Differences among the
Lab-PC+, the DAQPad-1200,
and the DAQCard-1200
© National Instruments Corporation
This appendix contains a summary of the functional differences between
the Lab-PC+, the DAQPad-1200, and the DAQCard-1200.
The Lab-PC+ is a plug-in DAQ device for PCs. It has jumpers for allocating
bus resources such as base address, interrupt, and DMA channels, as well
as analog input/output resources such as input/output mode and polarity.
It also has potentiometers for calibration.
The DAQPad-1200 is a DAQ device that plugs into the parallel port of the
computer. It is functionally identical to the Lab-PC+. In addition, there are
no jumpers for bus resource allocation; this is done at configuration time
with software. It also has no potentiometers because it is software
calibrated. The DAQPad-1200 is register-compatible with the Lab-PC+.
It has a few additional registers for calibration purposes.
The DAQCard-1200 is register-compatible with the DAQPad-1200 (and the
Lab-PC+) and is functionally identical to it. Register-level software
developed for the Lab-PC+ works directly on a configured DAQCard-1200.
However, you calibrate the DAQCard-1200 with software instead of with
potentiometers.
