ST-NMXB44H150 18Gbps 4 x 4 HDBaseT (150M) Matrix

The 18Gbps 4x4 HDBaseT(150M) Matrix can connect four HDMI™ sources to eight displays. 
It features four HDMI™ outputs and each HDMI™ output is mirrored to provide a CAT-Cable 
output which runs simultaneously. HDBaseT output can extend video transmission distance 
up to 492ft/150m (1080P) or 394ft/120m (4K2K) via a single CAT 5e/6/7 cable and the video
resolution is up to 4K2K@60Hz 4:4:4.
Audio de-embedded to analog and coaxial audio is supported. Each HDMI™ output supports 
4K2K to 1080P downscaler independently.
The product supports IR matrix. The IR signal is one-to-one control at the Matrix end, but the 
IR signal follows HDMI™ video channel at the HDBaseT Receiver end. 
The product provides an intuitive set of front panel with OLED screen and supports control 
via front panel buttons, IR remote, RS-232, LAN, and Web GUI.

IR Control System

The product is not only a matrix switch but also an extender. It supports bi-directional IR 
control. When Matrix is connected to HDBaseT Receiver through Cat 5e/6/7 cable, you can 
control remote display device (HDBaseT) or input source device (Matrix) through IR signal 
transmission. But you must 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 doesn’t 
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.

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.

IR Cable Pin Assignment

RS-232 Control Command

The product also supports RS-232 control. You need a serial cable with RS-232 male head 
and DB9 transfer USB male head. The RS-232 head of the serial cable is connected to the RS
232 control port with DB 9 at the rear of the Matrix, and the USB head of the serial cable is 
connected to a PC. The connection method is as follows:
