+ * Driver: ni_labpc_cs
+ * Description: National Instruments Lab-PC (& compatibles)
+ * Author: Frank Mori Hess <fmhess@users.sourceforge.net>
+ * Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
+ * Status: works
+ *
+ * Thanks go to Fredrik Lingvall for much testing and perseverance in
+ * helping to debug daqcard-1200 support.
+ *
+ * The 1200 series boards have onboard calibration dacs for correcting
+ * analog input/output offsets and gains. The proper settings for these
+ * caldacs are stored on the board's eeprom. To read the caldac values
+ * from the eeprom and store them into a file that can be then be used by
+ * comedilib, use the comedi_calibrate program.
+ *
+ * Configuration options: none
+ *
+ * The daqcard-1200 has quirky chanlist requirements when scanning multiple
+ * channels. Multiple channel scan sequence must start at highest channel,
+ * then decrement down to channel 0.  Chanlists consisting of all one channel
+ * are also legal, and allow you to pace conversions in bursts.
+ *
+ * NI manuals:
+ *   340988a (daqcard-1200)
