The DaqBoard/2000 Series has a 16-bit, 200 kHz A/D coupled with 16 single-ended, or 8 differential analog inputs. Each channel can be software-configured for a different voltage range, as well as for single-ended or differential, and unipolar or bipolar input. While all analog input ranges on the DaqBoard are calibrated at the factory, the DaqBoard also allows user calibration through a separate program called DaqCal. This software stores its calibration results in tables that are separate from factory calibration.

Forty TTL-level digital I/O lines are included in the DaqBoard/2000 Series. They are divided into three 8-bit ports (P2) and one 16-bit port (P3). Also, four 16-bit counters are built into the DaqBoard/2000. The analog, digital, and counter inputs all can be read asynchronously under program control, or synchronously as part of an analog and digital scan group.

The DaqBoard/2000 Series supports Bus Mastering DMA, which allows analog and digital/counter input data, as well as analog and digital output data to flow between the PC and the DaqBoard/2000 Series without consuming valuable CPU time. The driver supplied with the DaqBoard/2000, as well as all other third-party software support such as DASYLab®, NI LabVIEW™, and MATLAB®, automatically utilize Bus Mastering DMA.

Signal Conditioning and Expansion
The DaqBoard/2000 Series is supported by over 40 signal conditioning and expansion options, offering signal conditioning for thermocouples, RTDs, accelerometers, isolation, high-voltage, strain gages, and much more. Up to 528 channels of analog and digital I/O can be accessed using one DaqBoard/2000, while maintaining the 5 µs per channel update rate. Up to four DaqBoard/2000s can be installed into one PC and operate synchronously.
