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.
Figure 4-1. Summary of the interfaces
4.1. TPS interface
4.1.1. 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:
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 section 10.5 on page 115.
