Gasboy Gilbarco Interface Unit - Manual (Page 10)

2 Introduction Gilbarco Interface Unit v2.1
Gasboy CFN Series
Dual price bar: a price bar that shows two different prices, for instance cash and credit, at the
same time.
Alternating price bar: a price bar that shows two different prices, for instance cash and credit,
alternately. A dual or alternating price bar may sometimes be required, but it restricts options for
pricing at the site where it is used.
When we mention dual price bar in this manual, the remarks apply equally to alternating
price bars.
Price code: a Gasboy code for a single set of prices, one price per method of payment, that may
be applied to a fuel, grade, or product.
Price level: a Gasboy code that distinguishes between the different prices found in one price code
set. Values of price level are associated with tender types as follows: price level 1 is for cash,
price level 2 is for credit. Price level 3 is for debit, levels 4 and 5 for fleet or club cards, while
level 0 is the standard fallback price that appears on the main price display when the pump is
idle. Levels 0 to 5 will appear on the main price display. Additional price levels may also be used,
but will not appear on any price display.
The Gilbarco interface unit
The Gasboy Gilbarco Interface Unit allows a Gasboy Site Controller II to control up to 8 dual or
16 single-sided Gilbarco dispensers. Cash/credit selection switches may be installed on the
pumps, but not delivery selection switches. Each side of each dispenser may have a Generic
CRIND attached. A GSM (Gilbarco Security Module) may be connected to provide DES
encryption services for the CRINDS on an Interface Unit.
No provision is made to support the Major Oil Company (MOC) CRIND. This differs from
the Generic CRIND, which we support, in the CRIND firmware and in the electrical connections
to the rest of the system. If CRINDs are used, you must use the Gasboy CFN Site Controller II
with software revision 2.0B or greater.
CRINDS must contain the Z-180 CPU board, Gilbarco part number T177-64-G1S, revision
C or higher, with firmware K93744-02.
One or more Gilbarco Universal Distribution Boxes are required. Pumps are controlled from
the interface box using a current loop connection to a distribution box, while CRINDs are
controlled using an RS485/422 connection to a distribution box.
For installations with eight or fewer pumps, a single distribution box may be assembled from
parts that controls both pumps and CRINDs. See the discussion near the end of the Hardware
chapter.
An RS485/422 port connects the interface unit to the Gasboy Site Controller II. The Site
Controller senses an array of pump control units, with one or two pumps on each unit, and an
array of reader terminals. Switches inside the interface unit determine the pump control unit
number and reader terminal number each array begins with.
If there are no cash/credit select buttons or dual price bars on any pumps on an interface box,
you may use any number of price levels, subject to weights and measures constraints. Only levels
0 to 5 will appear at the pump displays.
If there are cash/credit select buttons or dual price bars on any pump, you may use, at most,
price levels 0, 1, and 2, and in addition, level 0 (fallback) must be identical with either level 1
(cash) or level 2 (credit).
The Gilbarco interface unit contains battery backed up memory to store transaction
information in the event of a power failure. Lamps visible through a window on the front of the
unit indicate battery, power, and program status. Lamps in the Gilbarco distribution box indicate
current loop port and RS485/422 port status. If more extensive indications of status are needed,
an RS-232 port on the back of the interface unit allows connection of a terminal to run
diagnostics. A switch and a fuse are located on the back of the cabinet.
