Introduction
This manual provides installation and setup instructions for the Syn-Tech Systems, Inc., FuelMaster®
AIM2™ Automotive Information Module (herein referred to as AIM2™) and associated equipment.
These instructions have been prepared for the exclusive use of installation technicians who are
qualified to complete electrical work on vehicular electrical systems. AIM2™ consists of equipment
developed to initiate passive fueling through a FuelMaster®FMU-3500 Fuel Management Unit, or a
FuelMaster®FMU-3535 Passive Mobile Fuel Management Unit.
Passive fueling, as used in this context, is the initiation of a fueling transaction by the AIM2™
equipment without the need for operator input. The fueling customer pulls his/her vehicle up to the fuel
dispenser (or fuel truck), takes the fuel nozzle down from the dispenser, and inserts it into the vehicle
fuel filler neck. This action prompts the AIM2™ equipment in the vehicle to transmit authorization via
RF (radio frequency transmission) to the FuelMaster®FMU-3500/3535 which, in turn, activates the
fueling hose. When complete, the fueling customer returns the nozzle to the dispenser, returns to
his/her vehicle and drives away. The FMU-3500/3535 records the fuel transaction and stores the
fueling information until downloaded by the FuelMaster®Fuel Management Software operator.
Purpose
FuelMaster®fuel accounting and control provides Syn-Tech’s customers with a means to control
access to metered products at self-service service stations, and to account for and invoice for the
dispensed products. FuelMaster®accomplishes this with security from unauthorized user access while
maintaining complete accountability of each transaction as it occurs. FuelMaster®passive fueling
provides for secure, accountable control of fuel dispensing without direct user access of the fuel
management system. Transaction data is compiled after downloading data to a central accounting
office hundreds, or thousands of miles remote from the servicing operations.

Safety Precautions and Corrective Actions
NFPA 70, the National Electrical Codes (NEC), define a fuel dispensing site as a hazardous location
and contains guidelines for the installation and operation of any equipment in such a location. NFPA
30, Flammable and Combustible Liquids Code, contains guidelines for electrical equipment and
installations in areas where Class I liquids are stored or handled, and where Class II or Class III
liquids may be stored at or above their flash points. The installer must be knowledgeable of these
and any other applicable safety codes and standards. All FuelMaster®passive fueling equipment
complies with applicable federal, state, and local safety codes and standards.
This manual makes recommendations for commercially available equipment and materials that are
required to complete an installation. Trade names and part numbers are also referenced to cite
products that have been tested and known to be serviceable with passive fueling equipment.
Modification of the equipment provided, substitution of any material requirements, or any deviation
from these installation instructions must comply with all applicable safety codes and standards.
Use the following guidelines during installation and maintenance to help protect your passive fueling
equipment from potential damage and ensure your own personal safety:
Protecting Against Electrostatic Discharge
Static electricity can harm delicate AIM2™ components. To prevent static damage, discharge static
electricity from your body by touching an unpainted metal surface before you touch any AIM2™
electronic components.
As you continue to work with AIM2™, periodically touch an unpainted metal surface to remove any
accumulated static charge. Use of a wrist-grounding strap is highly recommended.
The following steps should also be taken to prevent damage from electrostatic discharge (ESD):
•Keep a static-sensitive component in its antistatic packing material until ready for use. Just before
unwrapping the antistatic packaging, discharge accumulated static electricity by touching an
unpainted metal surface.
•Transport sensitive components in antistatic containers or packaging.
•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
Correcting RF Interference
This equipment generates, uses and can radiate radio frequency energy and if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning off and on the equipment, the user is encouraged to try to correct the
interference by one or more of the following measures:
•Reorient or relocate the radio/TV’s receiving antenna;
•Increase the separation between the equipment and the radio/TV’s receiver;

9
•Connect the equipment into an outlet on a circuit different from that to which the radio/TV’s receiver
is connected; and,
•Consult the dealer or an experienced radio/TV technician for help.
Certification/Approval
The equipment supplied with AIM2™, FMU-3500, and FMU-3535 is tested and safety certified

SECTION 2
SYSTEM DESCRIPTION
Syn-Tech Systems, Inc. offers a passive fueling version of their world renowned Fuel Management
Unit (FMU). The FuelMaster®Plus FMU-3500 is built on the widely accepted FMU-2500 platform with
the addition of components required to facilitate passive operation. AIM2™ is the trademarked name
of Syn-Tech’s passive fueling system. The name AIM2™ is derived from the principle component of
the system, the second generation Automotive Information Module.
The installation procedures contained herein will only cover the taskings unique to AIM2™ passive
fueling, and any differences as they apply to FMU and software installations. Basic FMU installation
must be referred to the FMU-2500 Installation Manual. Software setup and operation must be
referred to the FMPlus User Guide.
FuelMaster®Passive Fueling
FuelMaster®passive fueling provides for secure, accountable control of fuel dispensing without the
need for user access of the FMU.
Vehicles (or other equipment items) and fuel island dispensers are fitted with passive fueling
equipment, and an FMU-3500 is installed to authorize and record fueling. The FMU-3500 links the
vehicle to the dispenser. Options are available to upgrade other existing models of FMUs to the FMU-
3500 configuration. It may not be necessary to purchase new FMUs to acquire passive fueling.
Typical Fueling Transaction:Automation and control are totally transparent to the fueling
customer in a typical AIM2™ fueling transaction. The fueling customer drives an AIM2™ equipped
vehicle up to the fuel dispenser, takes the fueling hose down, turns on the dispenser, inserts the fuel
nozzle into the fuel tank filler neck, and pumps fuel. When fueling is complete, the customer removes
the nozzle, turns off the dispenser, hangs the nozzle up, then returns to the vehicle and drives away.
Through this procedure, the passive fueling system has authorized the transaction, then recorded the
vehicle, quantity, product, hose, date, time, and odometer/chronometer reading at the time of the
transaction, and accomplished all this without user access of the FMU. Table 2-1 reflects additional
data which may be recovered by AIM2™ through an OBD II (onboard diagnostics) connection.
Availability of this data will be dependent upon the vehicle and its ability to generate the data.
Light/Heavy Duty is primarily to differentiate between the types of OBD connections available. As
shown in the table, Heavy Duty vehicles may generate more data.
Insertion of the fuel nozzle into the vehicle’s filler neck triggers the AIM2™ module (vehicle
transceiver) to send authorization information to the FMU. Upon receipt of an authorized input, the
FMU turns on the selected dispenser hose and records the fuel quantity pumped into the vehicle.
Removing the fuel nozzle from the vehicle’s filler neck ends the transaction. Fueling cannot be
resumed without reinserting the nozzle into an AIM2™ equipped vehicle, or by the user accessing the
FMU with an alternate access device (Prokee®, Smartcard, credit card) or keyless configured entry.
Automated transactions may only be initiated by vehicles or access devices with the same Site
Signature (unique customer identifier) as the FMU controlling the fuel dispensers.
Passive fueling transactions may also record user identification through keypad entry at the FMU, or
by passing a proximity card across the optional Proximity Card Reader.

Installation Requirements:The normal sequence of events to complete the installation of an
AIM2™ fueling system entails software installation, FMU installation, then AIM2™ module installation
and programming. AIM2™ programming is required, but cannot be performed until the software is
installed and databases are developed, the FMU is installed, and the AIM2™ modules are installed in
the vehicles.
Although not absolutely required, Syn-Tech Systems recommends installation of the FMU-3500 and
Central Controller initially for use with a direct access device such as a Prokee®, Smartcard, credit
card, or Keyless entry. This permits the development of the required databases, and installation of
the AIM2™ modules in preparation for passive fueling. As the AIM2™ modules are installed, the
other interfaces will already be in place to bring passive fueling online.
Components of a Passive Fueling System
FMU-3500 and FMU Upgrades. The FMU-3500 is an FMU-2500 equipped for passive
fueling. FMUs of other configurations may be upgraded to FMU-3500 to gain passive fueling
capabilities. The FMU-3500 will have a backup function for user access with a Prokee®,
Smartcard, magstripe card, or through Keyless transaction entry. Features which make an FMU-
3500 compatible with passive fueling are:
Power LED
Channel A Receive LED
Channel A Transmit LED
Firmware Version
Channel B Receive LED
Channel B Transmit LED
Channel A Channel B
Figure 2-1. FMU Radio Board (FRB)
•An FMU Radio Board (FRB) which functions as a transceiver to receive inputs from, and send
programming information to AIM2™ equipped vehicles and equipment. The FRB includes A

16
and B channel outputs/inputs, and five LEDs: a red, steady Power LED, and four green,
flashing transmit/receive LEDs as shown in Figure 2-1.
•Two 926 MHz antennas for receiving RF transmissions from the AIM2™ module. These
antennas may be attached to the FMU, or external (remote) antennas may be installed to
ensure best possible RF coverage. The antennas are connected internally to the FRB.
External antennas may be necessary when an FMU is physically separated from line-of-sight
with the fueling vehicles. The external antennas may be used to restore line-of-sight to the
fueling vehicles. External antennas installed under a roof or higher than FMU height should be
installed horizontally instead of vertically. The two antennas should be spaced 8 inches (or in
multiples of 8 inches) apart.
•Quad UART board to control a second FRB when a secondary application requiring directional
antennas (for Access Point) is needed.
•A Compact Flash Card for operating and programming memory. It is absolutely necessary for
FMU-3500 functions. The compact flash card is now standard in all FMU-2500 series units.
Some older FMU-2500 units being upgraded to FMU-3500 may require a newer revision
mainboard to accept and correctly read compact flash cards.
FMU-3535 Passive Mobile. The FMU-3535 Passive Mobile is an FMU-3500 adapted for
mobile use on tanker trucks. The FMU-3535 provides a mobile capability for fueling AIM2™
equipped vehicles or equipment which may not be able to return to a service station for fueling.
Passive Mobile installations are covered in a separate installation manual.
Automotive Information Module. The Automotive Information Module (see Figure 2-2) is
an intrinsically safe vehicle mounted transceiver/computer which stores vehicle information and
communicates with the FMU to authorize fueling hoses and receive programming information. The
standard module (part number 941B0420A) has an internal antenna and is suitable for most
applications. When necessary, an external antenna may be installed and connected to part
number 941B0420B AIM2™ modules. 941B0420A modules do not have external antenna
connections. 941B0420B modules do not have internal antennas. External dimensions of both
modules are approximately 5-5/8 inch long x 2-3/8 inch wide x 1 inch high. Acceptable input
power is 12 VDC to 42 VDC. AIM2™ modules draw 0.4 amps when active, and 0.0134 amps in
sleep mode. The AIM2™ module is designed for operation in temperatures ranging from -60 to
+140 degrees F.

AIM2™ modules may receive odometer and chronometer inputs through an OBD II connection, or
through analog speed sensor and analog chronometer inputs. Power for the AIM2™ module may
be supplied either directly through the OBD II connection, or through an analog speed sensor
cable. The chronometer cable does not make power connections.
Amber, Yellow, Green, and Red indicator lights (LEDs) are built into the center top surface of the
AIM2™ module for feedback of operating and programming conditions. These LEDs must remain
visible after installation for testing and troubleshooting.
AIM2™ modules go to “sleep” (become idle and operate on reduced input power) 2 minutes after
the vehicle ignition is turned off or, if within communications range of an active FMU-3500, 15
minutes after the vehicle ignition is turned off. The module must be “wakened” before fueling may
occur. Turning on the vehicle ignition or starting the engine will waken the module.
AIM2™ modules have three possible interface settings or states: NONE, OBD, or SPEED
SENSOR. NONE is the default. When the module is set to NONE, it will not go to sleep. OBD and
SPEED SENSOR indicate an OBD or analog connection. When connected to an OBD connector,
an AIM2™ module will detect OBD and change state as soon as the vehicle is turned on. When
connected to a SPEED SENSOR, the AIM2™ module will not change state until the vehicle starts
moving. Reefers require the engine to be started after installation to change state.
AIM2™ Module External Antenna. The AIM2™ module has to communicate with the FMU
FRB. Some vehicle mounting applications may not readily support communications between the
AIM2™ and FMU. In these instances an external antenna may be mounted on the vehicle and
connected to the AIM2™ module to ensure RF coverage. Syn-Tech has external antenna kits
available with 13 or 20 foot long cables, mount brackets, and the necessary fittings to connect to
AIM2™ modules equipped to accept external antenna connections.
Access Point. An Access Point is a device developed solely to control gate/door/carwash
access or monitor vehicle movement via RF transmission from an AIM2™ equipped vehicle. A full
description and installation procedures for an Access Point may be found in Appendix A to this
manual.
AIM2™ Programming Key. A Prokee®/Smartcard with special application; an AIM2™
Programming Key will only permit programming of an AIM2™ module.
Nozzle Tag (sometimes referred to as Hose Tag). The Nozzle Tag is an intrinsically safe device
installed on the fuel dispenser (or Passive Mobile) fueling nozzle to initiate a passive fueling
transaction. The Nozzle Tag contains an antenna coil and RF/ID chip programmed with a number
to identify the fueling nozzle it is attached to. Unique to FuelMaster®, the Nozzle Tag does not
require a cable routed down or through the fueling hose for power. Nozzle Tags are available in a
variety of sizes and shapes to accommodate most known fuel nozzle types. Figure 2-3 is an
example of a nozzle tag. Table 2-2 is a listing of nozzle tags in production at the time of this
writing. Additional nozzle tags may be developed as the need arises. Table 2-3 is a listing of CV
(constant velocity) boot clamps offered by Syn-Tech Systems to secure the nozzle tag to the fuel
nozzle. Table 2-3 also lists a kit part number which contains the more popular nozzle tags with a
CV boot clamp.
Programming Hose Tag (PHT). A specially programmed nozzle/hose tag used to identify
vehicles when programming. These are identified with an attached label containing a letter (one letter,

18
A through F). Each FMU may be configured to use a single PHT. A PHT is needed to complete the
programming interface between an AIM2™ module and the FMU. PHTs are made from operational
nozzle tags which closely match the application in which they are used.
Figure 2-3. Sample Nozzle Tag
Table 2-2. Nozzle Tag Applications

19
Table 2-3. Nozzle Tag Clamp and Kit Part Numbers
Filler Neck Rings/RFID Interface Module. Like the nozzle tags, filler neck rings contain
an antenna coil and RF/ID chip for communications with the nozzle tag. The filler neck ring has a
48 inch pigtail for connection to the RFID Interface Module (also referred to as Lump Board). Filler
neck rings are available in a variety of sizes for installation on a variety of vehicle fuel tank filler
necks (see Table 2-4 for a breakdown of sizes, profiles, and pigtail lengths). Filler neck rings may
be glued in place with a gasoline and oil-resistant adhesive such as Seal-All from Eclectic
Products, Permatex or 3M Super Weatherstrip adhesive, or Gorilla Glue (for rough surfaces). If
you cannot find one of these adhesives, try to find something with similar properties which is gas
and oil-resistant, and will not damage the rubber surface of the filler neck ring. Lipped filler neck
rings may also be tacked in place with screws if care is taken not to contact the internal coil of the
filler neck ring.
The RFID Interface Module generates the signal for the filler neck ring to communicate to the
nozzle tag. When the nozzle tag is brought close enough to the filler neck ring, information (hose
number) in the nozzle tag is received by the filler neck ring and transmitted through the RFID
Interface Module and RFID Extension Cable to the AIM2™ module. Early variations on the RFID
Interface Module had connectors exiting straight out of the end of the module. Current versions of
the module have connectors positioned at right angles to the module. There are also some newer
variations with clear (instead of black) potting. Figure 2-4 illustrates a sampling of the vehicle
components which complete the connections from the filler neck ring forward to the AIM2™
module.
Connecting Cables.The AIM2™ module receives connections from an assortment of cables
designed for the application. RFID Extension Cables connect between the RFID Interface Module
and AIM2™ module, and are available in 15, 20, 30, 50, and 80 foot lengths. Connections through
the OBD port provide information and power to the AIM2™ module. Figure 2-5 is of an OBD II light
duty connection cable with a pass-thru connector which allows for connection of an OBD
diagnostic tester without disconnecting AIM2™. Other cables are available for other types of OBD
connections.
Cables for analog connections to a speed sensor or chronometer have pigtails for the necessary
connections. Analog chronometer connections do not connect to vehicle power. AIM2™ module
power must be derived from an OBD or speed sensor cable connection.

A chronometer need not be a physical device added to the vehicle/equipment to attain the desired
information. A chronometer input may be as simple as a power source which is only powered
under special circumstances. Engine runtime may be a power source which is only supplying
power when the engine is running; PTO (power takeoff) engage time may be a power source
which is only supplying power when the PTO is engaged. Chronometer inputs may be from as
many as three different sources: through the OBD connection and up to two analog chronometer
inputs, to record vehicle run and idle time, and PTO time.
Cables are available for combining two separate fuel tanks and their filler neck rings into one
AIM2™ module. When this is done, fillups to either tank are recorded. When the transactions are
downloaded into the software, the vehicle record has only one tank record so transactions from
