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 Maximum Extension Distances section.
