When using the Message Capture method for Standalone Logging within VehicleScape DAQ, the choice of Start Option determines the Stop Option choices that appear. Table 1 summarizes the three options, shows the Start Options that each is associated with, and contains links to detailed help pages for all three.
Table 1: Stop Options for the Message Capture Method
| Stop Option | Description | Associated Start Options |

Stop logging after a certain number of messages are logged, or when an expression evaluates as true. | Start immediately |
| Pre/Post Collection | Log data before and after the Collection Start trigger. The capture window can be defined using an expression, a length of time, or a number of messages. | Start using trigger expression |
| One-shot Report | Log a snapshot of data values after waiting a configurable amount of time after the Collection Start trigger. | Start using trigger expression |
Note: The One-shot Report stop option is also used by the Bus Query method.
