6.7. Infrared Interface
This section is about the Infrared interface of the endpoint device.
DIFFERENCE:
Only the UBEX-PRO20-HDMI-F110 model has built with IR interface ports.

ATTENTION! The device has no built-in Infrared receiver and transmitter. For the complete usage attach
the supplied IR emitter unit to the IR OUT and the IR detector unit to the IR IN connectors.
6.7.1. Technical Background
Port Diagram
Port diagram of the Infrared interface for the UBEX matrix
The Concept
The endpoint device uses command injection which means in the practice it works as a TCP/IP -> Infrared converter
so the TCP/IP data signal is converted to Infrared code. The IR message is sent over the Ethernet interface.
A TCP port in the MMU addresses an Infrared output port in the endpoint device. The user can set which TCP
port is ordered to the required Infrared output port.

INFO: It does not matter which device of the Ethernet interface (the MMU directly or any endpoints) you
want to use establishing connection with the UBEX matrix, you will reach the MMU finally.

Setting up the TCP Ports of the IR Interface
The default starting port number is 9000 and increases with one until the number of the IR ports in the
matrix. If these TCP ports are reserved in the network, the port numbers can be changed in LDC (see the
details in the Infra Tab
Communication Ports
6.7.2. Infrared Signal Transmission – Example
The Concept
The devices which have built-in IR detector (4K TV, audio amplifier) are controlled with Infrared messages
which are sent over Ethernet interface. All Ethernet devices can send messages to all controlled devices. Up
to three Ethernet devices can be connected per endpoints.
You can send IR messages using two methods:
▪ Lightware Device Controller (LDC) / Built-in Website - see the details in the
▪ LW3 protocol commands - see the details in the
section) or using LW3 protocol command (see the details in the
section).
