- * Driver: ni_daq_700
- * Description: National Instruments PCMCIA DAQCard-700
- * Author: Fred Brooks <nsaspook@nsaspook.com>,
- * based on ni_daq_dio24 by Daniel Vecino Castel <dvecino@able.es>
- * Devices: [National Instruments] PCMCIA DAQ-Card-700 (ni_daq_700)
- * Status: works
- * Updated: Wed, 21 May 2014 12:07:20 +0000
- *
- * The daqcard-700 appears in Comedi as a digital I/O subdevice (0) with
- * 16 channels and a analog input subdevice (1) with 16 single-ended channels
- * or 8 differential channels, and three input ranges.
- *
- * Digital: The channel 0 corresponds to the daqcard-700's output
- * port, bit 0; channel 8 corresponds to the input port, bit 0.
- *
- * Digital direction configuration: channels 0-7 output, 8-15 input.
- *
- * Analog: The input range is 0 to 4095 with a default of -10 to +10 volts.
- * Valid ranges:
- * 0 for -10 to 10V bipolar
- * 1 for -5 to 5V bipolar
- * 2 for -2.5 to 2.5V bipolar
- *
- * IRQ is assigned but not used.
- *
