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

7
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

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

9
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 Ive been told

10
DM Rack Designs

• Rack One

P3K General Rack

• Rack One

13
P3K General Rack

• Rack Two

14
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

15
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?

16
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
