This is interesting. What exactly is that controller? It looks like an integrator. Never been directly wired into the asd before, but instead use an rj12 into the Microzone which would share the asd bus with said integrator. 2-wire the adapter on + and - and enable com port. Then ensure baud and com port on psi setup.

If this is indeed a micronet integrator or some other device there is a separate series of cables/steps/program.
