This blue LED will illuminate when at least one optical cable is
connected and has successfully detected and sent, between the
Transmitter and Reciever, a signal containing video or audio data.
2 ERROR
This red LED will illuminate when there appears to be an error in the
input signal data rate that is higher than 75MHz or the HDMI output
signal is not compatible.
3 HDMI INPUT
Connect to an HDMI input source such as a DVD or Blu-ray player
with a HDMI cable.
4 OPTICAL LINK
This blue LED will illuminate when the optical cable is connected
and has successfully detected and communicated data between
