1 Introduction
The Savi GateReader 410K is intended for use in applications
where short»range, directed tag communications are
required, such as at gates, checkpoints, and other portals.
Using the Savi GateReader as part of the Savi System, you
can perform vehicle tracking, tag collections, and data
exchanges with tags,
Savi System
The Savi System uses state-of-the-art wireless technology to
monitor, track, and locate assets in complex commercial,
industrial and military environments.
The system comprises tags (also called transponders),
interrogators (also called readers), RF Relays or RF Links,
and a computer with RFID management software installed.
Tags can store, transmit, and receive data and commands
from interrogators, or can initiate communication when
triggered by sensors.
SaviTags and SaviReaders communicate through Savi’s
proprietary radio communications protocol called Batch
Collection.® To gather asset information, collection
commands are either relayed to tags from the computer,
through fixed or transportable interrogators, or issued
directly by the operator from hand-held readers.
Please see Appendix A, "Savi System Description,” for a
more complete description of the system and its components

RFID Management Software
To communicate with Savi GateReaders, use one of these
Savi software packages for RFID system management:
. Savi Asset Manager, version 20
Savi Asset Manager software is used for wide area track-
ing to control and monitor Savi System components. It
has a graphical user interface for ease-of-use when sched—
uling automated events or exporting tag collection data to
your other business systems.
- Savi Retriever, version 2.0
Savi Retriever software operates fully unattended, collect-
ing and forwarding asset data from multiple sites to a cen-
tral business system.
GateReader Description
The Savi CateReader is used to track the movement of con-
tainers, vehicles, and other assets as they enter or leave a
chokepoint or gate. The Savi GateReader 410K can communi-
cate with tags in motion, and with multiple tags simulta-
neously. The GateReader also has the ability to distinguish
between tags travelling in opposite directions along adjacent
lanes.
The Savi GateReader operates at dual frequencies:
433.92 MHz for normal tag communications, and 2.44 GHz
for wakeup signals. The GaleReader uses the Echelon Lon-
WorksTM network and is designed to communicate optimally
with the SaviTag 410. Its power source can be 85 to 264 Vac.

GateReader Components
The Savi GateReader 410K consists of four primary compo-
nents:
- control panel
0 RF unit
‘ primary and secondary wakeup antennas
. motion sensor
Central Panel
The control panel contains a microprocessor for controlling
all of the GateReader components, memory for data buffer~
ing, a LonWorks network interface, an AC adapter and DC
regulator that provide power to all components, and a termi-
nal block to connect wiring for power, the RF unit, and one or
more antennas.
RF Unit
The RF unit consists of a 433.92 MHz receiver, a 433.92 MHz
transmitter, and an antenna. Once a tag (or tags) receives a
wakeup signal from the wakeup antennas, the RF unit then
communicates with the tag. transmitting data back to the
host computer through the control panel‘s LonWorks net—
work interface.
Wakeup Antennas
There are two types of wakeup antennas for the GateReader:
primary and secondary. The primary wakeup antenna con-
nects to the control panel and the motion sensor. it also con
trols, and supplies power to, the secondary wakeup antenna.
Each GateReader may have up to two sets of primary and
secondary wakeup antennas, The wakeup antennas send a
m1 Gmkuln 4101? huh/ll”!!! Evil- I -3
( ( ( ( Sun-Ruin filter/[Ibo
2.44 CHz RF signal to tags to wake them up. The tags then
transmit data using a 433.92 MHz signal that is received by
the RF unit.
Motion Sensor
The mot-run sensor detects oncoming vehicles and then trig-
gers the activation of the primary and secondary wakeup
antennas.
Network Communications
The Savi Gate-Reader 410K supports two types of network
protocols: Echelon‘s LonWorks network and RS—232.
Communications to and from the Savi GatEReader are princi-
pally accomplished with the Echelon LonWorks network
protocol. The LonWorks network is a robust network proto-
col designed for industrial applications. The LonWorks net-
work is used for communication with tags, sensors, other
readers, and the host computer. Savi GateReader also sup-
ports poinHo—point or point-tOAmulti-point communication
via radio frequency modem.
Both incoming and outgoing LonWorlG ports are provided
for network communication when the Savi GateReader is
daisy—chained with other interrogators in an installation.
An RS-232 port is also provided (or diagnostics using appro-
priate diagnostic software and for downloading buffered
data.
Tag Communications
The Savi GateReader communicates with SaviTag 410 model
tags, and has the ability to transfer data with tags travelling
up to 25 miles per hour.
1-4
Gallkulu Burripliu ) ) )
The Savi GateReader is a dual-frequency device: it uses
433,92 MHz signals to communicate with tags, but uses a
2.44 GHz wakeup signal when a tag approaches. When the
vehicle sensor detects motion, it triggers activation of the
gate controller. The gate controller then activates the wakeup
antennas to send a wakeup signal (244 GHz) to the
approaching tags so that the controller can begin collecting
tag data (43392 MHz).
The range for the 2.44 GHz wakeup signal is 20 to 50 feet
from the wakeup antenna. The range for the 433 MHz signal
is approximately 200 feet from the transmitter to a line—of—
sight tag (assumes no obstructions),

Installing the Savi GaleReader 410K takes place in four major
steps:
- mount, configure, and wire the control panel in a NEMA-
rated enclosure (Chapter 2, ”Configurationl
- position the CateReader components (control panel, RF
unit, primary and secondary wakeup antennas, and
motion sensor) for efficient communication (”Positioning
Savi GateReader Components" on page 3-9)
' connect power and network cables and turn on power
("Connecting Savi GateReader Devices" on page 3-13)
- verify communication between the Savi GaleReader and
the host computer ("Verifying Savi GateReader Commu-
nication" on page 3417)
I-é
2 Configuration
This chapter describes the mounting placement and wiring
configuration of the control panel in a NEMA-rated enclo-
sure. It also describes how to install ferrite filters on all power
and network cables.
Mounting the Control Panel
The control panel is mounted inside a NEMA-rated water-
tight enclosure. Figure 21 shows the dimensions of the con-
trol panel and the location of the four mounting holes.
Enclosures such as Hoffman catalog number U-U605025 can
be used that include space to mount AC outlets and support-
ing hardware. (A fan and heater powered from the source AC
maintain operating temperatures within 1e enclosure.)

3 Installation
This chapter describes the balance of the installation process:
- positioning the Savi GateReader components (control
panel, RF unit, primary and secondary wakeup antennas,
and motion sensor) in different configuration
- connecting power and network cables, and turning on
power
- testing communication between the Savi GateReader and
the host computer
Configuration Overview
Three standard configurations are used when installing a
Savi GateReader in the field:
- five-pole configuration for monitoring two-way vehicle
traffic moving faster than ten miles per hour.
- fourvpole configuration for monitoring two-way vehicle
traffic moving slower than ten miles per hourt
- two-pole configuration for monitoring primarily one-way
vehicle traffic moving slower than ten miles per hour.

ve-Pole Configuration
The five-pole configuration requires site preparation, posi-
tioning one control panel, one RF unit, two motion sensors,
two primary wakeup antennas, and two secondary wakeup
antennas, and then connecting network cables and the power
supply.
Site Preyaration
Before installing Savi GateReader components and network
connections, some site preparation is necessary. First, con-
duct a site survey and draft installation plans to anticipate
the configuration of all devices. Use the positioning recom-
mendations in this manual wherever possible.
Once the plan is in place, install mounting poles, under—
ground conduit, and NEMA enclosures according to the
plan, and in accordance with all safety and legal require-
ments, Other site preparation considerations include, but are
not limited to, supplying power, providing telephone con-
nections, and installing power safety or monitoring devices.
Configuration
Place a ZO-foot to 35-foot pole 10 feet from the edge of the
road Install the control panel and RF unit (in a NEMA enclo-
sure) on this pole.
On one side of this pole, place a 22-foot pole that is 32 feet
from the it and parallel to the road, Install a secondary
wakeup antenna on this pole.
On the other side of the pole with the control panel, place an
ll-foot pole that is 32 feet from it and parallel to the road.

Connections
For the Savi CateReader to function as a single unit, its com-
ponents need to be connected together with the appropriate
cables.

Connect the control panel to the primary wakeup antenna
using Savi-supplied network cable. Connect the primary
wakeup antenna to both the secondary wakeup antenna and
the motion sensor(s) to link the components of the Savi
GateReader. Run the cables through underground conduits
to protect them from damage.
Adequate site preparation is critical since the conduit
between the primary and secondary wakeup antennas typi-
cally must be installed to run underground, beneath the road
or tracks.
Power
The control panel requires 86 to 264 VAC power. The internal
AC adapter and DC regulator supply power to all the com-
ponents, including the motion sensor.
Four—Pole Configuration
The four-pole configuration requires site preparation, posi-
tioning one control panel, one RF unit, two motion sensors,
two primary wakeup antennas, and two secondary wakeup
antennas, and then connecting network cables and the power
supply.

Monitoring Bi-directional Lanes or Tracks
The planning and configuration for monitoring a road or rail?
road tracks with bi-directional traffic are the same as for
monitoring a single lane, except that an additional motion
sensor and two additional wakeup antennas are required to
track tags approaching from the other direction.
Monitoring Split [ones or Tracks
The configuration for monitoring split lanes is similar to
monitoring a single direction lane. Each direction requires a
motion sensor monitor and two antennas, primary and sec-
ondary, one on each side of the road. Position a single con-
troller centrally between the two lanes.

Positioning Savi GateReader Components
Savi has tested each component to determine its ideal posi—
tion relative to oncoming vehicles, tags, and other devices.
Whenever possible, follow Savi recommendations Exactly for
positioning reader components, varying the measurements
by no more than 2 feet from the recommended heights or dis-
tances.
Contact your Savi customer service representative, at Savi
technical support, if you find that you cannot exactly match
the configuration but would like to confirm that a similar
arrangement still works effectively.
Note
Ta prevent draining the tag battery, do not park a vehicle cuntm’n-
ing a tag within 5Dfeet ufthe primary ur secondary (makeup)

Positioning the RF Unit
The height of the 433 MHz RF unit is critical to the proper
functioning of the Savi GateReaden It must be high enough
to detect tags on the far side of a vehicle or train.
Mount the RF unit:
- in the center of the Savi GateReader array
- 20—35 feet above the surface of the road or tracks
- with the face cover of the RF unit vertical, parallel to the
pole, as shown in Figure 3-4

Each set at primary and secondary wakeup antennas typi-
cally monitors a single direction of oncoming traffic.
Figure 35 shows, when monitoring Iii—directional lanes, the
configuration alters slightly to accommodate the additional
traffic direction. For a bi—directiona] lane, it is very important
to:
- Raise the position of the secondary wakeup antenna to a
height of 20 feet so that it can "look over” traffic from the
direction it is not monitoring, as shown in Figure 3-5,
- Angle the secondary wakeup antenna so that the face is
tilted slightly downward, at about a 30 degree angle.

Positioning the Motion Sensor
The motion sensor is generally mounted on the same pole (or
building) as the primary wakeup antenna. Securely mount
the motion sensor so that its position won't change. If the
position (angle) of the motion sensor changes, it affects the
ability of the Savi GateReader to function properly.
Position the motion sensor:
~ directly below the primary wakeup antenna, at a height of
9 feet
- with the motion sensor’s direction of aim angled 60
degrees toward oncoming traffic, as shown in Figure 3-7
- with the bottom of the motion sensor parallel to the
ground; in other words, no "tilt” is required in the posi-
tion of the motion sensor

Connecting Savi GaieReader Devices
Once you have positioned and mounted the Savi GateReader
devices] you can connect the network and data cables. Savi
recommends running all data and network cables through
weatherproof conduits, either underground, or above
ground attached to the mounting pole. Make sure to install
conduits for all connecting cables according to the initial site
installation plan and current safety and legal procedures,
Because network and data cables run through parallel con—
duits with the power cables, you can perform this step simul~
tanecusly for both sets of connections.

Verifying Savi GaieReader Communication
To confirm that a Savi GateReader is installed and function-
ing correctly, it is necessary to verify that the computer can
communicate with the Savi GateReader, and that the Savi
GateReader is able to collect tags.
Verification Procedures
Follow these procedures to verify Savi CateReader commu—
nica tion:
1‘ Using a compu ter with a test program installed, locate the
Savi GateReader ID,
Some software applications, such as Savi Asset Manager,
detect the presence of the Savi GateReader automatically.

( ( ( [ Vlrlfylng sm 6.1mm: emu-mum
In this case, simply open the software application and
check to see that the Savi GateReader is listed in the net-
work hierarchy (node tree). Its appearance in the list con-
firms that the device has been detected.
2. Verify that the Savi GateReadeI is able to communicate
with a tag by using a test tag and, using the software, per-
forming a sample tag collect-ion
Refer to the reference material accompanying the test pro-
gram software for specific instructions for performing the
above functions. When these procedures have been com-
pleted/ the Savi GateReader is installed and operational.
Initial Equipment Verification
The control panel contains four LEDs that indicate when cer—
tain components are functioning. Three are on the diagnostic
module; one is on the DC converter:
Figure 3-10 shows the LEDs on the LED diagnostic module.
The green LED begins flashing once per second ten seconds
after initialization, indicating that the firmware is operating
normally. A lit red LED indicates one of the motion sensors
was triggered. A lit yellow LED indicates at least one tag was
collected through the RF unit,

4 Maintenance
///R\
With minimal care, a Savi GateReader should perform flaw-
lessly. However, in the event that a problem with a Savi
GateReader occurs, this chapter should help you fix it.
Maintenance
Saw GateReaders are designed to be maintenancefree. They
are manufachired with the highest-quality components and
are thoroughly tested before delivery.
Self-Maintenance Functions
The Savi GateReader has two self—maintenance functions that
operators should be familiar with. The first is an automatic
”reset" function. The gate reader resets itself if it detects
power fluctuations or other disturbances that disrupt its nor—
mal operations. The gate reader can also be reset manually by
disconnecting and d1en reconnecting the power source.
The second self-maintenance function monitors the status of
cable connections between all of the reader components. The
gate controller continuously polls the cable connections. If it
detects a cable disconnect, it reports the problem to the host
system.

A Savi System
Description
The Savi System uses state—ot—the—art wireless technology to
monitor, track, and locate assets and to remotely control
operations in complex commercial, industrial, and military
environments.
Savi System
The system comprises tags (also called transponders), read—
ers (also called interrogators), RF relays or links, integrated
products, and a computer with controlling software installed
Tags can store, transmit, and receive data and commands
from interrogators, or when triggered by sensors SaviTags
and SaviReaders communicate through a proprietary radio
communications protocol, Savi Enhanced Batch Collect-ion?M
To gather asset information, collection commands are either
relayed from the computer to tags through SaviReaders or
Savi GateReaders, or issued directly by operators from Savi
MobileReadersr
The Savi Enhanced Batch Collection Systemm (EBCS) proto-
col lets each interrogator maintain communications with all
tags that lie Within its radio "micro-cell," while providing
additional security and advanced collection support A
SaviReader can store data from all the tags within its radio
range and can relay the data to the system operator either by
real—time command or on a pre-programmed schedule. A
Savi GateReader can support up to four antennas, reading
tags in motion and discriminating between bi-directional

lanes. Operators can use a Savi MobileReader to perform col—
lections and exchange data with the tags wherever installing
SaviReaders is not practical or where portability is desired,
Savi RFlD System Solutions
Savi offers two complete RFID system solutions that include
the necessary hardware and software components required
to manage complex asset tracking: the Savi InsideTRAK'm
system and the Savi Yard Management System”.
Savi’s InsideTRAK system is a commercial, off-the-shelf
RFI'D solution that allows users to track, monitor, and locate
readily accessible capital assets. The system includes a
SaViTag 310 which attaches to equipment so that it can be
instantly located as it moves through a facility. The system
improves logistics management and deters theft of high-cost
capital assets.
Savi Yard Management System is a commercial RFlD system
that automates data collection and task assignment, from
gate checkin and parking, to dock assignment and hostler
operations. The system is controlled by Savi Asset Manager
software with additional Gate, Dock and Yard application
modules.
Savi SoftWare and Integrated Products
Savi System software and integrated products control the
RFID hardware, either individually or in a network These

Savr Asset Manager monitors and controls Savi RFID compo
nents, collecting and disbursing data as needed for asset
management and tracking. It is preinstalled in a desktop
computer with a 17-inch monitor. Asset Manager stores col-
lected data in its local, relational database. It exports the data
to your main SQL database or file system, either on demand
or on a convenient schedule. It uses visual maps to help you
control which physical areas are to be collected. You can col—
lect information from any area on a regular schedule of your
choice Asset Manager also includes a graphical user inter-
face (GUI) to simplify your control tasks; you can close the
GUI and still leave the Asset Manager able to run scheduled
events. Savi Asset Manager communicates with a variety of
active and passive tags and readers through a modern, a
Saeret network, or a LonWorks networkr
Savi Retriever automates the collection and forwarding of
asset data. It uses a network of Savi interrogators to retrieve
data from tags. It then forwards the collected information
through a modem, local area network, or satellite transceiver
to a central information system, thus allowing assets to be
monitored and tracked at multiple sites. Once configured, all
system functions are automated for unattended operation.
The Savi Tools program lets you diagnose, troubleshoot, and
test Savi hardware capability. Savi Tools offers low-level con-
trol of Savi System hardware components in an easy-to-use
graphical user interface. With Savi Tools you can manage and
fine—tune devices, collect data, define settings, and perform
detailed system and network troubleshooting.
Savi Docking Stations write data directly into the memory of
SaviTags, cutting the time required to initiate a new tag or
update an existing one. The Savi Docking Station connects
directly to the SaviTag through a four-pin connector in the
sliding dock, and connects to the computer through a stan—
dard RS-232 cable. The companion Windows-compatible
software program lets you copy data files from the computer
to tags or read data from tags, either to the screen or to com-
puter files. You can process tags one at a time or in batches,
through a file that associates tag ID numbers with data files.

Savi RFID HardWare Components
Tags are small, radio transceivers that can store user-defined
data in nonvolatile, read/write memory, and can be moni-
tored and controlled by other devices. Active tags contain
their own power source to generate a radio signal. Passive
tags receive their power from an interrogator by radio fre-
quency transmission.
Tags are normally in an energy—conserving "sleep” mode
until reception of a wake-up command from an interrogator
Each tag makes a distinctive beeping noise on command
from an interrogator, thereby making individual tags easy to
locate and identity.
Reader, or interrogators, are electronic devices that send and
receive signals from tags, Readers include a microprocessor
to verify, decode, and route data for transmission to a host
system, usually a computer with appropriate RFID manage-
ment software installed
The frequency of a reader's transmission determines its
range and its ability to communicate with tags. An antenna,
or multiple antennas, sends and receives transmissions The
antenna is either enclosed with the reader, or can be housed
separately.
