DIP Switch

The TP 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.

Selecting Communication Protocol

The second switch selects between the available communication protocols, Modbus RTU/ASCII or BACnet MS/TP:

Selecting communication protocol

  • Off: Modbus RTU/ASCII (default);

  • On: BACnet MS/TP.

RS485 Network Termination

The third switch adds or disconnects a termination resistor to the RS485 network:
