| 30 | Description: National Instruments Lab-PC (& compatibles) |
| 31 | Author: Frank Mori Hess <fmhess@users.sourceforge.net> |
| 32 | Devices: [National Instruments] DAQCard-1200 (daqcard-1200) |
| 33 | Status: works |
| 34 | |
| 35 | Thanks go to Fredrik Lingvall for much testing and perseverance in |
| 36 | helping to debug daqcard-1200 support. |
| 37 | |
| 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. |
| 43 | |
| 44 | Configuration options: |
| 45 | none |
| 46 | |
| 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. |
