  23 Driver: ni_labpc_cs
  24 Description: National Instruments Lab-PC (& compatibles)
  25 Author: Frank Mori Hess <fmhess@users.sourceforge.net>
  26 Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
  27 Status: works
  28
  29 Thanks go to Fredrik Lingvall for much testing and perseverance in
  30 helping to debug daqcard-1200 support.
  31
  32 The 1200 series boards have onboard calibration dacs for correcting
  33 analog input/output offsets and gains.  The proper settings for these
  34 caldacs are stored on the board's eeprom.  To read the caldac values
  35 from the eeprom and store them into a file that can be then be used by
  36 comedilib, use the comedi_calibrate program.
  37
  38 Configuration options:
  39   none
  40
  41 The daqcard-1200 has quirky chanlist requirements
  42 when scanning multiple channels.  Multiple channel scan
  43 sequence must start at highest channel, then decrement down to
  44 channel 0.  Chanlists consisting of all one channel
  45 are also legal, and allow you to pace conversions in bursts.
