AVG-UHMS44
5.2.2. IR Operations
1. IR Matrix Switching
The 4 “IR OUT” ports and the 4 “IR IN” ports on the far-end receivers make up a
4x4 IR matrix. See as below:
IR Matrix
The IR signal is sent by the corresponding IR remote, then it is transferred to the
HDBaseT receiver, then to the corresponding zone of the matrix through the
twisted pair, finally it is transferred to the IR OUT port and received by the
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
AVG-UHMS44 itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with
IR IN port connects with IR receiver) number of AVG-UHMS44.
Example: Send command “3R2.” to transfer IR signal received from zone 2 to
IR OUT port 3.
Note: When switching all the 4 IR input signal channels to the same IR out
channel, it is not able to control the 4 far-end IR receivers at the same time.

AVG-UHMS44
2. Force Carrier
a. Only if the IR receiver connected to HDBaseT receiver has an IR carrier, can
the received IR signal be transferred to the IR OUT port of the matrix.
b. Only if the IR receiver connected to the IR ALL IN port of the matrix has IR
carrier, can the received IR signal be transferred to the IR OUT port of the
matrix.
If the IR receiver connected with HDBaseT receiver or IR ALL IN port of the
matrix is not with IR carrier, send the command “%0901.” to enter infrared
carrier enforcing mode, and then IR signal can be transferred to IR OUT port.
3. IR control setting
Controlling a far-end output device from local point
Connect an IR receiver with IR carrier to the IR IN port of AVG-UHMS44,
users can control far-end output displayer via its IR remote from local.
In that case, the IR signal is transferred via twisted pair. Only the
corresponding IR OUT port can emit control signals to the remote display.
See the figure below:
Control far-end device from local
Note: The IR receiver connected to IR IN must have an IR carrier.
The IR signal received from IR ALL IN port will be transmitted to all the 4 far-
end HDBaseT receivers connected to HDBaseT ports of the AVG-UHMS44.
See as below:

AVG-UHMS44
Control far-end device through IR ALL IN port
Controlling a local device from a remote receiver location
It is also possible to control local source devices with their IR remote from
remote too. When using, the IR signal received by the HDBaseT receiver will
be transmitted to the corresponding IR OUT port of the AVG-UHMS44. See
below:
Control local device from remote
