RS-232 Serial Control Interface

What features are available via the RS-232 serial communications port?

The TV Multi Format Switcher can accept commands through the RS-232 serial communications port located on the rear panel. The current RS-232 control commands allow switching/routing of A/V inputs to outputs without the use of the IR remote control.

How do I use these features?

These features were initially intended for utilization by custom installers in automated setups. However, these features can be tested by using any computer equipped with a 9-pin serial port and a terminal emulation program.

What pins are used to communicate with the TV Multi Function Switcher?

Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication. A straight-through cable should be used with this Switcher.
