System control via extended Ethernet (example)
Current setup allows the following:
▪ The
System controller
can communicate with LW2/LW3 commands to the IP:port address of the
Matrix
or the
Extender.
3.8.1. IR Interface
Technical background
The Infrared signal transmission is similar to the serial data communication. However the matrix does not
contain dedicated IR I/O connection, the TPS interface can transmit/receive IR signal in pronto HEX format.

2 IR output
of the TPS port.
When the data transmission is enabled, the input/output port works in Command injection mode. The IR data
(in pronto HEX format) is transferred between the TPS port and the LAN port. Separate user-configurable
TCP/IP port numbers are defined for TPS IR input and IR output ports for this purpose, see
Factory Default
Settings section. The settings are available in the LDC software, see Infra Tab section.
ATTENTION! The IR signal cannot be routed from an IR port to another IR port.

IR signal transmission – example
IR Signal Transmission
The concept
When a certain button is pressed on the remote controller, the crosspoint is changed in the matrix. The IR
code is sent through the TPS cable and recognized by the matrix. The recognized code is a condition which
triggers the action (crosspoint change).
Settings
Matrix:
The matrix has to learn the IR code in advance to recognize it, see Infra Tab section. Then create a new
event, where the stored IR (hash) code is the condition, see Create or Modify an Event section. The action is
the desired crosspoint setting.
