The JEI, aka the Engineering Console

• JEI Java Engineering Interface
• Based on the T-ReCS JEI
• Control Screens
• MCE4 Control Params (e.g. reads, coadds, net
  Itime)
• Detector Bias Preamp Settings
• Temperature Pressure Monitor of the Mos Dewar
• Pressure Monitor Temperature Monitor Control
  of the Camera Dewar
• Mechanism High-Level (Named Positions)
• Mechanism Low-Level (Numeric Position Control
  Parameters)
• Scripts
• EPICS Records
• System

Detector Screen (1)

• Almost everything (e.g. nodding chopping) is
  deleted.

Detector Screen (2)

• Add Adjustments for
• Single Frame Exposure Time (seconds)
• Net Desired Exposure Time if Coadding Set
  NumCoadds
• Number of Multiple Reads, otherwise CDS
• CDS Readout Modes
• output of final difference image
• Output the individual frames that make up the
  difference
• MCE4 Control Parameters to keep
• Pixel Base Clock
• Number of Pre-Resets (default 10)
• Number of Post-Resets (default 1000)

Bias Screen

• HAWAII-2 array only has 1 adjustable bias voltage
  (not 24!)
• Need 2 common biases (1) Imaging, (2)
  Spectroscopy
• Combine with Preamp Screen (?)

Preamp Screen

• HAWAII-2 array readout through all 32 output
  amplifiers ? need 32 offsets.
