Introduction 1
About This Manual
This manual is intended for use by service technicians
responsible for installing and servicing 120 digital
weight indicators. This manual applies to indicators
using Version 1.0 of the 120 software.
Configuration and calibration of the indicator can be
accomplished using the indicator front panel keys, the
EDP command set, or Version 3.0 or later of the
Revolution™configuration utility. See Section 3.1 on
page 7 for information about configuration methods.
Some procedures described in this
manual require work inside the indicator
enclosure. These procedures are to be
performed by qualified service personnel
only.
Authorized distributors and their employees
can view or download this manual from the
Rice Lake Weighing Systems distributor
site at www.ricelake.com.
The Operator Card included with this manual
provides basic operating instructions for users of the
120. Please leave the Operator Card with the indicator
when installation and configuration are complete.
1.0 Introduction
The 120 is a single-channel digital weight indicator housed in a durable plastic enclosure. The indicator front
panel consists of a large (.8 in, 20 mm), six-digit, seven-segment LED display and five-button keypad. Features
include:
• Drives up to four 350Ω or eight 700Ωload cells
• Supports 4- and 6-wire load cell connections
• Electronic data processing (EDP) port for full duplex, RS-232 communications at up to 38400 bps
• Printer port for output-only RS-232 and 20 mA current loop communications at up to 9600 bps
The 120 is NTEP-certified for Classes III and III L at 6,000 divisions. See Section 7.8 on page 36 for detailed
specifications.
1.1 Operating Modes
The 120 supports the following modes of operation:
Normal (weighing) mode
Normal mode is the “production” mode of the indicator. The indicator displays gross or net weights as
required, using the LED annunciators described in Section 1.3 on page 2 to indicate scale status and the type
of weight value displayed. Once configuration is complete and a legal seal is affixed to the back of the
indicator, this is the only mode in which the 120 can operate. See Section 1.4.1 on page 3 for more
information about normal mode operations.
Panel mode
Panel mode allows the time, date, consecutive number, and consecutive number start-up value to be set
without entering configuration mode. To enter panel mode, press and hold the GROSS/NET key until the TIME
menu is shown. See Section 1.4.2 on page 4 for more information about panel mode.
Configuration mode
Most of the procedures described in this manual require the indicator to be in configuration mode, including
configuration and calibration.
To enter configuration mode, remove the large fillister head screw from the enclosure backplate. Insert a
screwdriver or a similar tool into the access hole and press the setup switch once. The indicator display
changes to show the word CONFIG.
Test mode
Test mode provides a number of diagnostic functions for the 120 indicator. Like setup mode, test mode is
entered using the setup switch. See Section 7.7 on page 35 for more information about entering and using
test mode.

1.2 Front Panel Keypad
Figure 1-1 shows the 120 keypad and LED annunciators.
The symbols shown under the keys (representing up, down, enter, left, right) describe the key functions assigned
in configuration and panel modes. In these modes, the keys are used to navigate through menus, select digits
within numeric values, and increment/decrement values. See Section 3.1.3 on page 8 for information about using
the front panel keys in configuration mode.
Figure 1-1. 120 Front Panel
1.3 LED Annunciators
The 120 display uses a set of eight LED annunciators to provide additional information about the value being
displayed:
•Gr (gross) and Nt (net) annunciators are lit to show whether the displayed weight is a gross or net weight.
• Center of zero ( ): Gross weight is within ±0.25 graduations of zero. This annunciator lights when the
scale is zeroed.
• Standstill ( ): Scale is at standstill or within the specified motion band. Some operations, including
tare functions and printing, can only be done when the standstill symbol is shown.
•lb, kg, oz, and g annunciators indicate the units associated with the displayed value: lb=pounds,
kg=kilograms, oz=ounces, g=grams.
The displayed units can also be set to short tons (tn), metric tons (t), or NONE (no units information
displayed). The lb and kg LEDs function as primary and secondary units annunciators for some
combinations of primary and secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the
lb annunciator is lit for primary units, kg for secondary units.
Table 1-1 on page 3 shows which annunciators are used for all combinations of configured primary and
secondary units. For example:
• If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb LED is lit for primary
units, kg for secondary units.
• If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb LED is lit for primary
units, kg for secondary units. There is no LED for short tons, so the kg LED is used as the secondary units
annunciator.
• If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary
units (tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs
are used as primary and secondary units annunciators.

The 120 indicator can be configured by using the front panel keys to navigate through a series of configuration
menus or by sending commands or configuration data to the EDP port. Configuration using the menus is
described in Section 3.1.3. Configuration using the EDP port can be accomplished using the EDP command set
described in Section 5.0 or by using the Revolution III configuration utility.
3.1.1 Revolution Configuration
The Revolution III configuration utility provides the
preferred method for configuring the 120 indicator.
Revolution runs on a personal computer to set
configuration parameters for the indicator. When
Revolution configuration is complete, configuration
data is downloaded to the indicator.
Figure 3-1. Sample Revolution Configuration Display
Revolution III supports both uploading and
downloading of indicator configuration data. This
capability allows configuration data to be retrieved
from one indicator, edited, then downloaded to
another.
To use Revolution III, do the following:
1. Install Revolution III (Version 3.1 or later) on an
IBM-compatible personal computer running
Windows®98 or later. Minimum system
requirements include a processor speed of at
least 166MHz, 32MB of memory (64MB
recommended, required for NT4, 2000, XP), and
at least 40MB of available hard disk space for
installation.
2. With both indicator and PC powered off,
connect the PC serial port to the RS-232 pins on
the indicator EDP port.
3. Power up the PC and the indicator. Use the setup
switch to place the indicator in setup mode.
4. Start the Revolution III program.
Figure 3-1 shows an example of one of the Revolution
configuration displays.
Revolution III provides online help for each of its
configuration displays. Parameter descriptions
provided in this manual for front panel configuration
can also be used when configuring the indicator using
Revolution: the interface is different, but the
parameters set are the same.

3.1.2 EDP Command Configuration
The EDP command set can be used to configure the 120 indicator using a personal computer, terminal, or remote
keyboard. Like Revolution, EDP command configuration sends commands to the indicator EDP port; unlike
Revolution, EDP commands can be sent using any external device capable of sending ASCII characters over a
serial connection.
EDP commands duplicate the functions available using the indicator front panel and provide some functions not
otherwise available. EDP commands can be used to simulate pressing front panel keys, to configure the
indicator, or to dump lists of parameter settings. See Section 5.0 on page 23 for more information about using the
EDP command set.
3.1.3 Front Panel Configuration
The 120 indicator can be configured using a series of menus accessed through the indicator front panel when the
indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.
Four front panel keys are used as directional keys to navigate through the menus in setup mode. The UNITS ()
and PRINT ( ) keys scroll left and right (horizontally) on the same menu level; ZERO ( ) and GROSS/NET ()
move up and down (vertically) to different menu levels. The TARE key ( ) serves as an Enter key for selecting
parameter values within the menus. A label under each of these keys identifies the direction provided by the key
when navigating through the setup menus.
To select a parameter, press or to scroll left or right until the desired menu group appears on the display,
then press to move down to the submenu or parameter you want. When moving through the menu parameters,
the default or previously selected value appears first on the display.
To change a parameter value, scroll left or right to view the values for that parameter. When the desired value
appears on the display, press to select the value and move back up one level.
NOTE: You must press to save the selected value. The 120 does not automatically save the last-displayed value.
To edit numerical values, press (rightmost digit will
flash), then use the navigation keys to select the digit
and to increment or decrement the value (see
Figure 3.2). When done, press again to save the
edited value.

3.2 Menu Structures and Parameter Descriptions
The following sections provide graphic representations of the 120 menu structures. In the actual menu structure,
the settings you choose under each parameter are arranged horizontally. To save page space, menu choices are
shown in vertical columns. The factory default setting appears at the top of each column.
Most menu diagrams are accompanied by a table that describes all parameters and parameter values associated
with that menu. Default parameter values are shown in bold type.
