Notes on CE-Conformance and Immunity against
Interference
Upon delivery, the pciGrabber-4x4 meets all CE-requirements for
household, office, manufacturing and industry. User modifications of
the Grabber without permission of the manufacturer will result in the
cancellation of the CE-certificate.
CE-conforming use of the Grabber is only maintained by utilizing
CE-certified cables. These cables can be separately purchased from
PHYTEC as accessories for the pciGrabber-4x4 (see chapter 2.1). If
other cables are installed the user must ensure CE-conformity. If the
S-Video cable WK-051 is used a ferrite of the type # 742 716 32 from
Firm Würth, Kupferzell, Germany is required
If the user plans to connect the pciGrabber-4x4 with other cables, it is
recommended that these cables are fitted with an anti-interference
clamp or comparable interference suppression devices. The clamp
should be placed about 5 cm from the Grabber and, the cable should
be looped twice through the clamp.
For video cables a ferrite type # 742.711.4 from Firm Würth,
Kupferzell, Germany is suitable.
The cable shielding has to be connected to the connector shell to
obtain an optimum of shielding.
The pciGrabber-4x4 was tested for a standard PC environment. If the
device should be used in a different environment, it has to be exam-
ined if additional radio shielding is necessary.
Caution:
Please pay attention, that significant interference peaks (ESD) to the
video signal or video ground might damage the input of the
pciGrabber-4x4.
In areas with high interference level, for example in industrial areas
and using long feed lines, additional precautions have to be taken to
suppress interference. Long video cables, or mounting the components
for image processing into plants and machines, can cause the
exposition to balancing currents, which have to be eliminated from the
