Version Compatibility
As AIM2™ has evolved, enhancements were introduced in a specific version of the hardware,
firmware, or software. If problems are being experienced, or if a specific feature or option is not
available, it may be because the current version of the hardware, firmware, or software being used is
not compatible with another system component, or does not contain the desired feature or option. See
Table 3-1 for a list of version compatibilities.

Developing a Database of Vehicle Records
The Central Controller must be set up and the Fuel Management Software installed in accordance
with the FMPlus User Guide. Particular attention should be given to selecting AIM2™ as the passive
system type so the software will prompt for the correct information as the database is developed. The
chapter covering AIM2™ Software Operations must be followed and all procedures performed to
properly set up the vehicle records needed to program the AIM2™ modules.
If an upgrade is being performed and the software was previously set up for a non-passive system,
the software may be reconfigured to develop vehicle records for an AIM2™ passive system. In the
FMPlus User Guide, refer to System Configuration, Passive System Type. This paragraph will
describe what is necessary to change the program to an AIM2™ passive system program which will
allow for the development of vehicle records for programming AIM2™ modules.
Once developed, the vehicle records for the AIM2™ equipped vehicles are uploaded to the FMU
selected to be the programming FMU. See AIM2™ Programming after Installation.
Selecting the Correct Nozzle Tag
The nozzle tag must fit on the dispenser fueling nozzle. When the nozzle is inserted into the vehicles
fuel tank filler neck, the nozzle tag must be within two inches of the filler neck ring, preferably closer,
or touching, and the two devices should be parallel to each other. Being within 2 inches on one side
and 3 inches on another side will not initiate communications. This alignment has
to be correct to
initiate a fueling transaction. The nozzle tag is programmed with a hose number corresponding to a
specific product. The nozzle tag will mark the transaction with the hose number and corresponding
product pumped during a transaction.
The nozzle tag has no wire connections to the fuel dispenser or vehicle. It is totally independent. This
