The optional CAN bus card features two separate CAN buses connected together via a
9-pin Sub-D connector.
The connector on the power supply line assembled by the customer must have the following pin
assignment:
Pin Signal

2 CAN1-L
3 CAN1-GND
4 CAN2-L

Each CAN bus must be terminated at both ends with a 120 Ω terminating resistor.
If the OPC9000 is on one bus end, the corresponding resistors must be integrated in
the customer's connector.
