For RS485 wiring connections between the controllers and the Server PC, the Daisy Chain connection topology is the recommended wiring connection.
The address of the controller must be unique (ranging from '00' to '15'), I.e. no two controllers in the same RS485 connection network can have the same address.
Each RS485 network bus can support up to a maximum of 16 controllers.
