RS-232 SERIAL COMMUNICATION
What features are available via the RS-232 serial communications port?
The 8x1 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:
• Switching/routing of inputs to outputs without the RMT-8IR remote control.
• Switch EDID modes without operating the DIP switches on the underside of
the unit.
• Managing the EDID bank and EDID that is loaded into the LOCAL EDID.
• Upload new EDID’s to the EDID bank or directly to the LOCAL EDID
location.
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
with a terminal emulation program.
What pins are used for communication with the 8x1 DVI KVM DL/SL
Switcher?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.
