RS-232 SERIAL CONTROL INTERFACE
What features are available via the RS-232 serial communications port?
The 8x1 DVI 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 memory bank and the EDID that is loaded into the
LOCAL EDID memory bank.
•
Upload new EDID data to the EDID memory 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 Windows
PC with the Hyperterminal program.
What pins are used for communication with the 8x1 DVI 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.
