3.6. TPS Interface
The device is built with TPS (Twisted Pair Single) interface which are using HDBaseT
the unit transmits 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.
Both devices TPS mode settings together determine the finally established TPS transmission mode.
The following TPS modes are defined in the transmitter:
▪ Auto: The TPS mode is determined automatically.
HDBaseT: Ideal for high resolution signals up to 4K.
▪
Long reach: Ideal for big distances up to 1080p@60Hz with extended cable lengths.
▪
▪ 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.

** 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
automatically. Long reach mode is not available when both sides are set to Auto mode.
When using automatic operation mode selection, the device determines the mode of operation. If both halfs
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 the
Extension Distances section.

The Concept
Two audio sources are connected to the transmitter: a Blu-ray player on the HDMI input (embedded HDMI
audio); and a Media player on the analog audio input (Jack). The transmitter is connected to a TPS receiver
which transmits the A/V signal to a HDTV.
The following options are available for audio routing / signal selection:
The video input source of the HDTV is the Blu-ray player, you can select from the following audio sources:
– the original embedded HDMI audio from the Blu-ray player;
– the analog audio input from the Media player.
INFO: In case of the TPS-TX220 series transmitters you can use the Autoselect feature for audio input
selection. For the details see
