The OBD & INST Connector
The OBD & INST Connector is a Male 25-pin Standard D Type Connector with nuts.
Pin No | Pin Function |
Pin 1 | Analog Input 3- do not apply voltage outside of the -10 to +10 V range |
Pin 2 | LIN 1 |
Pin 3 | CAN / CAN FD Bus 3 Low signal |
Pin 4 | Analog Input 1 - do not apply voltages outside of the -10 to +10V range |
Pin 5 | Wake-Up pin to wake logger from sleep mode (for use, see Appendix 1) |
Pin 6 | CAN Bus 1 (Medium Speed Bus) Low Signal |
Pin 7 | CAN Bus 0 (High-Speed Bus) Low Signal |
Pin 8 | NC |
Pin 9 | 4.5-36V Supply Voltage |
Pin 10 | +4.5V Instrumentation Supply Voltage, ensure that the current drawn is not more than 100mA |
Pin 11 | Digital Input or Output 2 - Do not apply voltages outside of the 0 to +12V range when used as an input. When used as an Output, ensure that the current drawn is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3 |
Pin 12 | Digital Input or Output 0 - Do not apply voltages outside the 0 to +12V range when used as an input. When used as an Output, ensure that the current drawn is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3 |
Pin 13 | CAN /CAN FD Bus 2 (Instrumentation Bus) Low Signal |
Pin 14 | Analog Input 2 - - do not apply voltages outside of the -10 to +10V range |
Pin 15 | LIN 0 |
Pin 16 | CAN / CAN FD Bus 3 High signal |
Pin 17 | Analog Input 0 - - do not apply voltages outside of the -10 to +10V range |
Pin 18 | Analog Ground |
Pin 19 | CAN Bus 1 (Medium Speed Bus) High Signal |
Pin 20 | CAN Bus 0 (High-Speed Bus) High Signal |
Pin 21 | Ground - e.g. to be connected to pin 5 of the OBDII Connector |
Pin 22 | Power Ground - e.g. to be connected to pin 4 of the OBDII Connector |
Pin 23 | Digital Input or Output 3 (can also be used as a switched power supply +Vd). Do not apply voltages outside of the 0 to +12V range when used as an input. |
Pin 24 | Digital Input or Output 1 - Do not apply voltages outside of the 0 to +12V range when used as an input. When used as an Output, ensure that the current drawn is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3 |
Pin 25 | CAN / CAN FD Bus 2 (Instrumentation Bus) High Signal |
