12 INTERPRETTING LED STATUS
Four LEDs are presented on the front of the 4K-9000 on both TX and RX variants. This section of the manual
describes how to interpret them and how they aid in showing status of the HDBaseT transmission.
12.1 LINK LED
The HDBaseT link is a status communicated between the TX and RX Valens chips. Embedded within the
HDBaseT protocol, it says that one chip is talking to another. When the link is present the 4K-9000 will
illuminate the LINK LED on the front of the unit. It does not indicate that the link is of good quality just that the
chips are able to communicate. The LINK does not depend on operation mode, it will display if the units are in
HDBaseT mode or Long Reach mode. If the LINK LED is not lit it suggests a problem with the CATx cable, either
in length or build quality, or the problem may lie with either the transmit or receive HDBaseT hardware.
12.2 HDMI LED
The HDMI LED indicates the status of HDMI signal throughput. For the LED to be illuminated HDMI data must
be transmitting completely from source to screen. If the LINK LED is illuminated but the HDMI LED is not it
suggests that there is a problem with the HDMI cabling at either end of the system. It could also be that the
screen is not operational or on the wrong video input, on the other hand the source may not be generating an
output. The final reason, although unlikely as the LINK is lit, could be due to the quality of the CATx cable link.
