even parity bit

Bit 8 is the even parity bit of bits 0-7.

An even parity bit follows, then a stop bit at 1200 Hz.

In the 26-bit Wiegand format, bit 1 is an even parity bit.

In serial data transmission, a common format is 7 data bit, an even parity bit, and one or two stop bits.

There are two variants of parity bits: even parity bit and odd parity bit.

As specified by the SDI-12 Support Group, all SDI-12 communications are transmitted in ASCII at 1200 baud with 7 data bits and an even parity bit.

Each data frame consists of a start bit of 1, an 8-bit data field, a 3-bit station address, and an even parity bit (which includes the start bit, so it equivalent to odd parity over the data and address fields only).
