Examples
TRIGGER:A:BUS:B1:CAN:DATA:DIRECTION WRITE
sets the CAN data
direction to Write.
TRIGGER:A:BUS:B1:CAN:DATA:DIRECTION?
might return
:TRIGGER:A:BUS:B1:CAN:DATA:DIRECTION NOCARE
indicating the data
direction can be either read or write.
TRIGger:{A|B}:BUS:B<x>:CAN:DATa:OFFSet
This command sets or queries the data offset value, in bytes, to use when
triggering on the CAN data
fi eld. The bus number is speci fi ed by x. The trigger
condition must be set to DATA or IDANDDATA.
Conditions Requires the SR-AERO Triggering and Analysis application.

Arguments
<NR1>
is an integer whose minimum and default values are -1 (don't care), and the
maximum is up to 7 (for CAN 2.0) or up to 63 (for ISO CAN FD and Non-ISO
CAN FD).
The maximum is dependent on the number of bytes being matched and the CAN
standard selected. Its value is calculated as [Absolute Maximum] - [Data Match
Size]. For CAN 2.0, the absolute maximum is 8 bytes. For ISO CAN FD and
Non-ISO CAN FD, the absolute maximum is 64 bytes. The minimum data match
size is 1 byte, which produces the ranges listed above. Increasing the data match
size above 1 byte will adjust the range of valid data offset values accordingly.
Examples
TRIGGER:A:BUS:B1:CAN:DATA:OFFSET 5
sets the CAN data offset to 5 bytes.
TRIGGER:A:BUS:B1:CAN:DATA:OFFSET?
might return 7, indicating the CAN
data offset is 7 bytes.
If the CAN standard is set for CAN 2.0, and the trigger data size is set to 3, the
maximum value for the data offset will be 5 (8 - 3 = 5).
