Chapter 1
Introduction
The U519 InstaScan scanner and the Dura-label Radio Frequency
(RF) tag developed by SCS are state-of-the-art data gathering
and inspection systems that combine sophisticated Interactive
Identification technology in a compact form factor. This unique synergy
allows our system to integrate seamlessly into —and significantly increase
productivity for —a wide range of applications and environments.
This system consists of the following components:
A scanner that is capable of writing information to and reading
information from Dura-labels using a read/write head (antenna).
The scanner conforms to FCC Part 15 specifications and can operate
with one to nine externally connected antennas.
Dura-label RF tags that contain information programmed by the
scanner. These tags are designed to store information under extremely
harsh environments without requiring a battery, and the read/write
Dura-labels can store a permanent record of multiple events and
transactions.
Communications between the scanner and the tags are conducted using
a revolutionary two-way technology that provides superior advantages
over conventional communication methods. The specific data being
communicated, and the amount of interaction you have with the scanner
and tag, are determined by your application.

Advantages
Data-gathering systems such as bar code readers use one-way
communication: a sensor reads information from a device, without any
interaction between the two devices.
Moreover, bar code systems are subject to line-of-sight limitations. As a
result, airborne contaminants such as dust, dirt, oil, and mist, as well as
label damage and objects residing outside the line of sight, result in
inefficient and erroneous results.
The SCS Interactive Identification System overcomes these
restrictions by using state-of-the-art technology. This technology
allows the scanner and tag to conduct ongoing two-way
communications that are not restricted by line-of-sight
constraints.

This unique capability allows:
• Collective or selective data to be read from a single tag.
• Collective or selective data to be read from multiple tags without
requiring sorting or unpacking.
• Classes of tags to be filtered according to user-defined criteria.
This technology employs a superior interrogation feature that enables
applications to uniquely identify all tags in the scan field, without
misidentification or identifying the same tag multiple times.
It also uses a robust protocol that maintains a uniform per-tag scan time,
regardless of the number of tags in the scan field. The protocol provides
a flexible software application interface that can be customized to the
specific needs of particular industries and markets.
These unparalleled capabilities make our system an ideal solution for
logistics and warehousing, automatic sortation, pallet tracking, and anti-
diversion/anti-counterfeiting applications.

U519 InstaScan Scanner
The U519 scanner is designed for applications or configurations that
require the scanner to be a considerable distance from the tags, or where
numerous tags are required to be read simultaneously.
The scanner provides nine coaxial connectors for supporting up to nine
external antennas. Each antenna plugs into its own connector on the
rear panel of the scanner.
