FREQUENTLY ASKED QUESTIONS
What kind of CAT-5e cable should I be using?
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, Xantech Corporation recommends
solid CAT-6 cables.
I’m getting no video on the screens, what can I check?
First thing to check is make sure that the video CAT5 is linked to the other video CAT5 port and the
same with the DDC ports. Try removing the power supply from the receiver side, if the power-light
turns off then you have your CAT-5 cables crossed. In some setups with grounding issues you will not
get a picture with the receiver powered. Test to make sure the units are working with short CAT-5e
cables 15-20 feet. You can also make sure you have the correct boost setting configured (refer to
page 5).
Occasionally the picture blanks out, how do I fix this?
Flickering or a blinking image is the result of a loss of sync between the display and the source. Try
lowering the resolution to see if that helps, if it does, the CAT-5 cables you are using are unable to
handle the bandwidth of the higher resolution and thus you are losing sync. Try a shielded CAT-6
cable on the video line to reduce interference.
You can also try adjusting the service switches. Usually this is caused by EMI and a shielded CAT-6
with metal RJ-45 connectors with the drain wire soldered to the connectors will resolve the issue.
Please refer to the service switch guide on page 5 for the different combinations.
Why is there a green or pink tint to my picture?
A tint of green or pink in the picture is a result of incorrect colorspace being transmitted. This can be
resolved by recycling power on your devices including the extender. If this does not help, the DDC
data containing the colorspace is not being transmitted correctly due to loss in the CAT5 cable, try
replacing the DDC cable.
