External connection

and control

Apart from its standard mode of opera-

tion, the Dolphin offers many more sophi-

sticated trigger possibilities. Up to three

inputs and three outputs are available for

the hardware connection to the process.

Apart from the external trigger via an

external signal edge with selectable pola-

rity, the possibility to activate the captu-

ring of an image through the connection

of two signals (e.g. gate and trigger) also

exists. The gate input works as a prepara-

tory input when a part, which needs to be

controlled, comes closer. The trigger acti-

vates when the part is precisely in front of

the camera. A direct connection to an

incremental encoder over three input sig-

nals (Count, Up/Down, Reset) is also pos-

sible.

Delayed flashtrigger

An output on the camera shows the inte-

gration time so that it can be used for the

control of a flash for example. Delayed

flashes can be programmed with the

delayed flashtrigger as well.

Software

The Dolphin comes with a sophisticated

operating system (firmware) which con-

trols all functions of the camera. The large

memory is easily upgradable with client-

specific functions and meets all criteria

regarding optional demands. It doesn't

get any easier than this: the camera

doesn't even need to be opened - with the

help of a small PC program the firmware is

simply uploaded via the serial port of the

Dolphin.

AVT FirePackage

We control both sides of the cable: the AVT

FirePackage is the smart software for inte-

grating IEEE 1394 cameras into applica-

tions. Today digital cameras are just as

easy to use in image processing as analo-

gue cameras and frame grabbers - but with

much better images and higher speeds of

course.

The prerequisites for easy integration are

achieved with the AVT FirePackage.

The Dolphin family and AVT FirePackage

are compatible with all standared image

processing packages such as HALCON,

Active Vision Tools and with manufacturers

such as National Instruments MVTec and

Matrox, who support the FireWire stan-

dard.

Connectors

The 12-HIROSE connector of the Dolphin

directs all digital input and output signals

as well as the optional power supply and

the serial port. Compatible cables (inclu-

ding those to client specifications) up to

17.5 m in lengths are obtainable from

Allied Vision Technologies.
