Health Limits (865 to 875 MHz)

Within the United States, environmental guidelines regulating safe exposure lev­els are issued by the Occupational Safety and Health Administration (OSHA).

Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maxi­mum safe exposure limit of 10 milliwatts per square centimeter (mW/cm
aged over 6 minutes at 865 MHz.

Although not binding, other organizations such as the American National Stan­dards Institute (ANSI) have issued similar guidelines that are more restrictive than
the OSHA limits (ANSI C95.1). ANSI guidelines recommend a maximum safe

Thus, the maximum permissible exposure for general population /uncontrolled
exposure at 865 MHz is 0.58 mW/cm

. The power limit is a six-minute average.

™

4/4800 Multiprotocol
Reader was calculated using a maximum antenna gain of 9.5 dBi, equivalent to
the antenna gain of the internal antenna.

Warning

At 2 W transmitted power and a distance of 19.7 inches (50 cm) from the read er,
the maximum power density calculated was less than 0.58 mW/cm

2

. Install the
reader at least 19.7 inches (50 cm) from the general public. Maintenance per­sonnel must remain at least 9.1 inches (23 cm) from reader when system is oper­ating.

The data confirms that the TransCore Encompass 4/4800 Multiprotocol Reader
effectively meets OSHA requirements and thus does not represent an operating
hazard to either the general public or maintenance personnel.

Health Limits (902 to 928 MHz)

Within the United S tates, environmental guidelines regulatin g safe exposure levels are
issued by the Occupational Safety and Health Administration (OSHA).

Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maximum
safe exposure limit of 10 milliwatts per square centimeter (mW/cm
minutes at 902 MHz.

Although not binding, other organizations such as the American National Standards

. The power limit is a six-minute average.

The RF power density generated by the Encompass 4/4800 Multiprotocol Reader was
calculated using a maximum antenna gain of 9.5 dBi, equivalent to the antenn a gain of
the internal antenna.

Warning

At 2 W transmitted power and a distance of 19.3 inches (49 cm) from the reader , the
maximum power density calculated was less than 0.60 mW/cm

. Install the reader at
least 19.3 inches (49 cm) from the general public. Maintenance personnel must
remain at least 8.66 inches (22 cm) from reader when system is operating.

The data confirms that the TransCore Encompass 4/4800 Multiprotocol Reader effec­tively meets OSHA requirements and thus does not represent an operating hazard to
either the general public or maintenance personnel.

Introduction

This chapter is the introduction to this manual and provides information
pertaining to the audience, organization, document conventions, system
description, and license information for the Encompass™ 4/4800
Multiprotocol Reader System.

This guide provides site planning and testing, installing, and operating instructions for
TransCore’s Encompass 4/4800 Multiprotocol Reader System, a dual-protocol reader
that reads Intellitag®-based eGo protocol and American Trucking Associations
(ATA)/International Or ganization for Standardization (ISO) tag protocols. Before you
begin installing the Encompass 4/4800 Multiprotocol Reader System, TransCore rec­ommends that you read this entire manual.

This document is intended to be used by authorized TransCore Encompass 4/4800
Multiprotocol Reader System dealers, installers, and service personnel. Because the
Encompass 4/4800 Multiprotocol Reader System has no operator- or end-user service­able components or features, no end-user manual or operator guide exists. Once the
system is set up and tested by the authorized installer, Encompass 4/4800 Multiproto­col Reader System operation requires no end-user intervention.

System Guide Organization

Note: TransCore offers the Encompass 4/4800 Multiprotocol Reader in two models:
one with an internal antenna and one that requires connection to an external antenna.
In this system guide, information and instructions for both Encompass 4/4800 Multi­protocol Reader models are presented. Where separate sections dictate, a section
detailing one Encompass 4/4800 Multiprotocol Reader model is followed immediately
with a section detailing the other reader model. In this system guide, the reader with
an internal antenna is listed first. In cases where the information does not warrant a
separate section, the addition of "...or antenna" distinguishes between the Encompass
4/4800 Multiprotocol Reader models.

The Encompass 4/4800 Multiprotocol Reader System is a dual-protocol reader sup­porting the low-cost, high-performance Intellitag® radio frequency identification
(RFID) technology. Intellitag technology provides the capability to read miniature
RFID tags in a myriad of options including rugged, durable, or thin flexible forms
such as the eGo Windshield Sticker Tag. The Encompass 4/4800 Multiprotocol
Reader System also supports legacy transportation applications such as gated toll,
parking, or security gate access and is designed to be compatible with existing
TransCore SmartPass® parking access control applications certified for licensed use.
The Encompass 4/4800 Multiprotocol Reader System supports the TransCore eGo and
TransCore ATA/ISO tag types.

Encompass 4/4800 Multiprotocol Reader System Guide

The Encompass 4/4800 Multiprotocol Reader System is a full-frame high-power unit
that can read both half-frame and full-frame tags. The reader output power can be
adjusted using reader commands.

Reader

The Encompass 4/4800 Multiprotocol Reader System consists of an input/output (I/O)
module, a power supply, a reader logic board (also called a tag decoder), a radio fre­quency (RF) transmitter/receiver (called the RF module), and a patch antenna.

A second version of the Encompass 4/4800 Multiprotocol Reader is designed to be
used with a high-performance external antenna. These Encompass 4/4800 Multiproto­col Reader System components are contained in a highly reliable, compact, and easy­to-install environmentally-sealed package. Figure 1-1 shows the front and side views
of an Encompass 4/4800 Multiprotocol Reader System.

Tags

The Encompass 4/4800 Multiprotocol Reader System has the capability to read the
Intellitag-based eGo Windshield Sticker Tag as well as TransCore ATA protocol and
TransCore ISO-compliant read-only full- and half-frame tags.

How It Works

The Encompass 4/4800 Multiprotocol Reader System directs the RF module to gener­ate an RF signal, which is broadcast through the internal or external antenna. Entering
the Encompass 4/4800 Multiprotocol Reader System’s reading range, a TransCore
RFID tag installed on a vehicle or other object to be tracked adds its programmed
identification information to the signal and reflects the signal back to the Encompass
4/4800 Multiprotocol Reader System. The Encompass 4/4800 Multiprotocol Reader
System receives this modified, or modulated signal, and decodes the tag data carried
by the reflected signal and transmits this data to a local host computer for processing.

Licensing Requirements

An FCC license provides the user with the legal authorization to operate the Encom­pass 4 on the licensed frequencies at the site specified in the license. Only an autho­rized installer or service technician can set the RF frequency of the Encompass 4/4800
Multiprotocol Reader System to the frequency specified in the FCC site license. No
end-user-operated controls exist on the Encompass 4/4800 Multiprotocol Reader Sys­tem.

The FCC license also provides the user with protection and authorization to maintain
the system should any other RFID product be used in the licensed area after the
Encompass 4/4800 equipment is installed.

Users of the Encompass 4/4800 Multiprotocol Reader System in the United States
must obtain a license from the FCC. The authorized frequency band for this product in
the United States is 912.5 to 919 MHz.

The user is responsible for filing the FCC license according to FCC regulations, but
the TransCore dealer will provide assistance and support as necessary to complete
these forms. Forms are available online at the FCC internet site http://www.fcc.gov/
formpage.html. For further information on obtaining the license contact TransCore.
