RS-232 SERIAL CONTROL
What features are available via the RS-232 serial communications port?
The 4x1 DVI KVM DL/SL 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 such as Putty*. The next few pages will
show you how.
What pins are used for communication with the 4x1 DVI KVM DL/SL
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.
