Work Completed

VME Hardware

All VME and Allen-Bradley modules installed

Other Hardware

• Order 1 UPS 1400. This will be used for the VME crates and terminal server - $749.00
• Order 1 XYCOM 203/293 Counter Module w/quadrature  - $1000.00

VxWorks

• Kernel modifictaions for powerPC
• Build EPICS source for the powerPC processor (base,site,app)
• Download VxWorks Boot image into the powerPC onboard FLASH

EPICS device/driver/record support

Timeout software added to the CaenV265ISR. (testing needs tobe done)

Generic EPICS VME Card Record added. This provides module information such as status, bus address,status register,etc. This record is used for diagnostic purposes.

Merged Lecroy 1176 TDC Waveform device support into VME Card Record.

Subroutine record for accelerator structure logic

EPICS Database

• Accelerator structure logic

EPICS and SCP Displays

• Add fast data acquisition pv's to EPICS displays.
• Created new EPICS displays and strip charts for fast data acqusition.
• Created SCP Correlation Plots (Toni)

EPICS Channel Archiver and VME History Buffering

• Setup and configuration files
• Archiving channels for charge integrating adc:  ENERGYON,ENERGY,ENERGYMIN,ENERGYMAX,ENERGYAVE

Miscellaneous VMS Work

SIP setup

Work In Progress

• CaenV265 parts from should arrive at Wiener, the US distributor this week. Andreas Ruben will overnight the parts to SLAC when they arrive at Wiener.
• A solution to the bad channel data on the positive Caen V265 modules has been found by Jeff Olsen and Mike Brown. A fix is currently being implimented.
• Determine if the bus speed on the Motorola MVME2700 can be changed in software.
• Save-Restore files
• Set database limits (alarm and operating limits) in databases templates.
• Web page documentation
• Add fields to VME Card Record to support 16 individual inputs
• Add CaenV265 Record fields to account for timeout errors:  TCNT, OCNT, TTIM, TACK
• Add error metering for missed pulses
• Complete database work for fast data acqusition
• CaenV265 channel calibration and database coefficient update.

Work To Do

• Sequence for ramping DAC
• Modifiy existing driver and device support for Joerger VTR 812 analog digitizer for the VTR 812/10
• VMS Configuration Files
• EPICS Display help files
• Need to setup hardware reset of VME crates. This will require two IDOM channels assigned
• Load test with  powerPC running EPICS fast data acquisition software
• Test CaenV265 Record fields:   MRST,FLSH and LCK
• Connect channel on VMIC 4100 DAC to voltmeter to check output
• Connect TDC channels to real data.
• Connect hadwar to a start (pdu) and stop (do)  trigger so that the time between when the 60Hz gate is issued and the database lockset has completed. The goal is to determine how much time we have before the next get is expected.

Final purchases

• Hard disks for data storage  (???)
• Spare VME modules (???)
