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
for more information about additional
certifications and approvals.

• 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 types of thermocouple.
• Bus interface cards for Ethernet, EtherNet/IP
