Online telecon notes for June 12, 2002.

Attending:

• Zhigang Wang (UCSC/TKR)
• Connie Houchens (GSFC/ACD)
• Jim La (GSFC/ACD)
• Steve Bailey (GSFC/ACD)
• Glenn Unger (GSFC/ACD)
• Mike Huffer (SLAC/ELX)
• Larry Wai (SLAC/I&T-IFCT)
• Selim Tuvi (SLAC/I&T-Online)
• Ric Claus (SLAC/I&T-Online), minutes author

I’m using outline format in an attempt to produce these minutes quicker. Maybe they read faster this way, too. Let me know whether there are objections.

• Announcement of Online release P01-02-00:
• Supports pseudo-AEM
• Supports LabVIEW interaction with SCL running on the embedded system
• Main difference from last week’s discussion is that there is now no need for non-pseudo-AEM users to upgrade their COMM card firmware
• AEM:
• Connie says she has bud box (containing pseudo-front end electronics) and she will start testing against it (commanding/event data taking)
• Connie will start producing scripts for Glenn in accordance with LAT-SS-00363-02
• Mike stressed the importance of letting Gunter and him know of documentation updates that pertain to AEM electronics design documents
• Jim La asked about the I&T Online ICD
• Ric is currently updating that document and apologizes for the delay. There is a lot to do.
• Mike discussed AEM design
• Design is progressing on the AEM. Engineer Mark Freytag is working on it.
• AEM event data format looked unimplementable last week, but now looks possible after various discussions. It matches the AEM Primer document fairly closely. However, Mike warned that things could still change.
• Location of the AEM module has physically moved in the LAT, ACD document will be updated to reflect that
• AEM hardware design to be completed in 3-4 weeks. Mike guessed that ACD can expect to receive physical boards at the end of the summer.
• Glenn guessed that ACD needs 4 units plus one spare, but will verify
• Glenn thinks that ACD can make good progress with the pseudo-AEM through October
• Glenn expects that multiple FREE cards will start becoming available in March ‘03
• Mike expects SLAC will need at least two sets of AEM and FREE cards
• Glenn doesn’t promise anything, but thinks SLAC might be able to get a FREE card in October
• Glenn asked about Mike's experience on testing of the pseudo-AEM. Straightforward except for the event data format. Some issues with the ICD that SLAC should have caught but didn’t.
• May want to make some changes to the GARC and GAFE designs if there is an opportunity. If there isn’t we can live with them as is.
• Glenn indicated that ACD is aggressively working on SCL coding
• Selim has extended the dbsrv SCL package to support Python similarly to the way LabVIEW is supported. He packaged the changes up in a patch and sent it to Byron at NRL so that CAL’s pre SCL legacy system can be used.
• Online received temInit.scl from CAL and aemRegress.scl from ACD.
• Online is working on understanding the performance issues the LabVIEW/embedded SCL bridge has presented.
