Extenders >> DVI Extender >> DVI RS232 ELR Extender (Discontinued)




Extra Long Range Extender for DVI, RS-232, and Ethernet over a single CAT-5e cable

This product has been discontinued and replaced by the:

Gefen DVI ELR Extender over One CAT5:
EXT-DVI-1CAT5-ELR (no Ethernet) or the Gefen 4K Ultra HD ELR-POL Extender: EXT-UHD-CAT5-ELRPOL
with CAB-DVI2HDMI-LCK cables.

The DVI RS232 ELR Extender extends any DVI source to a monitor, touch screen display, or other digital signage device 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-5e cable, allowing access and control of 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-5e 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. Use another RS-232 cable to 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.
