3.4. TPS Matrix Concept
MMX6x2-HT is the first stand-alone matrix switcher with HDBaseT
TM
(TPS) technology in Lightware’s product
range. 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.
Summary of the Interfaces
3.5. TPS Interface
3.5.1. 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:
▪
Auto:
The TPS mode is determined automatically.
▪
HDBaseT:
Ideal for high resolution signals up to 4K but with a shorter cable.
▪
Long reach:
Ideal for big distances up to 1080p@60Hz.
▪
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
Above settings refer to the matrix. The table below details the system's state with regard to mode selection
behavior for all possible combinations for both ends of the link:

** 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 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 Maximum
Twisted Pair Distances section.
3.5.2. Power over Ethernet (PoE)
TPS input and output ports are able to supply other HDBase-T compliant devices over the TPS lines which
are PoE-compliant as well. In this case, the connected transmitter or receiver does not require a local power
supply.
ATTENTION! The Ethernet ports do not support PoE. Only the TPS ports support PoE function.
WARNING! The remote power feature of TPS 95 series extenders is not PoE-compatible. Thus, TPS 95
series cannot be powered remotely by the MMX6x2 matrix switchers (but the video signal is transmitted
to/from the extenders). If a TPS 95 extender is connected to the matrix, make sure that the remote
power jumper of the extender is removed or set to 'Remote power disabled' position.
The PoE feature in the practice
The TPS ports of the matrix are in accordance with IEEE 802.3af (PoE) standard. The feature is demonstrated
on below figure:
Extenders Supplied without Local Power
The concept
Supply the connected extenders through the CATx (TPS) cables without local adapters.
