    ------ Ind 03: RS-232 Example --------

    Explanation: Basic example that turns on, reads and turns off the
    modbus sensor. To read a modbus sensor over RS485 connect it to

  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor are:
  - XTR_SOCKET_F       _________
                      |---------|
                      | A  B  C |
                      |_D__E__F_|


  Example: Modbus sensor on socket E over RS232 will be
  [Sensor Class]    [Sensor Name] [Communication speed]
  Industry232       mySensor      (baudrate);
  
  Refer to the technical guide for information about possible combinations.
