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,
