"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 beginning of the
data pattern. For "Little Endian" transfer direction, the exact number of
data bytes in the frame must be set.
Example: Data length ≥ 2 and Transfer = Big endian. The frame has at
least two bytes, and you trigger on the data of the first two bytes.
"Condition"
Sets the operator to set 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. The data is compared byte by
byte.
In binary format, use the following characters: 1; 0; or X (don't 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 slave identifier ("Frame ID"), the number of data bytes
("Data length"), and select "LIN standard". See also: "LIN standard" on page 299.
●
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
