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 DT3157 frame grabber accepts video from digital input sources,
and uses the host system's system memory to store images and the
host system's display controller to display images. It is suitable for
both image analysis and machine vision applications.
Key features of the DT3157 board are summarized as follows:
• Operates as a PCI bus master;
• Accepts 8-, 10-, 12-, 14-, or 16-bit monochrome video from a
single RS-422 video channel (programmable to 2 KB x 2 KB, 4 KB
x 1 KB, or 1 KB x 4 KB), or 8-bit monochrome from two RS-422
video channels (programmable to 1 KB x 1 KB);
• Supports Kodak dual 8-bit video format (such as the Model
ES1.0);
• Supports up to 20 MHz on a single channel (8 to 16 bits), and
40 MHz for dual channels;
• Provides real-time image transfer to host memory or to the
display frame buffer;
• Provides real-time scaling via decimation up to 1/16 size (except
in dual-channel mode);
• Accepts an external trigger;
• Provides an input look-up-table that supports single- and
dual-channel mode;
• Provides eight TTL lines, each programmable as either input or
output; and
• Provides a standard SCSI-II, 68-pin, D-shell connector for I/O
connections.
