DIP Switch

The Touch Point panel is equipped with a 3-position DIP switch. Each of three sections has a separate function:

  • the first switch allows for restoring default settings;

  • the second switch allows for selecting a communication protocol;

  • and the third switch allows for the RS485 network termination.
