Camera Link is a new digital transmission method,

for the machine vision industry, in answer to customer

requests. It is an easy way to connect digital cameras to

frame grabbers.

Camera Link is a camera-to-frame grabber

interface specification based on an implementation of

Channel Link™ technology. It includes hardware (cable

connectors), & data transmission as well as camera

control and asynchronous serial communications all on

a single cable. Now, only two connections (power and

Camera Link) are required to operate the camera.

The specification was developed through an

initiative headed by PULNiX America, Inc. Camera Link

defines a single connector for both the frame grabber

and the camera. This insures that all products bearing

the Camera Link logo are interchangeable with each

other. The official Camera Link logo is shown to the

right.

As a standard that has been defined by industry

members, Camera Link provides the following benefits:

•

Real-time signaling: Camera Link supports real-time

signaling. Camera Link cameras accept signals includ-

ing asynchronous reset (Vinit), HD, VD, and integration

through the Camera Link cable, without latency (delay).

•

High data rates: A base configuration Camera Link inter-

face can handle 1.2Gbps of data. The technology used in

Camera Link has a maximum data rate of 3.5Gbps, insur-

ing solutions for tomorrow’s applications.

•

Flexibility: Camera Link is independent of imager

resolution, video format, and frame rate. In contrast,

some other digital transmission standards are set for

specific pre-defined video formats.

•

Platform independence: Camera Link is a hardware

specification designed by camera and frame grabber

manufacturers specifically for the Machine Vision industry.

The frame grabber software must be Windows™ 9X/2000

compatible, but is independent of support from third

parties like Microsoft, Apple, or Intel.

•

Simple interface: Only two connections are required to

interface a camera and frame grabber: Power and Camera

Link. Cameras and frame grabbers can be easily inter-

changed using the same cable.

•

Standardized cable assembly: Camera Link specifies a

standard cable assembly. This eliminates the need for

manufacturers to provide custom cables, and allows

customers to take advantage of lower cable prices. In

addition, the technology used in Camera Link reduces the

number of wires required to transmit data, allowing for

thinner cables, which are more robust and less prone to

breakage. Various cable lengths are available up to 10m.

•

Extensive application software support from frame

grabber and vision software companies: Machine vision

applications require robust and field-proven software.

Camera Link is a quick and simple way for users to stan-

dardize their systems for existing applications without

having to verify new software.

•

Long-term, stable supply: Channel Link technology is

committed to providing long-term support to the telecom-

munications industry. Unlike most consumer products, the

basic architecture will remain stable for many years to

come.
