Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
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.
Note: For installations where the DXLink Twisted Pair device could lose connectivity for an extended period
of time (greater than 5 minutes), the Offline Recovery Mechanism is an option that allows the device to detect
its offline state and reconnect to a Master (see page 66).
LED Patterns – Working as Expected
Green Yellow LED Pattern Description
Solid green Solid yellow The DXLink link is established and the video stream is passing HDCP protected
content.
Solid green Flashing yellow The DXLink link is established and the video stream is passing unprotected content.
Solid green Off The DXLink link is established but no video content is being passed.
Off Off The DXLink link is not established and the accompanying DXLink unit is not powered
on or is not connected.
