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.

Available Camera Bandwidth
The IEEE 1394 bus provides a fixed amount of bandwidth that is shared
among the three IEEE 1394a ports on the NI 1450. These ports provide
direct connection to up to three DCAM-compliant IEEE 1394 cameras,
depending on the amount of bandwidth each camera requires. Higher frame
rates and larger image sizes require a higher data transfer rate and use more
bandwidth.
Table 1-1 shows the maximum number of cameras the NI 1450 supports for
three common video formats. Use this table as a guide when determining
the combination of cameras to use in your application. The maximum
number of cameras listed in the table does not include processing time.
By triggering your cameras slower than the frame rates listed in the table,
you can operate more cameras simultaneously. If the camera combination
exceeds the amount of available bandwidth, the software returns an
Insufficient Resources error.

Chapter 1 NI 1450 Overview
Software Overview
Programming the NI 1450 Series Compact Vision System requires the
NI-IMAQ for IEEE 1394 Cameras driver software, version 1.5 or later,
to control the hardware and one of the following application software
packages to process images.
• NI Vision Builder for Automated Inspection (AI), version 2.0 or
later—To configure solutions to common inspection tasks
• LabVIEW Real-Time (RT), version 7.0 or later, with the Vision
Development Module, version 7.0 or later—For customizable
control over acquisition hardware and algorithms
The following sections provide an overview of the driver software and the
application software. For detailed information about individual software
packages, refer to the documentation specific to the package.
NI-IMAQ for IEEE 1394 Cameras Driver Software
The NI-IMAQ for IEEE 1394 Cameras driver software ships with the
NI 1450 Series Compact Vision System. NI-IMAQ for IEEE 1394
Cameras is the interface path between the application software and the
NI 1450.
NI-IMAQ for IEEE 1394 Cameras includes an extensive library of VIs
you can call from LabVIEW. These VIs include routines for video
configuration, image acquisition (continuous and single-shot), trigger
control, and register-level camera configuration.
The NI-IMAQ for IEEE 1394 Cameras driver software performs all
functions necessary for acquiring and saving images but does not perform
image analysis. For image analysis functionality, refer to the National
Instruments Application Software section.
For maximum flexibility and performance, NI-IMAQ for IEEE 1394
Cameras features both high-level and low-level functions. A function that
acquires images in multi-buffer, single-shot, or continuous mode is an
example of a high-level function. A function that requires advanced
understanding of the NI 1450 and image acquisition, such as configuring
an image sequence, is an example of a low-level function.
The NI-IMAQ for IEEE 1394 Cameras software handles many of the
complex issues between the NI 1450 and the camera, such as 1394 bus
communication and camera control.

Before Getting Started: Connecting the NI 1450 to a Network
Use a standard Category 5 or Category 6 Ethernet cable to connect the
NI 1450 to an Ethernet network.
If the development computer is already configured on a network, you must
configure the NI 1450 on the same network. If the development computer
is not connected to a network, you can connect the two directly using a
Category 5 or Category 6 crossover cable.
Caution To prevent data loss and to maintain the integrity of your Ethernet installation,
do not use a cable longer than 100 m. If you are using a 100 Mbps Ethernet, National
Instruments recommends using a Category 5 or Category 6 shielded twisted-pair
Ethernet cable.
