## Enumeration Members

### even

• **even** = ``"even"``

'even' (Even Parity)
The parity bit is set so the total number of 1 bits (data + parity) is even.
Example:
 Data 10110010 has 5 ones (odd).
 Add parity = 1 → total 6 (even).
 More robust than 'none' because it catches single-bit errors.

Very common in industrial Modbus RTU (often 8E1).

#### Defined in

src/WDX/Schema/Model/Instance/DataAdapter/MODBUSRTUParity.ts:46

___

### mark

• **mark** = ``"mark"``

'mark' (Mark Parity)
The parity bit is always 1, regardless of data.
Does not provide error detection, but enforces a “high” line level at parity time.
Rare; sometimes used for compatibility with legacy teletypes or old serial gear.

#### Defined in

src/WDX/Schema/Model/Instance/DataAdapter/MODBUSRTUParity.ts:54

___

### none

• **none** = ``"none"``

'none' (No Parity)

No parity bit is added. Each frame is just start + data bits + stop bits.
Fastest, but no error detection at the byte level (only CRC at Modbus level).
Often called 8N1 → 8 data bits, None parity, 1 stop bit.
Common with modern Modbus devices that rely solely on CRC.

#### Defined in

src/WDX/Schema/Model/Instance/DataAdapter/MODBUSRTUParity.ts:34

___

### odd

• **odd** = ``"odd"``

'odd' (Odd Parity)
The parity bit is set so the total number of 1 bits is odd.
Example:
     Data 10110010 has 5 ones (odd).
     Add parity = 0 → still 5 (odd).
     Same error-detection strength as 'even'.
 Less common, but some older devices insist on 8O1.

#### Defined in

src/WDX/Schema/Model/Instance/DataAdapter/MODBUSRTUParity.ts:65

___

### space

• **space** = ``"space"``

'space' (Space Parity)

The parity bit is always 0, regardless of data.
Same as 'mark' in that it doesn’t check errors, just forces a “low” line level.
Also rare; only seen in very old/quirky devices.
