What’s in progress
• LabVIEW  VxWorks SCL connection
– Just about complete
• Pseudo-AEM implemented in a LAT-COMM card
– Anticipate deployment first week of June

Near term plans
• Run control
– For coordination of data-taking
• FITS data files
• Visualization tool
– Selection and integration
• Supplementary test equipment support
– GPIB
– Industry Packs digital and analog I/O
 Subsystem input requested to achieve the proper mix of types
 Would like to keep the number of types of supplementary
equipment small to manage the work load

Wrap-up
• Delivery of initial 16 test-stand workstations complete
– Online holds on to two configured spares
• Discussions in progress with subsystems on script, database
and GUI screen creation and tuning
– Online to collect completed subsystem contributions
• Weekly Online meeting scheduled to facilitate feedback (in both
directions)
• Adaptation to changing electronics prompts new releases
• Code Versioning System set up
• Build and distribution mechanisms set up
• Created Web site and forum for information exchange and
system updates:
http://www-glast.slac.stanford.edu/LAT/INT/ONLINE/Default.htm
• Documentation updates in progress
