Troubleshooting
If you are unable to get an acceptable image after following the
installation instructions, try the troubleshooting tips below:
Is the external power supply included 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.
Was the power to the connected devices turned o prior to
installation? If not, restart them.
What type of cabling are you using? Inferior cables can result in poor
performance, so it is important to use cables that can support the video
resolution you are trying to obtain. It is recommended you use
Tripp Lite’s P569-CERT Series 4K HDMI cables with Ethernet, as
they have been tested to work with the B119-4K Series Matrix Switch
products.
Test your cables to ensure they are working properly. For example,
connect your HDMI cables between a source and monitor that you know
works to ensure the cable is functioning properly.
Is the switch located in an area that exposes it to higher
temperatures? If the product is overheated, it will not function properly.
What HDMI cable length are you using? The cable connecting an
HDMI source to the switch must be no longer than 15 ft. (4.5 m) in
length. The cable connecting the switch to a display must also be no
longer than 15 ft. in length.
If you are having trouble getting the Terminal Emulation Software to
recognize the switch, you may need to shut down your installation
and start from the beginning. The RS-232 phoenix adapter must be
wired and connected rst. Otherwise, the switch will not be recognized.
If you are still having trouble getting your Terminal Emulation
Software to recognize the switch, check to make sure that your
serial settings are set according to the instructions in the RS-232
Serial Control section of this manual.
