Pin | Signal | Description |
1 | nc | not connected |
2 | CAN_L | CAN_L bus line (dominant low) |
3 | CAN_GND | CAN ground |

| (connected on the cable shield) |
4 | nc | not connected |
5 | CAN_SHIELD | CAN ground |
|
| (connected on the cable shield) |
6 | POWER_GND | power supply input ground |
7 | CAN_H | CAN_H bus line (dominant |
|
| high) |
8 | nc | not connected |
9 | POWER_V+ | power supply input +7..32V |
The power input and the CAN lines are galvanic disconnect with a limit to ± 50V. There is an internal transzorb diode to limit the disconnect voltage.
If you don't need a galvanic disconnect, the pin 6 can be connected to pin 3 or 5.
The POWER_GND pin 6 is not connected with the CiA standard bus in every system. If the tool does not work, pin 6 could have to get connected to the power supply ground!
