Default Pin Assignments

For default pin assignments for Control/Status ports by model, refer to Appendix B.

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.

Control/Status Pin Programming

Use the following procedure to program user-definable pins:

1.

In the Control/Status Pin Select section of the screen, select port A or B from the Control Port drop-down
list.

2.

Select the pin you want to configure from the Selected Pin drop-down list. (Pin 1 is selected by default for
Control Port A and Pin 21 is selected by default for Control Port B.)
