• Sign
Select whether or not to add a sign to the data.
The selectable range for the data reference value varies depending on this setting.
• MSB/LSB
Set the MSB and LSB positions in the data to compare. For example, to compare
bits 5 to 20 in a 4-byte data stream (12345678 in hexadecimal notation), set the
MSB to 20 and the LSB to 5. The shaded sections in the following figure indicate
the bits that will be compared depending on the byte order setting.
Selectable range: 0 to the data size bytes × 8 – 1. The maximum value is 63.

• ACK
You can use the ACK slot status as a trigger condition. The ACK trigger condition is
met when the selected status matches the input signal ACK slot status.
Don’t care
Not used as a trigger condition
NON ACK
When the status is recessive
ACK
When the status is dominant
NON ACK or ACK
When the status is recessive or dominant
ID/Data OR Mode
The DL9000 triggers on the OR logic of multiple ID Std/Data conditions or multiple ID
Ext/Data conditions. You can set up to four ID Data conditions. The ID Std/Data settings
are shared with the ID Ext/Data settings.
• You can select whether or not to use each ID/Data condition as a trigger condition.
• The trigger conditions and settings of each ID/Data condition are the same as those
described on pages 6-61 to 6-63. See the respective page for details.
Note
When using the ID/Data OR mode, set conditions so that the trigger point will be the same. If
you don’t, the DL9000 may not trigger at the correct position.
