2820i Installation Manual
1.0 Introduction
The 820i is a programmable, multi-channel digital
weight indicator/controller. The configuration can be
performed using the front panel, with an attached
PS/2®1-type keyboard, or using the Revolution utility.
Custom event-driven programs can be written with the
iRite-IDE®language. These programs are compiled
with an iRite-IDE compiler utility, which can only be
downloaded into the indicator. The RLWS Web Update
utility can be used to download 820i firmware upgrades
to a PC from the RLWS web site; Revolution provides
functions for installing the new software into the 820i.
Onboard Features
Features of the basic 820i include:
• Support for two A/D or serial scale inputs, or
total of all scales.
• Eight digital I/O channels on main board, each
configurable as either input or output.
• Two serial ports on main board support duplex
RS-232 up to 115200 bps. Port 2 supports
RS-232 with hardware handshaking; Port 4
supports RS-232, 20mA output, and 2-wire
RS-485 communications.
• Available in 115 VAC and 230 VAC North
American and European versions.
• Configurable print formats can be defined for
up to 1000 characters each. These formats are
used to print gross or net weights, truck in/out
weights, setpoint weights, accumulator
weights, alert messages, and header
information. Additional print formats can be
created using twenty auxiliary print formats.
• Six truck modes to store and recall weights for
gross, tare, and net printing. The truck register
contains fields for ID number, weight, and the
transaction time and date. Weights can be
stored permanently or erased at the end of the
transaction.
• The setpoint engine supports 31 configurable
setpoint kinds. Setpoints can be arranged in a
sequential batch routine of up to 100 steps. If
setpoints are configured as free running
setpoints, they can be tied to program control.
This allows for simultaneous batching
operations to be written with the iRite-IDE
language.
The 820i is NTEP-certified for Classes III and III L at
10,000 divisions. See Section 10.13 on page 103 for
more information about additional certifications and
approvals.
Option Cards
The CPU board provides one slot for installing other
option cards. Available option cards include:
• Analog output card (dual or single) for 0–10 VDC
or 0–20 mA tracking of gross or net weight values.
• Dual-channel serial expansion card provides one
additional RS-485 port or two ports for either
RS-232 or 20mA communications at up to 19200
bps.
• 24-channel digital I/O expansion card.
• 1MB memory expansion card for expanded
database capability.
• Pulse input card for use with pulse count and pulse
rate setpoints.
• Dual-channel analog input card supports 0–10
VDC, 0–20 mA, ambient temperature, and four

Enclosures
The 820i is available in universal (tilt-stand) and panel
mount enclosures. Stainless steel enclosures are rated
for NEMA Type 4X/IP66. This manual provides
assembly drawings and replacement parts lists for the
universal model; supplemental documentation provides
information specific to the panel mount model
(Section 1.4 on page 4).
1.1 Operating Modes
The 820i has two modes of operation:
Normal mode
Normal mode is the weighing mode of the indicator.
The indicator displays gross, net, or tare weights as
required, using the secondary display to indicate scale
status and the type of weight value displayed. Once
configuration is complete and a legal seal is affixed to
the large fillister-head screw on the indicator enclosure,
this is the only mode in which the 820i can operate.
Setup mode
Most of the procedures described in this manual
require the indicator to be in setup mode, including
configuration and calibration.
To enter setup mode, remove the large fillister head
screw from the enclosure. Insert a screwdriver or a
similar tool into the access hole and press the setup
switch once. The indicator display changes to show
scale configuration menus.
1.2 Indicator Operations
Basic 820i operations are summarized below:
Toggle Gross/Net Mode
Press the GROSS/NET key to switch the display mode
from gross to net, or from net to gross. If a tare value
has been entered or acquired, the net value is the gross
weight minus the tare. If no tare has been entered or
acquired, the display remains in gross mode.
Gross mode is indicated by the word Gross (or Brutto in
OIML mode); net mode is indicated by the word Net.
To display audit trail information, press and hold the
Gross/Net mode key for three seconds. Weighing
functions continue while audit trail information is
displayed. Press the Gross/Net or CLR key to exit the
audit trail display.
Toggle Units
Press the UNITS key to switch between primary,
secondary, and tertiary units.
Zero Scale
1. In gross mode, remove all weight from the scale
and wait for the standstill annunciator ( ).
2. Press the ZERO key. The center of zero ( )
annunciator lights to indicate the scale is zeroed.
Acquire Tare
1. Place container on scale and wait for the
standstill annunciator ( ).
2. Press the TARE key to acquire the tare weight of
the container.
3. Display shifts to net weight and shows the word
Net on the display.
Remove Stored Tare Value
1. Remove all weight from the scale and wait for the
standstill annunciator ( ).
2. Press the TARE key (or, in OIML mode, the ZERO
key). Display shifts to gross weight and shows
the word Gross.
Print Ticket
1. Wait for the standstill annunciator ( ).
2. Press the PRINT key to send data to the serial port.
Accumulator Functions
The accumulator must be enabled before use in either
normal mode or setpoint operations. Once enabled,
weight (net weight if a tare is in the system) is
accumulated whenever a print operation is performed
using the PRINT key, digital input, or serial command.
The scale must return to zero (net zero if a tare is in the
system) before the next accumulation.
The Display Accum softkey can be configured to display
the current accumulator value. Printing while the
accumulator is displayed, or when the setpoint
PSHACCUM function is active, uses the ACCFMT
print format (see Section 6.0 on page 54).
Press the CLEAR key twice to clear the accumulator.

6820i Installation Manual
2.0 Installation
This section describes procedures for connecting load
cell, digital I/O, and serial communications cables to
the 820i indicator. Assembly drawings and replacement
parts lists for the universal model are included for the
service technician. See Section 10.11 on page 101 for
dimension drawings.
CAUTION
• Use a wrist strap to ground yourself and protect
components from electrostatic discharge (ESD)
when working inside the indicator enclosure.
• This unit uses double pole/neutral fusing which
could create an electric shock hazard. Procedures
requiring work inside the indicator must be
performed by qualified service personnel only.
• The supply cord serves as the power disconnect for
the 820i. The power outlet supplying the indicator
must be installed near the unit and be easily
accessible.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the 820i
to ensure all components are included and undamaged.
The shipping carton should contain the indicator, this
manual, and a parts kit. If any parts were damaged in
shipment, notify Rice Lake Weighing Systems and the
shipper immediately.
See Section 2.9 on page 11 for parts kit contents.
2.2 Enclosure Disassembly
The indicator enclosure must be opened to install
option cards and to connect cables for installed option
cards.
WARNING
The 820i has no on/off switch. Before
openingtheunit,ensurethepowercordis
disconnected from the power outlet.
Ensure power to the indicator is disconnected, then
place the indicator face-down on an anti static work
mat. Remove the screws that hold the backplate to the
enclosure body, then lift the backplate away from the
enclosure and set it aside.
2.3 Cable Connections
The universal model of the 820i provides six cord grips
for cabling into the indicator: one for the power cord,
five to accommodate other cabling. Install plugs in all
unused cord grips to prevent moisture from entering
the enclosure.
2.3.1 Cable Grounding
Except for the power cord, all cables routed through the
cord grips should be grounded against the indicator
enclosure. Do the following to ground shielded cables:
• Use the lockwashers, clamps, and kep nuts
provided in the parts kit to install grounding
clamps on the enclosure studs adjacent to cord
grips. Install grounding clamps only for cord grips
that will be used; do not tighten nuts.
• Route cables through cord grips and grounding
clamps to determine cable lengths required to reach
cable connectors. Mark cables to remove insulation
and shield as described below:
• For cables with foil shielding, strip insulation
and foil from the cable half an inch (13 mm) past
the grounding clamp (see Figure 2-1). Fold the
foil shield back on the cable where the cable
passes through the clamp. Ensure silver
(conductive) side of foil is turned outward for
contact with the grounding clamp.
• For cables with braided shielding, strip cable
insulation and braided shield from a point just
past the grounding clamp. Strip another half inch
(15 mm) of insulation only to expose the braid
where the cable passes through the clamp (see
Figure 2-1).

An optional dual-channel serial communications
expansion card, PN 67604, is also available. The serial
expansion card provides two additional serial ports,
assigned as port numbers 7 and 8. One port on the
serial expansion card supports four-wire RS-485
communications. Both ports on the expansion card can
support RS-232 or 20mA connections.

8820i Installation Manual
Port 3 uses connector J1 to support USB, Ethernet, and
fiber-optic interface cards.
Note Installation of option cards in connector J1
requires removal of the J1/J10 port selection
jumper (see Figure 2-3 on page 9 ).
Removing the jumper disables RS-232
communications through connector J10. For the USB
interface card only, connections for simultaneous
RS-232 (configured as Port 3) and USB
communications (Port 2) are provided on the USB
interface card.
See the communications interface card installation
instructions for more information.
2.3.4 Digital I/O
Digital inputs can be set to provide many indicator
functions, including all keypad functions. Digital
inputs are active low (0 VDC), inactive high (5 VDC).
Digital outputs are typically used to control relays that
drive other equipment. Outputs are designed to sink,
rather than source, switching current. Each output is a
normally open collector circuit, capable of sinking 24
mA when active. Digital outputs are wired to switch
relays when the digital output is active (low, 0 VDC)
with reference to a 5 VDC supply.
Table 2-3 shows the pin assignments for connector J5.

Digital inputs and outputs are configured using the
DIG I/O menu. See Section 3.2.7 on page 44 for
configuration information.
An optional 24-channel digital I/O expansion card, PN
67601, is available for applications requiring more
digital I/O channels.
Note Digital I/O points can be configured to
count active pulse inputs by setting them to
PROGIN (DIGIN menu) and using the
iRite-IDE DigInSsBbActivate handler with a timer to
turn the handler on and off. However, the fastest pulse
rate that can be counted using a digital input is 10Hz
(10 pulses per second). More demanding applications
can use the pulse input option card (PN 67603) to count
pulses in the 4–4000Hz range.
2.4 Installing Option Cards
Each option card is shipped with installation
instructions specific to that card. The general procedure
for all option cards is as follows:
CAUTION
Option cards are not hot-pluggable.
Disconnect power to the 820i before
installing option cards.
1. Disconnect power to the indicator. Remove
backplate as described in Section 2.2 on page 6.
2. Carefully align the large option card connector
with connector J6 on the CPU board (see
Figure 2-3 on page 9) or J1. Press down to seat
the option card in the CPU board connector.
3. Use the screws provided in the option kit to
secure the other end of the option card to the
threaded standoffs on the CPU board (see

Installation 11
2.8 Battery Replacement
The lithium battery on the CPU board maintains the
real-time clock and protects data stored in the system
RAM when the indicator is not connected to AC power.
Data protected by the CPU board battery includes time
and date, truck and tare memory, onboard database
information, and setpoint configuration.
Use Revolution to store a copy of the indicator
configuration on a PC before attempting battery
replacement. If any data is lost, the indicator
configuration can be restored from the PC.
Watch for the low battery warning on the LCD display
and periodically check the battery voltage on both the
CPU board and on any installed memory option cards.
Batteries should be replaced when the indicator low
battery warning comes on, or when battery voltage falls
to 2.2 VDC. Life expectancy of the battery is ten years.
Replacement Procedure
For best results, replace the battery while in weigh
mode and with AC power applied. Use care not to
bend the battery retaining spring.
If the battery must be replaced with power removed, do
the following immediately after restoring power:
1. Place indicator in setup mode.
2. Go to the Version Menu and press the Reset
Config softkey. If connected using Revolution,
configuration can be reset by using monitor mode
to enter the RESETCONFIGURATION
command followed by the RS command.

3.0 Configuration
To configure the 820i indicator, the indicator must be
placed in setup mode. The setup switch is accessed by
removing the large fillister head screw on the bottom of
the enclosure. Switch position is changed by inserting a
screwdriver into the access hole and pressing the
switch.
When the indicator is placed in setup mode, a series of
menus is shown across the top of the display, along
with the words Scale Configuration. The SCALES menu
is highlighted as the first used to configure the
indicator. Detailed descriptions of these menus are
provided in Section 3.2.
When configuration is complete, press the Exit or Save
and Exit softkey to exit setup mode, then replace the
setup switch access screw.
• The Exit softkey exits setup mode without saving
parameter changes to NV RAM. Changes made
to the configuration remain in the system until
indicator power is cycled.
•Save and Exit writes all parameter changes to NV
RAM before returning to normal mode.
3.1 Configuration Methods
The 820i 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 an indicator serial port. Configuration using the
menus is described in Section 3.1.3.
Configuration using the serial port can be
accomplished using either the serial command set
described in Section 9.0 on page 79 or the Revolution®
configuration utility.
Note Some configuration parameters, such as
those used to configure the 820i display,
cannot be accessed through the
configuration menus. Revolution provides the most
complete and efficient configuration interface for the
820i.
3.1.1 Revolution Configuration
The Revolution configuration utility provides the
preferred method for configuring the 820i 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.
Revolution 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 indicator with an
identical hardware configuration.
To use Revolution, do the following:
1. Install Revolution on an IBM-compatible
personal computer. See Section 5.0 on page 51
for detailed hardware and software
requirements.
2. With both indicator and PC powered off,
connect the PC serial port to the RS-232 pins
on the indicator serial port or to the optional
USB communications card.
3. Power up the PC and the indicator. Use the
setup switch to place the indicator in setup
mode.
4. Start the Revolution program.
Figure 3-1. Revolution Display
Revolution 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.
See Section 5.0 on page 51 for more information about
using Revolution to configure the 820i.

3.1.2 Serial Command Configuration
The serial command set can be used to configure the
820i indicator using either a personal computer,
terminal, or remote keyboard. Like Revolution, serial
command configuration sends commands to the
indicator serial port; unlike Revolution, serial
commands can be sent using any external device
capable of sending ASCII characters over a serial
connection.
Serial commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. Serial commands
can be used to simulate pressing front panel keys, to
configure the indicator, or to dump lists of parameter
settings. See Section 9.0 on page 79 for more
information about using the serial command set.
3.1.3 Front Panel Configuration
Use the CONFIG submenu under the SCALES menu
to configure A/D scales. For example, in an indicator
with a single-channel A/D card installed in Slot 1, the
Scale Configuration display will show the A/D listed
(Slot 1 Channel 1) under the AVAILABLE A/D’s column. Use
the left navigation key to select the A/D, then press the
center softkey, Add. The A/D is then moved to the
Associated A/D’s column. If no other A/D’s are listed
in the AVAILABLE A/D’s column, the center softkey
changes to Done, as shown in Figure 3-2. Press Done to
exit the Scale Configuration display.
See Section 10.3 on page 93 for information about
configuring serial scales.

3.1.4 Multi-Range and Multi-Interval Scales
The 820i supports multi-range and multi-interval scales
of either two or three ranges or intervals.
Multi-range scales provide two or three ranges, each
extending from zero to the maximum capacity
specified for the range, that can specify different scale
intervals (graduations). The scale interval changes as
the applied weight increases but does not reset to lower
range intervals until the scale returns to zero.
Multi-interval scales divide the scale into two or three
partial weighing ranges, each with different scale
intervals. The scale interval changes with both
increasing and decreasing loads applied.
To configure a multi-range or multi-interval scale, use
the SPLIT parameter to select 2RNG or 3RNG (for
multi-range scales), or 2INTVL or 3INTVL (for
multi-interval scales). Selecting a SPLIT value other
than OFF allows specification of decimal point, display
divisions, and maximum capacity for each range or
interval.
The SPLIT parameter is used to enable multi-range or
multi-interval. The SPLIT parameter is in the SCALES
menu, see Figure 3-4, and Table 3-2. After setting the
SPLIT parameter, the Format menu selection will
change as shown in Figure 3-6, and Table 3-4.
If using streaming with multi-range or multi-interval,
the stream must be set to Custom in Revolution. The
Tokens for Secondary and Tertiary Units must be set to
L or K to match the Primary, refer to the Serial Menu,
Tokens Parameter, in Section 3.2.2 on page 30. They
can be set using Revolution or through the front panel.
In multi-range, each range has its own capacity and
display division, extending from zero. The scale
display division will increase at the entered range
capacities, either two or three ranges. Once the range
has increased to the next level, the display division will
remain in new range until the scale returns to zero. The
tare value can be taken in any range.
For example,
Range 1 is 0 - 3000 x 1 lb.
Range 2 is 0 - 10,000 x 5 lb.
In multi-interval, the scale has one capacity, which is
segmented into weighing intervals, either two or three
intervals, each with different display division sizes. As
the weight value exceeds an interval or set interval, the
display division will increase, as the weight falls below
an interval or set interval, the display division will
decrease. The tare can only be taken in the first
interval.
For example,
Range 1 is 0-30 x 0.01 lb.
Range 2 is 30 - 60 x 0.02 lbs.
3.1.5 Total Scale Configuration
The output of A/D scales, serial scales, or iQUBE
systems can be configured to function as a total scale.
Once configured and calibrated, the total scale can be
used as a source for other system functions, including
streaming, setpoints, print formatting, and analog
output.
