Description
①
IR ALL IN
IR control signal input port, connect with IR receiver, pass
through to all the HDBaseT ports to control the remote devices.
②
HDMI
INPUTS
HDMI input ports, 4 in total, type Afemale HDMI connector,
connect with HDMI input source devices.
③
IR OUT
Connect with IR emitter, to send out the IR signal from the
HDBaseT port of the far-end Receiver. These IR OUTs make
up an IR matrix with the IR INs on the HDBaseT receivers,
and all can be switched synchronously with the AV signal,
or separately switching.
④
OUTPUTS
IR IN: Connect with IR receiver, fixed IR input for the output,
cannot be switched separately. It makes up an IR
bi-directional transmission with the IR OUT on the
corresponding HDBaseT receiver.
HDMI: HDMI output port, connect with HDMI output devices.
To split HDMI output for local monitoring.
COAX: HDMI de-embedded digital audio output.
HDBaseT: Works with receivers using HDBaseT technology,
such as TPHD402R, TPHD402PR. It can pass throughAV,
IR and RS232 signal to 60m distance. Meanwhile, it can

provide power for the receivers which support POE.
RS232: RS232 port to communicate with the RS232 port on
corresponding HDBaseT receiver. When controlled by
HDBaseT receiver, the communication protocol must be the
same with MHD44TP.
AUDIO: HDMI de-embedded stereo audio output

2.4 Twisted Pair Cable Connection
The cables for HDBaseT ports must be straight-through ones, using T568A or T568B
standard.
3. System Connection
3.1 Usage Precautions
1) System should be installed in a clean environment and has a prop temperature and
humidity.
2) All of the power switches, plugs, sockets and power cords should be insulated and
safety.
3) All devices should be connected before power on.

3.3 Connection Procedure
1) Connect HDMI sources (e.g. DVD) to HDMI inputs of MHD44TP with HDMI cables.
2) Connect HDMI displayers (e.g. HDTV) to HDMI outputs of MHD44TP with HDMI
cables.
3) Connect speakers/earphones to AUDIO output ports (3p captive screw connectors).
4) Connect the HDBaseT port of HDBaseT receiver and MHD44TP with twisted pair.
5) Connect the RS232 port (9 pin female D) of MHD44TP with control device, e.g. PC.
6) Connect the RS232 port of controlled device to any other RS232 port (3p captive
screw connector) of MHD44TP. The control signal can be transmitted bi-directionally.
7) MHD44TP can be controlled by its built-in IR receiver or through the IR EYE port by
connecting with external IR receiver. The IR signal can also be transmitted
bi-directionally (connect IR OUT port of MHD44TP to IR IN port of other far-end IR
device, and connect IR IN ports of MHD44TP to IR OUT port of other far-end IR
device), and in this mode, we can control MHD44TP remotely.
Note: The IR IN port has built-in infrared carrier receiver.
8) Connect DC48V power adaptor to MHD44TP.
