Can the ASD driver of the I/A Series UNC or ENC be connected to the ASD bus actively operating under a GCM?

Issue

Can the ASD driver of the I/A Series UNC or ENC be connected to the ASD bus actively operating under a GCM?

Product Line

TAC I/A Series

Environment

I/A Series R2 and G3 ASD driver

Cause

Attempting to directly communicate to the ASD devices with two different systems simultaneously.

Resolution

The I/A Series UNC / ENC acts as the master of the ASD bus replacing the communications function of a GCM.  Do not connect the GCM's ASD bus with the UNC / ENC's ASD bus.  Connection of both devices to the same ASD bus will cause severe communications conflicts and improper bus operation.
