1 DB37 Pin Assignments
2 DB9 Pin Assignments
3 CANbus Pin Assignments (Optional)

The following tables provide the general pin assignments for the OP4610XG’s DB37 and DB9 connectors.

Detailed pin assignments for all connectors can be found in the System Description document provided with your order, or refer to the pin assignment of the OP5300 series IO module associated with each DB37F connector.

Before designing cables, OPAL-RT recommends using the guideline Simulator EMC cable recommendations.
