32 Devices: [National Instruments] DAQCard-1200 (daqcard-1200)
35 Thanks go to Fredrik Lingvall for much testing and perseverance in
36 helping to debug daqcard-1200 support.
38 The 1200 series boards have onboard calibration dacs for correcting
39 analog input/output offsets and gains. The proper settings for these
40 caldacs are stored on the board's eeprom. To read the caldac values
41 from the eeprom and store them into a file that can be then be used by
42 comedilib, use the comedi_calibrate program.
44 Configuration options:
47 The daqcard-1200 has quirky chanlist requirements
48 when scanning multiple channels. Multiple channel scan
49 sequence must start at highest channel, then decrement down to
50 channel 0. Chanlists consisting of all one channel
51 are also legal, and allow you to pace conversions in bursts.
