> It has been observed that when starting the AIDA data acquisition (select 'GO' from the 'Data Acquisition Run > Control' window) that from time to time one, or possibly more, FEE64 modules fail to begin producing data. > Once running they appear to be totally reliable. > > The result is that these FEE64 modules produce no AIDA SYNC data items or ASIC Events - they may still > produce WAVE SYNC and Wave Events. > > The best check to make after starting the AIDA data acquisition is to select 'Data Acquisition Statistics' > from the 'Data Acquisition Run Control' window. In the 'Data Acquisition Statistics' window check that > 'Show ALL Data Acquisition Servers?' is selected. From the 'Select counter to monitor' menu select > 'AIDA SYNC' and select 'Update Once' to update the counters and rates. > > Check that all FEE64 modules show a rate of ~1500/s. > > If you see 0 then that module has failed to start. > > The recommended procedure is: > > 1) Make a note of the FEE64 module which is not producing AIDA SYNCs. > > 2) Go to the 'Merge Control' window and select 'Reload'. > > The status banner should show > 'Merge State = GOing : merging : xfer enabled : waiting for SYNC' > > Select 'Toggle Merge Program Pause State'. The status banner should show > 'Merge State = GOing : paused : xfer enabled : waiting for SYNC' > > In this state the Merge software will read data from all links but discard the data and make no attempt > to time align the data streams which is impossible if one, or more, streams is not producing AIDA SYNC > data items. > > 3) Return to the 'Data Acquisition Run Control' window > Deselect 'Act on ALL Data Acquisition Servers?' > Select the FEE64 module which is not producing AIDA SYNC data items from the 'Acquisition Servers' menu. > From the 'System functions (Only use if you know what they do!!!)' menu select 'Go Electronics'. > > This will reset and restart the electronics for this FEE64 module without changing any setting. > > If you now check the 'Run Control Data Acquisition Statistics' window, hopefully you will see > that the FEE64 module is now producing AIDA SYNC data items. > > 4) If so, return to the Merge Control window. > Select 'Toggle Merge Program Pause State' and the status should change from 'paused' to 'merging'. > After a few second you will hopefully observe the Merge software begin to time align the data streams > and start producing a merged, time-ordered data stream.
