Gasboy Gilbarco Interface Unit - Manual (Page 11)

Gilbarco Interface Unit v2.1 Introduction 3
Gasboy CFN Series
Differences between interface versions 1.2 and 2.0
In version 2.0, the MPD Pro Blender or other models with six fuels on a side are supported.
CRINDs are supported, using the spare RS485/422 port. Current loop port #2 is not used.
Version 2.0 supports a maximum of sixteen fueling positions, while version 1.2 supports 32
fueling positions. In version 1.2 the spare RS485/422 port is not used, while current loop number
2 supports an extra sixteen fueling positions.
Differences between interface versions 2.0 and 2.1
Version 2.1 supports the same equipment as version 2.0, and in addition, supports one GSM,
connected to a serial port.
Version 2.1 supports the six-digit money option in gilbarco pumps. All pumps on an
interface must be configured the same.
Potential problems
Cash/credit buttons and more than two price levels
Pumps with cash/credit select buttons may be used only with price levels 0 through 2. The
combination of cash/credit buttons and many price levels is not workable.
Level 0 must be the same as level 1 for all such pumps at a site, or it must be the same as
level 2 for all such pumps.
Many price levels on multiple hose units
Many price levels on multiple hose units may cause a few customer relations problems at the
site, depending on the prices used. A customer awaiting activation will in some cases see a
number of different prices in quick succession on the main price display, as the interface
downloads new prices to the pump.
MPD, Pro Blender, Salesmaker IV, and so on, without cash/credit select buttons, may be
used with price levels 0 through 5.
Measured totals for blended products not available
Product totals for blended products are maintained as totals per blend, not as totals per blended
primary fuel.
Reconciliation of these totals with tank inventory must be handled by manual methods,
outside the system. A program named BLEND.BIN is part of the software for Site Controller II,
versions 2.0b and later. BLEND.BIN produces a primary fuel report by allocating recorded
amounts of blended fuels back to the primary fuels, based on the intended blend ratio. If you
need BLEND.BIN and it is not in your Site Controller release, check with your sales
representative.
Cash/credit select and Site Controller I
Cash/credit select switches on the pump may not be used with the Site Controller I.
Gallon cutoffs on multiple hose or fuel units
Gallon cutoffs and limits should be set with caution. These are allowed on single-hose pumps,
but not on others. MPD cutoff limits must be made in dollars, as the Gasboy equipment cannot
arrange for volume presets on Gilbarco multi-fuel pumps. The Site Controller uses dollar limits
