1000 System. These tables should contain the same or similar values as those on your "A"
System. Make sure your completed product code assignments and authorization code table are
available at system start-up, so they can be loaded into your system at that time.
Product Limitation
The Product Limitation Code is a one-digit field used to restrict the maximum quantity of product
dispensed per transaction. It can be located anywhere on the card. The Series 1000 can contain
up to ten (0-9) limitation codes with quantities up to 99999. When assigning limitation codes,
choose one with the nearest quantity greater than the vehicle's tank size.
Table 3-1, Product Limitation Codes provides templates for you to enter the values used to
make up the limitation tables for your Series 1000 System. These tables should contain the same
or similar values as those on your "A" System. Make sure the completed table is available at start-
up so it can be loaded into your system at that time.
Additional Entries/Check Digit
Additional entries (PIN, odometer, or manual entry) in a System "A" can be mandatory or
regulated by a check digit. Mandatory entries must be specified at the time of order. If entries are
regulated by a check digit, up to three different check digits may appear: PIN, odometer, and
manual entry. A check digit is a digit on the card that indicates whether the user must make
additional entries upon fueling. The check digits may be in any position on the card and each may
contain a value of either 0 or 1, with 0=not required, and 1=required.
PIN
PIN is not required on a Series 1000 matching an "A" System; however, if it is used, it can be
mandatory (specified at order time) or regulated by a check digit on the optical card. If the PIN is
mandatory, all card users must enter a PIN to fuel; no check digit is required. PIN regulated by a
check digit may be requested on an individual basis by setting the check digit value on the card to
1=required. If PIN is used, you must have specified at the time of order either the "A" system or
CFN Series PIN calculation algorithm and the name of the field on which the PIN is to be
calculated.
