STATUS LEDS
8.1
HDBASET LINK LED
A HDBaseT indicator LED is located next to the RJ45 HDBaseT connector on both the TX and RX variants of
the 866. This is the primary indication to show the CATx cable used is suitable to enable the TX and RX devices
to communicate with one another. When working this LED should be lit solid red. If not lit or blinking it means,
there is a problem with either the transmission medium (CATx cable) or with either the TX or RX unit.
If the LED is not lit it would first be advisable to check that the cabling recommendations of section 9 of this
manual have been adhered to. Test the cable using a cable tester or preferably with the use of a 4K-9000, the
units of the 4K-9000 can then be utilized, through a process of elimination, to identify if there may be a problem
with the TX or RX 866 units.
8.2
HDMI DATA LED
The HDMI data LED is located next to the HDBaseT RJ45 connector as indicated above. This LED shows the
flow of HDMI data and the type of HDMI data.

The DATA LED will only blink or be solidly lit when a complete throughput of HDMI data is possible from the
source to the screen. If the LED is not lit firstly ensure that both the source and screen are powered on and
that the screen is set to the right output.
Ensure the source is outputting a resolution the screen is capable of displaying, this may mean taking the
source and attaching directly to the screen using a HDMI cable. Whilst performing this step it would be worth
checking both HDMI cables being used to see if they are both working.
If these tests are both completed successfully it suggests the problem lies with the TX866, RX866 or the
HDBaseT CATx cable. The easiest way to determine this would be with the use of a 4K-9000 HDBaseT tester
pair.
