PALM-3000 P3K Team Meeting #9 Stephen Guiwits Team Meeting #9 and 023 Robinson October 22, 2008

PALM-3000 P3K Electronics Documents Electronics Requirements Document Interfaces.xls –Requires more detail Electronics Project Schedule Design Document –In the works

PALM RTC Hardware Software Installation and Test Suse Kickstart DVD Install –Complete –Custom RPMS completed and tested –Custom scripts to install Nvidia development libs Quadrics drivers EDT drivers –2 disks Disk 1 = Base + patches Disk 2 = custom scripts Quadrics Installation –Quadrics switch installed and configured –Linux driver installed –Initial communication tests completed

PALM RTC Hardware Software Installation and Test Development Rack –Will be installed next week and set up in JPL AO Lab Production Rack –Will have the initial Suse kickstart release installed next week –Will be shipped to Caltech within the following weeks

PALM-3000 RTC Rack Layout 5

PALM-3000 DM Driver Hardware –Xinetics Gen III Mirror Electronics Software –Initial test software written –Reads in command line arguments or files –Communicates over the RS 232 interface –Needs to be cleaned up and put into a linkable library Results –Able to set the driver state to active and send commands successfully

PALM-3000 DM Driver Results –Several commands are still not working ‘B’ – set the bias voltage ‘C’ – set the frame size (currently have to send full frames) ‘D’ – read the driver type Rest of the command set still needs to be tested –To complete this week Working with Xinetics –Need to actively work with Xinetics to make sure we have all the commands working required for P3K operation

PALM-3000 P3K Cassegrain Cage Racks Space Required –Require 4 rack spaces on the cassegrain cage –Two 30U for the DM electronics –Two 24 U for the general AO electronics –These spaces do not include the instrument cage

PALM-3000 P3K Cassegrain Cage Racks Locations –DM Drivers in 2 and 3 –General racks in 4 and 5 –Instrument rack in 6 This has not been confirmed by Palomar but should be possible I’ve been told

PALM-3000 P3K General Rack Rack One

PALM-3000 P3K General Rack Rack Two

PALM-3000 DM Electronic Cooling Early stages of design: Cooling lines –Facility class or AO only –Must work in AO lab Alcohol and Water vs. Glycol All racks vs. just DM Flow rate / Vibration / Noise

PALM-3000 P3K Power P3K Power Requirements Given to Palomar Staff Major power and infrastructure upgrades needed for 200” No shared UPS for RTC Racks UPS for DM electronics?

PALM-3000 P3K Cabling Cabling design –Overall design and documentation to begin soon –DM cabling already in the works Dean working on DM cabling and has made some significant progress –Cabling from FPGA to “magic box” –“Magic box” to DM drivers –Currently working on a quick connect from the DM drivers to the mirror to speed up instrument installation and eliminate errors

PALM-3000 P3K Cabling

PALM-3000 Procurements Cassegrain Cage Computer –Spec’d and quoted SciMeasure Optical Splitter –Gave Charlie B. until December 1, 2008 to produce a quote FPGA Cards –Spec’d and quoted DVI KVM Switch –For Production RTC Racks –Quoted and Ordered
