DXLink Connection Issues
One method for determining DXLink connection issues is to compare the pattern of the green and yellow DXLink LEDs
on the Transmitter or Receiver against the tables below and then check the suggested items in the Troubleshooting
column in the second table.
DXLink LED Patterns When Connection is Working as Expected
Check the status of the green and yellow DXLink LEDs (on rear of the modules – on lower edge of the Wallplate TX, or
on the front of the Decor Wallplate TX – under customer provided standard decor style cover plate) against the following
table to determine the status of the video signal over the DXLink line. All of the green / yellow patterns in this table
indicate that the unit is working as expected given its current connections. If the LED pattern does not correspond to any
of the green / yellow patterns in this table, check the table below.
DXLink LED Patterns When Connection is Failing
If the green / yellow DXLink LEDs on a unit do not have one of the normal patterns as stated in the table above, check
the patterns in the table below and then check the items listed in the corresponding Troubleshooting column.
