I/O A and B Connectors

The "A" connector has four digital, optically-isolated outputs and three differential analog inputs.

The "B" connector has four digital, optically-isolated inputs and three differential analog inputs.

Digital input common and digital output common are on the Auxiliary I/O connector (refer to Auxiliary I/O Connector).
