Applied firmware package: v1.4.0 | LDC software: v2.4.0b3
4.1.
Overview
HDMI-TPS-RX220AK is a multifunctional TPS receiver with audio de-embedding function and USB KVM
feature. The device receives audio/video, Ethernet, RS-232 and Infrared signals via the TPS input port and
can be powered by another extender due to the PoE-capability. The receiver can be controlled via USB,
Ethernet, RS-232 or Infrared and is able to control third-party devices via the RS-232, Ethernet, Infrared and
USB KVM.

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.
Both devices TPS mode settings together determine the finally established TPS transmission mode.
The following TPS modes are defined in the receiver:
▪
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
4.3.

The device can receive two HDMI or DVI signals up to 4K30 (4096x2160@30Hz) resolution. The streams can
be routed to any HDMI output ports over the 2x2 digital video crosspoint. The HDMI outputs can transmit
HDMI or DVI signals up to 4K UHD 30 Hz (3840x2160@30Hz) resolution.
