h1. DAQ
DAQ is running on simonadaq computer in coda account in the vnc session number 1.
To open VNC, either start VNC from a computer at the counting house through ssh or make a ssh tunnel if you are offsite
Example :
ssh -L5901:locahost:34567 username@hallgw.jlab.org ( use a port number not in used on hallgw )
after from hallgw
ssh -L34567:localhost:5901 cdaq@simonadaq
then open a vnc locally on your computer : vncviewer -shared localhost:1 ( ask Junqi or Sylvester for the vnc password )
To start CODA from scratch, login as coda
type startcoda
that will open the CODA windows
in Run Control GUI, go to platform and connect.
Then choose the FADC configuration and just start a run.
To change the FADC parameters,
ssh to hallcsc-1 as root
go to /root/linuxvme/fadc/rol
and edit fadc_list.c
once done compile with :
make fadc_list.so
and redownload in CODA to take the changes into account
rc
h1. FADC data analysis
on cdaq account
go to /home/cdaq/tlgc/FADC_decode
and run FADCcom program
you need to copy the CODA file from simonadaq to /net/cdaq/cdaql1data/cdaq/tlgc/data ( from simonadaq : scp fadc_runnumber.dat cdaq@cdaql2:tlgc/data/ )
if you open the rootfile you will see the different directories corresponding to the channels decoded.
