The SymNet xControl serves a similar purpose for Edge and Radius as the Control I/O did for legacy SymNet SymLink and Express Cobra hardware. Its primary purpose is to bring the overall cost of logic I/O heavy systems down.
In conferencing applications the logic outputs are typically used to either light LEDs directly or interface with something expecting a control voltage that controls the LEDs itself. Typically, they are following mutes somewhere in the SymNet design which are linked to push-to-talk (push-to-unmute) logic.
External relays are often driven by logic outputs for the purpose of controlling a power sequencer or controlling a “conference in session” lamp/sign.
Logic outputs are sometimes use to interface with the GPIO inputs of a camera PTZ control unit which essentially expects contact closures to trigger it to preset camera positions. These may be driven in our system by presets, the Gating Automixer channel “ON” LEDs, or the PTT logic detailed above. Most often this type of setup is used during video conferencing or in court room applications.
The dual RS-232 ports on the xControl can be configured to send any custom RS-232 string in ASCII or Binary allowing SymNet to control 3rd party hardware. Often times a projector is used in a conference room or class room application, and must work in tandem with the audio system. Using an ARC remote or SymVue control screen as the user interface, when prompted by the host DSP the xControl can send
3rd party protocol commands to a projector, controlling common parameters such as On/Off and the selected input source.
