OTR Data Acquisition

General or EDM ....

to be completed...

EPICS PVs

• Note, you must have sourced lwprofile to get any of these PVs on extlw-lxs1

To add extra PVs you open the db template in the editor and then db itself, then edit, save and then start and stop the whole database for everything - not on shift!!!

cd extlw/daq/ioc/dbd
vdct otr.dbd

• File->Open. Open ../db/otr.db

Right click on black space -> new record. Box pops up. Type desired name and type - 'ai' for number, 'string' for string, 'waveform' for array. Drag to look nice. Double click to edit properties.

Save & exit. Go to lw run directory.

./extlw.sh stop
.... wait for it to save values...
./extlw.sh start

• Do not do on shift - that's what spares are for.

Camera

• Camera is controlled through c++ interface to 64bit driver
• C++ is wrapped in DLL for Labview
• Labview calls DLL in various subvis, wrapped in main loop vi
• Main loop vi interprets commands and accepts parameters from EPICS

Startup

• Remote desktop to extlw-win4
• Start:

extlw/daq/labview/extlw-win4/extlw-win4.lvproj -> otrcamera.vi -> run

Commands

DLL

• DLL is in some folder - update

To change:

• Update code in Microsoft Visual Studio Express 2010
• Build>Build
• Copy DLL and associated files in same directory - about 6 files located in *some folder - update*/Debug to
• extlw/daq/labview/extlw-win4/otrcamera/
• chmod 755 * -R this folder
• use LabView vi now from extlw-win4 project

LabView Control of Camera
