OP8926 Pin Assignment
Page Content
Before designing cables, OPAL-RT recommends using these guidelines: Simulator EMC cable recommendations.
J1/J2 HDB44 Connector Pinout
As explained in OP8910 Hardware Interface, both HDB44 connectors J1 and J2 share the same pin-out.
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.

For more information about the use of Vuser and Vrtn pleaser refer to this article in the OPAL-RT knowledge base : How to power the different DB37 boards for digital outputs.
The direction of the signals D0 to D31 depend on the OP8926 assembly:
