Troubleshooting common issues with DAQ
| Issue | Solution/Workaround |
|---|---|
| Warning: EVR state of camera does not match default state. Camera will revert to default after DAQ. | This is not an error. DAQ should not fail if you see this warning. |
| Cannot determine EVR/Trigger state of camera. Aborting | Usually this error occurs when a DAQ fails and the trigger gets stuck on EC 214. Solution: "Fix Cameras" button in GUI OR open the Triggers panels for the cameras you are using. Make sure that only one trigger is selected for each channel. |

Feature requests
| Issue | Person | Priority | Status |
|---|---|---|---|
| Adding UV Vis Spectrometer | Sharon | High | DONE |
| Add no-camera DAQ | Zack | Medium | |
| Add SCP Buff Acq | Zack | Medium | |
| Support 5-10 cameras (E320 request) | |||
| (Maybe) a feature where if a camera goes down, the rest of the DAQ continues without it | |||
Follow up to the request above: Print a "match matrix" at the end that shows matches between cameras instead of just total matches across all cameras (useful if one camera goes down but the rest of the cameras have good matches) | |||
| Add check/remove bad PVs and notify user in an obvious way | Sharon | ||
| Add nonBSA arrays so we can get UV spectrometer (Claudio request) | Sharon | High | DONE |
| DAQ Monitor GUI | Sharon | High | DONE |
| Find a way to globally trigger a modifier bit (e.g. "DUMP_2_9"). | David | ||
| Scan function that pauses until you click 'ok' | |||
| Generate "camera config" file including trigger info and add a save/restore button. Monitor if this finished ok or not. | Sharon | ||
| Load/Save Config files. Default config files. | Claire | ||
| Robustness issues. . . | Spencer | High | In progress |
| DAN features | Sharon | ||

Documentation
For now, the main references on the DAQ are these attached PDFs from IBIC 2021.
GUI Interface
Main screen → Profile Monitor → LI20 → FACET DAQ (green button)
Wait for a bit after pressing the FACET DAQ button.
DAQ Camera Status GUI
Main screen → Profile Monitor → LI20 → DAQ Camera Status
