Sam4s SPS-500 Series Program Reference Manual page 175

Keyboard Level
Each keyboard level is a separately defined set of keyboard functions for each key on the keyboard.
For example, separate levels might be required for different lunch/dinner menus. Or, within a
restaurant different keyboards might be set up for pre-check, bar and/or cashier stations. Each
register might contain the functions for each station on a separate level, so that any register could
function at any station by simply changing keyboard levels and key legend sheets.
The SPS-500 has five keyboard levels.
Link PLU
If you wish the registration a PLU to automatically cause the registration of another PLU, enter the
number of the PLU you wish to register automatically in the LINK PLU field of the appropriate PLU
Status Group.
Macro
Macros record key sequences for later execution. Up to 40 macros may be recorded and executed by
pressing a function key or by entering the appropriate macro number and pressing a function 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 employee memory,
PLUs, or reporting. Memory allocation allows you to maximize the features you need while minimizing
the features you do not need.
Modifier
Preceding a PLU entry, a modifier key changes a digit of the PLU number, causing a different PLU to
be registered. Modifier keys can be set to change any of the 14 PLU digit positions to any specified
digit (0-9). More than one modifier key can be pressed in succession to alter the PLU code.
No Sale
No sale is an operation to simply open the cash drawer.
NON-PLU Code
The NON-PLU Code program must be set if you wish to scan UPCs (using the EAN 13 code) with
embedded prices, weights or quantities.
Within the EAN 13 code, the first two digits (part a) are used as an identifier and the last digit (part c)
is used as a check digit. The remaining 10 digits (part b) contain the product code and the price (or
weight or quantity).
Override
Override is an operation used to bypass a programmed price or HALO.
