This new model, the GefenPRO ELR Extender for HDMI over Cat 5 with POL II, uses a traditional sender/receiver methodology to extend HDMI with 3DTV pass-through, IR, RS-232, Ethernet and power up to 330-feet (100m) in distance using just one Cat 5 cable.

Gefen POL technology is based on the PoE (Power over Ethernet) standard and frees the receiver from power requirements, while providing an additional 5V to power supplemental hardware, such as a switcher, splitter or scaler to further enhance system performance.

“This is an absolutely essential solution wherever power is limited in the display area,” says Gefen president and chief executive Hagai Gefen.

“Installers can now use just one Cat 5 cable to reach way beyond HDMI’s limits using Gefen’s ELR technology based on HDBaseT.”

The GefenPRO ELR Extender for HDMI over Cat 5 with POL II offers an optional receiver unit equipped with one additional HDMI input, so users can automatically switch between two HDMI sources, one connected to the sender, and the other connected to the receiver. Both sources can be alternately viewed at the remote location using auto switching, IR remote, local front panel selection or RS-232 control. When one source powers down, the receiver will automatically switch to the alternative source.

Both the IR backchannel and RS-232 connection on the receiver unit can be used to control the display from the remote location. This product is rack mountable and comes with a built-in internal power supply.
