Arduino VISCA Controller

The project is a work-in-progress

This is a project for using an Arduino to send VISCA commands. This is tailored for interfacing with the Cisco TelePresence PrecisionHD series of conference cameras (specifically testing with the TTC8-02 12x zoom w/ SDI output).

The TelePresence cameras have a slight quirk to controlling it over VISCA. To get manual control over the pan/tilt/zoom rates the camera needs to be sent the IR disable command, otherwise all movements behave with a speed ramp as if you were controlling it with an IR remote.

The Arduino Shield board present in the EAGLE directory is intended to make connecting to a TelePresence camera and wiring I/O easier. The shield has headers to allow for powering the Arduino off its internal voltage regulator or via VIN (includes header points to make swapping easy). There is also a header to provide 12v power over the RJ45 connection to remotely power the camera. The shield incudes an RS232 transciever so it is ready to plug into the camera's control port with a standard ethernet cable.
