Table Sizes
3 Lockout Table: The lockout table stores the numbers of cards that are locked out (for
negative lockout) or unlocked (for positive lockout). The number of card numbers that can be
stored depends on whether bit-mapped lockout or limited lockout is used-bit-mapping is
appropriate only for private-issue cards, limited lockout can handle both private-issue and
bank cards.
With memory-based bit-mapped lockout, 96 card numbers can be stored per entry. (The first
record is used for other information). To calculate the bytes needed, divide the number of bit-
mapped lockouts by 96, then add 1 to get the total number of records. Always round up, never
down. Each entry takes 12 bytes, so the number of records multiplied by 12 is the number of
bytes required. For example, 15,000 divided by 96, plus 1, is 157.25. The number of records is
158. And 158 times 12 is 1896, the total number of bytes to be allocated to bit-mapped
lockout, used or not.
With limited lockout one card number can be stored per entry.
Each lockout entry takes 12 bytes. The minimum number of entries is 2 for memory-based bit-
mapped lockout, 1 for disk-based bit-mapped lockout.
4 Product Table: The product table contains the product codes and product information for
each product or department. This includes the prices or price codes, inventory information,
totals, and tax information.
Each product or department-fuel or merchandise-takes one entry. Each product entry takes 266
bytes. The minimum number of entries is 1, and the maximum number of entries is 99.
5 Pump Table: The pump table holds the information for each pump and hose. This information
includes the product code, price code, and tank number assigned to each hose with the Site
Controller command LOAD FUEL; the pump fill limit and slow-to-cutoff point assigned to
each pump with the Site Controller command LOAD CUTOFF; and the quantity and dollar
totalizer amounts initially assigned to each hose with the Site Controller command LOAD
PUMP and updated after each transaction.
The number of entries in the pump table is determined by the number of hoses configured by
the PUMP configuration program. Each hose takes one entry.
Each entry takes 78 bytes. The minimum number of entries is 33, and the maximum number of
entries is 160.
6 Reader Table: The reader table contains the information for each card reader device,
including both island card readers and stand-alone receipt printers.
The number on the left-reflecting the possible number of entries-should be equal to the
maximum number of readers and stand-alone receipt printers that might be installed at the site.
The number on the right-the number of entries actually used-is equal to the number of readers
and stand-alone receipt printers currently installed at the site. For example, if the site has one
receipt printer connected to the console and two island card readers, then the number of
readers in use is three.
Each possible reader entry takes 56 bytes. The maximum number of possible and used entries
is 32 each.
