Parity
Defines the optional parity bit that is used for error detection.
"None"
No parity bit is used.
"Even"
The parity bit is set to "1" if the number of data bits set to "1" is odd.
Adding the parity bit makes the data word's parity even.
"Odd"
The parity bit is set to "1" if the number of data bits set to "1" is even.
Adding the parity bit makes the data word's parity odd.
Remote command:
BUS<b>:UART:PARity on page 396
Stop Bits
Sets the number of stop bits: 1 or 1.5 or 2 stop bits are possible.
Remote command:
BUS<b>:UART:SBIT on page 397
Bit Rate
Sets the number of transmitted bits per second.
"Predefined"
Selects from a list of predefined bit rates between 300 Bit/s and
1 MBit/s.
"User"
Specifies an individual bit rate with values between 150 and
39,062,500.
Remote command:
BUS<b>:UART:BAUDrate on page 397
Data Size
Sets the number of data bits of a word in a range from 5 to 9 bits.
Remote command:
BUS<b>:UART:SSIZe on page 396
Idle Time
Sets the minimal time between two data frames (packets), that is, between the last
stop bit and the start bit of the next frame.
Remote command:
BUS<b>:UART:BITime on page 397
12.4.3 UART Trigger
Before you set up the trigger, make sure that the bus is configured correctly. See
Chapter 12.4.2, "UART Configuration", on page 189.
