 h1. DAQ 


 h2. 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. 

 h2. 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

 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.

 h2. Access HV crate. 
 *The HV crate can be remotely accessed through the port server port 2002 to access the port: telnet    129.57.168.242 2002 
 *To end a telnet session type:"CTRL-]" then quit 
 *If someone else is connected to the 2002 if you get : 
 <pre> 
    Trying 129.57.168.242... 
 telnet: connect to address 129.57.168.242: Connection refused 
 </pre> 

 *To force a connect you must first kill the 2002 connection by the following steps: 
 > # telnet    129.57.168.242 ( login: root password:dbps) 
 > # at "#>" prompt type: kill tty=2 
 > #    at "#>" prompt type: "CTRL-]" then quit 
   
 *press the "U" ( for update) if    you see the following: 

 <pre> 
 16:40:40 104% telnet 129.57.168.242 2002
