1.3 Field of Applications and Safety Regulations
Please pay attention to the specified operation directives of the
eGrabber-4plus. Before starting operation please read carefully the
manual.
•The eGrabber-4plus is designed for the digitization of video signals
from standard TV-cameras. Signals from composite-video cameras
can be processed, which comply with CCIR B, G, H, I and the sub
standard CCIR B, G, H, I/PAL. In addition signals compliant to
CCIR M/NTSC can be applied. Also separate luma and chroma
signals from cameras, which correspond to the S-video standard
are applicable (channel 9 only).
-The digitization is achieved in real time. The image data are
transferred via the PCI-bus of the PC. The transfer rate corresponds
to the access time specified for the PCI master slot.
-The effective transfer rate must be re-oufficient to handle the
volume of the image data, otherwise information might be lost.
•The eGrabber-4plus is intended for use in PC/104-plus systems.
The eGrabber-4plus has to be plugged into a master PCI-slot.
When assembling the PC/104-plus system and installing the
housing, applicable CE-norms must be taken into consideration.
-The board is designed to operate in dry and dustless environment.
For applications in industrial environment you have to consider to
take additional protective arrangements especially against radio
interference and safety hazards.
•The application of the Grabber board in safety areas, for aviation
and space and for nuclear or military purposes requires our
examinations and our agreement.
•For industrial applications all rules for prevention of accidents and
the rules of the employer’s liability insurance association for
electrical facilities are to observe.

Delivery Contents / Technical Data
PHYTEC Meßtechnik GmbH 2004 L-608e_4 9
•Before starting the operation of the Grabber board, it must be
ensured, that the device is appropriate for the application and the
specific location. In case of doubt, you should ask experts or the
manufacturer.
•The product has to be protected from hard shocks and vibrations.
Eventually the device has to be padded or cushioned, but the
ventilation may not be obstructed.
•In need of repair only a specialist should be asked, who uses the
original spare parts. For the installation of the Grabber, use only
tested and approved cables. Only radio shielded cables should be
utilized.
1.4 Addresses and Resources
The eGrabber-4plus occupies a region of 4 kBytes in the main
memory of the PC for the local registers. The addressing region is
automatically specified by the PCI-BIOS and no hardware wiring
(jumper setting) is required.
Only the position of the card in the PC/104-plus system has to be set
with the help of Jumper JP201 (see section 2.1). Up to three eGrabber-
4plus can be installed in a single system. Several eGrabber-4plus can
be installed in one system. The boards are configured automatically by
the BIOS for different addresses.
It is not possible to determine which board is configured to which
address. The base address of each board can be obtained by the
PCI-BIOS. For the eGrabber-4plus the driver software determines the
address via the BIOS and defines a device number. The driver also
can determine the number of boards within the system and is able to
control each board by its particular device number.

eGrabber-4plus
10 PHYTEC Meßtechnik GmbH 2004 L-608e_4
Note:
It is not possible to determine which board will be specified by which
device number. This will be done only by the PCI-BIOS and the
architecture of the CPU-motherboard. Usually the addresses are
allocated in sequence of the numbering of the PCI-slots. This might
deviate for different manufacturers.
The eGrabber-4plus will activate an interrupt in case of certain events
or a distinct operational status.
Since the Grabber is only a single function device only the interrupt
line /INTA of the PCI-bus can be used. To this PCI-bus-interrupt an
interrupt of the PC is allocated via the BIOS, so that the program can
react to this event.
The source of the interrupt can be determined from the interrupt status
register of the Grabber.
Caution:
Since several boards can trigger the same interrupt /INTA, it must be
determined which board caused the interrupt.
mWhen the PC is switched on the PCI-BIOS will recognize the new
card. This is shown by a corresponding report.
mFor function control we recommend the demo-software on the
included CD.
