4.1. TPS Receiver Concept
HDMI-TPS-RX110AY is a multifunctional receiver with HDBaseT
controlled via many kind of interfaces, e.g. Ethernet, USB, RS-232, and Infrared. The receiver is built with
audio de-embedder and relay function.

4.3. TPS Interface
The device is built with TPS (Twisted Pair Single) interface which are using HDBaseT
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.

** 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
