3. System Connection
3.1 System Applications
As its good performance in control and transmission, the MTX44UH can be widely used
in computer realm, monitoring, large screen displaying, conference system, television
education and bank securities institutions etc.
3.2 Usage Precautions
1) System should be installed in a clean environment and has a prop temperature and
humidity.
2) All of the power switches, plugs, sockets and power cords should be insulated and
safe.
3) All devices should be connected before power on.
3.3 Connection Diagram
4K 4x4 HDBaseT Matrix Switcher
Comm-Tec S.r.l. 9 www.comm-tec.it
3.4 Connection Procedure
1) Connect HDMI sources (e.g. DVD) to HDMI inputs of the MTX44UH with HDMI
cables.
2) Connect auxiliary audio sources to the AUDIO IN ports with audio cables.
3) Connect HDBaseT receivers (e.g. TP513HDR) to the HDBaseT Output ports with
twisted pair.
4) Connect HDMI displays (e.g. HDTV) to HDMI outputs of the MTX44UH or the
receivers with HDMI cables
5) Connect speakers/earphones to AUDIO output ports
6) Connect the RS232 port of control device (e.g. a PC) to the RS232 port of either
MTX44UH or far-end receivers. RS232 signal can be transmitted bi-directionally
between MTX44UH and far-end receivers.
7) MTX44UH can collect IR signal sent by the included IR remote via its built-in IR
sensor or through external IR receiver connected to the IR IN/ IR EYE/ IR ALL IN
port. The IR signal can be transmitted bi-directionally between MTX44UH and far-
end receivers.
8) Connect a DC 24V power adapter and the MTX44UH.
Note: IR receivers connected to IR IN& IR ALL IN should be with carrier. If not, send

command %0900. or %0901.to activate native carrier mode or force carrier mode in the
IR matrix launched between MTX44UH and far-end receivers.
3.5 Connection with TP513HDR
MTX44UH boasts 4 HDBaseT output ports which support PoC solution. Connect the
HDBT output ports of MTX44UH to HDBaseT Receivers supporting PoC (like
TP513HDR) via twisted pair. Plug a power supply to the power port of MTX44UH, the
HDBaseT Receivers will be energized synchronously with PoC solution.
4. System Operations
4.1 Front Panel Button Control
MTX44UH provides with convenient front panel button control. Here we make a brief
introduction to the system operations.
4.1.1 Switching I/O connection
1) To convert one input to an output:
Operation: “input”+“output”+“ENTER”
Example: input 1 to output 2
Note: In default status, 4 IR OUT sockets correspond with 4 HDMI INPUTS. When you
convert an HDMI input to an output, the corresponding IR OUT will be switched
synchronously.
2) To convert an input to several outputs:
Operation: “input” + “output” + “output” +… + “ENTER”
Example: Switch input 2 to output 2, 4

3) To convert an input to all outputs:
Operation: “input” + “ALL” + “ENTER”
Example: Convert input 1 to all outputs
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
4.1.2 EDID Management
MTX44UH features EDID management to maintain compatibility between all devices. It
can be controlled via EDID learning and EDID invoking.
EDID Learning (from output):
One input port learns the EDID data of one output port
Operation: Press “EDID”, “INPUTS”+“OUTPUTS”+“ENTER”.
Example: Input 2 learns EDID data from output 4
All input ports learn EDID data from one output port
Operation: Press “EDID”, “ALL”+“OUTPUTS”+“ENTER”
Example: All input ports learn EDID data from output 4
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
EDID invoking:
There are six types of embedded EDID data. The chart below illustrates the detailed
information of the embedded EDID data:

Press and hold “EDID” for 3 seconds to enter EDID invoking mode, in this mode, use
output buttons 1/2 to switch among the 5 embedded EDID data. Then press “ENTER”
to confirm invoking.
Format: Press and hold “EDID” for 3 seconds, “INPUTS”+“OUTPUTS 1/2”+“ENTER”.
Operations:
Invoke embedded EDID data for one input
Operation: Press “EDID” (hold for 3 seconds to enter in EDID setting status),
“INPUTS”+“OUTPUTS”+“ENTER”.
Example: Set the EDID data of INPUT 2 to the forth type of embedded EDID data:
Press (hold for 3 seconds) or to switch to
the 4th EDID data .
Invoke embedded EDID data for all inputs
Operation: Press “EDID” (hold for 3 seconds to enter in EDID setting status),
“ALL”+“OUTPUTS”+“ENTER”.
Example: Set the EDID data of all input ports to the second type of EDID data:
Press (hold for three seconds) or to switch to
the 2nd EDID data .
Note: If the conversion is successful, indicators of the pressed buttons will blink green
4K 4x4 HDBaseT Matrix Switcher

4K 4x4 HDBaseT Matrix Switcher
Comm-Tec S.r.l. 15 www.comm-tec.it
Note: With this IR remote, MTX44UH can be controlled by the built-in IR, the extended
IR receiver connected to the “IR EYE”/”IR ALL IN” and the IR receiver on the far-end
receiver.
4.2.2 IR Operations
1) IR Matrix Switching
The 4 “IR OUT” ports and the 4 “IR IN” ports on the far-end receivers make up an 4x4
IR matrix. See as below:
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 MTX44UH
itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of MTX44UH.
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.

2) Force Carrier
a) Only if the IR receiver connected to HDBaseT receiver is with IR carrier, can the
received IR signal be transferred to IR OUT port of the matrix.
b) Only if the IR receiver connected to IR ALL IN port of the matrix is with IR carrier,
can the received IR signal 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, 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
Control far-end output device from local
Connect an IR receiver with IR carrier to the IR IN port of MTX44UH, 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 be with 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 MTX44UH. See as below:

RS232 port, or you can just connect any one of the HDBaseT receiver’s RS232 port
with PC (RS232 command can be transmitted to the MTX44UH via the twisted pair). By
using RS232 control software and with right specification settings, you are able to
control the MTX44UH.

Controlled by PC(s) in LAN
Connect MTX44UH, a router and several PCs to setup a LAN (as shown in the
following figure). Set the IP and gateway of MTX44UH to the same as the router’s, then
PCs within the LAN are able to control MTX44UH.
Follow these steps to connect the devices:
Step1. Connect the TCP/IP port of the MTX44UH to Ethernet port of PC with twisted
pair.
Step2. Set the PC’s IP address and gateway to the same as the MTX44UH’s. Do
please remember the PC’s original IP address and gateway.
Step3. Set the MTX44UH’s IP address and gateway to the same IP section as the
router.
Step4. Set the PC’s IP address and gateway as the original one.
Step5. Connect the MTX44UH and PC(s) to the router. PC(s) within the LAN is able
to control the MTX44UH asynchronously.
Then it’s able to control the device via GUI.
4.4.2 GUI for TCP/IP control
MTX44UH provides with built-in GUI for convenient TCP/IP control. GUI allows users to
interact with MTX44UH through graphical icons and visual indicators.
