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.
