3.3 Connection Procedure
1) Connect HDMI sources (e.g. DVD) to HDMI input ports of the Matrix Switcher via
good quality HDMI cables.
2) Connect the Pre-Installed CAT5e/CAT 6 cable infrastructure to Matrix Switcher
and HDBaseT receivers via good quality patch leads.
3) Connect HDTV to HDMI output port via HDMI cable.
4) Plug in an HDMI cable in to each of HDBaseT Receiver and connect to the local
display [HDTV].
5) Connect AVR amplifier to SPDIF output port or via the Toslink optic fibre cable.
6) Connect speaker to L&R (RCA) output port via audio cable.
7) Plug the IR Receivers 3.5mm jack into the IR IN sockets on HDBaseT Receivers
and plug in the IR Emitters to the IR OUT sockets (1~8) on Matrix Switcher to
make up as IR Matrix.
8) Plug the phoenix connector in to the RS232 socket on the matrix, this will enable
the Matrix Switcher to be controlled via a PC.
9) Plug in a Patch lead from the router in to the Ethernet port on Matrix Switcher to
control Matrix Switcher by TCP/IP protocol.
10) Plug in the power supply cord. Once all components have been connected and
the installation is completed, switch on the mains supply at the socket.
Note:
1. Connect HDBT ports of Matrix Switcher and far-end HDBaseT Receivers 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 features 7 HDBaseT outputs which support PoC technology. Plug
in the 7 RJ45 patch leads in to the HDBT outputs and connect to the pre-installed
infrastructure. Connect the 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 Receivers will be powered by the Matrix Switcher.

4. System Operations
4.1 IR Control
IR Remote
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.
①
Standby button:
Press it to enter/ exit standby mode.
②
INPUTS:
Input channel selection buttons, range from 1~8.
③
OUTPUTS:
Output channel selection buttons, range from 1~8.
④
Menu buttons:
 ALL: Select all 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.
1. To convert one input to an output:
Example: Input 1 to Output 3
→ Press INPUTS 1 + OUTPUTS 3
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, 4 and 5
→ Press INPUTS 2 + OUTPUTS 3 + OUTPUTS 4 + OUTPUTS 5
3. To convert an input to all outputs:
Example: Input 1 to all Outputs
→ Press INPUTS 1 + ALL + ENTER
By using IR & HDBaseT transmission technology, the 4K HDBaseT Matrix Switcher 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.
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 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:

ALFATRON ALF-MUH88E

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:

Receiver connected to IR IN of the receiver is not with carrier.
 Multiple to Multiple: (IR Matrix)
The 8 “IR OUT” ports and the 7 “IR IN” ports on the far-end receivers make up a 7 x
8 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 4.2 RS232 Control): [x1]R[x2].
x1: Corresponding to the 8 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.
4.2 RS232 Control
RS232 connection
Except the front control panel, the Matrix Switcher can be controlled by far-end
control system through the RS232 communication port. This RS232 communication
port is a 3-pin phoenix connector. User can use the RS232 cable (Phoenix to 9-pin
