Troubleshooting
Overview
The troubleshooting suggestions/strategies provided apply to the DXLink Fiber Transmitters and Receivers unless
otherwise noted.
Five potential types of issues are covered in this chapter:
Basic troubleshooting
Determining HDCP compliance
Power
DXLink Fiber
Network setup
This chapter also provides technical support contact information on page 99.
Basic Troubleshooting
We suggest using the following general list to rule out basic troubleshooting issues.
Check the power indicator LEDs on all of the equipment. If any are not illuminated, see the “Power Issues”
section below.
Check all link and signal connections to make sure everything is physically set up correctly.
Isolate source and destination equipment and cable problems by cabling direct without the DXLink Fiber
units.
If using SEND_COMMANDs – double-check the command and the port number specified and re-send the
command (see page 77).
If any changes have been made, try resetting the unit to the factory defaults (see page 70).

Switchers.
Determining HDCP Compliance
A dark red or orange screen on an output display is the visual cue from the destination device that it cannot display the
HDCP compliant signal from the source device (the authentication process has failed).
Power Issues
Upon power up, the Power indicator LED on the front of the DXLink Fiber units normally illuminates a solid green.
If the Power LEDs on any of the system’s equipment are not illuminated:
Check the power cords.
Check the power connections on the source and destination devices.
