CHAPTER 13 RS-485 COMMUNICATIONS

Set existence and logic of a parity and a stop bit length.

Characters are organized for each setting as follows:

LSB

Parity Stop

2 Start

Data (8 bits)

Stop

3, 4 Start

Data (8 bits)

Parity Stop (2 bits)

5 Start

(*) Actual response time is set to PA2_94 setting or {time for 3 characters + amplifier’s processing time},

whichever is longer.

Set the response time and communication time over parameters if needed.

For details, refer to pages 13-34 (response time) and 13-35 (communication time over).
