Chapter 1: Introduction
The Allegro CX™, combined with the Data Acquisition Expansion
Pod™ (“DAQ Expansion Pod™”), places the functionality of
National Instruments’ DAQCard into the palm of your hand. The
DAQ Expansion Pod maintains the environmental seal of the Allegro
CX unit while still bringing you the interface capability of the NI
DAQCard. The DAQ Expansion Pod takes advantage of the NI
DAQCard’s wide range of data acquisition capabilities. Coupled
with National Instruments’ LabVIEW PDA graphical programming
environment, the DAQ Expansion Pod brings a powerful new
perspective to any application requiring rugged handheld data
acquisition.
Physical Description
The DAQ Expansion Pod consists of an Allegro CX expansion
pod fitted with a 50-pin D connector that channels data from
the NI DAQCard to the connector through a flexible circuit. The
functionality of the NI DAQCard is enhanced by the Allegro CX
expansion pod through the addition of a Sensor Excitation output.
The Sensor Excitation Output is capable of supplying 200mA of
output current at a voltage of 0 to 4.8 volts (as specified by the
Analog Output 0 or AO0), perfect for powering external sensors.
