms);

• Hit the carriage return key to exit the 'Edit' menu, and download the settings to the MRU. 

• The MRU is now configured for the Echotrac and the computer is no longer required. 

Connecting the MRU to the Echotrac will provide the corrected data on power-up. 

Vessel Installation: The best location for the MRU is near the Echotrac transducer, so that the 

actual transducer heave is measured. The MRU may be mounted in any orientation, but the most 

common orientation is with the connector pointing down and (looking at the engraving on the 

MRU end-plate) with the R-axis pointing to the vessel bow, and the P-axis pointing starboard. 

Echotrac MKII Setup: 

Select 'HeaveSensor' in the 'AUX' menu and set the value to 'SEATEX'. This will enable the 

Echotrac to use the SEATEX string.

Place the 320B in 'Profiler' mode, continuous output. 

NOTES: 

- When operating the MKII with heave enabled and at a PINGRATE greater than 15 per second, 

a noticeable latency occurs when changing any front panel parameter. This is due primarily to 

the processor overhead involved in reading the long heave data string (27 characters at a rate of 

approximately 20 per second). The digital output is not affected in any way however, and heave 

data remains synchronized to the ping rate. 

- The standard digital output string (SWConfig = 0) from a heave compensated MKII does not 

contain the "Raw" heave value. Both the "Raw" heave value and the uncorrected depth can be 

output by selecting SWConfig = 1 in the Aux menu.

begin printing the raw heave trace near the top of the chart and the heave corrected seabed just 

above the "uncorrected" or raw seabed. The depth displayed on the LCD panel is the Heave 

Corrected depth.

- When operating the MKII with heave enabled and at a PINGRATE greater than 15 per second, 

a noticeable latency occurs when changing any front panel parameter. This is due primarily to

Appendix 5 - 2

DF 3200 MKII 


the processor overhead involved in reading the long heave data string (27 characters at a rate of 

approximately 20 per second). The digital output is not effected in any way however, and heave 

data remains synchronized to the sounding rate. 

- The standard digital output string from a heave compensated MKII does not contain the "Raw" 

heave value. Both the "Raw" heave value and the uncorrected depth can be supplied as a custom 

string configured as required.

Appendix 6: Power Check 

The MKII can be powered by a +12 to +24 Volts DC supply with a minimum current rating of 

8.4 amps. Frequently, connecting two car batteries in series derives this power source. 

Sometimes, the connection scheme used is a source of failure, that doesn’t become apparent till 

other peripherals are interfaced to the MKII. Besides this, DC power circuits, within the MKII, 

could fail with age. In this section, we provide some basic power checking procedures that can 

be used to identify the source of the problem. 

Power Supply: 

Function: To provide: ±15, and -5 Vdc to power analog electronics; a +5 Vdc logic supply, 

and +50 Vdc used to drive the transducer. 

Equipment Required: Voltmeter. 

Procedure: 

With the MKII disconnected, from the external power source, measure and verify 

supply voltage to be approximately 12 - 24 V DC. 

Remove the chart panel, and check Fuses F1, and F2 on the cable harness, for 

continuity (newer units have their Fuses located on the Back Panel). Blown fuses 

should be replaced, and power supply modules checked for any shorts to ground 

before powering up the Unit. 

Blown fuse F2, is an indication of power supply grounding problem. Check all 

connections to the MKII: power supply, external equipment such as Personal 

Computer, Heave Sensor GPS, etc.

Appendix 6 - 1

DF 3200 MKII 


We now give an example of an incorrect, grounding scheme, found to cause fuse F2 to blow, 

followed by a correct grounding scheme. 

Referring to fig A6-1, in order to obtain the 24 Volts DC, needed by the MKII, power is derived 

by connecting two 12 Volt car batteries in series. However, the 12 Volts needed to power the PC 

is derived by connecting the PC to battery 'A', this configuration causes the PC ground to be 12 

Volts above the MKII ground. It is not until the PC to MKII connection is made by an RS232 

cable, that the problem surfaces (blown fuses). This grounding problem can occur with any 

external device connected to the Sounder, in this way.

The problem is corrected by powering the PC from battery 'B'. In which case, both the PC and 

the MKII will have the same ground (fig A6-2). In short, all peripherals connected to the MKII 

should be powered with a ground common to the sounder.

Once the Supply Voltage, and grounding are verified, insert the meter ground probe in pin 8 of 

any one of the Green Connectors, connecting the power modules to the power distribution 

motherboard. Make all measurements in the corresponding hole located on the green connectors 

labeled J2 through J5. 

Measure and verify +15 V DC at Pin 6 of J2 (Analog Supply). 

Measure and verify -15 V DC at Pin 7 of J2 (Analog Supply). 

Measure and verify + 5 V DC at Pin 5 of J2 (Logic Supply) 

Measure and verify approximately 24 - 26 V DC at Pin 6 of J3 (Print Head Voltage).

Measure and verify + 5 V DC on the far right leg (pin 3), of VR2 on the power 

supply distribution board. This is best accomplished by loosening the four quarter 

turns holding the card rack, then lifting the card rack up and sliding it forward, thus 

exposing VR2, and VR3 for easier access. 

Measure and verify + 5 Vdc on the far right leg (pin 3), of VR3 on the power supply

MiniScan Digitizer SubMenu 

Below is a graphical layout of the Digitizer SubMenu. 

DELAY 

The delay parameter controls the amount of delay in milliseconds the digitizer waits before firing 

the next transducer (start of next channel sounding cycle). The default is AUTO which is the 

minimum delay based on the current end of scale value (45ms), the delay is selectable from 

50ms to 1s but will be ignored if sounding range is longer than the allotted delay. 

GAIN 

The Gain can be adjusted for each channel individually by selecting the channel using the 

left/right arrows then slewing the gain value using the up/down arrows. This is a relative gain 

applied to the Sensitivity Control (section 4.1) gain, which acts as a master to the entire amplifier 

array.
