STANDARD FEATURES
Scale Monitoring
Each 9750A can log on to 64 different networks allowing it to
serve up to 64 separate CellScales. Easy 1 button scale changes.
Each CellScale can access 32 independent Scale Channels. Sup-
ports display of up to 8 CellScale channels simultaneously.
Calibration
Via RF, the 9750A can calibrate any CellScale system. The
system is sealed at the CellScale.
Keypad
24 keys – 6 user programmable (12 functions), 11 key alphanu-
meric, and 7 scale control keys
Push button Functions
Fixed keys:
Power: On/Off
Zero: Remove residual weight on scale
Net/Gross: Switch between Tared weight (Net) and Gross weight
Tare: Tare out empty container weight and switch to Net mode.
Alpha: Allows alpha character entry, upper and lower case
Enter: Store parameters or enter menus
Setup: Setup scale functions
0-9 with Alpha characters
PROGRAMMABLE FEATURES
• Automatic or Manual Tare entry
• 32 Set points with messaging capability

• Each ID code has an 8 character name, two 20 character
print strings, and stores independently units, tare, total with
weighments counter, and full statistics.
• Selectable Automatic Power-Down, for battery power savings.
• Backlight On, Off or Automatic
• Lock –The user can lock any or all features to prevent tampering
with setups. Protected by password.
• RS-232 I/O will output on demand, on a change, regular time
interval, on a set point, on Total, by computer control or continu-
ously.
• RS-232 I/O provides full output formatting to interface with
computers, printers, scoreboards and most serial devices.
• Send / Print: Output user confi gured print strings to Comm Ports
or via RF to any connected host.
• Manual or Automatic Data Logging. Up to 128 kbytes of storage
(adequate for up to 6400 weight recordings)
Display
• 64 x 128 Full Graphics Module
• Multiple Font sizes, up to 8 lines of 21 characters
• Annunciators for measurement modes
• LED backlighting with timer for battery savings
Calibration Parameters
See CellScale specifi cations. All calibration data is stored in
the CellScale, allowing any 9750A to use any CellScale based
system without recalibration.
Real Time Clock
Supports date / time stamping in US or European formats.
Backed up by a replaceable Lithium Battery (Typical life >5
years).
Data I/O
1 Comm Port, RS-232. Baud Rates: 300, 600, 1200, 2400, 4800,
9600, 14.4k, 19.2k, 28.8k, 38.4k, 57.6k, 76.8k, 115.2k, and
230.4k. Software and hardware handshaking.
ID
Up to 32 IDs can be stored in any connected CellScales and are
identifi ed by Alpha-numeric ID names. Each ID stores Totals,
Statistics, Tare values, and two 20 byte string messages.
Totalizing & Statistics
Stored in connected CellScales, displayed on the 9750A. Total
weight up to 999,999,999. Weighments counter up to 65,535.
Totals and statistics are stored with each ID register. Each ID
code keeps full statistics on totaled weighments. Included are
Standard Deviation, Average, Minimum, Maximum, and Coef-
fi cient of Variance.
Data Logging
Two independent 64kByte battery backed memories for manual
or automatic storage of weight data. Automatic storage based on
time interval, set points, or loading conditions.
Audible Set Points or Totalize Indicator
Coupled with the internal Set Points, an alarm can sound at any
weight. Can also be used for accept or an out-of-limits indicator
for blind check-weighing. Can also be confi gured as a totalize
alert.
Text Messaging
Able to receive and transmit user entered messages for display
on the LCD. The 9750A replies with auto and manual replies
to received messages. Audible alerts possible by including the
ASCII “BEL” character.
Bar Code Interface
The 9750A can directly read industry standard Bar Code scan-
ners and append the bar code data to weight, date, and time data
generated by the CellScale. Pass thru data can be sent directly to
host computers via MSI RF modems.
ACCESSORIES
AC Adapter / Battery Charger
90-260 Vac or 130-350 Vdc Option.
Vehicle Charge Adapter
Cigarette type charge adapter. 12-24VDC, fused at 5A
Bar Code Scanner
Several scanner types available. Contact MSI for specifi c appli-
cation information.
