You can change the files called 'latest' in:

/MIDAS/experiments/tuda/VMEconfigs

and 

/MIDAS/experiments/tuda/VMEsetups

to change/add ADC, TDC, scaler, etc. modules in the VME crates. Restore these files in the VME MODULES CONFIGURATIONS in MIDAS.

I've attached our configuration files.

See Tom's configuration files as examples:

Shutting Down MIDAS DAQ
-----------------------

The following procedure describes a 'cold' stop of the DAQ.
Normally one would only need to perform steps 1 to 2.

1) If possible, stop data acquisition

   MIDAS Data Acquisition Experiment Control -> select STOP
   
2) If possible, quit data acquisition

   MIDAS Main Menu -> select Quit
   
   From the Quit Session Confirmation pop-up window
   
   select -> Yes
   
3) If possible, stop TapeServer. The TapeServer is normally run from
   a terminal session on tuda2.

   In the command window where the TapeServer was started enter CTRL-C
   
   The TapeServer should respond confirming that its processes have
   received an INT signal.

MIDAS Tape Driver (5615): Received INT signal; exiting.
MIDAS Tape Driver (5614): Received INT signal; exiting.
MIDAS Tape Driver (5613): Received INT signal; exiting.
 
Starting MIDAS DAQ
------------------

The following procedure describes a 'cold' start of the DAQ.
Normally one would only need to perform steps 5 to 9.

1) Login to Sun Blade 100 workstation - tuda2 ISAC-II Experimental Hall

   user: tuda
   password:

2) Switch off the VME crate.
   Wait 20s.
   Switch on the VME crate.
   
   After a short delay (c. 20-30s) you will observe significant network
   load on the Allied Telesys 8-port switch on top of the TUDA 19" racks
   whilst the Lynx operating system is downloaded to the MVME 2431 CPU 
   and the DAQ application is loaded. 
   
3) Open (another) command window on tuda2. Enter the commands

   cd /MIDAS/TapeServer/SunOS
   ./master
   
   This will start the TapeServer process which should conclude with
   messages of the type
   
   MIDAS Data Link (5821): MIDAS Data Link thread 0 using TCP port 10305.
   MIDAS Data Link (5821): Entering server loop
   MIDAS Data Link (5821): thread 0 listening on port 10305

4) Check whether the EPICS access repeater process is running

    tuda2> ps -ef | grep caRepeater
    tuda  2182     1   0 12:35:07 pts/2       0:00 caRepeater

   If the EPICS access repeater is not running, you can start it
   by requesting any EPICS variable, e.g.

   tuda2> caget CCS2ISAC:BL2ACURRENT
   CCS2ISAC:BL2ACURRENT          0

5) Open (another) command window. Enter the command

   MIDAS-session

   From the pop-up window select -> MIDAS Data Acquisition

   If you wish to run a MIDAS session remotely (tuda3 ISAC-II Counting
   Room 1) establish a Secure Shell (ssh) connection from tuda3 to tuda2

   tuda3> ssh tuda2 -l tuda

   and enter the command MIDAS-session in this terminal session.

   It is *strongly* recommended that you do NOT run the MIDAS DAQ
   locally *and* remotely.

6) From the MIDAS Main Menu select Experiment Control ... and wait
   until start sequence is complete

7) From MIDAS Data Acquisition Experiment Control select SETUP.
   From Confirmation Request for Data Acquisition Setup pop-up window
   select Setup Everything
   
   ... and wait until the sequence is complete with the message
   
   MIDAS DA is SETUP and ready to GO at <date/time>

8) From the MIDAS Main Menu select Experiment Control select -> Advanced.
   Select Configuration/Test/Debug Frame. From confirmation pop-up select
   -> Yes - Please Continue
   
   Check the TDC mode is Common Stop, TDC reference is 0, and readout mode is 1.

   Check Data Destination:Tape Server is tuda2daq and select 'Setup Connection'

   Select Update.

   Dismiss the Configuration/Test/Debug Frame.

9) From MIDAS Data Acquisition Experiment Control select Tape Control.

   From the Tape Drive Control window select Allocated? button adjacent
   to /dev/file/0 - No should toggle to Yes.

   Select corresponding Load Tape -> Mount (Append Data to old tape)
   Volume name (S1195) should appear, select Continue.

   If you do not wish to write data to disk (/dev/file/0) select No Storage.

   Dismiss the Tape Drive Control Window.

   From MIDAS Data Acquisition Experiment Control select Redisplay. Tapes
   in use should change to:

   /dev/file/0 (if you are writing to disk)
   Storage is not enabled (if you have selected No Storage)

   Check Histogramming Enabled and TS Transfer Enabled are selected.
   The TS Transfer Enabled button should be green indicating a good
   connection to the Tape Server.

9) From the MIDAS Main Menu select Experiment Control select Go

   If you have selected No Storage you will be reminded of this and asked
   whether you wish to continue, or abort data acquisition start.

Starting data run   
-----------------   
   
Assumes DAQ is already stopped.   
   
1) Clear VME CPU histograms (if required)   
   
   From Spectrum Directory Browser frame select -> Resource -> hist   
   Select -> Select All   
   Select -> Actions -> Zero & Deselect   
   
   The footer of window should show zeroing of spectra in progress.   
   
2) Clear online sort spectra (if required)   
   
   From Spectrum Directory Browser frame select -> Resource -> SortSas   
   Select -> Select All   
   Select -> Actions -> Zero & Deselect   
   
   The footer of window should show zeroing of spectra in progress.   
   
3) Start DAQ   
   
   From MIDAS Data Acquisition Experiment Control select -> GO   
   
   If the DAQ has started OK you should see the 'Good Events' scaler   
   increment and 'Good Events /s' should be non-zero.   
   
4) Complete Elog entry  
  
   The Session Log window will show the start time & date  
   
5) Check run data file

   Open a command window and enter command(s)

   ls -l /net/tuda2/data2/data/S1195; sleep 60; ls -l /net/tuda2/data2/data/S1195

   and check current run data file is increasing in size.

Assumes DAQ is going.  
  
1) Stop DAQ  
     
   From MIDAS Data Acquisition Experiment Control window select -> STOP  
  
2) Save VME CPU histograms  
  
   From Spectrum Directory Browser select -> Actions -> Save  
   The Spectrum Copy & Online Histogram Save window should appear.  
   Select -> Source Resource -> hist  
   Select -> Select All  
   Check destination Directory (e.g. /home/tuda/S1195/spectra)  
   Enter (sub-)Directory (e.g. run100)  
   Select -> Execute  
  
3) Save online sort spectra  
  
   From Spectrum Directory Browser select -> Actions -> Save  
   The Spectrum Copy & Online Histogram Save window should appear.  
   Select -> Source Resource -> SortSas  
   Select -> Select All  
   Check destination Directory (e.g. /home/tuda/S1195/spectra)
