Master
This is the controlling unit in an IRC system. The master will have
generally the most memory of the units in the system. It is used for
real-time transmission, to consolidate totals from one or more
registers, to download programming, sending information to a remote
printer, and consolidation of sales data for further processing. For
example, a back office application.
Master Reset
This operation will reset all the totals in the machine. There are three
(3) types of master resets.
MRS-1 (Master Reset-1): Clears the entire available memory
and restores the initial factory default values for the keyboard
and PGM-mode programming.
MRS-2 (Master Reset-2): Clears the entire available memory,
allows free assignment of the ten-key pad, eliminates the
Direct Department and PLU assignments, and restores the
initial factory default values for all other PGM-Mode
programming.
MRS-3 (Master Reset-3): Clears the entire available memory,
allows the input of the product serial number and the
assignment of the ten-keypad, eliminates the Direct
Department and PLU assignments, and restores the initial
factory default values for all other PGM-Mode programming.
Mode Switch (Mode Lock)
This is the control lock of the register. Determines the “Mode” of
operation of the register.
Option
A device or function that can be added to a register. It is usually not
found on the unit out of the box.
Patch
A “Patch” is a service function that allows the program in a ROM to be
modified without replacing the chip. It is properly called a SSP. The
first step in a patch is the number of the patch. Leading zeros are
input as part of the patch step. Usually, when several patches are out
for a unit, then a new version ROM will be made available. This new
ROM will incorporate the previous patches issued.
PBLU
Previous Balance Look Up: This is a guest check system. The guest
check will show the current balance of items ordered, until the check is
“serviced”. It may or may not include tax and a gratuity.
PLU
Price Look Up: a PLU is a section of memory where an item is
assigned a number, a name, and a preset price. The machine will
locate this item by number and add the amount to the sale. The price
does not have to be input through the keyboard during a sale.
PLU Groups
This is a section of memory where the PLUs are grouped and stored
for reporting purposed. This total is updated on the fly. To see the
amount of sales, an “X” (Read) or a “Z” (Zero out) report has to be
taken.
PLU (Linked)
A Link PLU is used when more than one and up to five items is
registered with one key depression. Each unit price is accumulative
for those PLU items associated to the link type operation and are
printed with the individual unit prices. For example, Bottle Deposits,
specials or messages.
