2 820i 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
w e i g h t s , a l e r t m e s s a g e s , a n d h e a d e r
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
types of thermocouple.
• Bus interface cards for Ethernet, EtherNet/IP ™
