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.
