9750A HANDHELD RF REMOTE INDICATOR for CELLSCALE

SECTION 1 – INTRODUCTION & ORIENTATION

INTRODUCTION

The Measurement Systems International MSI-9750A RF Remote Indicator is an accessory component of MSI's

CellScale® System. Combined with 1 or more CellScales, the 9750A provides complete control over all scale and

data functions. The 9750A serves as a remote terminal for any CellScale and has no internal measurement capa-

bility. One 9750A can read the output of many CellScales, and 1 CellScale can also provide data to many 9750's.

The backlit, alphanumeric graphic display provides precise, unambiguous indication of operating modes such as

Net, Gross, or Total. The 9750A can calibrate a CellScale remotely and provides a user interface to the advanced

features of the CellScale. The CellScale system is digitally calibrated from either the 3750CS Indicator, a 9750A

Indicator, or with a terminal program hooked directly to the CellScale model 9000. The 9750A combined with a

CellScale is designed to meet or exceed the requirements of all regulatory agencies.

Firmware Version 2-XX

KEY DESCRIPTIONS

The POWER key turns the 9750A On and Off. The POWER key must be held for 1 second to ensure startup.

The ZERO key is used to zero out residual weight on the scale. When entering numbers or strings the ZERO key is used

to Clear (delete) characters.

The TARE key is used to zero out the weight of containers, trucks, or carriers and to place the scale in the Net weight

mode.

The NET/GROSS key allows the operator to alternate the weight display from Net (Tared) weight to Gross weight. In

some Legal-for-trade jurisdictions, the Gross weight display is limited to 3 seconds.

The SETUP key allows entry into the setup submenus. Use this to ﬁnd menus for setting the Date and Time, setting up

the function keys, controlling the display mode and backlight, password locks, calibration, etc.. The key is also used for

ESCape. Use ESC to return to the previous menu, or display mode.

The ENTER key ﬁnalizes the entry of numeric or alphanumeric text entries. It also provides an alternate way to maneu-

ver through menus combined with the cursor keys. Pressing ENTER before certain keys takes you directly into various

modes. Pressing ENTER before a Function key enacts the alternate Function key mode.

The ALPHA key is used during text entries to select upper case, lower case or numbers. Sometimes used for negative.

The numeric keypad provides all numerals and letters for data entry. Submenus provide punctuation and control charac-

ters.

The DISPLAY key is used to alternate between single channel displays and multiple channel displays. While in the

multiple channel display, highlight the desired channel using the numeric keys, then press DISPLAY to bring up the

large display. This selected channel is the “Active” channel to which all subsequent actions will be applied. Provides

the decimal point or period in numeric and text entries. Functions as EXIT in menus returning directly to weight display

without having to back through all previous menus.

F1 defaults to TOTAL. Pressing this key will cause the current weighment to be added to the total register. In Auto-Total

modes, the TOTAL key turns Auto-total off and on. Up Cursor in menus.

F2 defaults to CHANNEL. When the CellScale has more than 1 channel deﬁned in its Scan List, the CHANNEL key

will select the next active channel in the list. Precede the CHANNEL key with a numeric entry (1-32) to switch directly

to a channel scan list position. Press SETUP CHANNEL for a shortcut to the “Channel Setup Menu”. Left Cursor in

menus.

F3 defaults to SEND/PRINT. The action of this key is dictated by the Function key menu, but is usually used to send

data to the CellScale or one of its hosts. Used for Insert in text and number entry screens.

F4 defaults to ADDRESS. The ADDRESS key is used to log on to other CellScale Networks. Pressing the ADDRESS

key alone will change the active network to the next deﬁned Network. Preceding the ADDRESS key with a Network

number (0-31) will cause the 9750A to log directly on the entered Network, if it exists and is active.

F5 defaults to VIEW ∑ (total). This key will show the total weight for the current active ID Code. Down Cursor in

Menus.

F6 defaults to ID. Pressing ID will change you to the next deﬁned ID. Right Cursor in menus.

9750A DISPLAY SYMBOLS

The 9750A uses a full dot matrix graphics display which allows 3 sizes of fonts and full use of graphic symbols.

On standard single channel and multi-channel displays, certain symbols are used for scale speciﬁc indications.

The motion symbol indicates that the weight has not settled within the motion window (usually ±1d). While this

symbol is illuminated, the scale will not zero, tare, or totalize.

Center-of-Zero – Indicates the weight is within 1/4d of zero. In the small font it appears as “>0<”.

The Sigma symbol is used to indicate a total weight

GRS – Abbreviation for Gross Weight

Low Battery Symbol – Appears when approximately 10% of battery life remains. The 9750A places the indicator

in various locations depending on the display mode

ton– Indicates US short tons equal to 2000 lb.

tne – Indicates metric tons equal to 1000 kg.

daN – Indicates the force measurement unit dekaNewtons.

Dashes indicate data not yet received from the CellScale, or the RF network is disconnected.

GENERAL INFORMATION

The 9750A is a versatile indicator capable of displaying many data items. As a member of the CellScale family

the 9750A does not stand alone. It is a slave device to a MSI-9000 CellScale. All data displayed on the 9750A is

received via RF from a master CellScale. Many menus in the 9750A depend on information from the CellScale.

Therefore, turn the CellScale on before using the 9750A.

Due to the high data rates in the CellScale system menus usually respond instantly. However there are times

when the CellScale is busy and it will not “service” the 9750A instantly in all circumstances. At these times you

may see the word “Pending” or dashes, or data placeholders which will indicate the CellScale has not yet sent

the required information. Weight displays have priority and are sent before all text strings are updated (such as

channel name, ID name, etc.).

The majority of CellScale installations have only a single scale input. In this case the Multiple Display modes

are not needed. However, even with only a single scale input, Math Channels are available which can be applied

for specialized applications.

MANUAL & 9750A CONVENTIONS

1) Keys used in operations are printed in GRAY and capitalized.

2) Setup procedures are usually shown with the shortcut method of reaching the menu. All menus can also be

reached through the “Setup Select Menu”. Use the [7] key to see all available menu choices.

3) Screen shots are shown for example. Many screens provide additional information to orient the user to the

scale channel, or ID, or selections made. For example, the Function Key Setup menu will show you the current

selection for each key. When you change the function, the previous menu changes to reﬂect your choice.

4) If a function key does not work, it is probably because the CellScale is not setup to support the key. For

example, if only one channel is deﬁned in the CellScale, pressing the CHANNEL key will have no effect.

This also applies to the ADDRESS key. If only one Network has been deﬁned, the ADDRESS key has no

other Network to log onto.

5) Menu Titles are shown at the top of the LCD screen and are fully capitalized.

6) When space permits, selected parameters are shown at the right side fully capitalized.

7) Submenus with multiple choices use a highlighted arrow “4” to indicate current choice(s).

8) When in menus, the ESC key (same as SETUP) drops back one menu level.

9) When in Setup Menus, the DISPLAY key returns you directly to the Weight Display (Exit mode).

10) Cursor Keys (alternate functions of F1, F2, F5 and F6) only function in menus. Use the DOWN (v) cursor

key to enable the cursors then use the UP (^) or DOWN (v) cursor to select line items. Use, ENTER, LEFT

(<), or RIGHT (>) cursor keys to rotate through menu choices or select the associated submenu.

11) If a submenu is associated with a menu choice, either highlight the menu choice with the cursor keys and

press ENTER, or press the numbered key corresponding to the desired menu item.

12) If a menu applies to any channel, pressing the CHANNEL key will select the next channel in the CellScale’s

scan list.

13) If a menu applies to any ID, pressing the ID key will select the next ID in the CellScale’s ID list.

14) To input, for example, an ‘E’, ﬁrst use the ALPHA key to change to alpha mode, then press [2] twice. If you

need two ‘E’s, pause brieﬂy until the display cursor has moved to the next position, then press [2] twice.

15) In single display modes, pressing the ENTER key highlights the whole display to indicate the next press of

a Function key will use the alternate mode (Enter-Function Key).

9750A HANDHELD RF REMOTE INDICATOR for CELLSCALE

UNIT SETUP

The 9750A is simple to setup and use. If there are no peripheral devices such as a printer or bar code scanner,

setup consists of charging the battery, and setting the modem controls to talk to a 9000 CellScale.

BATTERY

The 9750A uses a high capacity Nickel Metal Hydride Rechargeable battery pack. The battery pack will power

the 9750A for up to 8 hours depending mainly on how much the LCD backlight is on. This is a custom battery

pack with over-temp and over-current protection designed for fast charging that must be replaced with MSI P/N

12431. The battery pack should last over 500 charge cycles. NiMH batteries do not suffer from memory effects

and can be charged at any time in the discharge cycle. NiMH batteries do have a fairly high self-discharge rate,

so if the unit is unplugged and idle for a long period of time, the batteries will require charging.

The 9750A LCD will display a low battery warning when there is about a half hour to an hour (depends on back-

light and battery age) of operating time remaining.

REPLACING THE BATTERY

The 9750A is shipped with the battery pre installed. When the battery needs replacing, remove the 6 screws on

the back panel to gain access to the NiMH battery. Gently pull out the battery cable from the interior of the case.

There is a single latch on the connector that must be pushed to separate the battery cable from the 9750A. After

plugging the new battery in, stuff the connector back into the case interior, then reseal the battery cover.

CHARGER ADAPTER

The 9750A battery charger is integral to the 9750A. Input power can any source of 12-24VDC with a minimum

of 20 watts of power. MSI provides two charger sources: 1) Universal AC power: Operates from 86 to 265 VAC

45 to 440 Hz. 2) Vehicle Power: Works with vehicles with 12-24 VDC battery systems (cigarette lighter adapter).

The maximum drain on the power source is 20 watts, but this amount of drain is brief. The source current tapers

down as the battery charges. For 12V systems the maximum drain is about 1.5 amps. A 5A fuse is sufﬁcient to

protect the vehicle electrical system while still providing enough peak power to charge the battery. The MSI

Cigarette Lighter Adapter (MSI P/N 12674) is internally fused with a 5A fuse.

CHARGING THE BATTERY

Turn off the 9750A. Plug in the Charger Adapter in the charge port. Charging will take up to 2 hours depending

on how much the battery was discharged. The 9750A has a charge status indicator on the front panel. The charger

is in fast charge mode when the light is Red. When the light turns Green, the 9750A is ready for use.

Charge Indicator

Off External Power Not Present

Blinking Red/Grn Charge Pending. Either the battery temperature is too high, or the cell voltage is below what

is safe to fast charge. The battery is trickle charged until these conditions are cleared.

Steady Red Fast Charge in progress.

Green Fast Charge Completed. Charger enters pulse phase charge top off. You can use the system

as soon as the green light is on. However, maximum charge capacity is reached about 30

minutes after the light turns green. The Green light will pulse often while in top off phase,

less often during maintenance phases.

When the battery is new, charge the battery for at least 2 hours initially. Then unplug the

adapter, let it cool for 1/2 hour, and then plug it back in. This will initiate another fast

charge cycle that should only last a short time if the battery is functioning properly.

The internal charger is a multi-stage charger. The external adapter can be left plugged in indeﬁnitely. It will

continually pulse charge the battery preventing self discharge and keeping the battery topped off. If the 9750A is

used sporadically, MSI recommends leaving the adapter plugged in while the system is idle.

Do not operate the 9750A with the adapter plugged in. The charger will not charge the internal battery. To ensure fully charging the

battery, turn the 9750A off, remove the power plug, then plug it back in.
