OP8120 Gen 2 DB37 Pin Assignments

When mounted in the OP8120-2 chassis, each module’s channels correspond to a specific pair of pins of the P1 or P2 DB37 connectors at the rear (center and right photos) and a pair of pins on the DB37 of the real-time simulator.

Each OP8120 module installed in one slot of the chassis represents a block of 4 analog channels on the simulator.

The simulator connector pin assignments and the OP8120 connector pin assignments are given in the table below.
For the purpose of this table, each slot, from left to right, is numbered from 1 to 8 as shown below (left photo).
