The connectors for probes and sensors are located on the front side of the instruments. 

A maximum of 15 instruments of the AK family can be connected in series. This configuration defines the 

maximum number of probes that can be connected, e.g. 15 units AK4t = 60 probes. 

A serial RS 422 interface enables the data of the connected probes to be retrieved by a computer. The 

corresponding connectors are located on the rear side of the instruments. 

i 

The operation of an RS 232 interface requires the use of converter "RS 232/422" (order number: 

2232422´). 

The first instrument in a system chain of multiple units of the AK series has to be connected to the power 

supply unit. The following instruments have to be interconnected via the W&S bus. The last unit in the system 

chain has to be connected to an RS 422 interface of the computer. If no RS 422 interface is available, 

the RS 232/422 converter will have to be interconnected.

Operation 

Communication via the Serial Bus Interface 

To enable the operation via an RS 232 interface, the RS232/422 converter (order number 2232422) 

has to be used! 

A set of useful and clear commands is used to control the instruments of the AK series. The master/slave 

principle is followed strictly, i.e. the instrument only responds to the commands sent by the computer. 

General Command Format 

The following command syntax is used to control the instruments of the AK series: 

[XBBAA........] 

[ - Identification to start command execution 

X - Channel 

BB - Command identification 

AA... - Arguments (if necessary) 

] - Identification to terminate command execution 

The command configuration for certain functions is shown in the list given in chapter 4. A command is 

immediately followed by a positive or negative response. In case of a positive response the character "!" 

is always in fourth place. In a negative response, the fourth character "?" is followed by an error code (see 

table of error codes in chapter 5). 

Commands either include a 4-digit argument or do not contain any argument at all. 

• 

• 

Command without argument, 

e.g. retrieve software version number: 

– Send [0VN] --> response [0VN!AK4-0834] 

Command with 4-digit argument (4 × ASCII HEX), 

e.g. set filter parameters of channels 1-4: 

– Send [0FP0100] --> response [0FP!] 

Operation with Multiple Instruments 

If multiple instruments are to be used, up to 15 units of the AK series can be controlled via a serial RS 422 

bus interface. In this case, every instrument has its own address (module number), which the manufacturer 

safely stores in the EEPROM. It can, however, be changed at any time. 

The string Contr.R AA only enables the instrument with the address "AA". "AA" represents a number in 

HEX-ASCII format, e.g. from 21 bis 2F on AK4... Therefore, the first instrument (module number 1) in a 

system chain that consists of 15 units has the address 2F. 

Contr.R = Chr$(18) = ^R = DC2 

Switchover of Instruments 

^RAA The instrument with address AA is enabled. 

The corresponding indicator LED on the front panel of the instrument is on. 

This command is not followed by a response. 

Switchover should only be made, if the current command has been answered completely.

Min/Max Measurement with Start/Stop Input 

To perform measurement with start/stop input, the corresponding PLC-connector has to be available on 

the instrument. 

Fig. 7 

Rear panel with PLC connector 

1 Input 

2 24 V (internal) 

3 Ground 

1 2 3 

The PLC output has to be connected to terminal 1 (Input). Terminal 3 (Ground) can be connected to PLC 

ground. 

For the duration of measurement, the signal on terminal 1 has to at HIGH (+24V). This time is used to determine 

the minimum and maximum values. 

After the signal changed to LOW (0V), the minimum and maximum values can be read out as often as 

desired.
