7. IR Control System
The ALF-MUH44E is not only a matrix switcher but also an extender. It supports bi-
directional IR control; When Matrix is connected to HDBaseT Receiver through Cat 6/7
cable, you can control remote display device (HDBaseT) or input source device (Matrix)
through IR signal transmission. Note that the IR signal transmission method is different
from the method from Matrix (local) to HDBaseT Receiver (remote) and from HDBaseT
Receiver (remote) to Matrix (local).
At the Matrix end (Local end): the IR signal is one-to-one transmission. For example, the
IR IN 1 port signal of the Matrix will emit to IR OUT port of the HDBaseT Receiver 1, and the
IR IN 3 port signal of the Matrix will emit to IR OUT port of the HDBaseT Receiver 3. It does
not follow the video switch to change. IR IN ALL port signal of the Matrix will emit to all IR OUT
ports of HDBaseT receivers simultaneously. Please see the following connection diagram.

- 9 / 28 -
Alfatron ALF-MUH44E
At HDBaseT receiver (Remote end): IR signal follows video switch to change. For example,
the HDMI output signal on the HDBaseT Receiver 1 is from the HDMI INPUT 2 port, so IR
input signal of the HDBaseT Receiver 1 will emit to IR OUT 2 port of the Matrix. The HDMI
output signal on the HDBaseT Receiver 3 is from the HDMI INPUT 4 port. Then, IR input
signal of the HDBaseT Receiver 3 will emit to IR OUT 4 port of the Matrix etc. Any of
HDBaseT Receiver’s IR IN signal can output from IR OUT ALL port of the Matrix and the
IR OUT ALL signal of the Matrix depends on your IR remote of source device. Please see
the following connection diagram.

Note: When the angle between the IR receiver and the remote control is ± 45 °, thetransmission distance is 0-5 meters;
when the angle between the IR receiver and theremote control is ± 90 °, the transmission distance is 0-8 meters.
9. EDID Management
This ALF-MUH44E has 21 factory defined EDID settings, 2 user defined EDID modes and 8
copy EDID modes. You can select defined EDID mode or copy EDID mode to the input port
through panel button, RS-232 control or Web GUI.
Panel button operation: On the initial OLED display screen, press “MENU” button to enter the
EDID settings interface, press “UP/DOWN” button to select the required EDID, then press
the “ENTER” button to enter “Copy to Input:” interface. Then press “UP/DOWN” button to select
the input port you need to set, and press “ENTER” button again to confirm this operation.
RS-232 control operation: Connect the Matrix to a PC with a serial cable, then open a
Serial Command tool on PC to send ASCII command “s edid in x from z!” to set EDID. For
details, please refer to “EDID Setting” in the ASCII command list of “11. RS-232 Control
Command”.
Web GUI Operation: Please check the EDID management in the “Input page” of “10. Web

10. Web GUI User Guide
The Matrix can be controlled via Web GUI, the operation method is shown below:
Step 1: Get the current IP Address.
The default IP address is 192.168.1.100. You can get the current Matrix IP address in two ways:
The first way: You can get the IP address via panel buttons. On the initial OLED display, press
“MENU” button three times to enter the IP interface and check the current IP address.
The second way: You can get the IP address via RS-232 control
. Send the ASCII command
“r ipconfig!” through a Serial Command tool, the feedback information as shown below:
IP:192.168.61.103 in the above figure is the current Matrix IP address (this IP address is
variable, depending on what the specific machine returns).
For the details of RS-232 control, please refer to “11. RS-232 Control Command”.
Step 2: Connect the TCP/IP port of the Matrix to a PC with an UTP cable (as shown in the
following figure) and set the IP address of the PC to be in the same network segment with
the Matrix.
