Sam4s ER-920 - Memory Allocation

96 • S-Mode Programming SAM4s ER-900 Series Operator's & Programming Manual v.1.28
Memory Allocation
Memory Capacity
4 mb for models produced before March 2013 (serial number 1302XXXXXX or earlier.)
Memory on these models is fixed and cannot be expanded.
16 mb for models produced after March 2013 (serial number 1303XXXXXX or later.) No
further memory expansion is available.
Minimum and Maximum Feature Capacities
The memory allocation program determines how memory is divided to support each feature.
(Maximum limits for 4mb memory models are noted in parenthesis.)
1. PLUs - you must allocate a minimum of 300 PLUs, a maximum of
approximately 23,950 (4000) is determined by available memory.
2. Clerks – you must allocate at least 1 clerk, with a maximum of 99. (Note you
also must allocate at least one guest check for each clerk.)
3. Groups – you must allocate at least 1 group, with a maximum of 99.
4. Guest Checks – you can allocate a maximum of approximately 500 (200) hard or
soft checks
5. Soft Check Lines – you can allocate a maximum of 230 (100) lines per check
6. Check Type – select hard or soft checks
7. Levels – allocate one or two price levels.
8. Mix & Match Discount Tables – default is 10 you can allocate a maximum of
100.
9. Electronic Journal – Default is 1000 lines; maximum is 50,000 (1000) lines.
Important Memory Allocation Notes
1. Memory variable maximums are theoretical. For example, if all other variables are at or
near zero, then 23,950 (4000) PLUs are possible. Note check memory, especially soft
check memory, and clerk memory consume considerable memory.
2. Using the clerk interrupt feature requires allocation of at least one guest check for each
clerk and sufficient soft check lines to support the interrupted transaction (i.e. if 20 soft
check lines are allocated, a transaction with up to 20 lines can be interrupted.) See
system option flag # 26 to select clerk interrupt operations instead of table management
(check tracking) operations.
3. All models default to 1000 lines of electronic journal. For models with journal printers,
you may wish to set electronic journal to “0” so that memory may be used for other
options.
