DIP SWITCH CONFIGURATION
Receiver Unit
The Gefen DVIKVM Extra Long Range Extender Over One CAT5 contains DIP
switches on the bottom of the Receiver Unit (the Sender Unit does not contain
any DIP switches). Each DIP switch performs a different function.
DIP Switch 1 - EDID Management
• OFF - Local EDID
When Local EDID mode is used, the EDID will be assembled by copying all
video and audio features of the connected output device.
• ON (default) - Pass Through EDID
Allows all video and audio features of the connected devices to be passed
to the source device. By default, the unit is shipped with DIP 1 in the ON
position.
Two DIP switches located on
the bottom of the Receiver
Unit.

10
DIP SWITCH CONFIGURATION
DIP Switch 2* - DVI Support
• OFF
If an HDMI source is connected, set DIP switch 2 to the OFF position.
• ON (default)
For DVI connections, set DIP switch 2 to the ON position. DVI is supported
by disabling HDCP pass-through.
*DIP switch is only functional when DIP switch 1 is set to the OFF position.
Once DIP switch changes have been made, the unit must be power-
cycled for the changes to take effect.

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 the source is not a dual-link source (resolutions greater than
1920 x 1200). If using a DVI, the source signal must not be HDCP-encrypted.
Make sure that DIP switch 2 on the Receiver Unit is set to the ON position. The
DVIKVM Extra Long Range Extender Over One CAT5 will only pass HDCP
content when using HDMI sources. If this does not resolve the issue, then
make sure that the display (sink) is compatible with the source. Ensure that
the resolution and timing of the source device can be used with the display (or
other sink) connected to the Receiver Unit. Next, make sure that the Cat-5
cable, connecting the Sender Unit and Receiver Unit is firmly connected to the
LINK ports on both units. If this does not solve the issue, try disconnecting and
then reconnecting the power from both the Sender Unit and the Receiver Unit.
Make sure that both units work with shorter Cat-5e cables (15 - 20 feet) before
extending to greater distances.
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.
