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 Mark parity and the parity bit is always 1.
• Select Space parity and the parity bit is always 0.
• Select None when no parity bit is required.
