The Gefen VGA RS232 Extender
The Gefen VGA RS232 extends any VGA source to a monitor or digital signage
application placed up to 330 feet (100 meters) using one CAT-5 cable. This
product also extends RS-232 using the same CAT-5 cable, allowing access to
control devices using RS-232.
How It Works
Place the Sender Unit next to the VGA source. Use the included VGA cable to
connect the source to the Sender Unit. Connect the Receiver Unit to the monitor
or digital signage display with a VGA cable (not supplied). Use one CAT-5 cable,
up to 330 feet (100 meters), to connect the Sender Unit to the Receiver Unit.
Connect an RS-232 serial cable from the RS-232 port on the Sender Unit to the
RS-232 control device. Connect the RS-232 port on the Receiver Unit to the RS-
232 device.
