No parity
In normal serial communications, data is configured in single bytes, and messages are created by
stringing together multiple bytes of data. The parity check described here sets the check for each byte of
data. Set the parity check method that is required by the Master.
Note
The entire message is checked by a separate check code called “CRC-16,” so the communica-
tions data will be checked even if no special parity check is performed.

Set this parameter to an awaiting period for returning a response after the DSR (data-send-request)
message is received from the Master.
