Control Tab

The Control Tab allows you to configure pin assignments for the user-definable pins on Control/Status Port A and Control/Status Port B.

All models implement control/status using DB-25 pin ports on the back panel, and GPIO (General Purpose Input Output) with active low/pull to ground inputs and open collector outputs. For details, refer to Appendix B and the Control/Status Ports section of Appendix D: Specifications.

The control ports enable external devices to access the Converge/Converge Pro serial command set, including common functions such as volume control, muting, room combining, and preset changes. All devices connected via the E-bus can be controlled from a single control/status port on any of the devices.

Accessing the Control Tab

To access command control, press the Control Tab on the Tab Bar in Console.

The Control tab of the Console main screen shows a graphical representation of Control/Status Port A. The pins numbered in blue are user-definable command pins; the pins numbered in green are status pins. Control interface functionality and pin programming are explained in the following sections.

User-Definable Pins

The user-definable pins provide control via contact closure, and status via open collector functions in the unit. There are two user-definable pins on the B port of every unit. The number of user-definable pins on the A port varies by model, as summarized in the following table:
