3. Product Overview
3.8.3. 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.

Disconnect
This mode is for control the third-party device from the Matrix. In this case, the Matrix does not receive
RS-232 messages but sends serial data from the CPU.

The concept
Powering on the HDTV via RS-232 message from the matrix.
Settings
The Matrix can send RS-232 commands over the local RS-232 ports (P1 or P2) to the HDTV. You can see the
details about serial message sending in the
Control mode
The incoming data from the given port is processed and interpreted by the CPU. The mode allows to control
the matrix directly. LW2 or LW3 protocol commands are accepted – depending on the current port setting.
