RS-232 SERIAL CONTROL INTERFACE

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

The 8x1 DVI DL Switcher can accept commands through the RS-232 serial

communications port located on the rear panel. The current RS-232 control

features are the ability to switch/route inputs to outputs without the RMT-4IR

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 Windows

PC with a terminal emulation program. The next few pages will show you how.

What pins are used for communication with the 8x1 DVI DL Switcher?

Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.

A null-modem adapter should not be used with this Switcher.
