- How to adjust the parity bit parameters?
Resolution / Answer
This setting is used to configure the communication method or communication parameters between the device and the host. Usually when connecting to a computer, serial device, RS485/Modbus network or access control Wiegand system, you need to ensure that the parameters at both ends are consistent.
A parity bit is the most important bit of each ASCII code character, and the parity type is selected according to the host requirements. If odd parity is selected, the parity bit has a value of 0 or 1, depending on the data, to ensure that the 1-bit odd bit is included in the code character.
odd number
Scan the following barcode, odd numbers.
If even parity is selected, the parity bit has a value of 0 or 1, depending on the data, to ensure that an even number of 1 bits is included in the code character.
Even number
Scan the following barcode, even number.
The MARK parity bit is selected and the parity bit is always 1.
Tags
Please scan the corresponding barcode tag below.
SPACE parity is selected and the parity bit is always 0.
Space
Scan the following barcode to configure space.
If parity is not required, select None.
None
Scan the following barcode, None.
