  29Driver: ni_labpc_cs
  30Description: National Instruments Lab-PC (& compatibles)
  31Author: Frank Mori Hess <fmhess@users.sourceforge.net>
  32Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
  33Status: works
  34
  35Thanks go to Fredrik Lingvall for much testing and perseverance in
  36helping to debug daqcard-1200 support.
  37
  38The 1200 series boards have onboard calibration dacs for correcting
  39analog input/output offsets and gains.  The proper settings for these
  40caldacs are stored on the board's eeprom.  To read the caldac values
  41from the eeprom and store them into a file that can be then be used by
  42comedilib, use the comedi_calibrate program.
  43
  44Configuration options:
  45  none
  46
  47The daqcard-1200 has quirky chanlist requirements
  48when scanning multiple channels.  Multiple channel scan
  49sequence must start at highest channel, then decrement down to
  50channel 0.  Chanlists consisting of all one channel
  51are also legal, and allow you to pace conversions in bursts.
