NDOS Shifter Instructions

Starting the Trigger

The following steps show how to start the trigger processes on the buffer nodes. As long as the buffer nodes are up, you can execute these instructions, but it is usually done after the run is started.

1. Click on the "DDT Manager" icon on the same display as NDOS Run Control:

2. The following manager screen should pop up (you might have to scroll around the display to find it):

3. Click the "Start Group" button to start all of the processes and when they are all running it should look like this:

*Note that the data-driven triggers record shorter time windows, so you will see very clean events in the Event Display.

Stopping the Trigger

1. Click the "Stop Group" button and wait until everything is pink (not running).

2. Click on File -> Exit to exit the manager:

Recovering a Trigger

Occasionally a trigger process might die, so you can recover it as follows:

1. Send an email to telling us which trigger process died. For example, trigger process 002 died here:

2. Right-click on the dead process and click "Start Process":

3. Everything should be green again.

4. If the process dies more than twice in an hour, do not restart it again, but notify us via email.
