* 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 .
