Differences between the PC-LPM-16 and the
DAQCard-700
This appendix contains a summary of differences between the PC-LPM-16 and the
DAQCard-700 that may be relevant to you if you are a current PC-LPM-16 user. For a summary
of programming differences, refer to the DAQCard-700 Register-Level Programmer Manual.
The DAQCard-700 is compatible with the PC-LPM-16. Software developed for the PC-LPM-16
using NI-DAQ or LabWindows routines, as well as LabVIEW virtual instruments (VIs) for the
PC-LPM-16, typically work with the DAQCard-700 without modification. The following table
summarizes the significant differences.
