3. Product Overview
3.6. TPS Interface
The MMX4x2-HT200 model is built with TPS (Twisted Pair Single) interface which are using HDBaseT
technology. It means the unit receives video, audio, Ethernet, RS-232, and Infrared signals via a single CATx
cable.
TPS Interface Working Modes
The TPS working mode between the transmitter and the receiver is determined by the mode set in them.
Both devices TPS mode settings together determine the finally established TPS transmission mode.
The following TPS modes are defined in the receiver:
▪ Auto: The TPS mode is determined automatically.
HDBaseT: Ideal for high resolution signals up to 4K.
▪
Long reach: Ideal for big distances up to 1080p@60Hz with extended cable lengths.
▪
▪ LPPF1*: Only RS-232 communication is transmitted (@ 9600 baud).
▪ LPPF2*: Only RS-232 (@ 9600 baud) and Ethernet communication are transmitted.
* LPPF: Low Power Partial Functionality.

** If there is valid HDMI/DVI signal is on the TX side, the TPS mode will be HDBaseT on both side. If
the transmitter does not transmits HDMI/DVI signal, the TPS mode will be changed to LPPF2 or LPPF1
automatically. Long reach mode is not available when both sides are set to Auto mode.
When using automatic operation mode selection, the device determines the mode of operation. If both halfs
are set to Auto mode, the source side is the initiator. It will negotiate each state transition with its sink side
partner.
When one of the devices is configured to manual operation mode selection, the other device may be placed
in automatic mode. In this case, the mode transition negotiation is initiated by the host-managed device and
the auto-mode device follows through. The allowed cable lengths and resolutions are listed in the
Extension Distances section.

3.7. Audio Interface
3.7.1. Audio Input Modes
TM
The device can receive embedded audio signal on the HDMI inputs and analog audio signal over the analog
audio input port.
In case of MMX4x2-HT200 model embedded audio signal can be received on the TPS input port as well.
Audio Embedding
The matrix has a built-in audio embedder function what means the audio signal which is received on the
analog audio input port is able to be embedded to the HDMI outputs.
3.7.2. Audio Output Modes
The MMX4x2 series matrix can transmit two types of audio:
▪ Embedded (HDMI) and
Analog balanced stereo audio.
▪
Audio De-embedding
The matrix has a built-in audio de-embedder which means the device is able to de-embed audio from its
HDMI outputs to its analog audio output port.
Auto
ATTENTION! De-embedding function supports 2 channel PCM audio signals only. Other audio formats
are not supported and de-embedding will not be successful.
See a life example about the audio options of the matrix on the next page.
