TPS Receiver Concept
HDMI-TPS-RX110AY is a multifunctional receiver with HDBaseT
TM
(TPS) technology. The device can be
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.

processed in the HDBaseT
TM
receiver unit. The audio de-embedder separates the digital audio and video
signals. The digital video signal through the HDMI re-clocker can be forwarded to the local sink device by the

forwarded to the local audio sink device by the analog audio output port.

TPS Interface
The device is built with TPS (Twisted Pair Single) interface which are using HDBaseT
TM
technology. It means
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.

and the auto-mode device follows through. The allowed cable lengths and resolutions are listed in the
