=== Usage === |

This command sets a "sticky" parameter. It doesn't do anything to the detector, but it sets the exposure type to be performed during the next [wiki:GraspSwControllerCmd expose] command. It only needs to be sent to the controller upon initialization, or when the type changes, though there is no harm sending it before every exposure. |
