== Setting up the analog GS DAQ from scratch ==

from a linux box type

telnet gsts1 2009

That will give you a console window for the analog DAQ system. In here, type
'crtl x' that will reboot the VME processor. After it has rebooted, type

</home/sga2/cur/startup_sga2.cmd
sgainit

Now tha DAQ is ready and you have to specify where it should store your data.
We recommend the following procedure:

Place a USB disk in the the USB docking station on the machine you want to
store your data on. It should automount as something like /media/20140304. To use
the disk it needs to first be exported. Do that as

gsexportfs 20140304

please notice that you should not specify '/media/'

Now log into dgs1 as dgs and

cd /home/sga2/cur/config
cp a cmd file to c1.cmd
edit c1.cmd for your purpose

specify the directory to store the data as something like

datadir gslinux1 /media/abcd/user/tltmp

here is an example of a c1.cmd file that works on the
disk named '/media/20140304' on gslinx1

#------------------------------------
# cmd file created by "savepars" command
# __ on SAT MAY 11 03:04:24 2013
datadir gslinux1 /media/20140304/user/tltmp
# note -- you should specify a new dir if
# you have just rebooted
newexp myexp myexp
# note -- you may want to increment the run number below
newrun myexp 5

setmode -WRITE_ALL_BGO
setmode +RF_TIMING

badcesdump 0

You can use this file as a template if you wish.

You should now be able to start the DAQ and see something like this:

sga2: start
acquisition started
sga2: EB CES switch detected, but there was no overflow flag in CES=1, usi1=0!
1083(8) ev/s; CES 50/50%; no ehi 0.5%; alarm off @ 03/05 12:30
5968(20) ev/s; CES 54/46%; no ehi 0.5%; alarm off @ 03/05 12:30
5740(20) ev/s; CES 49/51%; no ehi 0.5%; alarm off @ 03/05 12:31
5132(18) ev/s; CES 49/51%; no ehi 0.5%; alarm off @ 03/05 12:31

It migh be good to look at the data file as see that it grows as

ls -lt /media/20140304/user/tltmp/myexp

ensuring that you are taking data.

== To stop the DAQ and take your data away ==

On the GAQ console, type

stop
closeall

on the machine where you have mounted your data disk, type

gsunexportfs 20140304

using the datdisk name example from above. This ensures that we
unexport the file so that we can eject the disk using the usinf the
standard linux utility:

locate icon of disk on monitor
click 'safely remove Drive'
confirm that icon coes away
type 'df' to further confirm disk is unmounted

then you can turn your disk off and remove it.

== Online data monitoring ==

cd to directory you want to use. Then get the GSSort packages as

svn checkout https://svn.anl.gov/repos/gs_analysis/GSSort .
or
wget http://www.phy.anl.gov/gammasphere/doc/GSSort/src/src.tgz
tar -zxvf src.tgz

then compile as

make clean
make GSSort

compile GSUtil_cc.so as

rootn.exe
.L GSUtil.cc++
.q

Now create a chat file that looks something like this

#-------------------------------------------
# input
#
;input tape /dev/rmt/1mbn
input net 1101
;input disk greg.data
;input disk data/gsfma68
;input disk /cdrom/cdrom/gsfam137_6.data
;input disk /media/disk/user/data/a1/a1.r001.dat.022
#
#-------------------------------------------
# output
#
;output c1.root
;rootfileoption RECREATE
#
sharedmem c1.map 200000000
startmapaddress 0xab785000
#
#
#-------------------------------------------
# basic sort parameters
#
echo

#

There should be a c1.chat file in the package. If you copy the above line
to a file, make sure you remove the first space in the lines. The lines
starting with # ir ; are comments (not executed).

Now start up roon.exe in a separate window. The first thing to do is to
determine the startmapaddress in the chat file, In this case, type

.L GSUtil_cc.so
sdummyload(200000000)

and enter the start addess reported in the chat file. In the other window, start
GSSort as

./GSSort -chat c1.chat

you should see data come in. Now in the window where you are running rootn.exe,
attach youself to the map file and update

sload("c1.map")
update()

you should now be able to see spectra as

update()
d1("sumehi")

or whatever spectra you want to look at.

==VXI processsor boots==

The VXI processors have dgs6 as their boot host. This is a scientific
linux 6.4 blade computer sitting in the dgs rack. There is a pull out
keyboard and monitor for dgs6 in the rack.

The boot parameters for the vxi processors are documented below

History: The hosting of the vxi processors was originally done by the 'shack' sun computer (which is still alive in the data room), then the hosting was taken over by the 'shack2' Dell linux box (a regular tower). We switched to the dgs6 rackmounted blade machine to save space in the shack.
