IR Matrix
The IR signal is sent by corresponding IR remote, then it is transferred to HDBaseT
receiver, then to corresponding zone of the matrix through the twisted pair, finally it is
transferred to IR OUT port and received by controlled device.
Switching Operation
: (4 IR IN ports correspond with 4 HDMI input ports separately in
default mode.)
a) Sending command (reference to
4.3 RS232 Control)
: [x1]R[x2].
x1: Corresponding to the 4 IR OUT ports of the matrix, the IR transmitter connected
to this port can be placed at IR receiving area of output device or MUH44TPR2-N
itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of MUH44TPR2-N.
Example: Send command
“3R2.” to transfer IR signal received from zone 2 to IR
OUT port 3.
4.3 RS232 Control
