DAQ¶

Starting CODA
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:portnumber username@hallgw.jlab.org     ( use a port number not in used on hallgw and there are some limitation on the port range I think between 10000 and 30000 should be ok)

after from hallgw

ssh -Lportnumber: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

If the ROC is not started alread, ssh root@hallcsc-1 and type ./startroc1

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

I saw from time to time error in FADC ROC window about scanmask, usually stopping the run and redownloading fixes the issue.

Powercycling the crate ¶

telnet  129.57.168.242 2003

type CAEN

and a menu should appear

C.A.E.N.  A8160 VME8100 Crate Controller    V1.05

B O A R D   M E N U

Crate           PS & Fan Status   
     General         General Status    
     Update          PS Firmware Update

Quit            Abandon program

Type C

and then you will see fan status and you can turn the crate on or off with O

Channel Map¶

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.
