Ultra Operating Notes
• Gefen recommends using CAT-5e (or better) cables.
• Resolution will affect extension distance. 1080p Full HD can be extended up to 495
feet (150 meters) and is limited to 8-bit color depth. 4K resolutions can be extended
up to 330 feet (100 meters). See HDBT (HDBaseT™) Mode (page 17) for details.
• Power Over Line (POL) is a Gefen proprietary technology that provides power to the
Receiver unit over a single CAT-5e (or better) cable. The included power supply can
be connected to either the Sender or Receiver unit. Never connect a power supply to
both the Sender and Receiver unit.
• This product passes through the display’s EDID to the source. If the display is capable
of accepting Deep Color, the source must be manually congured to output 8-bit color.
This is only applicable when using 4K x 2K resolutions and “long-run” modes.
See HDBT (HDBaseT™) Mode (page 17) for more information.

Updating the Firmware
There are two methods for updating the 4K Ultra HD ELR-POL Extender w/ RS-232,
Ethernet, and 2-way IR. The recommended method is to update both units at the same
time by leaving the Sender and Receiver unit connected. Updating the Sender unit will
update the Receiver unit (or vice versa). The second method is to update the Sender and
Appendix
Receiver unit separately.
Single Update Procedure
This method is recommended and can be used in situations where disconnecting the
system is impractical or difcult. The power supply must be connected to either the Sender
or Receiver unit. The update procedure can take place at the Sender or Receiver location.
1. Download the latest rmware here: http://www.gefen.com/support/download.jsp
2. Extract the contents of the .zip le to the desktop on your computer.
3. Disconnect the power supply from the Sender (or Receiver) unit.
4. Set the following DIP switches on the Sender and Receiver units:

Gefen recommends the TIA/EIA-568-B wiring option. Use the following table when
terminating cables in the eld.
Pin Color Description
1 Orange / White TD+ (Transmit Data, positive differential signal)
2 Orange TD- (Transmit Data, negative differential signal)
3 Green / White RD+ (Receive Data, positive differential signal)
4 Blue Unused
5 Blue / White Unused
6 Green RD- (Receive Data, negative differential signal)
7 Brown / White Unused
8 Brown / White Unused
Shielded (STP) CAT-5 or CAT-6 is recommended. However, unshielded (UTP)
CAT-5 or CAT-6 is acceptable. CAT-5, CAT-5e, and CAT-6 cabling comes in stranded
and solid core types. Gefen recommends using solid core cabling. CAT-6 cable is also
recommended.
It is recommended to use one continuous run from one end to the other. Patch cable is
not recommended.
