Macro
Macro keys may be programmed to record, and then later perform, up to 50 keystrokes.
For example, a macro key could be set to tender (preset tender) a common currency, such
as $5 into the cash key.
Memory Allocation
Memory allocation is a program that determines how the system memory is divided to
provide the correct features for your application. For example, you may require more or
less clerk memory, PLUs, or electronic journal memory. Memory allocation allows you to
maximize the features you need while minimizing the features you do not need.
Mix & Match
Retailers often offer discounts when multiples of different items are purchased. For
example, the offer: “save $5 on any three bottles of wine” can be handled by a mix and
match discount. The default NR-500 Series can accommodate up to 10 different mix and
match discounts, the total can be increased to a maximum of 100 through memory
allocation.
Multiple Receipts
In some cases, for example where a mail-in rebate is offered, an extra copy of a receipt is
needed. If allowed, the receipt must be re-printed immediately, before another transaction
is started.
Negative PLUs
As you program PLUs, you will find a setting to make them negative (normally they are
positive). Positive PLUs are used for items that add to the sale. Negative PLUs are used
for items that subtract from a sale, like individual store coupons or bottle deposit credits.
NLU
Number Look-Up (NLU) refers to PLU code that is accessed when a Keyboard PLU is
used. In the default program each Keyboard PLU will look up the appropriate numeric
PLU, beginning with PLU #1 for Keyboard PLU key #1 and continuing sequentially
through the keyboard.
However, this numbering sequence may be impractical for some applications. For
example, Keyboard PLU #1 may represent a can of Diet Pepsi. The merchant may wish
to have the Keyboard PLU look up the UPC code number for Diet Pepsi, which is
“120500”. Using this program you can change the Number Look-Up (NLU) for the
keyboard PLU to any 14-digit number you choose.
No Sale
No sale is an operation to simply open the cash drawer. No sales are counted and reported
on the financial report.
Not Found PLU
For small merchants, the NR-500 Series can build a PLU file “on the fly”. Each time an
item is scanned (or entered by PLU number) that is not in the PLU file, the operator is
prompted to enter the price and other options for the item. At the end of the day, the “Not
