How to run CODA

From an accelerator machine: ssh -X idaq@opsmdaq0 (Note: idaq is the injector DAQ account and uses ssh authorized_keys for login - no need to enter password) and open few xterm & windows.

 xterm 1: telnet iocmdaq1

 xterm 2: msqld (the msqld database is usually running unless opsmdaq0 was rebooted)

 xterm 3: platform

 xterm 4: codamaster

Choose the configuration: Mott_Sample

When the CODA MASTER panel appears, select Config => Enable Buttons.

Select ET System, Event Builder, Event Recorder and Run Control. After doing that if you will click on Get Status you will find status of Event builder, Event Recorder and ROC1. All buttons must be green.

Select Run Control and the main CODA panel will appear.

Start and Stop a Run

After the opening of the Run Control panel, select in order:

Sessions => inj
Configurations => Cool => Mott_Sample
Platform => Connect
Configure
Download
Prestart
Start

At the end:

Stop

and if you want to apply a change or you need a new configuration:

Reset

and start from number 5.

-== How to use the VME discriminator ==
-The VME discriminator is the CAEN v895 whic has several possibilities.
-It is used in several configuration file but it must be set up correctly.
-The configurations used, at the moment, are:
-* PEPPo_Sample, PEPPo_Cosmics, Annihilation_Sample, PEPPo_SemiInt
-How to use the module, from every directory:
-   v895_config
-An user interface will appear.
-[[Image:V895_config.png]]
-PMT refer to PEPPO cristal PMTs, A1 and A2 are for annihilation counter and cosmics are for cosmic paddles.
-* Set thresholds for all the channels (thresholds are in mV) and select(tick) only channels used.
-* To set the number of channels used as to generate one trigger select the ''Majority Level'' (MJL) or coincidence.
-MJL = 1 means that, with at least one detector above the threshold, it generates the output signal.
-MJL = 3 you need at least 3 detector signals above the thresholds to generate the output signal
-For Cosmic and Annihilation configurations MJL set to 2.
-To close Coda use the codamaster panel and press ''kill all'' followed by the exit botton under 'configuration'.
-== How to use the JLAB VME discriminator ==
-One can open a GUI in from opsmdaq0
