RS-232 INTERFACE 7 - 9
Parity
A parity check bit is the most significant bit of each ASCII coded character. Select the parity type according to
host device requirements.
•
Select Odd parity and the parity bit value is set to 0 or 1, based on data, to ensure that an odd number of
1 bits are contained in the coded character.
•
Select Even parity and the parity bit value is set to 0 or 1, based on data, to ensure that an even number
of 1 bits are contained in the coded character.
•
Select None when no parity bit is required.
Stop Bit Select
The stop bit(s) at the end of each transmitted character marks the end of transmission of one character and
prepares the receiving device for the next character in the serial data stream. The number of stop bits selected
(one or two) depends on the number the receiving terminal is programmed to accommodate. Set the number of
stop bits to match host device requirements.
