1.2 Ov e rvi e w
The 920i is a programmable, multi-channel digital weight indicator/controller. The configuration can be performed
using the front panel, with an attached USB-type keyboard (or PS/2 keyboard if using serial interface), or by using
the iRev 4 utility.
Custom event-driven programs can be written with the iRite language up to 512 K in program size. These programs
are compiled with an iRite compiler utility, which can only be downloaded to the indicator only. The Rice Lake
Weighing Systems Web Update utility can be used to download firmware upgrades to a PC from the Rice Lake
Weighing Systems website; iRev 4 provides functions for installing the new software into the 920i.
Onboard Features
Choice of interface board (serial or USB) affects Port2.
Features of the 920i include:
• Support for A/D scale or serial scale inputs. The maximum number of scale inputs is 28; these can be
combined to represent up to 32 scale configurations.
• Six digital I/O channels on main board, each configurable as either input or output.
• Four serial ports on main board (Ports 1–4) support duplex RS-232 up to 115200 bps. Port 2 supports hardware
handshaking and remote keyboard input, Ports 3 and 4 support 20mA output, Port 4 supports 2-wire RS-485
communications.
• With USB interface card: onboard USB support for a host PC and the following devices: one flash drive, two
printers, and/or one keyboard (connecting more than one device requires a USB hub). The USB interface card
applies only to Port 2.
• With serial interface card: external DB-9 and DIN-8 connectors for serial connection to a PC and attachment of
PS/2 remote keyboard. (cannot be used with the USB card).
• Available in 115 VAC and 230 VAC NorthAmerican and European versions.
Other features include:
• 62K of non-volatile RAM can be allocated to databases using the iRev 4 database editor.
• 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 with iRite.
• 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 language.
The 920i is NTEP-certified for Classes III and III L at 10,000 divisions. See Section 11.14 on page 139 for more
information about additional certifications and approvals.

available option cards and expansion boards are listed in Section 1.7 on page 5.
Front Panel
The 920i front panel, consists of a 27-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. The display
can be graphically configured using iRev 4 software.
Weight information is displayed with a graphical scale in
six font sizes up to 1.2 inches. Up to four scale widgets can
be displayed in Legal-for-Trade, multiple-scale
applications. Status areas on the display are used for
operator prompts and entering data. The remainder of the
display can be graphically configured for representation of
a specific application. Display contrast can be adjusted with
the LCD contrast potentiometer or CONTRAST parameter.
Enclosures
The 920i is available in four enclosures: universal (tilt-
stand), deep enclosure, panel mount, and wall mount.
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 and wall mount models.
1.3 Operating Modes
The 920i has two modes of operation:
Weigh mode
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 920i 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 non-conductive tool into
the access hole and press the setup switch once. The indicator displays scale configuration menus.

shield as described below:
• For cables with foil shielding, strip insulation and foil
from the cable 1/2 inch (15 mm) past the grounding
clamp, see Figure 2-2. 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 1/2 inch (15 mm) of insulation
only to expose the braid where the cable passes through the clamp, see Figure 2-2.
• For load cell cables, cut the shield wire just past the grounding clamp. Shield wire function is provided by
contact between the cable shield and the grounding clamp.
• Route stripped cables through cord grips and clamps. Ensure shields contact grounding clamps as shown in
Figure 2-2. Tighten grounding clamp nuts.
• Finish installation using cable ties to secure cables inside of indicator enclosure.
2.3.3 Load Cells
To attach the cable from a load cell or j-box to an installed A/D card, route the cable through the cord grip and
ground the shield wire as described in Section 2.3.2 on page 9.
Remove connector J1 from the A/D card. The connector plugs into a header on the A/D card, see Figure 2-3. Wire
the load cell cable from the load cell or j-box to connector J1 as shown in Table 2-1.
If using 6-wire load cell cable (with sense wires), remove jumpers JP1 and JP2 before reinstalling connector J1. For
4-wire installation, leave jumpers JP1 and JP2 on. For 6-wire load cell connections on dual-channel A/D cards,
remove jumpers JP3 and JP4 for connections to J2.
When connections are complete, reinstall load cell connector on the A/D card and use two cable ties to secure the
load cell cable to the inside of the enclosure.

2.3.4 Serial Communications
The four communications ports on the 920i CPU board support full duplex RS-232, 20 mA output, or RS-485
communications at up to 115200 bps.
To attach serial communications cables:
1. Route the cable through the cord grip.
2. Ground the shield wire as described in Section 2.3.2 on page 9.
3. Remove the serial connector from the CPU board and wire to the connector.
4. Once cables are attached, plug the connector into the header on the board.
5. Use cable ties to secure serial cables to the inside of the enclosure.
Table 2-2 shows the pin assignments for Ports 1, 3, and 4. Port 2 provides DIN-8 and DB-9 connectors for remote
keyboard attachment of PS/2-type personal computer keyboards. The DB-9 connector pin assignments for Port 2
are shown in Table 2-3; see Section 11.3 on page 123 for information about the PS/2 keyboard interface.
Serial ports are configured using the SERIAL menu. See Section 3.2.2 on page 36 for configuration information.
An optional dual-channel serial communications expansion card, PN 67604, is available. Each serial expansion
card provides two additional serial ports, including one port that supports RS-485 communications. Both ports on
the expansion card can support RS-232 or 20mAconnections.

2.3.5 USB Communications (Port 2)
The USB interface provides type-A and type-B connectors.
Compatible devices using a type-A connector include a flash
drive, keyboard, USB hub, and label and ticket printers. The host
PC uses a type-B connector.
2.3.6 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.
Digital inputs and outputs are configured using the DIG I/O menu. See Section 3.2.6 on page 51 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 DigInSsBbActivate handler. 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.
