There are four IR emitter sockets for connecting IR TX cable. The IR signal is
reversed to HDMI signal. That is, when user is watching the STB signal which
is connected to input3, the IR signal will go to the IR_TX3 socket.
Because the each IR emitter socket is related to one HDMI input port. Be sure
that the IR TX cable connected to the IR emitter socket and stick the IR emitter
to the IR window of the HDMI source device which has been connect to the
related input port. For example, STB connected to input1, and then if user
wants to control the STB via the IR call back system, plug the IR TX jack to the
IR emitter socket source1. And, stick the IR emitter near to the IR window of
the STB.
There are four IR receiver sockets for connecting IR RX cable. The IR TX
signal is forward to HDMI signal.
Press the output1 selection button and output4 selection button at the same
time for about 3 seconds. After all the output LEDS flash, the matrix go into the
IR TX matrix switch mode. The each IR receiver socket is related to one HDBT
output port. Be sure that the IR RX cable connected to the IR receiver socket
and stick the IR emitter to the IR window of the HDMI sink device which has
been connect to the related HDBT receiver. For example, HD LCD connected
to HDBT receiver which connected the HDBT output1 of the MX0404-HE1,
and then if user wants to control the HD LCD via the IR system, plug the IR RX
jack to the IR receiver socket 1. And, stick the IR emitter near to the IR window
of the HD LCD, go into IR TX matrix mode, press output1 button to select the
first IR channel.
