MX User's Meeting - November 3, 2000

Presentations

• New MX drivers written since the January meeting.
• Current MX motor drivers.
• Multichannel scaler quick scan.
• Multichannel analyzer support.
• ADC table pseudodevice driver.
• MX server control GUI
• Some topics for discussion.

• mxplot - designed to replace Gnuplot for scan displays

Discussion

• Coordinate system driver for MX.
• Struck channel 1 can be used as a channel advance.
• Have the PMAC send channel advance to the Struck based on changes in motor position.
• Increase the binning density (smaller bin width) as signal intensity increases.
• Automatic setup. Quickly scan for the monochromator peak and slow down as the intensity increases.
• The PMAC has 16k bytes of capture memory. This can be used by quick scans.
• Write PMAC-based digital I/O and scaler drivers for MX.
• The PMAC supports interpolation of sinusoidal encoder signals. x 256 and x 4096 interpolation add-on boards are available.
• Write MX interface drivers to support the PMAC via UMAC, USB, and Firewire. A virtue of Firewire is the fact it uses fiber optics.
• Write a PMAC parameter save and restore program.

• Unified save/restore program for PMAC variables, EPICS variables, MX variables, etc.
• Unified GUI for database parameter modification and database construction.
• Use CVS to make a history of changes to the database.
• Encode record field defaults as strings and use the normal token parsing routines.
• Add an enum field type.
