Parameter 3 for RS-485: Sensor control and communication protocol
This parameter performs two functions
Left digit: Sensor control
0-> Disable sensor information
1 -> Enable sensor information
Right digit: Communication protocol,
The user can select between the following protocols:
0: ASCII: Really simple protocol that uses ASCII characters
1: ModBus RTU-ASCII: This uses the ModBus protocol, but the temperature and
humidity data are coded in ASCII in the same block.
2: ModBus RTU-Word. This uses the ModBus RTU-Word protocol. The
temperature and the humidity are independent words.
In the display that receives the data through serial line (DC-25), the sensor information must be
disabled.
