Description
①
IR ALL IN
Input port for IR control signal, connect with IR receiver, deliver
IR signal to all the HDBaseT ports to control the remote
devices.
②
HDMI
INPUTS
HDMI input ports, 4 in total, type A female HDMI connector,
connect with HDMI input source devices.
③
IR OUT
Connect with IR transmitter, to emit the IR signal sent from the
HDBaseT ports of the far-end Receiver. These IR OUTs make
up an IR matrix with the IR INs on the HDBaseT receivers, and
all IR signals can be switched synchronously with the AV
signal, or separately switched.
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 displayers,
deliver same input signals with HDBaseT ports, split HDMI
output for local monitoring.
COAX: HDMI de-embedded digital audio output.

HDBaseT 4x4 Matrix Switcher-N

HDBaseT: Works with HDBaseT receivers, such as
TPHD402R, TPHD402PR. It can extend AV, IR and RS232
signal to 60m distance. Meanwhile, it can provide power for
the receivers which support PoC.
RS232: Serial 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-N.
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. The connectors can be T568Aor T568B, but both sides must be the same.
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
safe.
3) All devices should be connected before power on.
