Run procedures

start DAQ

There are 3 controls associated with Run Control on the main page of either GUI

• Start/Stop - this is self explanatory. Pushing to start begins taking data.
• NoSave/Save - If set to Save, IOC buffers fill with data. You must attach a receiver to each digitizer IOC or the system may crash horribly once the buffers fill up.
• Copy/Sort - In Sort mode, the data out of the IOC is time ordered according to the time stamp. You should always be in the Sort mode

To start the DGS and DFMA systems you usually do the following:

• on the DGS side, find the window where the DGS data is stored. There will be a start.sh script there. Start the receivers up by typing

 start.sh <runNo>

where <runNo> is the run number you want. A bunch of windows should show up, one for each receiver/IOC pair

• On the DFMA side, find the where the DFMA data is stored. There will be a start.sh script there. Start the receivers up by typing

 start.sh <runNo>

where <runNo> is the run number you want, the same as what you used on the DGS side please. A bunch of windows should show up, one for each receiver/IOC pair now in the FMA setup

• If necessary, synch the clocks of the two systems by clicking on the empirative sync button on the DGS side. Please don't click on the empirative sync button on the DFMA side

• now, as simultaneous as you can, click the start buttons on the DGS and DFMA DAQ windows. You should see the receivers on both systems receiving data.

• may want to check that the data files are growing to be sure data is coming in

stop DAQ

stop run on both sides : click on stop in the commander windows and then stop the receivers : type Ctrl C on all the receivers (IOC1, OIC2 ....)

syncing two systems

For DGS

• Goto trig0 window.
• Turn off SYNC U - listed under LRU Control
• Make sure receive/send power is on for L & U

Note: If SYNC U is turned off - an Impeartive sync by DGS will reset the master clock on DFMA.

For DFMA

• Goto Trig0 Window
• Under Misc Control - turn on both undefined buttons
• Pull up diagnotsitc window on trig0.
• Set Clrk Source to LINK
• Set Nim1 and Nim2 out on master trigger module FMA

Note: Clock Source cannot be set to LINK in GUI. Set address 0x8D0 in slot 0 to set 1 for trigger modules. This needs to be fixed in Driver by Tim.
