Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver
Troubleshooting
Overview
The troubleshooting suggestions/strategies provided apply to the Transmitters and the Receiver, unless otherwise noted.
Five potential types of issues are covered in this chapter:
Basic troubleshooting
Determining HDCP compliance
Power
DXLink connections
Network setup
This chapter also provides technical support contact information on page 86.
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 units.
Check the DIP switch’s toggle settings (see page 34).
SEND_COMMANDs – double-check the command and the port number specified and re-send the command (see page 64).
If any changes have been made, try resetting the unit to the factory defaults (see page 57).
Additional Resources for Troubleshooting Switching Systems
Enova DGX Digital Media Switchers
When the DXLink units are used in conjunction with an Enova DGX Switcher, we suggest checking the troubleshooting information
in that product’s manual.
Enova DVX Solutions
When DXLink units are used in conjunction with an Enova DVX Solution, we suggest: pressing the Status button on the front panel
and using the UP and DOWN navigational buttons to scroll through the menu options to Diagnostic Codes (the codes can be helpful
for technical support if a call is necessary).
Determining HDCP Compliance
A dark red or an orange screen on an output display is the visual cue from DXLink devices that the display device cannot display the
HDCP compliant signal from the source.
Power Issues
Upon power up, the Power indicator LED on the front of the DXLink units illuminates solid green.
If the Power LEDs on any of the system’s equipment are not illuminated:
Check the power cords or DXLink (RJ-45) connection if using power over the DXLink line.
Check the power connections on the switcher if using power over the DXLink line.
Check the power connections on the source and destination devices.
DXLink Power Delivery Issues
Unexpected power interruptions of DXLink Transmitters and Receivers may be caused by the Enova DGX Digital Media Switcher
being powered by single phase power. Connecting a ground wire to the DXLink unit’s chassis and a common earthed ground
(ideally, referenced to the switcher) will stop power interruptions. For information on when and how to attach ground wires to
DXLink units, see page 37.
