Digital I/O Functionality
This chapter describes the primary functions of the digital inputs and
outputs on the NI 1450 Series Compact Vision System. This chapter also
includes guidelines for connecting the digital I/O and for setting up a
typical NI 1450 system.
Overview
The digital I/O functions are accessible through 2 TTL inputs, 10 TTL
outputs, 13 isolated inputs, and 4 isolated outputs.
Input signals can be used as triggers, product selection ports, to read
quadrature encoders, or they can be user-defined. Uses for output signals
include controlling camera reset and exposure, controlling strobe lighting,
outputting inspection results, communicating with PLCs, or they can be
user defined.
For information about how to use LabVIEW RT to implement specific
digital I/O functions, refer to the application software documentation and
examples in the following locations:
• Program Files\National Instruments\NI 1450 Series\Docs
• Program Files\National Instruments\LabVIEW 7.0\

The NI 1450 Series Compact Vision System Digital I/O Help is available
for each example. This help file contains digital I/O reference information
and instructions for using the LabVIEW FPGA VIs.
