Instruction 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 102.
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 on the next page.
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 43).
SEND_COMMANDs – double-check the command and the port number specified and re-send the
command (see page 78).
If any changes have been made, try resetting the unit to the factory defaults (see page 69).
Additional Resources for Troubleshooting Endpoint 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
Instruction 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.
