Troubleshooting
3
Have you adjusted the Equalization setting on the repeater and/or
receiver units? There are built-in Equalization adjustment knobs on
every repeater and active receiver, which can be adjusted to obtain the
best picture quality. Use the mini screwdriver included with the product
to adjust this setting until an acceptable image is displayed. Note: An
improper Equalization setting can cause the monitor not to display an
image at all. Try each setting until an acceptable image is displayed.
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 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.
