1. Introduction
1.1 Introduction to MHD44TP
MHD44TP is a 4x4 HDBaseT matrix switcher, including 4 HDMI inputs, 4 HDBaseT
outputs, 2 local HDMI outputs, 4 de-embedded stereo audio & 4 de-embedded digital
audio outputs. It enables cross-point switching from any input to any output, and
supports high resolution 1080P, HD3D. The HDBaseT output works with TPHD402PR,
to transmit HDMI, IR, RS232 and POE over a Cat5e/Cat6 cable. And its transmission
distance can up to 60 meters.
1.2 Features
HDTV compatible with High Definition Transmission resolution up to
1920*1200@60Hz, support 1080P, HD3D.
HDCP Compliant and DVI compatible, supporting DVI1.0.
Powerful EDID&HDCP management.
HDBaseT outputs, to transmit HDMI, IR&RS232 to 60 meters long distance over a
Cat5E/6 cable.
POE supports, provides power for all the receivers connected to HDBaseT outputs.
Supports multiple control ways, including front panel, RS232, IR and optional TCP/IP
control (works with PTNET).
IR OUT signal switching follow with video signal, also can be broken away from
video switching.
Supports remote control from receiver by IR&RS232.
Supports centralized IR control to control all the remote display devices.
Supports PCM, Dolby, and DTS5.1 surround.
LCD indicator shows connection status, switching status, HDCP status, and output
resolution.

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
Type A female HDMI connectors.
③
IR OUT
Connect with IR transmitter, to send out the IR signal from
the HDBaseT port. These IR OUTs make up a 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. It makes up an IR
transmission with the IR OUT on the corresponding
HDBaseT receiver.
HDMI: 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
