Before designing cables, OPAL-RT recommends using these guidelines: Simulator EMC cable recommendations.

J1/J2 HDB44 Connector Pinout

...

The 32 digital I/O signals are routed to both J1 and J2 connectors. This allows, for example, splitting the input and output signals into two different cables.
