Ground Loop Communications - General Information
A Gasboy FMS equipped with an FPR can be configured to authorize a vehicle for fueling or
for opening a gate using ground loop communications. See C35628 FPR Installation Manual
for additional details.
Fueling with Ground Loop Communication is available with a Gasboy CFN system only.
Ground Loop Communications requires a ground antenna installed in or on the pavement at
the fueling island or gate location. There are three installation options for ground antennas to
meet a variety of site requirements:
• Flush-Mount J-Box
• Direct Buried and Sealed
• Surface Mounted
Vehicles are equipped with a special VM containing Ground Loop Communications circuitry
(C09668). In addition, a G-Ring is attached under the vehicle. For gate applications using
Hose Wire communications, the G-Ring is installed in addition to the T-Ring antenna attached
at the fuel tank opening. See C35699 Vehicle Module Installation Manual for VM and vehicle
antenna ring installation details.
Ground Antenna System Layout
When a Fuel Point-equipped vehicle G-Ring is over or near the ground antenna, the vehicle’s
ID is communicated to the FPR and, if authorized, the pump will automatically be made
available to fuel. The vehicle-to-FPR communications must be maintained during the entire
fueling operation. When the vehicle drives out of the communications range, the pump is shut
off and returned to an idle state, ready for a new transaction. The fueling event is logged and
relevant data stored by the FMS unit.
Fueling a Vehicle Using Fuel Point Ground Antenna System
To fuel using the Gasboy ground loop communications system, the site should meet certain
criteria. The following parameters must be considered:
• Each hose outlet (nozzle position) must be dedicated to only one lane. Lane-oriented
pumping units are recommended (such as Gasboy 9800A and 215A/216A Satellites with
suffix Z or equal).
• One ground antenna per hose outlet.
• Ground antennas are normally aligned with the nozzle position (when stored or hung up).
Successful installation requires the special Fuel Point ground antenna
manufactured by Gasboy and careful attention to the instructions that
follow. Do not try to use the loop detector supplied with the gate
controller or the manufacturer’s entrance loop instructions.
