Step 7. MS-44HDBT can be controlled by its built-in IR receiver or the external IR
receiver connected to the IR EYE port. IR signals can be transmitted bi-directionally
between MS-44HDBT’s IR OUT/ IR IN and HDBaseT Receiver’s IR IN / IR OUT.
In this mode, we can control MS-44HDBT remotely with the MHD44TP’s IR
Remote.
Note: The IR IN port has built-in infrared carrier receiver.
Step 8. Connect a DC48V power adaptor to the power port of MS-44HDBT.

IR control options.
Control of the far-end output device from the MS-44HDBT.
Control the local input/output device remotely.
Control the MS-44HDBT locally/remotely.
The MS-44HDBTcan be controlled by its built-in IR receiver or through the IR EYE
port by connecting with an extended IR receiver. It can also be controlled remotely
by a far-end IR device through the twisted pair.
5.2.1 Usage of IR Remote
Input channels, range from 1~4, IR signals are
switched synchronously with HDMI signal
correspondingly.
Menu buttons, button

corresponding output channels
Example: Press “3”, “THROUGH”, the result will
be IN 3OUT 3. Press “ALL”, “THROUGH”, the
result will be: 11, 22, 33, 44
Output channels, range from 1~4.

5.2.2 IR Operations
1) IR Matrix Switching
The 4 “IR OUT” ports make up a 4x4 IR matrix with the “IR IN” ports of the far-end
receivers. See as below:
Control of Local Devices or the MS-44HDBT Remotely
The IR signal is received from a corresponding IR remote, then transferred to the
HDBaseT receiver, then to corresponding zone of the matrix through the twisted pair
and finally transferred to the IR OUT port and received by the controlled device.
Switching Operation:
a) Sending command (reference to 5.3 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 the IR receiving area of the output
device or the matrix itself.
x2: Corresponding to the zone number (IR signal transmit to the HDBaseT receiver
and then gets to the HDBaseT port of this zone via the twisted pair)
E.g.: Command “3R2.” means to transfer IR signal received from zone 2 to IR
OUT port 3.
b) Using the IR remote: Input channelbutton IROutput channel
Input channel: the 4 INPUT buttons, corresponding to the 4 IR OUT ports of the
matrix.

AVG-MS-44HDBT
Output channel: the 4 OUTPUT buttons, corresponding to the zone (receive IR
signal from HDBaseT receiver with IR IN port connects with IR receiver) number
of the matrix.
E.g.: Press buttons “3”, “IR”, “1” in order, “3” in OUTPUTS area, “1” in INPUTS
area, to transfer IR signal received from zone 3 to IR OUT port 1.
Note: When switching all the 4 IR input signal channels to a same IR out
channel, it is not able to control the controlled device(s) at the same time.
2) IR Carrier Enforcing
a) Only if the IR receiver connected with HDBaseT receiver has IR carrier, the
received IR signal can be transferred to the IR OUT port of the matrix.
b) Only if the IR receiver connected with IR ALL IN port of the matrix is with IR
carrier, the received IR signal can then be transferred to 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, you need to send the command “%0901.”, and then
you are able to transfer the IR signal to IR OUT port.
3) Control far-end output devices from local IR Port
When you need to control a remote display from local, the IR receiver used must
have an IR carrier. The IR signal is transferred to the corresponding zone connected
with HDBaseT receiver connected with the IR transmitter. When the IR receiver is
connected to IR ALL IN port, the IR signal can be finally transferred to all the 4 IR
transmitters connected with HDBaseT receivers.
As per the figure below:
Controlling a far-end device from Local Matrix location

AVG-MS-44HDBT
1) Controlling far-end devices through the IR ALL IN port
The IR signal received from the IR ALL IN port will be transmitted to all the four far-
end HDBaseT receivers connected to HDBaseT ports of the MS-44HDBT. See as
per figure below:
Controlling far-end devices through the IR ALL IN port
2) Controlling a local device from far end remote
A user can control local devices such as DVD, matrix etc. remotely. When using, the
IR signal received from the HDBaseT receiver it will be transmitted to the
corresponding IR OUT port of the MS-44HDBT. See below:
Control of local device from remote
3) Controlled by a Third-party IR Control Device
Use the included IR converting cable (see as below), connect the 3-pin end to the IR
input port of the MS-44HDBT, the 2-pin end to the IR output port of the third-party
control device. The IR signal is able to be transmitted via the twisted pair, and finally
gets to the remote output device.

AVG-MS-44HDBT
5.3 RS232 Control
5.3.1 RS232 Commands
Through the RS232 communication port, a user can control a far-end device whose
baud rate is 2400, 4800, 9600, 19200, 38400, 57600 or 115200. Default setting of
the MS-44HDBT: baud rate is 9600, data bit is 8, stop bit is 1 and parity bit is none.
