The GefenPRO Extender for HDMI ELR with PoL 2 over CAT5
The GefenPRO Extender for HDMI ELR PoL2 over CAT5 does everything that the
GefenPRO Extender for HDMI ELR with PoL 2 over CAT5 does, but adds active
source switching, with an additional Hi-Def input on the Receiver Unit. This pro-
vides the capability to switch between the Hi-Def source connected to the Sender
Unit and a local source connected to the Receiver Unit. The GefenPRO Extender
for HDMI ELR PoL 2 over CAT5 extends a Hi-Def source with multichannel digital
audio at resolutions of up to 1080p Full HD to 330 feet (100 meters), using one
CAT-5 cable. In addition, Gefen’s PoL* technology gives it the capability to power
an additional 5V DC device, up to 2 Amps, at the Receiver unit over the CAT-5
cable.
The Extender for HDMI ELR PoL 2 over CAT5 extends Ethernet and provides an
IR back channel to control A/V sources using the same CAT-5 cable extension.
With the built-in IR Blaster, simply point the IR remote(s) at the display to control
the Hi-Def sources as if they were located in the same room as the display.
How It Works
The GefenPRO Extender for HDMI ELR PoL 2 over CAT5 Sender unit is located
next to a set-top box or DVD player source. Use the supplied HMDI cable to con-
nect an HDMI source to the Sender unit. The GefenPRO Extender for HDMI ELR
PoL 2 over CAT5 Receiver unit is located up to 330 feet away, near the display.
Connect the HDTV display and another Hi-Def source to the Receiver Unit.
One CAT-5 cable connects the Sender and Receiver units to each other. The
Ethernet ports on both the Sender and Receiver units are connected to standard
network devices, such as 100Base-T routers and hubs. Multichannel digital audio
is embedded in the HDMI signal (Dolby® TrueHD / DTS-HD Master Audio™).
To use the switching capability, simply power on the Hi-Def source connected to
the Receiver Unit. The Extender will automatically switch to source connected to
the Receiver Unit. To revert to the source connected to the Sender Unit, simply
power down the source connected to the Receiver Unit.

12
DIP SWITCH CONFIGURATION
Receiver Unit
The GefenPRO Extender for HDMI ELR with PoL 2 over CAT5 contains DIP
switches on the bottom of the Receiver Unit. Each of these DIP switch performs
a different function.
See the next page for a description of the DIP switches.
Six DIP switches located on
the bottom of the Receiver
Unit.

13
DIP SWITCH CONFIGURATION
Receiver Unit
DIP Switch 1 - EDID Mode (Default = OFF)
• ON - Pass-Through Mode
DDC and HPD are passed through. Both the connection status and the full
video capabilities of the monitor are used by the source device.
• OFF - Local EDID Mode
Local EDID is used instead of the EDID from the display device. EDID
features newer than HDMI 1.3 are removed when the display is read. This
provides a general EDID which is compatible with more displays.
DIP Switch 2 - Hot Plug Detect (Default = OFF)*
• ON - HPD Pass-Through
HPD follows upstream HPD towards the source. The HPD signal will reflect
the connection status between the display device and the source device. If
the source or monitor is temporarily disconnected then reconnected, there
will be a delay of 20 - 30 seconds before the content is restored to the
monitor.
• OFF - HPD Always High
The HPD signal remains high regardless of the downstream HPD state.
If the source or monitor does not properly handle HPD (no picture after
connecting / reconnecting source or display), set this DIP switch to the OFF
position.
DIP Switch 3 - Supports DVI Connections (Default = ON)*
• ON - Disable HDCP
If a DVI connection is used, set DIP 3 to the ON position. DVI is supported
by disabling HDCP pass-through.
• OFF - Enable HDCP
If an HDMI device is connected, set DIP 3 in the OFF position.
*DIP switch is only operational when using Local EDID (DIP 1 = OFF).

14
DIP SWITCH CONFIGURATION
Receiver Unit
DIP Switch 4 - Green Mode (Default = OFF)
• OFF - Enable Green Mode
When DIP switch 1 on the Receiver Unit is set to the OFF position, the
Receiver Unit is placed in Green Mode. In this mode, the unit is not powered
unless +5V is detected on pin 18 of the HDMI cable. Green Mode consumes
less than 1 Watt of power.
• ON - Disable Green Mode
If DIP switch 1 is set to the ON position, then the Sender Unit is always
powered.
DIP Switch 5 - External Boot Loader Enable (Default = OFF)
• OFF - Disable
Setting DIP switch 1 to the OFF position disables the boot loader function.
• ON - Enable
Set DIP switch 1 to the ON position when using the bootloader to update
the firmware on the Receiver Unit. In this mode, the Receiver Unit will not
function as an Extender.

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. In some
cases, connecting through a patch might not work.

16
TROUBLESHOOTING
Cable recommendations
Solid core CAT-5e cable rated at 350 MHz and terminated in 568a or 568b is the
minimum requirement. For resolutions greater than 1280x1024 or 1080i, Gefen
recommends solid shielded CAT-6 cables.
No video
Make sure that DIP switch 2 on the Sender Unit is set to the OFF position. Also
make sure that DIP switch 5 on the Receiver Unit is set to the OFF position. If
either of these DIP switches are in the ON position (External Boot Loader Enable,
see page 10 and 14) then the Sender Unit or Receiver Unit will not function as an
extender. Next, make sure that the CAT-5 cable, connecting the Sender Unit and
Receiver Unit is connected to the LINK port. If this does not solve the issue, try
disconnecting and then reconnecting the AC power cord from the Sender Unit.
Also, verify that both units are working with short CAT-5e cables (15 - 20 feet).
Intermittent loss of video
Flickering or a blinking image is the result of a loss of sync between the display
and the source. Try lowering the source resolution (e.g. from 1080p to 720p). If
this solves the issue, then the CAT-5 cables being used to connect the Sender
Unit and the Receiver Unit are unable to handle the bandwidth of the higher
resolution and thus you are losing sync. Replace the existing CAT-5 cables with
a shielded CAT-6 cable. Electromagnetic Interference (EMI) from fluorescent
lights, generators, and A/C unit motors can also cause intermittent loss of video.
Shielded CAT-6 cable with the drain wire soldered to the connectors will resolve
the issue. Also make sure to eliminate any patch panels and wall plates. Patch
panels and wall plates are prone to EMI if they are not shielded properly.
Image is tinted green or pink
An image that is tinted green or pink is the result of the incorrect color space
being transmitted. Make sure that the display and source both support the same
color space. Setting DIP switch 1 on the Receiver Unit, to the OFF position, will
use the Local EDID. EDID features newer than HDMI 1.3 are removed when
the display is read. This provides a general EDID which is compatible with more
displays.

GLOSSARY
ADC
Apple Display Connector. TheADC interface is a proprietary interface developed
by Apple that combines analog and digital signals, USB, and power in a single
cable.
CAT-5
Category-5 cable, commonly known as Cat-5, is an unshielded twisted pair type
cable designed for high signal integrity. The actual standard defines specific
electrical properties of the wire, but it is most commonly known as being rated
for its Ethernet capability of 100 Mbit/s. Its specific standard designation is EIA/
TIA-568. Cat 5 cable typically has three twists per inch of each twisted pair of 24
gauge copper wires within the cable.
CAT-5e
Similar to Cat 5 cable, but is enhanced to support speeds of up to 1000 megabits
per second.
CRT
An acronym for Cathode Ray Tube: a common type of computer display
hardware.
DDC
Short form for Display Data Channel. It is a VESA standard for communication
between a monitor and a video adapter. Using DDC, a monitor can inform the
video card about its properties, such as maximum resolution and color depth.
The video card can then use this information to ensure that the user is presented
with valid options for configuring the display.
