Example with set point transfer of 30.5 °C to the constant temperature

equipment.

"OK"CRLF

Example

The interface operates with 1 stop bit, 8 data bits and no parity bits.

4 transmission speeds are available for selection: 2400, 4800, 9600 or

19200 baud. 9600 baud is the factory preset.

RS 485 commands are always preceded by the device address; up

to 128 device addresses are available. Device addresses always contain

three digits and start with "A": "A000_..." – "A127_...".

Commands from an external source must always end with CR. The

response from the constant temperature equipment always ends with

CR.

Example with set point transfer of 30.5 °C to the constant temperature

equipment. In this example, the address 15 is used.
