Troubleshooting
If you are unable to get an acceptable image after following the installation
instructions, try the troubleshooting tips:
1. Is the external power supply that came with the product connected
and plugged into a working power source?
For the product to function
properly, the switch must be connected to and receiving power from an
external power supply.
2. Was the power to the connected devices turned off prior to
installation?
If not, restart them.
3. What resolution are you trying to reach?
The B119-003-UHD is
tested to support Ultra High Definition (UHD) video resolutions up to
4096 x 2160 @ 60 Hz and 36-bit Deep Color (12 bits per channel).
4. What length HDMI cable are you using?
The shorter the cable being
used, the higher the resolution you will be able to obtain. If you are not
able to get an acceptable image, try using a shorter cable or lowering your
source’s video resolution or color depth settings. See the
Installation
section in this manual for details on the maximum cable distance.
5. What type of cabling are you using?
Inferior cabling can result in poor
performance, so it is important you use cables that can support the video
resolution you are trying to obtain. It is recommended that you use
Tripp Lite’s P569-XXX-CERT Premium High-Speed HDMI with Ethernet
cables, as they have been tested to work with the B119-003-UHD.
6. Test your cables to ensure they are working properly.
For example,
connect your HDMI cable between a source and monitor that you know
work to see if the cable is functioning.
7. Is the unit located in an area that exposes it to higher
temperatures?
If the product is overheated, it will not function properly.
8.
If you are having trouble getting your Terminal Emulation Software to
recognize the switch, you may need to shut down your installation and
start from the beginning.
9.
If you are still having trouble getting your Terminal Emulation Software to
recognize the switch, check to make sure your serial settings are set according
to the instructions in the
RS-232 Serial Control
section of this manual
