BZBGEAR BG-UM44-100M-KIT PRODUCT MANUAL
IR Control System
The BG-UM44-100M-KIT is not only a matrix switch but also an extender that supports
bi-directional IR control. When the matrix is connected to a HDBaseT receiver through a Cat
5e/6/7 cable, you can control the remote display device (HDBaseT) or input source device
(matrix) through an IR signal transmission. NOTE: The IR signal transmission method is
different from matrix (local) to HDBaseT receiver (remote) and from HDBaseT receiver
(remote) to matrix (local).
At the matrix (local end): the IR signal is a one-to-one transmission. For example, the IR IN
1 port signal of the matrix will emit to the IR OUT port of the HDBaseT Receiver 1, and the
IR IN 3 port of the matrix will emit a signal to the IR OUT port of the HDBaseT Receiver 3.
The IR path from the base unit to the receiver is bonded to the corresponding HDMI port.
The IR IN ALL port of the matrix will emit to all IR OUT ports of HDBaseT receivers
simultaneously. Please see the following connection diagram.

BZBGEAR BG-UM44-100M-KIT PRODUCT MANUAL
Figure 1: IR connection diagram (Matrix end)
At HDBaseT Receiver (Remote end): IR signal follows video switch/change. For
example, the HDMI output signal on the HDBaseT Receiver 1 is from the HDMI INPUT 2
port, so the IR input signal of the HDBaseT Receiver 1 will emit to IR OUT 2 of the matrix.
If the HDMI output signal on the HDBaseT Receiver 3 is from the HDMI INPUT 4 port.
Then, the IR input signal of the HDBaseT Receiver 3 will emit to IR OUT 4 of the matrix
etc. Any HDBaseT receiver’s IR IN signal can output from the IR OUT ALL port of the
matrix and the IR OUT ALL signal of the matrix depends on your IR remote source device.
Please see the following connection diagram.

BZBGEAR BG-UM44-100M-KIT PRODUCT MANUAL
Matrix Audio and RS-232 Introduction
The matrix supports coaxial and analog audio output. The audio signal follows HDBaseT
and HDMI output port. It supports one-to-one transmission. For example, the OUTPUT 1
port audio signal follows HDBaseT and HDMI 1 port, the OUTPUT 2 port audio signal
follows HDBaseT and HDMI 2 port etc.
If the HDMI ARC switch and HDBaseT ARC switch are turned on by ASCII command, the
coaxial and analog audio output can be the returned HDMI or HDBaseT display device’s
audio, the external audio source, or the extracted HDMI source device audio.
Note: multi-channel audio, 3.5 audio has no audio output.
The RS-232 channels are also one-to-one transmission. For example, the RS-232 port of
OUTPUT 1 at the matrix end will transmit to the RS-232 port of HDBaseT Receiver 1, the
RS-232 port of OUTPUT 3 at the matrix end will transmit to the RS-232 port of HDBaseT
Receiver 3 etc. Please see the following connection diagram for reference:

Web GUI User Guide
The matrix can be controlled through a web interface and operation 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:
1. You can get the IP address using the front panel buttons. On the initial OLED
display, press the “MENU” button three times to enter the IP interface and check
the current IP address.
2. You can get the IP address via RS-232 control. Send the ASCII command “ r
ipconfig!” through a Serial Command too which will return the following information:
IP: 192.168.62.109 in the above figure is the IP Address of the Matrix (the IP address is
variable, depending on what the specific machine returns).
For the details of RS-232 control, please refer to “12. RS-232 Control Command”.
Step 2: Connect the TCP/IP port of the matrix to a PC with an ethernet cable (as shown in
the following figure) and set the IP address of the PC to be in the same network as the
matrix.
The computer must be on the same subnet as the matrix to connect successfully. The
device will not be accessible otherwise. The units default IP address is 192.168.1.100,
therefore the computer must be connected to the 192.168.1.x subnet.
To connect to the matrix, open the “Local Area Connection Properties” on the computer.
For Windows users right-click on the internet connection in the lower right corner of the
desktop.
Select “Open Network & Internet Settings”.
Select “Change Adapter Options”.
Right-click on your connection (Wi-Fi or Ethernet) and select “Properties”.
