Troubleshooting
If you are unable to get an acceptable image after following the
installation instructions, try the following troubleshooting tips:
1
Are the external power supplies that came with the product
connected and plugged into a working power source?
For the
product to function properly, it must be connected to and receiving
power from the external power supply.
2
Was the power to the connected devices turned off prior to
installation?
If not, restart them.
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 HDMI over Cat5
extenders are tested to support up to 1080p @ 60Hz video resolution.
See the
Product Features
section or the installation diagrams in this
manual for details on maximum 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 and it is important to use cables that 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.
The HDMI cables you are using must also support the video resolution
you are trying to obtain. Inexpensive, low quality HDMI cables may
not support the maximum resolution. It is recommended that you use
Tripp Lite’s P568-Series High-Speed HDMI cables, as they have been
tested to work with the B126-Series extender products.
