mains supply at the socket.
Note:
1. Connect HDBT ports of Matrix Switcher and far-end HDBaseT Receiver with
straight-through cable.
2. IR receivers connected to IR 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 Matrix Switcher and far-end HDBaseT Receiver.
3.4 Connection with HDBaseT Receiver
The Matrix Switcher has 3 HDBaseT outputs which support PoC technology. Plug in the
4 RJ45 patch leads in to the HDBT outputs and connect to the pre-installed
infrastructure. Connect HDBaseT Receivers to the pre-installed cabling via additional
patch leads. Plug the power supply in to the power socket on the matrix, the HDBaseT

4. System Operations
4.1 IR Control
IR Remote Description
Connect an IR receiver to the IR EYE port of the Matrix Switcher, users can control it
through the included IR remote. Here is a brief introduction to the IR remote.
①Standby button, press it to enter/ exit standby mode.
②Input channels, range from 1~4, corresponding IR
signal switched synchronously when switching input
channels.
③OUTPUTS
In normal mode: output channel selection buttons.
In EDID invoking mode: press button 1/2 to switch
among the 5 embedded EDID data.
④Menu buttons: ALL, EDID, CLEAR and ENTER.
ALL: Select all inputs/ outputs.
EDID management button: Enable input port to
manually capture and learn the EDID data of
output devices.
CLEAR: Withdraw an operation like switching
output channel, learning EDID data before it
comes into effect. Meanwhile, the matrix will
return to the previous status.
ENTER: Confirm operation. Press and hold it for
3 seconds to enter in Inquiry mode.
Note: With this IR remote, the Matrix Switcher can be
controlled by the built-in IR, the extended IR receiver
connected to the IR EYE and the IR receiver on the far-end
receiver.
By using IR & HDBaseT transmission technology, the 4K Home Distribution Hub Kit has
some functions as follows:
1) Control far-end output device from local.
2) Control local input/output device remotely.
3) Control the Matrix Switcher locally/remotely.

4K 4x4 HDBaseT Matrix Switcher
Comm-Tec S.r.l. 15 www.comm-tec.it
Usage of IR Remote
4.1.2.1. Switching I/O connection
1. To convert one input to an output:
Example: Input 1 to Output 3
→Press INPUTS 1 + OUTPUTS 3 + ENTER
NOTE:
Default status, on first boot up this matrix assigns the IR outputs to the
corresponding HDMI input, meaning, IR out 1 is directly associated to HDMI
input 1 and so on. When you switch an HDMI input to a different output, the
corresponding IR OUT will be switched synchronously to allow the IR
commands to be sent from the select zone back through the Matrix
Switcher to the source.
2. To convert an input to several outputs:
Example: Convert Input 2 to Output 3 and 4
→Press INPUTS 2 + OUTPUTS 3 + OUTPUTS 4 + ENTER
3. To convert an input to all outputs:
Example: Input 1 to all Outputs
→Press INPUTS 1 + ALL + ENTER
4.1.2.2. EDID Management
The 4K Home Distribution Hub Kit features EDID management that enables the Matrix
Switcher to learn the EDID of all sources and sink devices. The Matrix Switcher can
learn the EDID from any device or be programmed to assign an EDID to the mirror port
through EDID Invoking.
1. EDID Learning（from output）:
One input port learns the EDID data of one output port:
Example: Input 2 learns EDID data from output 4
→Press EDID + INPUTS 2 + OUTPUTS 4 + ENTER
All input ports learn EDID data from one output port:
Example: all input ports learn EDID data from output 4
→Press: EDID + ALL + OUTPUTS4 + ENTER
2. EDID invoking:
There are five types of embedded EDID data. The chart below illustrated 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, INPUT# +OUTPUT1/2 + ENTER.
Invoke embedded EDID data for one input:
Example: set the EDID data of input 2 to the fourth type of embedded EDID data
→Press EDID (hold for 3 seconds to enter in EDID setting status) + INPUTS 2 +
OUTPUTS1 or 2 + ENTER
4.1.2.3. Clear operation
When you switch output channel, learn EDID data, or set EDID data, press “Clear”
button to EXIT the operation before you press “ENTER” to carry it on. When you press
it, the Matrix Switcher will return to the previous status.
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 Switcher.
b) Only if the IR receiver connected to the Matrix Switcher is with IR carrier, can the
received IR signal be transferred to IR OUT port of the Matrix Switcher.
If the IR receiver connected to HDBaseT receiver or the Matrix Switcher is without
an IR carrier signal, send the command “%0901.” to enter infrared carrier enforcing
mode, and then IR signal can be transferred to IR OUT port.
Control Far-end Device locally
Connect an IR receiver to IR IN on the Matrix Switcher, and use the IR Remote of far-
end device to control the device locally.
Connect an IR receiver with IR carrier to the IR IN port of the Matrix Switcher; 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:

4K 4x4 HDBaseT Matrix Switcher
Comm-Tec S.r.l. 17 www.comm-tec.it
Control far-end device from Local
Note: The IR receiver connected to IR IN must be with IR carrier
Control Local Device Remotely
Connect IR receiver(s) to IR IN on far-end HDBT receiver(s), and IR Emitter(s) to IR
OUT port of the switcher, and use the IR Remote of local source to control the device
remotely.
1 to 1:
Connect an IR receiver to IR IN on far-end HDBT receiver, and an IR Emitter to IR
OUT port of the switcher. Use the IR Remote of local source to control the device
remotely. See below:
Control local device from remote
Note: Send command “%0901.” to enter infrared carrier enforcing mode if the IR
Receiver connected to IR IN of the receiver is not with carrier.

Multiple to Multiple: (IR Matrix)
The 4 “IR OUT” ports and the 3 “IR IN” ports on the far-end receivers make up a
4x3 IR matrix. See as below:
IR Matrix
The IR signal is sent by 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:
Sending command (reference to 4.3 RS232 Control): [x1]R[x2].
x1: Corresponding to the 4 IR OUT ports of the Matrix Switcher, the IR transmitter
connected to this port can be placed at IR receiving area of output device or the
Matrix Switcher itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of the Matrix Switcher.
→ Example: Send command “3R2.” to transfer IR signal received from zone 2 to IR
OUT port 3.
