An updated copy of the merger has been downloaded ( merger64.AD ) with a copy of /MIDAS/Merger/AIDA/Startup.

These two enable the output of all of the SYNC data items to the TapeServer.

The System Wide Checks browser window has been updated and includes a report of the number SYNC pulses sent by the Master timestamp module and the number of SYNC pulses received by the Slave modules. These should all be the same value.

The ASIC4 browser window has been updated to add two actions to the Experts only menu. "Disable all ASICs For Readout"  and "Enable all ASICs for Readout". These two are useful when starting a noisy system. The sequence would be to start the Merger, toggle Pause. Then start the DAQ ( FEE64s ). "Disable all ASICs For Readout" then in the Merger toggle Pause. I found this made starting the merging much more successful. Then "Enable all ASICs for Readout" to run. I shall add similar actions to the Discriminators but will ensure the Mask Patterns set by the Restore are maintained and restored by the "Enable" action.

Before adding this capability it was quite hard to tune the system to guarantee the Merger a full set of SYNC data items at any one time. I have been running the FEE64s with low thresholds, detectors and no HV.
