Troubleshooting
4
What resolution are you trying to reach? Tripp Lite’s DVI over Cat5
extenders are tested to support up to 1920 x 1080 @ 60Hz video
resolution (See the Product Features section or the installation diagrams
in this manual for details on max distance and resolution when using the
repeater and the different receivers). The shorter the extension distance,
the higher the resolution you will be able to obtain. If you are not able
to get an acceptable image after adjusting the Equalization setting, try
lowering your computer’s video resolution and/or adjusting the refresh rate.
5
What type of cabling are you using? Inferior cabling can result in poor
performance, so it is important that you use cables that can support the
video resolution you are trying to obtain. To achieve maximum distance
and resolution, 24AWG solid wire UTP cable must be used. Tripp Lite’s
N202-Series Cat6 cables are made with 24AWG solid wire, as are the
N022-01K-GY (Cat5) and N222-01K-GY bulk cables. Also, the DVI
cables you are using must support the resolution you are trying to obtain.
Inexpensive, low quality DVI cables may not support the maximum
resolution. It is recommended that you use Tripp Lite’s P561-Series DVI-D
Single-Link cables, as they have been tested to work with the B140-Series
extender products.
6
Test your cables to ensure they are working properly. For example, connect
your DVI cables between a source and monitor that you know works to
see if the cable is functioning. For Cat5e/6 cable, connect it between a
computer and a network to verify that it establishes a network connection.
7
Do you have any patch panels or other devices in between the transmitter,
repeater, and receiver units? Tripp Lite’s DVI over Cat5 extender products
were designed to be connected directly from the transmitter to the
repeater and/or receiver via UTP cable. The more connection points that
are in between the source and the remote monitor, the more likely it will
be that signal degradation will occur, causing poor performance. If you
have a patch panel or other device in between, it should be removed from
the installation.
