Remote - Only Frame ID Setup fields are enabled.
Data - Both Frame ID and Data Pattern ID Setup fields are enabled.
Error - Triggers only when an error signal occurs. No Frame ID and Data Pattern ID Setup
fields are enabled.
4. Setup Format
Select either Binary or Hexadecimal (Hex) setup mode. The mode selected propagates
through the entire CANbus trigger setup.
Try selecting Binary mode, and set up the Frame ID in binary format, then re-select HEX
mode and set up the data in hexadecimal format. Toggling back and forth between the
modes does not result in loss of information.
5. Frame ID Setup
Frame ID Setup is used to trigger on a specific Frame ID value with either 11 or 29 Bits.
When CANbus trigger selections are either Remote or Data, use the Frame ID Setup fields
as follows:
ID Condition - The ID condition can be set to many different values. If the ID condition is
set to “=”, then a data definition can also be set. Any other ID condition precludes setting
up a Data condition.
The ID condition can be set to <=, <, =, >, >=, not =, in a range, out of a range, or don’t
care.
ID Bits - The trigger can be set to trigger on CAN messages with either 11-bits (Standard
CAN) or 29-bits (Extended CAN). You can also set the trigger so that it triggers on a
message that meets a condition for either the 11-bit or 29-bit ID. For instance, there
might be an 11-bit ID value that is present in both an 11-bit and a 29-bit ID, and by
choosing ALL, you could trigger when that ID is present on either of those messages.
Frame ID - Specify the desired frame ID for triggering here.
