Radio and Television Interference
This equipment has been tested and found to comply with CISPR
EN55022 Class A and EN50082-1 (CE) requirements and also with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own
expense.
Changes or modifications to this equipment not expressly approved
by Data Translation could void your authority to operate the
equipment under Part 15 of the FCC Rules.
Note: This product was FCC-Certified under test conditions that
included use of shielded cables and connectors between system
components. It is important that you use shielded cables and
connectors to reduce the possibility of causing interference to radio,
television, and other electronic devices.
Canadian Department of Communications Statement
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de la class
A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le Ministère des Communications du Canada.

Features
The DT3130 Series provides low-cost, color frame grabber boards for
the PCI bus. These boards are suitable for both color image analysis
and machine vision applications.
Each DT3130 Series board digitizes the image, then either stores the
digitized data to the host computer’s system memory or transfers the
digitized data to the computer’s display controller to display images
in real-time. The boards transfer image data to the host computer
using PCI burst transfers.
Key features of the DT3130 Series boards are summarized as follows:
•OperateasPCIbusmasters on half-size boards.
• Support the scatter/gather memory capability using the PCI
interface chip.
• Support the following video inputs and formats:
