1.2 Overview
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 Rice Lake Weighing Systems Web Update utility can be
used to download 820i firmware upgrades to a PC from the Rice Lake Weighing Systems 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 12.0 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.

Front Panel
The 820i front panel, shown in Figure 1-1, consists of a 28-button keypad with a large backlit LCD display. The keys are
grouped as five configurable softkeys, five primary scale function keys, four navigation keys, and numeric entry keys.
Weight information is displayed with a graphical scale in two font sizes. Status areas on the display are used for operator
prompts and entering data.
LCD display contrast and backlighting can be adjusted using the Display button on the front panel.
Figure 1-1. 820i Front Panel
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 1.6).
1.3 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.
1.4 Indicator Operations
Basic 820i operations are summarized in the following sections.
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.

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 43 for configuration information.
An optional 24-channel digital I/O expansion card, PN 67601, is available for applications requiring more digital I/O channels.
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.
Option cards are not hot-pluggable. Disconnect power to the 820i before installing option cards.
General installation of options cards:
1. Disconnect power to the indicator.
2. Remove backplate as described in Section 2.2.
3. Carefully align the large option card connector with connector J6 on the CPU board (see Figure 2-3) or J1.
4. Press down to seat the option card in the CPU board connector.
5. Use the screws provided in the option kit to secure the option card to the threaded standoffs on the CPU board (see
Figure 2-3).
6. Make connections to the option card as required.
7. Use cable ties to secure loose cables inside the enclosure.
8. Reassemble the enclosure as described in Section 2.6.
The 820i automatically recognizes all installed option cards when the unit is powered on. No hardware-specific configuration is
required to identify the newly-installed card to the system.

2.5 Slot Assignments
Table 2-4 lists the slot numbers, CPU board connectors, and configuration assignments made for both onboard and expansion
card functions in the 820i. See Figure 2-3 for connector locations.
2.6 Enclosure Reassembly
Once cabling is complete, position the backplate over the enclosure and reinstall the backplate screws. Use the torque pattern
shown in Figure 2-4 to prevent distorting the backplate gasket. Torque screws to 15 in-lb (1.7 N-m).
Figure 2-4. 820i Enclosure Backplate
Torqued screws may become less tight as the gasket is compressed during torque pattern, therefore a second
torque is required using the same pattern and torque value.
2.7 CPU Board Removal
Removing the 820i CPU board:
1. Disconnect power to the indicator.
2. Remove backplate as described in Section 2.2.
3. Unplug connectors for power to the board, serial communications, digital I/O, and any installed option cards.
4. Remove any installed option cards.
5. Remove the five Phillips head screws and two kep nuts from the CPU board.
6. Gently lift up the CPU board, then disconnect bottom-side connectors for power to display, ribbon cable, and keypad
connector.
7. Remove CPU board from the enclosure. If necessary, cut cable ties to shift cables out of the way.
To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to secure all cables inside the indicator
enclosure.
