Subject: What does a flashing/blinking LINK LED light mean?

Explanation:  Our extender kits are comprised of a transmitter (TX) and a receiver (RX) which each have a LINK LED light. 

 

These LED lights should normally be illuminated solid when a good (working) CAT5e or better cable is connected between the TX and RX and the units are capable of passing signal to each other. If you notice that the LINK LED is flashing, this might mean there is a communication error between the TX and RX. Please consider trying the troubleshooting below:

  1. Try another known working CAT5e or cable between the TX and RX. You can use a cable of any length above 3 ft. / 1 m. A great way to be certain the cable works is to test with another working extender kit, if available.

  2. If another cable does not provide a solid link light, try moving the units away from their current location and test them in an environment away from any sources of electromagnetic interference, such as electrical wires, large appliances, walkie-talkies, or other radio devices. Unshielded cables can pick up interference from these devices and this can cause link issues.

  3. Another great test if you have another working kit is to swap the questionable kit with the kit that is known to be working.

  4. The HDR-EX series units feature a built-in HDBaseT tester.
