SECTION 1 – INTRODUCTION & INSTALLATION
INTRODUCTION
CellScale™ establishes Measurement Systems International (MSI) as the first company to produce a weigh-
ing system that fully integrates omnidirectional, wireless communication. The innovative new concept, called
“cellular weighing,” offers several ways to dramatically improve your process of weighing and information
acquisition. CellScale™, the system’s central weighing and communication controller, gives you an unprec-
edented foundation for building your weighing system. For the first time, your system may expand to virtually
any combination of load sensors, weight displays and other data recorders — without requiring cables.
Free of the hindrances of cables, your system will be more versatile. Your load sensors and displays may move
freely during operation, and your stationary components can be located anywhere you choose. CellScale™ also
eliminates the significant cost of cable and conduit installation.
CellScale™ controls all the functions that turn a “dumb” load sensor into an advanced weighing system: zero,
tare, check weighing, totalizing, set points, statistics and many others. The functions can be applied simultane-
ously to numerous load sensors.
CellScale™ consolidates the functionality of dozens of weighing components into one unit. It will save you
money by eliminating redundant displays, radio systems and other components.
The Model 9000 CellScale is Legal for Trade (COC# 05-077) when used in conjunction with approved Load
Cells and Scale bases. The NTEP Certificate covers the Model 9000 CellScale, 9750A Indicator, the 3750CS
indicator, and the 9020 CellModem. LFT status of the 6260CS and other MSI Crane scales is pending.
INSTALLATION
The CellScale™ features a heavy duty, milled enclosure rated at NEMA 4 IP 65 or NEMA 6 IP 67 with the
long range antenna option. Whether you utilize crane scales, lift truck scales, hoppers or any other scale,
CellScale™ installs easily. It bolts vertically or horizontally either to your load sensors or near your load sen-
sors. The CellScale™ is usable immediately because it does not require an FCC license.
If there are no peripheral devices such as a printer or scoreboard, setup consists of installing the unit in its per-
manent location (see installation templates), plugging in the Antenna and load sensors, and applying power.
Power–MSI9000
The CellScale is powered by any DC source from 9V to 30V or optionally with 85-265VAC. The universal AC
option can also be used with high voltage DC (120VDC to 300VDC)
FIRMWARE VERSION NOTICE
This User Guide is intended for CellScale equipment that uses MSI’s next generation of RF Modems. This
guide applies only to Models 9000 and CellScale embedded Crane Scales manufactured after 5/1/06. There are
menu differences and feature additions not found in first generation CellScales. These devices all have code
installed starting with version 5-xx. Version 5-xx is not compatible with older CellScale manufactured before
4/1/06 and the Modems installed cannot communicate with CellScale equipment not specified as having 2nd
generation modems.
Older CellScale equipment can be upgraded to 2nd Generation by exchanging the Modems and updating the
software. Contact MSI for pricing information.
Previous Versions of this User Guide are available by special request.

CELLSCALE CONNECTORS
Power and Remote Switches Cable
Power is supplied through a pre assembled cable (MSI P/N 12020). It provides for DC power in (9-30Vdc),
two switches, and a remote LED indicator. The switches and LED are supplied by the end user.
Blue – Connect to Battery Negative or supply ground. It is generally best to connect this directly to the battery
negative terminal, or where the negative terminal is attached to the chassis.
Brown – Connect to Battery Positive (9-30VDC). Again, a direct battery connection is usually best to avoid
interference with vehicle electrical systems. The CellScale is internally fused. If connected to a breaker or fuse
panel, use 2A at 12V, 1A at 24V. Fast blow or medium blow fuses are acceptable.
Black – Switch 1 input. Connect to a Normally Open push-button switch. The other switch terminal must
connect to the Blue wire (ground). If this feature is not used, insulate the end of the wire to prevent it from
shorting.
White – Switch 2 input. Connect to a Normally Open push-button switch. The other switch terminal must
connect to the Blue wire (ground). If this feature is not used, insulate the end of the wire to prevent it from
shorting.
Gray – Remote power indication. Connect to the anode of a remote LED. The LED cathode must connect
to the Blue wire (ground). No current limit resistor is required, current drive is provided by the CellScale
(~20mA). If this feature is not used, insulate the end of the wire to prevent it from shorting. Suitable for LEDs
with VF 1.6V to 2.4V@ 20mA. Not suitable for Blue or White LEDs due to their VF >3V.

Sensor Input
The sensor input connector has twelve pins. A minimum scale connection consists of +Excitation, -Excitation,
+Signal Ch1, and -Signal Ch1 (4 wire). The user can add +Sense and -Sense for a 6 wire connection to a sum-
ming box or 6 wire connected load cell. Plus and minus sense can be left unconnected when not needed. To add
a second sensor input, use +Signal Ch2 and -Signal Ch2. Sensors connected to Channel 1 and Channel 2 share
excitation. The remaining 4 pins are control signals for the 9008 CellScale Multiplexer. The binary code from
these pins corresponds to the sub-channels designated by the scan list.
Figure 1 shows the pinout of the sensor input for the standard 2 Channel CellScale. The view is into the
CellScale, which corresponds to the solder cup view of the mating connector (MSI P/N 11968). Contacts A-H
are sized for up to 20 AWG wire. Contacts H, J, K, and L are sized for up to 16 AWG wire. Twisted pair wire is
recommended with pairs for Signal Ch 1, Sense, Excitation, and Signal Ch 2.

Figure 1 - 2 Channel Sensor Input Connector
The 2nd A/D Option, 4 Channel CellScale adds a second connector opposite to the first. This connector is
wired identically to figure 1 except Channel 1 becomes Channel 3 and Channel 2 becomes Channel 4.
The digital lines, if used, should be pair 1 with Dig Gnd and Dig0, pair 2 with Dig1 and Dig2. Do not use
digital ground for any load cell connection or shield. Shields should be terminated to the shell.
In addition an overall shield should be used with the shield terminated to the shell of the connector. MSI
recommends dual shields with a foil inner shield and a braid shield overall. Outer jackets should be care-
fully chosen for the intended environment. MSI supplied cables are jacketed with polyurethane, which gives
excellent abrasion resistance and is suitable for outdoor use. Do not use common PVC jackets, unless they
are certified for the environment the system will be used in. PVC has poor abrasion resistance and poor water
resistance. There are newer, specialized types of PVC which are far superior for industrial applications. In
short, know your environment, make sure the cable chosen is suitable.
For maximum reliability, use only rosin core solder for wire connections. Clean all flux residue with flux sol-
vent and insulate each solder cup with heat shrink. After wiring and verifying, the connector should be potted,
or an environmental backshell should be employed (not supplied by MSI). MSI recommends 3M DP100 as
a potting compound. However, using DP100 prevents any future repair of the cable. A silicone based potting
compound should be used if this is a concern.
MSI supplies pre wired and potted cables for connections to summing boxes or other junction boxes. These can
be ordered in many lengths and watertightness is assured.
Set Point I/O Connector
The Optional Set Point I/O cable (MSI P/N 12018) provides three Set Point outputs coupled to internal solid
state opto-isolated relays. These relays are capable of 60V at 350mA. The relays share a common. Since the
relays are bidirectional the common line can be connected to ground or any voltage up to 60V peak. This
allows DC voltages of 60V peak or AC sine wave voltages of 48VRMS to be switched. However, if the
common line is used for the positive input or AC voltage is used, the isolated input is not usable.
In addition, the I/O cable provides an isolated input that controls the Switch 2 functions (see System Menu
for details on programming the function of Switch 2). This input will function with any DC source from 5V to
60V. Apply the positive voltage to ISO Switch Hi and the lower voltage to common. For example, supply 24V
All unused wires must be insulated individually (electrical tape or heatshrink) to prevent shorting out
critical control circuitry.

Comm Port Cables
The CellScale comes standard with one Comm port wired for RS-232 (MSI P/N 501705-0001) following the
AT standard for 9 pin serial cables (DCE). An unterminated cable is available (MSI P/N 12023) if you wish to
wire your own serial cable for RS-232 or RS-422 or RS-485. Comm Ports 1 and 2 are wired identically. Note
that Comm Port 2 is not installed in RF Modem equipped CellScale 9000s.

RS-422/485 Operation
RS-422 and RS-485 serial connections are used when long wire runs are necessary. The 485 spec covers cable
runs up to 4000’. 422 and 485 are differential transmissions and require twisted pair wiring to achieve common
and normal mode rejection. Although short runs of 422/485 cabling is often just two wires, a ground reference
is required. Usually the ground reference is connected through resistors to prevent ground differential cur-
rent flow. RS422/485 connections require a termination resistor to reduce reflections. See wiring diagrams for
details.
Both RS-422 and RS-485 are multi-drop capable. The CellScale can drive up to 32 receivers on one twisted
pair. Although the CellScale uses standard RS-485 drivers, the standard software does not have a full duplex
protocol. Contact MSI for custom solutions for networking with RS-485.

4-20mA Output Option
The 4-20mA Output Option (4m Cordset MSI P/N 12879) requires a loop supply input. Provide loop voltage
(typically 24V DC , but will operate from 6.5-100V DC ) to the Loop In pin. The minimum voltage is sense
resistor dependent. The minimum loop voltage is equal to (.02 * (Rsense+Rwireing) + 5V). If isolation is not a
concern, the DC supply for the CellScale (9-30V DC ) can function as the 4-20mA Loop In supply. With the dual
4-20mA option, each output is isolated from chassis ground and each other, assuming separate loop supplies.
For details on setting up the 4-20mA output(s), refer to page 89 in the calibration section.

The CellScale is based on a high performance embedded version of the 80186, the Am186ES which performs
all control of the A/D converters, the I/O and interfacing to the Cellular Modem. The modem has a secondary
microcontroller to handle RF traffic and controlling the hopping patterns.
The A/D converters are 24 bit Sigma-Delta converters with AC excitation capability. Each A/D has two inde-
pendent inputs allowing multiple scale platform capacity.
The CellScale read only memory is Flash based allowing easy upgrades and software maintainability. The
RAM memory is battery backed as is the Real-Time-Clock/Calendar.
An accelerometer based motion and tilt transducer is available as an option. This advanced capability offers a
means to compensate motion and tilt for vehicle and other mobile weighing situations that conventional scales
can’t handle.
The Power Supply is designed for inputs from 9-30VDC. The supply is transient protected for direct vehicle
power, or can run from any 12V SLA battery. Enough power is available to power up to forty 350 load cells.
One user available comm port is available. Comm 1 is software configured as an RS-232 or RS-422/485 port.
A second port is available in 9000s not equipped with the RF Modem.
Three isolated outputs and 1 isolated input are provided for set points and trigger inputs. In addition, 2 pro-
grammable switches inputs are found on the Power connector.

SECTION 2 – RF SCALE COMMUNICATIONS – THE CELLSCALE SYSTEM
INTRODUCTION
The 9000 CellScale is the key component of the MSI CellScale™ System. The CellScale system uses frequency
hopping spread-spectrum RF Modem technology transmitting in the 2.4 GHz ISM band.
RF Modems have been problematic as the RF bands are very hostile, corrupted by noise, path loss and inter-
fering transmission from other radios. Even in a pure interference-free environment, radio performance faces
serious degradation through a phenomenon known as multipath fading, a problem particularly prevalent for
indoor installations. Multipath fading results when two or more reflected rays of the transmitted signal arrive
at the receiving antenna with opposing phase, thereby partially or completely cancelling the desired signal.
Spread spectrum reduces the vulnerability of a radio system to both interference from jammers and multipath
fading by distributing the transmitted signal over a larger region of the frequency band than would otherwise
be necessary to send the information. This allows the signal to be reconstructed even though part of it may be
lost or corrupted in transit.
Spectrum has been set aside at 2.4GHz in most countries for the purpose of allowing compliant spread spec-
trum systems to operate freely without the requirement of a site license. In the USA, there are absolutely no
site licensing requirements. The CellScale system is also programmable for use in most European countries.
Please contact MSI for worldwide compliance information.
NETWORK DESCRIPTION
The CellScale system uses frequency hopping which is produced by transmitting the data signal as usual, but
varying the carrier frequency rapidly according to a pseudo-random pattern over a broad range of channels, in
this case 86 discreet frequencies. These 86 frequencies are combined in different “hopping patterns” to provide
64 separate networks. The CellScale network uses a ‘Star’ network topology. One unit, usually the CellScale,
is designated a ‘Master’. The Master transmits a sync pulse on a regular basis, providing synchronization of
all remotes in the designated Network. Thus it forms the center of a cell. MSI provides three products capable
of being the master unit: the CellScale, the 9300 Crane Scale, or the Trans-Weigh CS Crane Scale. Up to 16
remotes can access the master unit. Current MSI provided remote devices include the 3750CS Indicator, the
9750A Handheld Indicator, the 9850 Indicator, and the 9020 CellModem. Multiple remotes can coexist on one
network, or can be easily switched to other networks as required.
The CellScale system uses TDMA (Time Division Multiple Access) to arbitrate between multiple remotes.
Each remote is assigned a specific time slot thus guaranteeing data throughput.
NETWORK EXPANSION
You can expand your system with virtually unlimited combinations of additional CellScales™, CellModems,
and CellScale Indicators (3750CS, 9750, and 9850).
You can also expand your system with any component that features an RS-232/422/485 input/output (I/O) port:
desktop/laptop computers, printers, scoreboards, relay boards and many others.
There are three ways to connect additional components to your cellular weighing network.
1) Via MSI-3750CS or 9850 Indicators:
RS-232 components can be linked directly to the Indicator Comm Ports with a cable. The 9850 offers two
available Comm ports, one of which is software configurable to RS232/422 or 485. The 3750CS offers 1
RS-232 port.
2) Via CellModem, MSI-9020:
Components can be linked to a remote radio modem, the MSI-9020 CellModem. It enables wireless cel-
lular communication with CellScales™ and the rest of your cellular weighing network. CellModems are
linked via RS-232/422 to peripheral equipment. If necessary, a USB to serial converter can be used for
Computers not equipped with RS-232 serial ports. MSI recommends Keyspan™ products such as the
USA-19HS for this purpose.
3) Via CellScale™:
Each CellScale™ provides an I/O to connect directly to other system components. CellScales™ are linked
via RS-232/422/485 to peripheral equipment. Generate printed and electronic reports automatically for

others.
ANTENNAS
To meet FCC licensing rules, you must use only antennas supplied or recommended by MSI. MSI offers
the CellScale with six antenna choices: 1) Standard Antenna – This is a small 1/2 wave antenna that mounts
directly on the 9000 CellScale enclosure and is suitable for most short to medium range applications. 2) Long
Range Antenna – A high gain antenna that is remotely mounted from the 9000 with a low loss coaxial cable.
This omnidirectional antenna increases the range up to 4 times. The 10' cable allows placement of the antenna
above the 9000 for ease of clearing possible obstacles to data transmission. 3) Vehicle Mount Whip Antenna
– This antenna mounts directly to the roof of mobile vehicles and is weatherproof. 4) For maximum range,
a 14dBi Gain Yagi Antenna is available by special order. Please contact MSI for details. 5) Corner Reflector
– Often the best choice for a wall mounted antenna. MSI offers a 14dBi and a 9dBi Corner Reflector. 6) Patch
Antenna – For applications where the standard antenna is vulnerable to physical use or outdoor applications.
The Patch antenna is mildly directional which requires more care in antenna placement for long range applica-
tions. Patch Antennas are available by special order only.
Antenna placement is critical to problem free use of your CellScale system.
1) Be sure a relatively clear transmission path exists between the 3750CS and associated CellScale master
devices. The radio signals travel primarily by line of sight (LOS), and obstructions between stations will
degrade the system performance. LOS is less important as distances decrease.
2) When using the long range antenna, mount the antenna on a tower or other elevated structure to ensure
that you have a clear LOS transmission path. This will raise the antenna to a level sufficient to clear sur-
rounding terrain and other obstructions. It is not necessary or desirable to provide a ground plane for the
antenna.
3) Never use a directional antenna (e.g. a Yagi, or a corner reflector) on a mobile system. However, fixed sta-
tion locations can often benefit from directional antennas when the location of the other components of the
RF network are always in the same general direction.
4) If using the meter mounted standard antenna, ensure that the antenna is not blocked by any metal. Trans-
mission is good through most kinds of glass so mounting a meter next to a window should work fine. If
there is no clear line of sight place to mount the 3750CS, consider switching to the long range antenna so
the antenna can be remoted.
5) The standard and long range antennas are vertical plane devices. Do not mount them sideways. They
should always point up. It also works to point them down, when high off the ground (such as on the under-
side of a large bridge crane). The long range 9dBi Antenna is particularly sensitive to off axis mounting.
Use a carpenters level to ensure the antenna is exactly 90° perpendicular to the earth.
6) Do not mount an omnidirectional Antenna next to a metallic or concrete surface. This can result in reflec-
tions and undesired RF characteristics. For this application, use a Corner Reflector.
7) After installation, you must seal the Antenna connection with an Adhesive Heat Shrink Boot. Failure to
seal the Antenna may result in liquid destroying the Antenna, or the CellScale.
MSI does not recommend extending the coaxial cable beyond 3 meters. At 2.4GHz more loss will result from coax losses
than are gained by raising the antenna. If you must extend the antenna, use a very low loss 50Ω coax such as RG-214 low
loss varieties. For very short extensions (<1m), cables made with RG-316 are suitable.

SECTION 3 – TERMINAL ACCESS MODE
One way to setup, control, calibrate, and receive data from a CellScale is using a terminal program through
Comm Port 1. Tested terminal programs that function well with the CellScale include ProComm Plus,
Qmodem, HyperTerm (shipped with many versions of Windows), WinTerm, and ZTerm or Microphone (for
Macintosh). Usually a VT102 emulation is used. All commands are single letter except when entering data.
Settings for your terminal program are: 9600 baud, 8 bit, 1 start bit, 1 stop bit, no parity, Handshaking usually
not required, but you can turn on Xon/Xoff if you desire.
The Terminal access mode is initiated by connecting a terminal to Comm Port 1. The Terminal Access Mode
should start. Refresh the display by pressing [Return] (generates CR/LF). This will bring up the Main
CellScale Menu.
!If you are unable to connect to the 9000, the 9000 might be in its “Host” mode. To force the Terminal
Access Mode, type ;MSI9MSI9 [Return] Start with a semicolon “;”. The “MSI” must be capitals.
Host mode baud rates might have been changed, so match baud rates of the current connection.
DIALOG BOXES
The CellScale will place dialog boxes on the terminal screen in response to several stimuli. Overloads, set
points and other events will cause a dialog box to appear. Push ESC to remove the dialog box. The box will
reappear in 45 seconds if the condition has not changed.
MENU CONVENTIONS
Make a menu selection with designated numbers or letters. A few critical menu selections require that case is
correct, but most commands work with upper or lower case characters.
Data entry for numeric values are terminated with the return key on your terminal. Data entry for channel
names and ID names are terminated with the return key. Data entry for strings are terminated with the ESC
(escape) key.
Menus are entered with numbers or letters and are left with the escape key [ESC]. Each menu is numbered in
the lower left corner of your terminal screen. The Main CellScale Menu is number 0001. All submenus have
numbers. The sequence of numbers shows the ‘path’ the menu was reached by. Some menus have a menu
depth of 3, 4, or 5 levels. Again, the use of the escape key to will allow you to return to any level. The menu
numbers are not illustrated in this manual, but are present in every menu screen.
Use the menu numbers when contacting Customer Support to report problems or ask questions.
Brackets [ ] are used to indicate keys that should be pressed while using the Terminal Access Mode. Text
strings are indicated with quotes “ttttttttttxttttt”. Do not type the quotes. [Return] indicates the return key on
your keyboard (sometimes referred to as enter) and is used to complete the entry of menu items (not strings)
when more than 1 number or letter is required.
MENU SCREEN ILLUSTRATIONS
The main and secondary menus are all illustrated here. For those menus with simple purpose, the operational
procedure will be explained. For some more complex functions, the text will refer you to subsequent chapters
on the proper use of the menu.

1) Backup data after every cal – Choosing ‘Yes’ causes the CellScale to transfer all calibration data in the
Flash memory after every calibration procedure. Choosing ‘No’ will mean the most current calibration is
only saved in battery backed RAM. In this case if you were to update the program, calibration would be
lost. The reason to select ‘No’ is if you wanted to try recalibrating without the risk of losing the previous
calibration. Therefore, if the cal did not work out, the previous cal can be restored by using ‘r’ from this
menu.
