NI 1450 Overview
This chapter provides an overview of the features and components on the
National Instruments 1450 Series Compact Vision System.
About the NI 1450 Series Compact Vision System
The NI 1450 Series Compact Vision System is an easy-to-use, distributed,
real-time imaging system that acquires, processes, and displays images
from IEEE 1394 cameras conforming to the IIDC 1394-based Digital
Camera Specification, Version 1.30. The NI 1450 also provides multiple
digital input/output (I/O) options for communicating with external devices
to configure and start an inspection and to indicate results.
An Ethernet connection between the NI 1450 and a development computer
allows you to display measurement results and status information and to
configure the NI 1450 settings. Once configured, the NI 1450 can run
applications without a connection to the development computer.
Each NI 1450 ships with documentation and the NI-IMAQ for IEEE 1394
Cameras driver software, which is licensed for one development system
and one deployment system.
Hardware Overview
The NI 1450 front panel consists of a VGA connector, an RS-232 serial
port, a 10/100 Ethernet connector, and three IEEE 1394a ports.
The NI 1450 also includes LEDs for communicating system status, DIP
switches for mode control for specifying startup options, TTL inputs and
outputs for triggering, and isolated inputs and outputs for connecting to
external devices, such as PLCs, sensors, LED indicators, and start/stop
buttons. The isolated inputs and outputs on the NI 1450 provide an easy
means for preventing ground loops that could degrade signal integrity.
Caution The isolation on the NI 1450 is not safety isolation.
