| − | In the DAQ crate we are using an old Trigger Interface (TI) board, i.e. the triggers are distributed through front pannels.
| + | This page has moved to https://halldweb.jlab.org/wiki-private/index.php/Private:UConn_test_setup |
| − | The SDC board is used for the trigger and clock distributions to fadc250.

| − | '''Setting up the setup'''
| + | |
| − | | + | |
| − | * Connect keybord and monitor (if needed) to the Intel ROC.
| + | |
| − | * Connect Ethernet cable to the upper ROC LAN connector.
| + | |
| − | * Change ROC IP address (you will see the MAC address when you start booting the controller)
| + | |
| − | * Login under '''halld'''
| + | |
| − | | + | |
| − | ''' Directories '''
| + | |
| − | | + | |
| − | Most DAQ files (CODA), the Run Control and other applications have been installed locally on the ROC flash disc.
| + | |
| − | You will need to mount the remote data disc to store data files.
| + | |
| − | | + | |
| − | Below is a description of some directories:
| + | |
| − | | + | |
| − | * The home directory is '''/home/halld'''
| + | |
| − | * '''/home/halld/micro/rol''' contains the F1TDC configuration file and the link to the DAC readout list (see descriptions below)
| + | |
| − | * '''/home/halld/micro/coda''' contains Run Control data base
| + | |
| − | * '''/home/halld/data''' is a directory for the DAQ data storage. The external drive has to be mounted to here
| + | |
| − | * '''/home/halld/micro/coda_micro_setup''' is a script with configuration variables
| + | |
| − | ** you have to edit this file ad change some variables if needed
| + | |
| − | ** '''source coda_micro_setup''' to set variables up
| + | |
| − | * Coda and Run Control files are installed at '''/usr/local/coda/2.6.1'''
| + | |
| − | | + | |
| − | ''' How to run DAQ '''
| + | |
| − | #Launch database daemon
| + | |
| − | #* After changing the ROC hostname, the Run Control database (where the host name is used) has to be updated.
| + | |
| − | #* Login to the controller under '''halld''' and set up environmental variables ( source coda_micro_setup )
| + | |
| − | #* start mysql deamon by typing '''msqld''' ( be sure that only one msqld is running)
| + | |
| − | #* use '''cedit''' to change host names for the event builder (EB5) and coda ROC (TROC5)
| + | |
| − | #** to do this, select File->Open Database->micro_test and File->Open->Run Type->simple and click on EB5 and TROC5 components
| + | |
| − | #* '''msqld''' has to be running all the time when you run DAQ
| + | |
| − | # Launch Afec-1.4 platform
| + | |
| − | #* login to the ROC under halld
| + | |
| − | #* type 'platform'
| + | |
| − | # Start event builder
| + | |
| − | #* login to the ROC under halld
| + | |
| − | #* coda_eb_rc3 -i -s simple -n EB5 -t CDEB
| + | |
| − | # Launch coda_roc on the Linux controller
| + | |
| − | #* login to the ROC under halld
| + | |
| − | #* coda_roc_rc3 -i -s simple -n TROC5 -t ROC
| + | |
| − | # Launch Run Control GUI
| + | |
| − | #* login to the ROC under halld
| + | |
| − | #* type 'rcgui'
| + | |
| − | #:: Select 'Sessions -> simple'
| + | |
| − | #:: Select 'Configurations -> Cool -> simple' (see top menu)
| + | |
| − | #:: Press buttons: Configure, Download, Prestart, Go (you start the run)
| + | |
| − | #* '''Note''', every time you change the database (like a hostname) you have to import it to the Run Control. To do this, in the rcgui click Options->Coda2 Database->RunTypes and select corresponding DB RunTypes
| + | |
| − | #* Direct data output: file or none. Open dbedit (Database: micro_test, Table: simple) and change EB5 outputs either to '''coda''' (write to file) or
| + | |
| − | #::to '''none''' (don't write to file). Don't forget to import the db changes in the Run Control (see note above).
| + | |
| − | ''' Change electronics boards initialization parameters '''
| + | |
| − | * The initialization of electronics modules and reading out data from FADC250 and F1TDC is handled by:
| + | |
| − | :: /usr/local/coda/2.6.1/extensions/fadcV2/v2.0/rol/fadc_list.c
| + | |
| − | :: see the code for definition of most parameters
| + | |
| − | * If you change some parameters, you will need to recompile this program: '''make clean; make'''
| + | |
| − | ''' Event analizer'''
| + | |
| − | * You can find an example of the simple event analyzer at JLab:
| + | |
| − | :: '''ifarml64:/group/halld/Subsystems/trigger/uconn'''
| + | |
| − | * Copy this directory and '''/group/halld/Subsystems/trigger/coda''' (directory with evio libs) to your local place
| + | |
| − | * Copy and modify accordingly the script file with environmental variables /group/halld/Subsystems/trigger/set_env
| + | |
| − | * Use '''make''' to compile
| + | |
| − | * '''ucon data_file''' will create a simple root file
| + | |
| − | :: see code for details
