About This Manual
This manual is intended for use by service technicians
responsible for installing and servicing
920i
digital
weight indicators.
ConÞguration and calibration of the indicator can be
accomplished using the
iRev
conÞguration utility,
serial commands, or the indicator front panel keys.
See Section 3.1 on page 17 for information about
conÞguration 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

.
The Operator Card included with this manual
provides basic operating instructions for users of the
920i . Please leave the Operator Card with the
indicator when installation and conÞguration are
complete.
1.0 Introduction
The
920i
is a programmable, multi-channel digital
weight indicator/controller. The conÞguration can be
performed using the front panel, with an attached
PS/2
1
-type keyboard, or using the iRev
™
utility.
Custom event-driven programs can be written with the
iRite language up to 128K in program size. These
programs are compiled with an iRev compiler utility,
which can only be downloaded into the indicator. The
RLWS Web Update utility can be used to download
920i Þrmware upgrades to a PC from the RLWS web
site; iRev provides functions for installing the new
software into the 920i .
Onboard Features
Features of the basic 920i include:
¥ Support for A/D scale or serial scale inputs. The
920i
must be conÞgured for at least one scale
inputÑeither from A/D cards or serial input
from an external digital indicator. The maximum
number of scale inputs is 28; these can be
c o m b i n e d t o r e p r e s e n t u p t o 3 2 s c a l e
conÞgurations.
¥ Four digital I/O channels on main board, each
conÞgurable as either input or output.
¥ Four serial ports on main board (Ports 1Ð4)
support duplex RS-232 up to 115200 bps. Port 2
supports hardware handshaking and remote
keyboard input; Ports 3 and 4 support 20mA
o u t p u t ; P o r t 4 s u p p o r t s 2 - w i r e R S - 4 8 5

¥ ConÞgurable print formats can be deÞned for up
to 1000 characters each. These formats are used
to print gross or net weights, truck in/out
weights, setpoint weights, accumulator weights,
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 Þelds for ID number, weight, and the
transaction time and date. Weights can be stored

¥ The setpoint engine has 30 conÞgurable setpoint
kinds. These setpoints can be arranged in a
sequential batch routine of up to 100 steps. If
setpoints are conÞgured as free running
setpoints, they can be tied to program control.
