7.0. RS-485 Communication Module
7.0. RS-485 Communication Module
The RS-485 communication is a communication standard primarily intended for the use in industrial applications. The main
features of this communication standard is the ability to exchange data between distant points (up to 1200 m) and high tolerance
to accompanying noise. The PICPLC16 v6 development system features a connector which enables devices using RS-485
communication to be linked. The ADM485 circuit acts as a transciever between an external device and the microcontroller. To
enable connection between the microcontroller and the RS-485 communication module, it is necessary to set switches 1, 2 and 3
on the DIP switch SW9 to the ON position.
