System Description
SUMMARY
SIRIT’s IDentity Flex Automatic Vehicle Identification (AVI) system is a stand-
alone Radio Frequency Identification (RFID) system which communicates with
SIRIT’s IDentity Flex family of transponders and California Transportation
System Title 21 compliant transponders. The IDentity Flex system provides
positive identification of vehicles equipped with
these transponders to permit hands-free access
control to parking and gated communities as well
as for airport, truck fleet monitoring and highway
tolling applications.
The IDentity Flex Reader System is enclosed in
a weather-resistant enclosure and comprises a
radio frequency (RF) transceiver (the reader)
and a universal input voltage power supply. Each
reader system is capable of servicing four
separate transponder-reading locations, each
equipped with transmit/receive antennas.
Each reading location can be serviced by two
input (detection loops, light curtains) and two
output (gate, signal light) devices connected to
the reader by appropriate shielded cable. Each
of the remote antennas communicates with the
reader system through two 50-Ohm coaxial
cables.
Multiple readers can be networked to provide
coverage of any number of lanes at a given site.
The reader system may be configured for
customized operation by a combination of
externally accessible hardware jumpers and
menu-driven software settings via a dedicated
RS-232 maintenance communication port.

The IDentity Flex system is capable of communicating transponder transaction
activity to variety of established back-end host systems including ASCOM, WPS
and Safehouse via. RS 232, RS 485 and Wiegand interfaces, as well as simply
reporting transponder identification information.
The IDentity Flex Reader can in many situations replace the function of the lane
controller as it has discrete outputs on board that can be used for gate control or
other lane control functions. In addition, the IDentity Flex Reader software
contains a translation table that can be used for transponder identification and
validation. As an example, if at some future point you wanted to add other
IDentity Flex transponder patrons from some other installation into your system it
can be done simply and economically. This would be both convenient and cost
efficient, as patrons would not be required to carry multiple access devices.
OPERATION
The IDentity Flex Automatic Vehicle Identification system is part of an electronic
access system and provides the ability to automatically identify a vehicle, validate
its movement and communicate this information to a lane controller or centralized
management computer.
The SIRIT IDentity Flex system features state-of-the-art electronics, a specially
designed remote
antenna operating at
916.25 MHz and true
versatility in
configuration options.
While the IDentity
Flex system may be
configured in many
ways and no two
installations may be
identical, there is a
certain sequence of
events in operation.
The transponder, or
radio frequency tag,
is placed on the
inside of the vehicle
windshield, (or on the
vehicle’s license plate
with a special
external tag). When a
vehicle passes over a Figure 1.1 – System Operation

detector loop at an entrance or exit, the IDentity Flex reader is armed and begins
to transmit a signal from the antenna in that lane. The vehicle is also now
positioned within the radio beam radiating from an overhead or side-mounted
antenna and the tag receives the wake-up signal.
The tag then reflects back a signal containing its identification number. The
identification signal is received and sent to the host computer for validation and is
compared with tag numbers on a master list kept by the host. If the tag number is
valid, the host opens the gate, for instance.
The same events take place when a vehicle leaves the controlled-access
location and arming and detector loops in the ground may be used as controls.
The host computer maintains an event log containing date and time stamps.
Stand Alone Operation
The IDentity Flex reader is capable of servicing four separate antenna locations.
Each of the four locations are supported by two independent discrete TTL
capable inputs, which may be used for such purposes as vehicle detecting loops
or light curtains. Additionally, each location is also supported by two discrete
outputs which are jumper configurable for either +5VDC or +12 VDC current
limited outputs. These outputs can be used for such purposes as gate vending
control or vehicle stop-and-go light control. Utilizing the ID Flex Windows
software, the reader can be configured for stand alone operation.
Components
IDENTITY FLEX TRANSPONDER FAMILY
The transponders in the IDentity Flex family are small reflective devices designed
for vehicle identification. Each transponder is a battery-operated backscatter
reflective device that communicates the account information stored in an internal
data register of 64 bits when “polled” by the reader system. The transponder is
idle unless in the presence of an RF wake-up signal from a reader on 916.25
MHz.
The IDentity Flex transponder’s wireless link uses comprehensive error detection
methods to ensure a 99.995% accuracy rate even under the most adverse
environmental conditions. Error detection and correction also ensures
information is transferred accurately between the transponder and reader.
The IDentity Flex reader system can communicate with either SIRIT’s IDentity
Flex family of transponders that utilize a Double Phase-Shift Keyed modulation
scheme or CALTRANS (Title 21) readable transponders that utilize a frequency-
shift keyed up-link modulation scheme.

Version 2.3 Page 4
IDentity Flex transponders mounted in vehicles are placed at the top of the front
windshield, behind the rear view mirror. The external mount transponder is
attached to the front license plate of the vehicle. See the section starting on
page 52 for mounting instructions.
IDentity Flex Transponder
The IDentity Flex transponder is equipped with a replaceable 4-year coin cell
battery and a second battery can be added for longer life. The transponder is
attached to the windshield by Velcro™ strips. This allows it to be removed from
the vehicle or locked in a glove box while not in use. The IDentity Flex
transponder is pre-programmed at the factory with a dealer code, facility code, ID
number and manufactured serial number.
Security-Flex (S-Flex) Transponder
The S-Flex transponder is equipped with a 4-year non-replaceable battery and is
attached to the windshield with adhesive strips. The transponder will be
deactivated if it is removed after installation, preventing use in unauthorized
vehicles. Deactivated transponders must be returned to SIRIT for reactivation.
Like the IDentity Flex transponder, the S-Flex is pre-programmed at the factory.
External Mount Transponder
An external mount transponder is preferred in truck fleet monitoring applications
and on certain vehicles that have high metal-oxide content in their windshields.
This transponder is mounted on the front license plate holder. More information
on metal-oxide’s effect on Radio-Frequency devices such as the IDentity Flex
transponders can be found on page 51.
External mount transponders can be read by Title 21 systems and, as such, are
programmed for use with the IDentity Flex system on-site by the dealer.
Mounting instructions can be found on page 53.
IDentity Title 21 (Tolling Application) Transponder
The IDentity Title 21 (T21) transponder can be read by highway toll collection
systems that are compliant with the California Department of Transportation’s
Title 21 open standard. It therefore serves a dual-purpose role in also allowing
access to IDentity Flex system controlled areas. It is mounted inside the
windshield with Velcro™ strips. The Title 21 identification number can be loaded

into the reader look-up table to allow access to facilities utilizing the IDentity Flex
reader.
IDENTITY FLEX READER
SIRIT’s IDentity Flex reader system is a Radio Frequency Identification (RFID)
system that communicates with California Transportation System Title 21
compliant transponders and SIRIT’s IDentity Flex transponder family.
The IDentity Flex reader is mounted within a weather-resistant NEMA 4X rated
enclosure and is comprised of an RF transceiver and a universal input voltage
power supply. Normally the reader and power supply are mounted onto a
supplied backplane which is sized for the locking NEMA enclosure and provides
a tidy tamperproof installation. A 120 VAC 15 Ampere power source is required
and is adequate to operate one transceiver chassis and power supply.
.
Each reader system is capable of servicing up to four separate transponder-
reading locations (read points). Each of the four read points is supported by two
independent discrete TTL capable inputs, which may be used for such purposes
as vehicle detecting loops or light curtains. Additionally, each transponder
reading location is also supported by two discrete outputs which are jumper
configurable for either +5VDC or +12VDC current limited outputs, which may be
used for such purposes as gate vending control or vehicle stop and go light
control. Each of the four read points may be remotely located from the reader by
up to 200’ of coaxial cable, which connects the reader to the remote antennas.
The reader system may be configured for customized operation by a combination
of externally accessible hardware jumpers and menu driven software settings via
the dedicated RS-232 maintenance communication port. Instructions for
configuring these settings start on page 34. The reader is connected to a laptop
computer running an emulation program such as SIRIT’s Identity Flex Windows
software, ProComm™ or Windows® HyperTerminal™ to perform system setups,
configurations and maintenance functions. The maintenance port also functions
as an input for the purpose of updating the tag translation list.
The IDentity Flex system is capable of communicating transponder transaction
activity to a variety of established back-end host systems, as well as simply
reporting transponder identification to the Host. Additionally, each of the four
different transponder reading channels have their own independent Wiegand
protocol output for reporting to back-end systems. The IDentity Flex reader is
compliant with FCC Part 15 and FCC Part 90 rules.
It is important to establish power requirements and location of the IDentity Flex
reader in conjunction with the Pre-Installation Questionnaire. A guide to
establishing the layout of the system begins on page 9. IDentity Flex reader
installation instructions begin on page 26.
