Troubleshooting
If you are unable to get an acceptable image after following the
installation instructions, try the troubleshooting tips below.
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, 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. 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. It is
recommended that you use P568-Series High-Speed HDMI cables,
as they have been tested to work with the B119-Series Matrix Switch
products.
5. Once these settings are updated, the Terminal Emulation Software
will recognize the switch, allowing you to enter commands to control
it with. The following table lists the available commands.
Command Action
sw[x] [n]
Switches the source being displayed on the selected
output. [x] is the output (1, 2, 3, or 4) and [n] is the
desired source (A, B, C, or D). For example, a command
of sw1 B would display source B on output 1.
PWD
Turns power to the switch on/off.
STE
Displays the current output state, showing which source
is being displayed on each output.
