Chapter 1
Introduction
he scanners and Dura-labels 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.
These systems consist of Dura-labels that are designed to store
information under extremely harsh environments without requiring
a battery and scanners capable of reading the Dura-labels.
Communications between the scanner and Dura-label 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 Dura-label, may be determined by your
application.

Advantages
Data-gathering systems such as bar code readers and conventional
Radio Frequency Identification products 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 InstaScan and Dura-label to
conduct ongoing two-way communications that are not
restricted by line-of-sight constraints.
Figure 1. Interactive Identification Technology
Page 3
This unique capability allows:
Collective or selective data to be read from a single
Dura-label.
Collective or selective data to be read from multiple
Dura-label without requiring sorting or unpacking.
Classes of Dura-label to be filtered according to user-
defined criteria.
This technology employs a superior interrogation feature that
enables applications to uniquely identify all Dura-label in the
scan field, without misidentification or identifying the same
Dura-label multiple times.
It also uses a robust protocol that maintains a uniform per-Dura-
label scan time, regardless of the number of Dura-labels 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 asset and document management, inventory control,
ticketing, and other high-volume applications and
environments.

S556 InstaScan Scanner
The S556 InstaScan Scanner is designed for applications or
configurations that require the scanner to be a considerable
distance from Dura-labels, or where a high volume of Dura-
labels are required to be read simultaneously. Conveyor Belt
applications are ideally suited to the scanner.
The scanner provides six pairs of coaxial connectors for
supporting up to six external antennas. Each antenna plugs into
its own set of connectors on the back panel of the scanner.
Figure 2 shows the S556 InstaScan Scanner.

Figure 4. Antenna Connections
Page 11
Placing the Antenna
Antenna placement is critical to ensuring that information is
transmitted to and from Dura-labels accurately. Observe the
following guidelines when placing the antenna:
Locate the antenna away from metal objects, microwave
ovens, and other devices that may induce radio
frequency interference. In addition, make sure there are
no metallic surfaces between, or in relative proximity to,
the InstaScan and Dura-label. For additional placement
considerations, refer to “RF Communications” on page
19.
When reading, the InstaScan should be placed no more than 50
inches from the objects bearing the Dura-labels.
! Dura-labels must reside within the scan field for at least 10
milliseconds for information to be retrieved from them.
Page 12
Connecting to a PC Serial Port
The scanner has a 9-pin female RS-232 connector that connects to
a serial port or RS-232 connector on an IBM or compatible
personal computer. The serial port can operate at 2,400 bps or
19,200 bps.

Page 17
Installing Dura-labels
Dura-labels have a diminutive form factor that allows them to be
installed in areas that cannot accommodate conventional RF
tags. In addition, Dura-labels can communicate with the
InstaScan without having to be in the line-of-sight. This unique
combination provides tremendous flexibility when determining
a location for placing Dura-labels.
When considering locations for installing Dura-labels, make sure
they are within 50 inches of the InstaScan antenna for at least 10
milliseconds, so data can be read from the Dura-label. Avoid
locations where metal or water is present because radio-
frequency communication does not penetrate metal and is
absorbed by water.
Reading Information from your Dura-labels
Once you have installed your Dura-labels, and have set-up your
InstaScan system, you are ready to begin.
Insert the Software Development Disk into you A: drive. Turn
your InstaScan power on. Type:
cd \tools
Then type the following command:
A: READ_ID /w 2
This will begin the “READ_ID” program which will display the
information programmed into Memory Word 2 from the Dura-
labels that pass through the scanner field. This memory location
contains your Dura-labels’ unique serial number or “ID”.
This program will continually read the unique serial numbers
from any labels that pass within 50 inches of the InstaScan.
Page 18
Loading Your Application
After you install your system according to the instructions in this
chapter, you can load your application and begin reading
information from the Dura-labels. Your application will
determine the amount of interaction you have with the InstaScan
Scanner and Dura-labels.
! If you will be developing applications designed to interface to your
system, refer to the Software Development Disk for programming
information.

Chapter 3
RF
Communications
n general, devices that communicate using radio
frequency, such as your system , can be sensitive to signal
interference and signal attenuation. This chapter provides
tips for optimizing radio-frequency (RF) communications with
your InstaScan and Dura-label.
Topics in this chapter include:
Signal interference see page 20.
Signal attenuation see page 21.
Optimizing performance see page 22.
I
Page 20
Signal Interference
Signal interference is RF signals that interfere with the
information being exchanged between the Dura-label and the
InstaScan. Signal interference can severely diminish the
Scanner’s ability to read information from the Dura-labels. The
Activity LED on the InstaScan flickers constantly if the InstaScan
detects signal interference.
The source of the interfering signals may be:
An RF system, such as an RF local-area network (LAN) or
another Interactive Identification system, located close to
your system.
Security gates, garage doors, or similar devices that emit RF
signals.
Appliances such as microwave ovens.
The effects of these noise sources are localized and can be
eliminated by relocating the InstaScan or its antenna.
Your system’s communication capabilities are significantly
reduced when the noise level perceived by the system exceeds
the strength of signals received.
Page 21
Signal Attenuation/Reflections
Signal attenuation is the loss of signal strength that occurs
naturally over distances, but which can also be caused by RF
barriers in the signal path.
Examples of such barriers include:
Enclosed locations that have concrete walls, floors, and
ceilings.
Metal surfaces surrounding the antenna or Dura-label.
Water or other fluids surrounding the antenna or Dura-
label.
Almost every object (furniture, partitions, and people) in the
path of a signal causes some degree of attenuation. The effects
can be minimized by careful antenna placement.
The reflection from metal or metallic surfaces behind the Dura-
label can also affect signal attenuation. In some cases, this may
increase the read distance slightly, while inducing intermittent
“dead” spots within the read field that permit little or no
communication between the InstaScan Scanner and Dura-label.
! Dura-labels with similar orientations, placed within two inches of
each other, will have their read distance diminished by about 40%.
Page 22
Optimizing Performance
While it is not possible to predict how the system will perform in
any given environment, observing the following guidelines will
help optimize performance in your environments and
applications:
Carefully plan the placement of the InstaScan Scanner
antenna.
Consider the environment’s RF characteristics, including
construction materials, office plan (closed or open), and the
presence of windows and ducting. The RF field pattern, and
the reading distance, may be influenced by nearby metal
objects, such as appliances, equipment, metal wall framing,
and wire coat hangers.
Ensure that the InstaScan antenna is not pointed directly at
fluorescent lighting.
Ensure that objects containing Dura-labels are no more than
50 inches from the antenna and remain in the scan field for
at least 10 milliseconds.
To avoid mutual interference when installing more than one
Dura-label in the same object, allow a sufficient distance
between the Dura-label. The maximum interference occurs
when Dura-labels within the same object are within 2 inches
of each other and nearly equidistant from the InstaScan
Scanner antenna.
Never apply chemicals to the Dura-label. Certain chemicals,
such as alcohol, may have little or no effect at room
temperature, but may become corrosive at higher
temperatures.

Page 33
Radio Frequency (RF) exposure requirements for
operators of this device
Operators of this device must have knowledge of their RF exposure conditions in
order for the device to comply with FCC-adopted RF exposure limits for persons
in the “controlled exposure environment”. The average RF exposure for
operators is 5.0 mW/cm2, which requires them to maintain an estimated
separation distance of 22 cm or 8.5” from the transmitter, while in operation.
They should not remain closer than the suggested distance for any continuous 6
minute interval. Holding “Tags” in front of the transmitter for brief moments, at
closer than 8.5” is allowed provided the average exposure in any 6 minute
interval is less than 5.0 mW/cm2. For example, if an operator spends 50% of the
time with his/her hands or body closer than 8.5” to the transmitter while
spending the other 50% of the time at more than 15” away, the allowed RF
exposure limits will be satisfied. Operators should use their own judgment to
limit their exposure to the allowed RF exposure limits with control of exposure
conditions, separation distance from the transmitter, and duration of exposure.
While this device is in operation, nearby persons who have no knowledge of
being in the RF fields of this device should be at least 20” away from the
transmitter in order for this devise to be compliant with the FCC-adopted RF
exposure limits.
Disclaimer
Operation of any radio transmitting equipment, including the Scanner, may
interfere with the functionality of inadequately protected medical devices.
Consult a physician or the manufacturer of the medical device if you have any
questions. Other electronic equipment may also be subject to interference.
