Log in as apar@adaq1
In a terminal type startcoda
- 4 xterms will appear (red, orange, green and yellow) as well as the main CODA window (see Figure 1)
- CODA will automatically load the last configuration used. If you are ok with this then just go to Platform->Connect
To change the configuration, choose Configurations->Cool
- Select the desired configuration from the dropdown list (see Figure 2)
- Production running would be ALL_PREX
- Once you have loaded a configuration, some of the icons (see descriptions below) will change from grey to green
Press the configure icon
- Warnings about waiting for a roc can be ignored if it does not take too long to respond (~10s) and things are eventually successful
- Error messages should be taken seriously
  - You can try a reset and reconfigure
  - If that doesn't work - see DAQ Troubleshooting
Press the download icon

After starting the GUI and loading a configuration (see above)
Press the Prestart icon
- a window will pop up where you can add notes if necessary (not yet implemented for PREX)
- submit or save the notes
- Warnings about waiting for a roc can be ignored if it does not take too long to respond (~10s) and things are eventually successful
- Error messages should be taken seriously!
  - You can try a reset and reconfigure
  - If that doesn't work - see DAQ Troubleshooting
Press Go
- the event counter should start incrementing
- the event rates should be expected values

Press the End icon
- if this was a normal end of the run, and it ends successfully
  - all the states should change to downloaded
  - the prestart icon should be green
If the run ends because of a problem with CODA - see DAQ Troubleshooting

Either the Event Builder (EB1) or Event Recorder (ER1) are disconnected
- kcoda
- startcoda (follow instructions for starting CODA)
If a ROC is disconnected
1. try to reset; if successful you should get Client is back message and everything should report Configured
2. if a ROC is still reporting a problem - note which ROC is reporting the problem
  1. if the console for that ROC is responding type reboot and enter
  2. otherwise, use the remote power cycle to reboot that ROC (link to be added later)

Numbered from the top left of the GUI window (see any of the Figures):

Configure (tools) - this opens a drop-down menu to choose the configuration
Download (floppy disk) - this loads the chosen configuration to the crates
Prestart () - this will prepare to start a run
Go (triangle with point to right) - this starts a run
End (square) - this ends a run
Fast Start (double-triangle pointing right) tries to go through all the steps (can be used as long as things aren't changing)
Reset (double-triangle pointing left) configured, but not downloaded (if you need to change configuration or GUI is wonky)
Pause (two vertical bars) - pauses a run (rarely used - to quote Paul Nothing good comes of this.)
