5.2. TPS Interface
The matrix gives the possibility to route many kinds of signal formats including TPS and other available
interfaces. This chapter is about to present the features and limitations of these interfaces.
ATTENTION!
MMX8x4-HT400MC and MMX8x4-HT420M models have different signal extension
capability. Please check the TPS cable length in the

5.2.1. TPS Working Modes
The TPS working mode between the transmitter and the receiver parties is determined by the mode set in
them. Both parties influence on the setting which determines the final TPS transmission mode.
The following TPS modes are defined in the matrix:

Explanation
Auto The TPS mode is determined automatically.
Ideal for high resolution signals up to 4K but
HDBaseT
with a shorter cable.
Long reach Ideal for big distances up to 1080p@60Hz.
Only RS-232 communication is transmitted

Transmitted signal
* If there is valid HDMI/DVI signal is on the TX side, the TPS mode will be HDBaseT on both side. If the matrix
does not transmits HDMI/DVI signal, the TPS mode will be changed to LPPF1 automatically.

* If there is valid HDMI/DVI signal is on the TX side, the TPS mode will be HDBaseT on both side. If the matrix
does not transmits HDMI/DVI signal, the TPS mode will be changed to LPPF2 automatically. Long reach
mode is not available when both sides are set to Auto mode.
When using automatic operation mode selection, the device uses built-in sensors to determine the mode
of operation. If both parties 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
