5. Device Concept
IR Interface - Example
The Concept
IR command ('Power on') can be sent from the smart phone with IR - TCP/IP converter application over
WI-FI. The TCP/IP message is forwarded to the matrix via Control Ethernet port. The Matrix converts the TCP
message to IR format and transmits the IR signal to the IR output port (e.g. 9001). The connected IR emitter
sends the IR command ('Power on') to the TV.
Settings
Matrix: Control Ethernet port (P2) can be enabled. Check the IR port number (default value is 9001). The
port can be enabled (operation mode is always command injection).

5.7. Serial Interface
Technical Background
Serial data communication can be established via the local RS-232 port (Phoenix connector), TTL serial port
(Phoenix connector) and over the TPS lines. The RS-232 ports – which are connected to the microcontroller
– can be configured separately.
INFO: The 2-pole Phoenix connector can both infra and serial output depending on the sent message
protocol. No setting required for configuring the interface, it works automatically.
