Broaman: How to quickly check if your MUX-22 is working

To do that please follow the instructions:

  1. Connect COM port only locally on single device using simplex fiber cable - this will create internal loopback for all video channels and channel 1 will appear on output 5, channel 2 on output 6 and so on.

  2. Please do the same for each device.

This will allow us to see which device has a problem and if it's a problem with transmitter or receiver.

Only loopback the Com 1 port as shown in the panel diagram below.
