"Data length"
Sets the length of the bit pattern to be found, in bytes.
For Big Endian transfer direction, you can trigger on a number of
bytes less than the data length of the frame, that means, on the first
bytes that are transmitted. For Little Endian transfer direction, the
exact number of data bytes in the frame must be set.
Example: The data word to be sent is 12 34 56, and it is sent little
endian by the LIN node. With Data length ≥ 2 and Transfer = Big
endian, you trigger on the data of the first two bytes, that is 56 34.
With Data length = 3 and Transfer = Little endian, you trigger on the
required data word 12 34 56.
"Condition"
Sets the operator to define a specific data pattern ("Equal" or "Not
equal") or an data range.
"Data min"
Defines the data pattern. The pattern length is adjusted to the data
length setting (and vice versa), maximum is 8 bytes.
Enter the pattern MSB first and with big endian byte order, and set
the correct "Transfer" direction. The data is compared byte by byte.
In binary format, use the following characters: 1; 0; or X (do not care).
The use of X is restricted to the operators "Equal" and "Not equal".
"Data max"
The second data pattern is required to specify a range with conditions
"In range" and "Out of range".

Error conditions
Triggers if one or more of the following errors occur:
●
Checksum error
The checksum verifies the correct data transmission. It is the last byte of the frame
response. The checksum includes not only the data but also the protected identifier
(PID). To identify checksum errors caused by data, additional settings are required:
Enter the bit pattern of the identifier ("Frame ID"), the number of data bytes ("Data
length"), and select the used "LIN standard".
See also: LIN standard.
●
Identifier parity error
Parity bits are the bits 6 and 7 of the identifier. They verify the correct transmission
of the identifier.
●
Sync error
Synchronization error
