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 Local Devices or MHD44TP-N Remotely
The IR signal is received from corresponding IR remote, then transferred to HDBaseT
receiver, then to corresponding zone of MHD44TP-N through the twisted pair, finally
transferred to IR OUT port and received by 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 MHD44TP-N, The IR transmitter connected
to this port can be placed at IR receiving area of output device or MHD44TP-N itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN port
connects with IR receiver) number of MHD44TP-N.
E.g.: Command “3R2.” means to transfer IR signal received from zone 2 to IR OUT port 3.
b) Using IR remote: Input channelbutton IROutput channel
Input channel: the 4 INPUTS buttons, corresponding to the 4 IR OUT ports of
MHD44TP-N.
Output channel: the 4 OUTPUTS buttons, corresponding to the zone (receive IR
signal from HDBaseT receiver with IR IN port connects to IR receiver) number of
MHD44TP-N.
E.g.: Press buttons “3”, “IR”, “1” in order, “3” in OUTPUTS area, “1” in INPUTS area,
Page 16
HDBaseT 4x4 Matrix Switcher-N
PTN Electronics Limited 12 www.PTN-electronics.com
to transfer IR signal received from zone 3 to IR OUT port 1.
Note: When switch 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 is with IR carrier, the
received IR signal can be transferred to IR OUT port of MHD44TP-N.
b) Only if the IR receiver connected with IR ALL IN port of MHD44TP-N is with IR
carrier, the received IR signal can be transferred to IR OUT port of MHD44TP-N.
If the IR receiver connected with HDBaseT receiver or IR ALL IN port of MHD44TP-N
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 device from local
When need to control a remote displayer from local, the IR receiver used must be with
IR carrier. The IR signal is transferred to the corresponding zone connected with the
HDBaseT receiver which is 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 the figure below
Control far-end device from Local
Page 17
HDBaseT 4x4 Matrix Switcher-N
PTN Electronics Limited 13 www.PTN-electronics.com
4) Control far-end device through IR ALL IN port
The IR signal received from IR ALL IN port will be transmitted to all the four far-end
HDBaseT receivers connected to HDBaseT ports of MHD44TP-N. See as below:
Control far-end device through IR ALL IN port
5) Control local device from remote
User can control local device such as video source device, MHD44TP-N etc remotely.
When using, the IR signal received from the HDBaseT receiver will be transmitted to the
corresponding IR OUT port of MHD44TP-N. See below:
Page 18
HDBaseT 4x4 Matrix Switcher-N
PTN Electronics Limited 14 www.PTN-electronics.com
Control local device from remote
6) Controlled by a Third-party IR Control Device
Use the included IR converting cable (see as below), connect the 3-pin end to IR input
port of MHD44TP-N, the 2-pin end to IR output port of the third-party control device.
Then the IR signal is able to be transmitted via the twisted pair, and finally gets to
remote output device.
5.3 RS232 Control
5.3.1 RS232 Commands
Through the RS232 communication port, user can control a far-end device whose
bound rate is 2400, 4800, 9600, 19200, 38400, 57600 or 115200. Default setting of
MHD44TP-N: bound rate is 9600, data bit is 8, stop bit is 1 and parity bit is none.
Communication protocol: RS232 Communication Protocol
Baud rate: 9600 Data bit: 8 Stop bit: 1 Parity bit: none

input (value: I) or output (value: O). [X] is
the number of one port, if the value of X is
ALL, it means all ports. [Z] is for working
status (value: 1 or 0).
Y=I & Z=1, means the input port is
compliant with HDCP.
Y=O & Z=1, means output with HDCP.
Y=I & Z=0, means the input port is not
compliant with HDCP.
Y=O & Z=0, means output without
HDCP.

/+[Y]/[X]:******.
Set communication between PC and
HDBaseT receiver.
① Y is for RS232 port (connect with
RS232 port of HDBaseT receiver)
Value = 1,2,3,4,5,A,B,C,D,E,F,G or H
The value of Y is defined into the
following meanings (in a given baud
rate depended by the value of X):
a. Y = 1, 2, 3 or 4, send this command to
the corresponding HDBaseT receiver
to control far-end device.
b. Y = 5, send this command to all
HDBaseT receivers to control all
far-end devices.
c. Y = A, B, C or D
d. Y = E, F, G or H
For items c or d, send this command,
it will be saved to MHD44TP-N but
taken without action to corresponding
HDBaseT receiver. And its command
function will be effective almost at the
same time when you send the
command PWON (for item c) or
PWOFF (for item d).
Note:
A & E are for port 1.
B & F are for port 2.
C & G are for port 3.
D & H are for port 4.
② X is for bound rate (Value ranges
from 1 to 7, 1 is for 2400, 2 for 4800, 3
for 9600, 4 for 19200, 5 for 38400, 6
for 57600 and 7 for 115200)
③ ***** is for data (max 48 Byte)
④ The symbol “.” is the end of one
command. If there are some symbols
of “.” in one command, this case is
allowed and the last one is the end.

PTN Electronics Limited 23 www.PTN-electronics.com
Controlled by PC(s) in LAN
MHD44TP-N can be connected with a router to make up a LAN with the PC(s), this
make it able to be controlled in a LAN. Make sure MHD44TP-N’s IP section is the same
with the router. Please connect like the following figure for LAN control.
Same IP section
but cannot be
192.168.0.178
Page 28
Step1. Connect the TCP/IP port of MHD44TP-N to Ethernet port of PC with twisted
pair.
