3. Product Overview
3.10.2. IR Interface
ATTENTION! For the complete usage attach an IR emitter unit to the IR OUT and an IR detector unit to the
IR IN connectors.
Technical Background
The Infrared signal transmission is similar to the serial data communication. The transmitter contains
dedicated IR I/O connection and also can transmit/receive IR signal via the TPS interface. The signal is in
pronto HEX format in both cases.

Block diagram of the IR interface
The most trivial usage of the IR interface is the transparent mode: signal received or sent on local IR ports
are transmitted directly on the TPS IR link port and vica versa. Beside of this there is an IR recognizer in the
device where you can assign actions in Event Manager for. The third option is the command injection mode
(like at serial interface in the previous section) where you can send IR commands over LAN. Command
injection mode can be turned on and off by input/output ports.
INFO: All settings are available in the LDC software, see settings in the
INFO: The modulation of output IR signal can be turned off or on by LW3 command, see details in the

The Concept
An IR detector is attached to the Infrared input port of the TPS receiver and IR signals are sent by the Remote
controller. The TPS Receiver is connected to a HDMI-TPS-TX200 series transmitter built with IR output port
via TPS line.
Settings:
Set the TPS IR link of the Transmitter to Transparent mode. IR signals are received over the local IR input port
of the Receiver by the Remote controller. The signals transmitted further over the TPS line to the Transmitter
which can control the Blu-ray player via an IR emitter.
3.10.3. Ethernet Control Interface
The device can be controlled over front panel Ethernet standard RJ45 connector which connected to LAN.
This interface supports both LW2 and LW3 protocols.
The interface can be used to remote control the device with Lightware Device Controller and establish the
connection to Lightware Device Updater software and perform firmware upgrade.
