NI CVS-1450 Series Overview
This chapter provides an overview of the features and components of the 
National Instruments CVS-1450 Series compact vision system.
About the NI CVS-1450 Series
NI CVS-1450 Series devices are easy-to-use, distributed, real-time imaging 
systems that acquire, process, and display images from IEEE 1394 cameras 
conforming to the IIDC 1394-based Digital Camera Specification, 
Version 1.30
. The CVS-1450 Series 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 CVS-1450 device and a development 
computer allows you to display measurement results and status information 
and to configure the CVS-1450 device settings. When configured, the 
CVS-1450 device can run applications without a connection to the 
development computer.
Each CVS-1450 device 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 CVS-1450 device front panel consists of a VGA connector, an RS-232 
serial port, a 10/100 Ethernet connector, and three IEEE 1394a ports.
The CVS-1450 device also includes LEDs for communicating system 
status, DIP switches that specify 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 CVS-1450 device provide an easy means 
for preventing ground loops that could degrade signal integrity.
Caution
The isolation on the CVS-1450 device is not safety isolation.
