The following table defines each value of type:

Value

Definition

EVEN

If

PARity:CHECK is ON, the received parity bit

must maintain even parity. The transmitted parity
bit will maintain even parity.

ODD

If

PARity:CHECK is ON, the received parity bit

must maintain odd parity. The transmitted parity
bit will maintain odd parity.

ZERO

If

PARity:CHECK is ON, the received parity bit

must be a zero. The transmitted parity bit will be a
zero.

ONE

If

PARity:CHECK is ON, the received parity bit

must be a logic one. The transmitted parity bit will
be a logic one.

NONE

A parity bit must not be received in the serial data
frame. No parity bit will be transmitted.

While this command operates independently of either the

BITS or

SBITs commands, there are two combinations which are disallowed

because of their data frame bit width. The following table shows the
possible combinations:

Received parity will not be checked unless

PAR:CHEC ON is has been

sent. Transmitted data will include the specified parity whether

PAR:CHEC is ON or OFF.

DIAG:BOOT:COLD will set

PARity to NONE.

Related Commands:

SER[n]:SBITs 1 | 2

*RST Condition: No change

Example

Set parity check/generation to ODD.

SYST:COMM:SER0:PAR ODD

Set parity type

SYST:COMM:SER0:PAR:CHEC ON

Enable parity check/gen.
