TEHCM INTERFACE BOARD MANUALCHAPTER 1IntroductionThe Bauer TEHCM Interface Board (BTIB) is an external interfaceboard designed to provide proper control voltages and power to thetransmission electro hydraulic control module (TEHCM) device inorder to enable PCS to command and to receive data from theTEHCM.The BTIB performs the following supporting functions in conjunctionwith the National Instruments data acquisition and DIO boards used onPCS systems:• Translates square wave signals from speed sensors into analogvoltage signals.• Amplifies the power supply current for each TEHCM device undertest.• Optically isolates input and output signals to reduce disturbancesand prevent damage caused by electrical noise and ground loopiS.• Provides PWM-to-analog conversion for TEHCM solenoid drivercircuits.• Routes the CAN communication between ports on the TEHCM.This manual is written for machine builders and test engineers. It isassumed that those using this manual have a working understandingof electronic components and concepts and knowledge of the TEHCMconnected to the BTIB.November 13, 2008 Introduction / 1

TEHCM INTERFACE BOARD MANUALCHAPTER 2OverviewThe BTIB is used to interface the TEHCM to a test computer in a teststation environment. Each BTIB interfaces one TEHCM; when morethan one TEHCM is present in the test station, multiple BTIBs can bedaisy-chained in groups of one, two, or three. The total number ofBTIBs used at one station is limited only by the maximum current ofthe National Instruments PCI-6514 DIO Board, which can support over200 BTIBs at one test station.TEHCM Interface BoardThe BTIB contains the following connectors, jumpers, and LEDs:• P3—CAN interface to the test computer.• P5—The PRNDL signals that interface with the BTIB.• P6, P8, P10—Interface signals between the BTIB and the TEHCM.• P7—Connector used by all three CAN ports.• P9—Connector that connects the 12 VDC and V bat power supplies.The BTIB monitors the V bat current through this connector.November 13, 2008 Overview / 3

BAUER CONTROLS• P26—Ribbon cable connector that routes the analog output signalfrom the TEHCM to the data acquisition board in the test stationcomputer.• P40—Ribbon cable connector that routes all of the DIO signals.• Jumpers 1-9—Jumpers that determine the address of each of theboards on the daisy-chained ribbon cable.• Status LEDs—Green and red LEDs that indicate the status of thepower supply to the TEHCM.4 / Overview November 13, 2008

TEHCM INTERFACE BOARD MANUALCHAPTER 3Installation and ConfigurationUnpackingNOTE...Bauer Controlsrecommends that youwear a grounded wriststrap while unpackingand installing TEHCMInterface Boards.To prevent damage to the BTIB and its components, use the followingprocedure when unpacking your board:1. Verify that all required components have been shipped (see thetable in Appendix A).2. Discharge static electricity before removing the board from its antistaticwrap.3. Inspect the board carefully for damage. If any components aredamaged, return them to Bauer Controls for repair.RequiredHardwareThe following hardware components are required for installation(quantities vary depending on the project):• Bauer TEHCM Interface Board• 4-inch card guide• 26-pin analog ribbon cable• 40-pin digital ribbon cable• 40-pin interface board• 50-pin interface board• Single-Ended STB 100+ Board• DIO boardConfiguringThe BTIB is connected to the test station via jumpers and ribboncables instead of a chassis with a dedicated backplane. DIO signalsare routed on a 40-pin ribbon connector and the analog signals arerouted back to the PCS computer on a 26-pin ribbon connector. Thereare no analog output signals from PCS to the BTIB.One (1) 40-pin ribbon cable can connect up to three (3) TEHCMInterface Boards. Each digital signal from the test computer is routedto each BTIB through the 40-pin ribbon cable; therefore, one digitalsignal is common to all of the TEHCMs.November 13, 2008 Installation and Configuration / 5

BAUER CONTROLSHowever, digital signals sent from the TEHCMs to the BTIBs areunique to each TEHCM. DIO signals from each BTIB are individuallyrouted back to the PCS computer via the 40-pin ribbon cable. Jumperson the BTIB prevent a conflict between channels.NOTE...Jumper settings aredependent on the boardnumber, not the signalname.The 26-pin analog connector contains the same cluster of jumpers forup to three BTIBs.To set the jumpers on each cluster of BTIBs...1. Configure jumpers based on the following table:Board Jumpers Jumper Setting1 JP1 - JP9 A-B2 JP1 - JP9 A-C3 JP1 - JP9 A-DConnectingTo connect the TEHCM Interface Board…1. Insert each BTIB into a 4-inch card guide and secure it to theenclosure panel.2. Attach the 40-pin cable to each BTIB, as shown in the followingdiagrams.Single BTIB Configuration6 / Installation and Configuration November 13, 2008

TEHCM INTERFACE BOARD MANUALMultiple BTIB Configuration3. Attach the end of the 40-pin cable to the 40-pin interface board.4. Wire the 40-pin interface board to the 50-pin interface board basedon the DIO map listed in the project-specific application manual.5. Connect the 50-pin interface board to the DIO board in the testcomputer.6. Attach the 26-pin cable to the Single-Ended STB100+.7. Repeat steps 1-6 for each cluster of BTIBs you are installing.Shielding onthe BTIBThe 26-pin and 40-pin ribbon cables are shielded to reduce electricalnoise interference. To eliminate current loops, the shield is connectedto ground only at one end.The following twisted-pair shielded cables interface the TEHCM withthe BTIB:• CAN_1• CAN_2• CAN_Instrumentation• TISS• TOSSNovember 13, 2008 Installation and Configuration / 7

ETRS_PIC enables thePWM solenoid by sinking current with a 1 kOhm resistor. The signalturns on and off at a fixed frequency and the ratio of the on-to-off timeis the duty cycle.The PIC and PIE signals enable an optocoupler similar to theSOL1_RET and SOL4_RET optocouplers described in the previoussection. However, the output of the optocoupler is connected to an RCcircuit inside the BTIB that measures the pulse width ratio of the dutycycle. The output voltage of the RC circuit (analog signalSOL_PWM_n) is proportional to the duty cycle and has a span of 0 to 6volts.The ETRS_PIC carrier frequency that goes into the resistor capacitorelectronic circuit must be 10 Hz or higher for the circuit to functioncorrectly.NOTE...In the figure, “Ain”represents the analoginput signal to the PCScomputer.The following figure shows the connectors, pin assignments, andsignal paths for the PIE and PIC signals.10 / Signal Routing November 13, 2008

TEHCM INTERFACE BOARD MANUALTISS/TOSS/Hall SensorsThe TEHCM monitors the following signals from the BTIB:• TISS (transmission input speed sensor)• TOSS (transmission output speed sensor)• OUT OF PARK• PARK• PSWTPCS tests the TISS and TOSS circuits by driving the TEHCM with asquare wave using a PCI counter/timer board. DIN rail-mountedoptocouplers buffer the TISS and TOSS signals as they are routedfrom the test computer to the BTIB. An optocoupler on the BTIBsegregates any shorted signal from non-shorted TISS/TOSS signalson other boards. The output driver is an open collector sink circuit witha 680 Ohm pull-up resistor.The Out of Park, Park, and PSWT signals are typically static and theTEHCM measures the logic levels. The output driver for the OOP/PARK/PSWT circuits is an open collector driver with a 1.18 kOhm pullupresistor connected to V bat .NOTE...In the figure, “Dout”represents the digitaloutput signal from thetest computer.The following figure shows the connectors, pin assignments, andsignal paths for the TISS/TOSS/Hall Sensor signals.November 13, 2008 Signal Routing / 11

The BTIB incorporates a frequency-to-voltage converterthat measures the frequency of the replicated TOSS signal andtranslates the incoming frequency (up to 10 kHz) into a voltage rangingfrom 0 to 5 volts.The replicated TOSS signal sources current through a 2 kOhmresistor.The following figure shows the connectors, pin assignments, andsignal path for the replicated TOSS signal.12 / Signal Routing November 13, 2008

TEHCM INTERFACE BOARD MANUALPRNDLSignals (T92TEHCM Only)The PRNDL signals from the T92 TEHCM are logic states that selecttransmission operating modes, including Park, Reverse, Neutral,Drive, and Low. The BTIB electronic drivers sink current to the PRNDLsignals and include a 4.7 kOhm pull-up resistor on each signal.The ground (GND_IMS) from the T92 IMS connector is the return forthe PRNDL drivers. This circuit is current-limited through a 10 Ohmresistor. If the ground fails, all of the PRNDL inputs will also fail.The following figure shows the connectors, pin assignments, andsignal paths for the PRNDL signals.The PRNDL signals sink current through a 10 Ohm resistor and sourcecurrent through a 4.7 kOhm resistor.Ignition/Access/BrakeApply SignalsThe BTIB controls the ignition (IGN), access (ACCESS), and brakeapply (BRAKE_APPLY) outputs to the TEHCM. An optocoupleractivates the signals by sourcing current from the battery voltage. A100 Ohm resistor is added in series to current-limit the output if a shortcondition occurs.The following figure shows the connectors, pin assignments, andsignal paths for the ignition, access, and brake apply signals.November 13, 2008 Signal Routing / 13

BAUER CONTROLSThe ignition, access, and brake apply signals each source currentthrough a 100 Ohm resistor.CAN PortsNOTE...This test may interferewith communication ofthe CAN port. Performthe test when notcommunicating with theTEHCM via CAN.The TEHCM has two (2) independent CAN ports that are labeledPrimary and Instrumentation. Because the PCS computer only hasone port, a switching relay is incorporated on the BTIB to switchbetween the two TEHCM ports. The PCS output CAN_SELECTcontrols the relay and is common to all of the BTIBs.The CAN_H and CAN_L signals send CAN data from the testcomputer. Both the CAN_H and CAN_L signals are switched on andoff in pairs in less than 5 milliseconds.A third port (CAN_2) is redundant and hard-wired with the Primaryport. It is tested by measuring the internal 120 Ohm resistor that isshared between the Primary port and CAN_2.• If the resistor is connected, the detection circuit is enabled.• If the resistor is not connected, the circuit is not energized and thetest fails.The following figure shows the connectors, pin assignments, andsignal paths for the CAN port signals.14 / Signal Routing November 13, 2008

TEHCM INTERFACE BOARD MANUALTap Up/DownSignals (T92TEHCM Only)The tap up/down voltage is generated by combining up to four resistorsin parallel. Different voltages are sent to the TEHCM, depending onthe combination of resistors that are switched on. These voltagescommand the transmission states listed in the table below. The sourcevoltage V ps is the external variable power supply.The 8.3 kOhm resistor is permanently connected between V ps and theoutput; DIO signals add other resistors by controlling optocouplers.The BTIB tap up/down output is connected to a 400 Ohm resistorlocated inside the TEHCM. This resistor and the BTIB resistorstogether create the tap up/down voltage.When the 422 Ohm resistor is enabled, the output voltage exceeds the5 volts required to force the TEHCM into testing mode (as long as thepower supply is at least 12 volts). See Appendix B for moreinformation on the voltage settings for Manufacturing Mode.The following table describes the possible resistor combinations foreach transmission state. Included for each combination is the value ofthe resistors (Resistor Value), the DIO signals that enable the resistors(DIO Name), the commanded Transmission State, the resulting OutputVoltage, and the percentage of the source voltage that the outputvoltage represents (% of Power Supply).Resistor ValueDIO NameTransmissionStateOutputVoltage% ofPowerSupply8.3 kOhm N/A B 0.558 V 4.65%422 Ohm + 8.3 TAP1_EN I 6.0 V 50%kOhm4.34 kOhm + 8.3 TAP2_EN C 1.49 V 12.4%kOhm2.32 kOhm + 8.3kOhmTAP3_EN H 2.17 V 18.11%November 13, 2008 Signal Routing / 15

The electronic circuitconstantly monitors the current and disables the power to the TEHCMif an overload of 10 amps or more occurs for more than 20milliseconds.If an overload condition occurs, the MOSFET transistor turns off,disabling the power to the TEHCM. The monitoring circuit remainsdisabled until PCS turns the control signal (EN_PWR_n, located on theP40 connector) off and then back on.The LEDs on the BTIB indicate the power state:• Green LED—The TEHCM power is enabled.• Red LED—An overload is occurring and the TEHCM is connected.• Both LEDs on at half intensity—The TEHCM is not connected.A 0.03 Ohm resistor and a MOSFET transistor are in series with theadjustable power supply. An integrated circuit monitors the current ofthe 0.03 Ohm resistor.16 / Signal Routing November 13, 2008

TEHCM INTERFACE BOARD MANUALAn additional amplifier on the BTIB monitors the same voltage dropacross the same 0.03 Ohm resistor with a fixed gain of 50 volt/volt.Therefore:BATT_I_n = 1.5 * I TEHCMWhere n = the instance of the analog signal and I TEHCM = TEHCMcurrent.The following figure shows the connectors, pin assignments, andsignal paths for the power signals.November 13, 2008 Signal Routing / 17

BAUER CONTROLSLoopbackThe T90 TEHCM has redundant power and ground pins. The BTIBuses one set of power and ground pins to power the TEHCM devicewhile monitoring the second set of pins (VBAT_LOOPBACK andGND_LOOPBACK) on the TEHCM. The voltage divider shown in thefollowing diagram is used to monitor the two signals and the ground pinGND_ETRS (located on TEHCM connector J3-9).The T92 TEHCM does not use redundant power and ground pins. TheBTIB monitors the following signals on the T92 TEHCM:• V12B_TISS• V12B_TOSSIf any of the signals is faulty, the voltage LOOPBACK reflects thechange.The following figure shows the power and ground pins, V12B_TISSand V12B_TOSS signals, and the voltage divider.The following tables list the possible combinations of failure modeconditions of the loopback signals and the resulting loopback voltages(LOOPBACK_1) that reflect the failures.T90 TEHCMVBAT_LOOPBACKFailure Mode ConditionGND_LOOPBACK GND_ETRSOK OK OK 1.3 VFAULT OK OK 0 VOK FAULT OK 2.34 VOK OK FAULT 2.34 VLOOPBACK_118 / Signal Routing November 13, 2008
