Control/Status Ports
Control/Status A and B ports are female DB25 connectors used for General Purpose Input/Output (GPIO)
interactions between Converge/Converge Pro devices and external control devices such as wall switches and push-
to-talk microphones. Control programming enables external control devices and controller software to access the
Converge/Converge Pro serial command set, including common functions such as volume control, muting, room
combining, and running presets.
For more information on Control/Status Port A and B and other physical connections, see Controls and
Connections.
