The Gefen DVI RS232 Extender over CAT5 with Ethernet
The DVI RS232 Extender over CAT-5 with Ethernet extends any DVI source to
a monitor, touch screen display, or other digital signage application placed at a
distance up to 330 feet (100 meters) using one CAT-5 cable. This product also
extends Ethernet and RS-232 using the same CAT-5 cable extension, allowing
access to control devices using RS-232.
How It Works
Place the Sender Unit next to the DVI input source. Use the included DVI cable
to connect the source to the Sender Unit. Connect the Receiver Unit to the monitor or digital signage display with a DVI 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. Connect the Ethernet ports on both the Sender Unit and the
Receiver Unit to any computer source and extended Ethernet device.
