Link QualityProvides a basic view of our Link Quality from server to client radios.

 

Troubleshooting Steps:

  • If there is no communication to server radio, begin at Step 1.
  • If there is no communication between the client and server radio, begin at Step 6.
  • If there is no communication between client radio and display, begin at Step 10.
  • If communication is intermittent, begin at Step 12.

1. Verify the Green LED on the DC Injector is lit (see illustration above):

2. Check POE cable connections following: How to hook up the DC Injector for Ethernet Bridge Radios, DD2099766. 

3. Power cycle the POE Injector.

4. Locate the server radio. Refer to above image. Is the Power LED on?

5. Verify the ETH Link LED is lit.  This will light up when the radio is able to detect another device such as the network or a computer connected to it.

6. Locate the client radio and verify it has power LED lit.

7. Check for any diagnostic LEDs lit on the client radio at the display.

8. Verify antennas have proper orientation.

9. Power cycle the display/client radio following: Galaxy display using EBR Radio's, No communication to display, Control software reports Low Signal Strength or Communication Error, Client radio or controller is locked up, DD2527710. For further reference, consult How do I reboot my Galaxy or Galaxy Pro Display? DD3511944.

  • If still unable to connect to sign proceed to next section for further troubleshooting or Contact Daktronics.

10. Verify the Ethernet/power cable connection on the back of the display. Connect cables if they are not connected.

11. Power cycle the display following How do I reboot my Galaxy or Galaxy Pro Display?, DD3511944 .

12. If still unable to communication, it's possible communication is intermittent or there is signal noise in the area.  It's also possible there is another device on the network with the same IP.
