EEL 122 test setup
The test setup in EEL was upgraded from CAMAC to a VME based.
The modules in use there are :
V795 0AA1 ( 1AA0 )
Booting the CPU
boot device : dc unit number : 0 processor number : 0 host name : yer122 file name : /home/vx/kern/5.5/vx2306_FD inet on ethernet (e) : 126.96.36.199:ffffff00 host inet (h) : 188.8.131.52 gateway inet (g) : 184.108.40.206 user (u) : vx ftp password (pw) : vxworks111 flags (f) : 0x20 target name (tn) : eeltest startup script (s) : eeltest-yer122.boot

Analyzing the data
To take data one should use CODA running on the computer on the right side to it. It is called yer122. ( update yer122 is broken so for now use shortrange-tc computer instead of yer122 )
Login using the adaq account.
you can ssh on shortrange-tc (yer122) or do "su adaq"
And type ./startcoda
This will start CODA components and runcontrol.
In runcontrol, click on connect. Then choose configure and select the eel122 configuration and take runs.
The cabling is usual for such a VME setup and is illustrated in the following figure.
To look at the data, copy the coda file which should have appeared in the CODA directory : test???.dat to a computer where the analyzer is installed and use the macro decodeEel.C located at 
Special for Albert since analyzer does not work on yer122 until I upgrade the linux :
scp data141.dat shahinya@ifarml3:replay/eel122/
Log in on ifarml3 :
ssh -Y shahinya@ifarml3
go in the replay directory :
Launch analyzer :
and start decoding
when done you can look at all tdc channels :
To directly plot from the ntuple, the ntupe is called tdata :
You can launch it in line : analyze decodeEel.C\(60\) where 60 is the run number you want to look at.
Or interactively :
this will generate a root file containing the tree tdata which holds the data for adc ( array of 32 integers ) and tdc ( same ).
To look at on particular channel : tdata->Draw("tdc");
will plot the tdc spectrum of channel 5 ( 6th channel since we start at 0 )
