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:24567 username@hallgw.jlab.org     ( use a port number not in used on hallgw )

after from hallgw

   ssh -L24567: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

h2. Channel Map

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

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.

h1. HV

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

Trying 129.57.168.242...

Connected to 129.57.168.242.
