920i Installation Manual
About This Manual
This manual is intended for use by service technicians
responsible for installing and servicing 920i™ digital
weight indicators. This manual applies to Version 1.05
of the 920i indicator software.
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 20 for information about
conÞguration methods.
1.0
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 www.rlws.com.
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.
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
combined to represent up to 32 scale
conÞgurations.
¥ Four digital I/O channels on main board, each
conÞgurable as either input or output.
¥ Four serial ports on main board (Ports 1Ð4)

Enclosures
The 920i is available in four enclosures: universal
(tilt-stand), desktop, panel mount, and wall mount.
Stainless steel enclosures are rated for NEMA
4X/IP66. This manual provides assembly drawings
and replacement parts lists for the universal and
desktop models; supplemental documentation
provides information speciÞc to the panel mount and
wall mount models (Section 1.4 on page 4).
1.1
Operating Modes
The 920i 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 conÞguration is complete
and a legal seal is afÞxed to the large Þllister-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 conÞguration and calibration.
To enter setup mode, remove the large Þllister
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 conÞguration
menus.
1.2
Indicator Operations
Basic 920i operations are summarized below:
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.
1.3
Softkey Operations
Softkeys can be deÞned to provide additional operator
functions for speciÞc applications. Softkey assignments
are listed on the tabs shown at the bottom of the LCD
display; softkey functions are activated by pressing the
arrow keys below the softkey tabs (Figure 1-1 on page

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.

If you must remove the 920i CPU board, use the
following procedure:
1. Disconnect power to the indicator. Remove
backplate as described in Section 2.2 on
page 6.
2. Unplug connectors J9, J10, and J11 (serial
communications), J2 (digital I/O), P1 (power
supply), and connectors to any installed
option cards.
3. Remove any installed option cards.
4. Remove the Þve phillips head screws and two
kep nuts from the CPU board.
5. Gently lift up the CPU board, then disconnect
connectors J12 (power to display), J4 (ribbon
cable, J3 (keypad connector), then the cable
J8 (Port 2 serial port).
6. 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.
Table 2-5. Expansion Board Serial Port Assignments
For example, in a system with a two-card expansion
board, port assignments are reserved as shown in
Figure 2-10. If the only serial card installed in this
system is in SLOT 4 of the expansion board, the
system consists of serial ports 1Ð4 (on the CPU board)
and ports 11Ð12.

Fuse Replacement
Fuses for the desktop and universal models of the 920i
are located under a cover plate on the outside of the
enclosure. Remove the cover plate, replace the fuses,
and reinstall the cover plate (see Figures 2-12 and
2-13).
Caution
To protect against the risk of fire,
replace fuses only with same type and
rating fuse.
See Section 10.13 on page 107 for complete fuse
speciÞcations for the desktop and universal units.
Caution
Interface board and fuse access cover
plates must be in place for use in
NEMA 4X/IP66 applications.
Torque fuse and interface board access covers to
8 in-lb (0.90 N-m)
Use iRev to store a copy of the indicator conÞguration
on a PC before attempting battery replacement. If any
data is lost, the indicator conÞguration can be restored
from the PC.
NOTE: Memory option card data is also protected by a
lithium battery. All database information stored on a
memory card is lost if the memory card battery fails.
Watch for the low battery warning on the LCD display
and periodically check the battery voltage on both the
CPU board and on any installed memory option cards.
Batteries should be replaced when the indicator low
battery warning comes on, or when battery voltage
falls to 2.2 VDC. Life expectancy of the battery is ten
years.
See Figure 2-4 on page 8 for CPU board battery
location and orientation (positive side up).
Caution
Risk of explosion if battery is replaced
with incorrect type. Dispose of
batteries per manufacturer instruction.

Configuration
To conÞgure the 920i indicator, the indicator must be
placed in setup mode. The setup switch is accessed by
removing the large Þllister head screw on the desktop
and universal enclosures. Switch position is changed
by inserting a screwdriver into the access hole and
pressing the switch.
When the indicator is placed in setup mode, a series of
menus is shown across the top of the display, along
with the words Scale Configuration . The SCALES
menu is highlighted as the Þrst used to conÞgure the
indicator. Detailed descriptions of these menus are
provided in Section 3.2.
When conÞguration is complete, press the Exit or
Save and Exit softkey to exit setup mode, then replace
the setup switch access screw.
¥ The Exit softkey exits setup mode without
saving parameter changes to NV RAM. Changes
made to the conÞguration remain in the system
until indicator power is cycled.
¥ Save and Exit writes all parameter changes to
NV RAM before returning to normal mode.
3.1
Configuration Methods
The 920i indicator can be conÞgured by using the
front panel keys to navigate through a series of
conÞguration menus or by sending commands or
conÞguration data to an indicator serial port.
ConÞguration using the menus is described in
Section 3.1.3.
ConÞguration using the serial port can be
accomplished using either the serial command set
described in Section 9.0 or the iRev conÞguration
utility.
NOTE: Some conÞguration parameters, such as those
used to conÞgure the 920i display and widgets, cannot
be accessed through the conÞguration menus. iRev
provides the most complete and efÞcient conÞguration
interface for the 920i.
3.1.1
iRev Configuration
The iRev conÞguration utility provides the preferred
method for conÞguring the 920i indicator. iRev runs
on a personal computer to set conÞguration
parameters for the indicator. When iRev conÞguration
is complete, conÞguration data is downloaded to the
indicator.
iRev supports both uploading and downloading of
indicator conÞguration data. This capability allows
conÞguration data to be retrieved from one indicator,
edited, then downloaded to another indicator with an
identical hardware conÞguration.
20
920i Installation Manual
Figure 3-1. iRev Hardware ConÞguration Display
To use iRev, do the following:
1. Install iRev on an IBM-compatible personal
computer. See Section 5.0 on page 44 for
detailed hardware and software requirements.
2. With both indicator and PC powered off,
connect the PC serial port to the RS-232 pins
on the indicator serial port.
3. Power up the PC and the indicator. Use the
setup switch to place the indicator in setup
mode.
4. Start the iRev program.
iRev provides online help for each of its conÞguration
displays. Parameter descriptions provided in this
manual for front panel conÞguration can also be used
when conÞguring the indicator using iRev : The
interface is different, but the parameters set are the
same.
See Section 5.0 on page 44 for more information about
using iRev to conÞgure the 920i.
3.1.2
Serial Command Configuration
The serial command set can be used to conÞgure the
920i indicator using either a personal computer,
terminal, or remote keyboard. Like iRev , serial
command conÞguration sends commands to the
indicator serial port; unlike iRev, serial commands can
be sent using any external device capable of sending
ASCII characters over a serial connection.
Serial commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. Serial commands
can be used to simulate pressing front panel keys, to
conÞgure the indicator, or to dump lists of parameter
settings. See Section 9.0 on page 72 for more
information about using the serial command set.
3.1.3
Front Panel Configuration
Use the CONFIG submenu under the SCALES menu
to conÞgure A/D scales. For example, in an indicator
with a single-channel A/D card installed in Slot 1, the
Scale ConÞguration display will show the A/D listed
(Slot 1 Channel 1) under the AVAILABLE A/D’s column.
Use the left navigation key to select the A/D, then
press the center softkey, Add. The A/D is then moved
to the Associated A/DÕs column. If no other A/DÕs are
listed in the AVAILABLE A/D’s column, the center
softkey changes to Done , as shown in Figure 3-2.
Press Done to exit the Scale ConÞguration display.
See Section 10.4 on page 91 for information about
conÞguring serial scales.
Figure 3-2. Scale ConÞguration Display
The 920i indicator can be conÞgured using a series of menus accessed through the indicator front panel when the
indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.

NOTE: The maximum total sample rate for all configured A/D channels—the sum of the
sample rates for all scales—is 1200 Hz. For example, up to ten scales can be configured
with 120 Hz sample rates, or up to twenty scales with 60 Hz sample rates.
In DELAY mode, the indicator performs a power up display test, then enters a 30-second

Description
Multiplier. Specifies the conversion factor by which the primary units are multiplied by to
obtain the displayed rate of change units.
To calculate the MULT value, use the following equation:
MULT = (SMPRAT / INTERVL) * (seconds_per_ROC_unit) * (ROC/PRIMAR_precision_adjustment)
Where:
• SMPRAT is the value specified for the A/D sample rate on the SCALES menu
• INTERVL is the specified ROC interval
• seconds_per_ROC_unit is an adjustment for the ROC UNITS parameter. If ROC UNITS
is set to SEC, use 1; use 60 for UNITS=MIN, use 3600 for UNITS=HOUR.
• ROC/PRIMAR_precision_adjustment compensates for any difference in the DECPNT
and DSPDIV parameters specified for primary units and ROC units. For example, if the
ROC DECPNT parameter is set to 8888888 (no decimal) and with DSPDIV=1, ROC
precision is 1. If PRIMAR DECPNT is set to 8888880 (null units position) and
DSPDIV=2, PRIMAR precision is 20. (That is, weights will be displayed in increments of
20.) In this example, the precision adjustment would be 1 / 20, or 0.05.
Example: If SMPRAT=120HZ, INTERVL=240, ROC UNITS=MIN, and the precision is
compensated as described above, MULT would be calculated as follows:
MULT = (120 / 240) * 60 * 0.05 = 1.5
To calculate a ROC MULT value based on secondary or tertiary units, multiply the calculated
primary units MULT value by the conversion factor for the alternate units. For example, if a
MULT value of 1.5 is calculated for pounds as the primary unit, calculate the MULT value for
kilogram secondary units by multiplying the original MULT value by 0.453592:
MULT(kg) = 1.5 * 0.453592 = 0.680388

The value specified for this parameter should be an integer not less than 1% and not more

parameter value is 120, the REFRESH specified should be in the range of 2–60.

softkey to calibrate span. When complete, the
new A/D count for the span calibration is
displayed. Press enter again to save the span
calibration value and go to the next prompt
(WLIN).
6. Five-point linearization (using the WLIN
parameter) provides increased scale accuracy
by calibrating the indicator at up to Þve
additional points between the zero and span
calibrations.
Linearization is optional: if you choose not to
perform linearization, skip the WLIN
parameter; if linearization values have
previously been entered, these values are reset
to zero during calibration. To perform
linearization, follow the procedure below:
With WLIN displayed, Press down to go to the
Þrst linearization point (POINT 1). Press

serial port pin assignments; see Section 9.0 on
page 72 for more information about using serial
commands.
Once the indicator is connected to the sending device,
do the following:
1. Place the indicator in setup mode (display
reads CONFIG) and remove all weight from
the scale platform. If your test weights require
hooks or chains, place the hooks or chains on
the scale for zero calibration.
2. Send the SC.WZERO#n serial command
(where n is the number of the scale) to
calibrate zero.
3. Place test weights on the scale and use the
SC.WVAL command to enter the test weight
value in the following format:
SC.WVAL#n=vvvvv<CR>
4. Send the SC.WSPAN#n serial command to
calibrate span.
5. Up to Þve linearization points can be calibrated
between the zero and span calibration values.
Calibration
41
Use the following commands to set and
calibrate a single linearization point:
SC.WLIN#n.V1=vvvvv<CR>
SC.WLIN#n.C1<CR>
The SC.WLIN#n.V1 command sets the test
weight value (vvvvv) for linearization point 1.
The SC.WLIN#n.C1 command calibrates the
point. Repeat using the SC.WLIN#n.Vx and
SC.WLIN#n.Cx commands as required for
additional linearization points.
6. To remove an offset value, clear all weight
from the scale, including hooks or chains used
to hang test weights, then send the

Configuring Other Parameters
Once the scale source is set, you can continue
conÞguring the scale using the other icons listed under
the System Parameters , or you can use the Scale
Wizard (shown as a button on the Scales menu; also
available under the Tools menu) to create a basic
conÞguration based on your application type, units,
capacity, and Þltering requirements.
Other subsets of conÞguration parameters, including
stream, print, and display formatting, can be accessed
by selecting them from the list shown at the left side
of the iRev displays.
5.3.2
Configuring the Display
The iRev display editor allows the 920i display to be
customized by dragging and dropping widgets onto a
virtual display, then setting parameters speciÞc to
each widget type. (See Section 9.2 on page 82 for
detailed information about widget programming.) Up
to ten display conÞgurations can be saved for each
indicator Þle. Display conÞgurations can be switched
within applications using custom programs to drive
the 920i.
Setpoints
The Setpoints menu, available by clicking the
Setpoints icon under System Parameters, provides
access to all conÞguration parameters for up to 100
setpoints. ConÞgured setpoints can be displayed
individually or in groups of 5, 10, or 100; setpoint
parameters can be changed only when shown
individually. Click on the setpoint view icons in the
toolbar to change the view.

Connecting to the Indicator
Connect the PC serial port to port 2 of the 920i. Return
to the Hardware ConÞguration display, then click on
the Connect icon in the toolbar. iRev attempts to
establish communications to the indicator.
Once communications is established, iRev queries the
indicator conÞguration to determine whether the
indicator hardware matches the virtual hardware
conÞgured in the current iRev Þle. If the hardware
matches, the Hardware ConÞguration section of iRev
is disabled, preventing further changes.
If the hardware does not match, you are given the
option of either canceling the connect operation or
overwriting the iRev hardware conÞguration with the
actual indicator hardware conÞguration.
Downloading to the Indicator
The Download Configuration function on the iRev
Communications menu allows an iRev conÞguration
system software requires a RESETCONFIGURATION
function and resets all conÞguration and calibration values
to their factory defaults.

The Download Current Display function on the
Communications menu allows you to download only
the currently displayed object, such as the parameter
set for one scale of a multi-scale conÞguration.
Because less data is transferred using Download
Current Display, it is typically faster than a full
conÞguration download, but there is an increased
possibility that the download may fail due to
dependencies on other objects. If the download fails,
try performing a complete download using the

Print Formatting
The 920i provides seven print formats that determine the format of the printed output when the PRINT key is
pressed, a KPRINT serial command is received, or when setpoint push-print or truck weigh-in or weigh-out
operations are performed. Supported print formats are: GFMT, NFMT, ACCFMT, SPFMT, TRWIN, TRWOUT,
and AUXFMT. Additionally, two header formats, HDRFMT1 and HDRFMT2, can be inserted into any of the
other ticket formats using the <H1> and <H2>formatting commands. The particular ticket format used for a
given print operation depends on the indicator conÞguration (see Table 6-2 on page 49) and the particular
operation performed.
Each print format can be customized to include up to 1000 characters of information, such as company name and
address, on printed tickets. You can use the iRevª conÞguration utility, serial commands, or the indicator front panel
(PFORMT menu) to customize the print formats.

Customizing Print Formats
The following sections describe procedures for
customizing print formats using the iRev conÞguration
utility, serial commands, or the front panel (PFORMT
menu. See Section 10.5 on page 91 for information
about custom stream formatting.
6.3.1
Figure 6-1 shows an example of the iRev print
formatting display.
Using iRev
The iRev conÞguration utility provides a ticket
formatting grid with a tool bar. The grid allows you to
construct the ticket format without using the
formatting commands (<NL> and <SP>) required by
the front panel or serial command methods. Using
iRev , you can type text directly into the grid, then
select weight value Þelds from the tool bar and place
them where you want them to appear on the printed
ticket.

Using the Front Panel
If you have no access to equipment for communication through a serial port or are working at a site where such
equipment cannot be used, you can use the PFORMT menu (see Figure 6-2 on page 50) to customize the print
formats.

Each print format can be edited from the front panel
using a character selection like that shown in
Figure 6-3. Use the navigation keys (up, down, left,
right ) to move around and between the format
command line and the character selection list.
Figure 6-3. Print Formatting Character Selection Display
¥ To add a character: position the cursor in the
format where you want to add the character. Use
the up key to return to the character selection
list, use the navigation keys to highlight the
character to add, then press enter. The new
character is added to the left of the current
cursor location in the format string.
¥ To add a blank space to a string, position the
cursor to the right of where the space is to be
inserted in the format string, highlight the SP
character in the selection list, and press enter.
50
920i Installation Manual
¥ To delete a character, position the cursor to the
right of the character to be deleted from the
format string, then press the CLR key.
¥ To add a special character, insert the < and >
delimiter characters from the selection list. Use
the numeric keypad to insert the decimal ASCII
value (1Ð255) of the character between the
delimiters. For example, insert <2> to add the
STX character to the print format.
To save the edited format string, position the cursor in
the format string and press enter. Softkeys shown on
the character selection display provide additional
functions:
Default
Restores the string to its default value.
Home
Positions cursor at the beginning of the
format string.
Cancel
Exits without saving changes to the
format string.
End
Positions cursor at the end of the format
string.
Restore
Restores the string to its previously
saved value.
A Print Test softkey is shown under the FMT
parameter after exiting the character selection display.
If a printer is attached, this key can be used to verify
the edited string format before exiting setup mode.
NOTE: The Print Test softkey is not available for the
HDRFMTx formats. These formats can be output only
when inserted into one of the printable ticket formats by
using the <H1> or <H2> print format commands.
6.3.3
Using Serial Commands
With a personal computer, terminal, or remote keyboard attached to one of the 920i serial ports, you can use the
serial command set described in Table 6-1 on page 47 to customize the print format strings.
To view the current setting of a format string, type the name of the print format and press the enter key. For
example, to check the current conÞguration of the GFMT format, type GFMT.FMT and press enter. The
indicator responds by sending the current conÞguration for the gross format:
GFMT.FMT=<G> GROSS<NL>
To change the format, use the GFMT.FMT or NFMT.FMT serial command followed by an equals sign (=) and
the modiÞed print format string. For example, to add the name and address of a company to the gross format, you
could send the following serial command:
GFMT.FMT=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>
A ticket printed using this format might look like the following:
MOE'S DUMP
2356 EAST HIGHWAY ROAD
SMALLTOWN
1345 LB GROSS
The ticket above could also be formatted by specifying the company address information in the HDRFMT1
ticket format, then substituting the <H1> command for the address in the GFMT ticket format:
HDRFMT1=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2>
GFMT.FMT=<H1><G> GROSS<NL>

Truck Modes
The truck in/out modes are used to handle multiple
truck ID numbers and weights. Six truck modes
combine stored ID, keyed tare, and value swapping

Table 7-1. Truck Mode Features
Stored IDs let you keep a database of truck IDs and
weigh-in weights in the indicatorÕs memory. The
indicator can automatically store up to 1000 truck IDs
and tares; or it can clear the information after printing
a weigh-out ticket. For example, if the same truck
seldom crosses the scale, it may not be practical to
save its ID number and weigh-in weight. However, if
that same truck crosses the scale many times each day,
itÕs more convenient to store the information in the
indicator memory and recall it when needed. Stored
IDs and weights are available in modes 3, 4, 5, and 6.
Keyed tares allow you to manually enter the tare
weight using the numeric keypad and the TARE key.
Keyed tares are available in modes 1, 3, and 5. To use
keyed tares, an incoming truck must be empty at
weigh-in, full at weigh-out.
NOTE: Some local regulations require the tare weight
to be read from the scale. If so, donÕt use the keyed
tares feature.
Value swapping ensures that the lowest of two
weight values associated with a particular ID number
is entered as the tare weight. For example, if a truck
crosses the scale fully loaded at weigh-in, then
unloads and crosses the scale empty at weigh-out, the
indicator automatically assigns the lesser (empty
truck) weight as the tare. Value swapping is available
in modes 1, 2, 3, and 4.

Using the Truck Modes
To select a truck in/out mode, press the setup switch to
enter setup mode. Use the navigation keys to go to the
FEATURE menu, then to the TRUCK submenu to
select the mode.

Using the Truck Regs Display
The Truck Regs display is shown by pressing the
Truck Regs softkey in weighing mode. The display
contains an alphabetical list of stored truck IDs,
weigh-in weights (in primary units), and the time and
date of the weigh-in transaction (see Figure 7-2).
Figure 7-2. Truck Register Display
Softkeys shown at the bottom of the Truck Regs
display are described below.
Page Up

register.
Page Down Shows next page of the truck register.
Cancel
Exits to weighing mode.
Delete
Deletes the highlighted truck ID from
the truck register.
Delete All Deletes all truck IDs from the truck
register.
The truck register can be printed to an attached printer
by pressing the PRINT key while the Truck Regs
display is shown. The printed register uses the
TRFMT print format (see Section 6.2 on page 49).
NOTE: If a non-zero setpoint password is configured
(SPPWD parameter on the FEATURE menu), you must
enter the password before any truck register entries
can be deleted.
7.3
Weigh-In Procedure
In modes 1 and 2, the indicator erases truck ID
numbers and tare weights from memory after the
transaction. In modes 3Ð6,the truck ID and weigh-in
weight values are saved after the weigh-out ticket has
been processed.
The general weigh-in procedure is as follows:
1. The empty truck moves onto the scale for
weigh-in.
2. Press the Weigh In softkey.
3. A prompt is shown to enter the truck ID (up to
eight alphanumeric characters). Enter the ID,
then press the enter key.
4. Indicator generates the weigh-in ticket:

Single-Transaction Tare Weights
and IDs
One-time transactions are supported in all modes that
can be conÞgured to use stored IDs (modes 3Ð6). This
function allows one-time weighing of trucks without
adding the truck ID and weigh-in weight to the
permanent truck register.
To use this function, enter a truck ID containing a
decimal point, then press the Weigh In softkey. IDs
entered with a decimal point as part of the ID are
erased from the truck register when the transaction is
complete.

7.4
Weigh-Out Procedure
The general weigh-out procedure is as follows:
1. The loaded truck moves onto the scale for
weigh-out.
2. If truck ID is known, press the Weigh Out
softkey, enter the ID, and press the enter key.
If ID is not known, press the Truck Regs
softkey to view list of stored IDs (see
Figure 7-2 on page 52). Scroll to the correct
truck ID, note the ID number, then press the
Cancel softkey to return to the weight display.
From the weight display, press Weigh Out,
key in the ID, then press the enter key.
3. Indicator generates the weigh-out ticket. In
modes 1 and 2, the ID is deleted once the
weigh-out ticket is processed.

Setpoints
The 920i indicator provides 100 conÞgurable setpoints for control of both indicator and external equipment
functions. Setpoints can be conÞgured to perform actions or functions based on speciÞed parameter conditions.
Parameters associated with various setpoint kinds can, for example, be conÞgured to perform functions (print,
tare, accumulate), to change the state of a digital output controlling indicator or external equipment functions, or
to make conditional decisions.
8.1
Batch and Continuous Setpoints
920i setpoints can be either continuous or batch setpoints.
Continuous setpoints are free-running: the indicator constantly monitors the condition of free-running setpoints
at each A/D update. The speciÞed setpoint action or function is performed when the designated setpoint
parameter conditions are met. A digital output or function assigned to a free-running setpoint continuously
changes state, becoming active or inactive, as deÞned by the setpoint parameters.
Batch setpoints are active one at a time, in an ordered sequence. The 920i can use setpoints to control up to 100
separate batch processing steps.
A digital output associated with a batch setpoint is active until the setpoint condition is met, then latched for
the remainder of the batch sequence.
To use batch setpoints, you must activate the BATCHNG parameter on the SETPTS menu. This parameter
deÞnes whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, while
MANUAL sequences require a BATSTRT signal. The BATSTRT signal can be initiated by a digital input,
serial command, Batch Start softkey, or the StartBatch function in an iRite program.
For setpoint kinds that can be used as either continuous or batch setpoints, the BATCH parameter must also
be set ON. (Setpoint kinds that can only be used as batch setpoints do not require the BATCH parameter.) If
the setpoint is deÞned but the BATCH parameter is off, the setpoint operates as a continuous setpoint, even
during batch sequences.
NOTE: In applications that contain both batch setpoint routines and continuous setpoints, continuous setpoints
should be kept separate from the batch sequence. This is especially true when using CONCUR or TIMER
setpoints to perform actions or functions based on the batch sequence. CONCUR and TIMER setpoints should
not be included in the referenced START and END setpoint sequence.

ACCUM
Accumulate setpoint. Compares the value of the setpoint to the source scale
accumulator. The accumulator setpoint is satisfied when the value of the source
scale accumulator meets the value and conditions of the accumulator setpoint.
Ö
Ö
ROC
Rate-of-change setpoint. Performs functions based on the rate-of-change
(ROC) value.
Ö
Ö
+REL
Positive relative setpoint. Performs functions based on a specified value above
a referenced setpoint, using the same weight mode as the referenced setpoint.

–REL
Negative relative setpoint. Performs functions based on a specified value below
a referenced setpoint, using the same weight mode as the referenced setpoint.
Ö
Ö
%REL
Percent relative setpoint. Performs functions based on a specified percentage
of the target value of a referenced setpoint, using the same weight mode as the
referenced setpoint. The actual target value of the %REL setpoint is calculated
as a percentage of the target value of the referenced setpoint.
Ö
Ö
RESREL
Relative to a result setpoint. Performs functions based on a specified
percentage of the captured value of a referenced setpoint, using the same
weight mode as the referenced setpoint. The actual target value of the RESREL
setpoint is calculated as a percentage of the captured value of the referenced
setpoint, rather than the target value.
Ö
Ö
PAUSE
Pauses the batch sequence indefinitely. A BATSTRT signal must be initiated to
continue the batch process.
Ö
DELAY
Delays the batch sequence for a specified time. The length of the delay (in
tenths of a second) is specified on the VALUE parameter.
Ö
WAITSS
Wait for standstill. Suspends the batch sequence until the scale is at standstill.
Ö
COUNTER
Specifies the number of consecutive batch sequences to perform. Counter
setpoints should be placed at the beginning of a batch routine.
Ö
AUTOJOG
Automatically checks the previous weight-based setpoint to verify the setpoint
weight value is satisfied in a standstill condition. If the previous setpoint is not
satisfied when at standstill, the AUTOJOG setpoint activates the digital output
of the previous weight-based setpoint for a period of time, specified on the
VALUE parameter. The autojog process repeats until the previous weight-based
setpoint is satisfied when the scale is at standstill.
Ö
NOTE: The AUTOJOG digital output is typically used to signify that an autojog
operation is being performed. AUTOJOG should not be assigned to the same
digital output as the related weight-based setpoint.
COZ
Center of zero. Monitors for a gross zero condition. The digital output
associated with this setpoint kind is activated when the referenced scale is a
center of zero. No value is required for this setpoint.
Ö
INMOTON
In motion. Monitors for an in-motion condition. The digital output associated
with this setpoint is activated when the scale is not at standstill. No value is
required for this setpoint.
Ö
INRANGE
In range. Monitors for an in-range condition. The digital output associated with
this setpoint is activated when the scale is within capacity range. No value is
required for this setpoint.
Ö
BATCHPR
Batch processing signal. The digital output associated with this setpoint is
activated whenever a batch sequence is in progress. No value is required for
this setpoint.
Ö
TIMER
Tracks the progress of a batch sequence based on a timer.
Ö
The timer value, specified in tenths of a second on the VALUE parameter,
determines the length of time allowed between start and end setpoints. The
indicator START and END parameters are used to specify the start and end
setpoints. If the END setpoint is not reached before the timer expires, the digital
output associated with this setpoint is activated.

CONCUR
Description
Batch
Continuous
Ö
Allows a digital output to remain active over a specified portion of the batch
sequence. Two types of concur setpoints can be configured:
Type 1 (VALUE=0): The digital output associated with this setpoint becomes
active when the START setpoint becomes the current batch step and remains
active until the END setpoint becomes the current batch step.
Type 2 (VALUE > 0): If a non-zero value is specified for the VALUE parameter, that
value represents the timer, in tenths of a second, for this setpoint. The digital
output associated with this setpoint becomes active when the START setpoint
becomes the current batch step and remains active until the timer expires.
NOTE: If more than one concurrent setpoint is configured, each must be
assigned to a different digital output.
DIGIN
Digital input setpoint. Requires a specific group of digital inputs to be in low (0
VDC) state to satisfy the setpoint. The digital output associated with this
setpoint is held in a low (0 VDC) state until the inputs selected for the digital
input mask are all in a low state.
Ö
Ö
AVG
Average setpoint. Performs functions based on the calculated average weight
over a specified number of A/D samples.
Ö
Ö
Ö
Note that this setpoint is based on the raw A/D weight value, rather than the
rounded value shown on the indicator display. For example, if the display shows
50.0 but the actual raw A/D value is 49.99, the setpoint will not be satisfied.
TOD
Time of day setpoint. Performs functions when the internal clock time of the
indicator matches the specified setpoint time.
Ö
DELTA
Delta weight setpoint. Satisfied when the change in weight on the scale is equal
to or exceeds the absolute value specified for the setpoint.
Ö
CHKWEI
Checkweigher setpoint. Allows specification of over- and under-weight values.
Up to three digital outputs can be configured to represent overweight,
underweight, and accept conditions.
PLSCNT
Pulse counter setpoint. Performs functions based on pulse counts received by
a pulse input card.
PLSRAT
Pulse rate setpoint. Performs functions based on the pulse rate received by a
pulse input card.
ALWAYS
Always setpoint. This setpoint is always satisfied. It is typically used to provide
an endpoint for true/false branching batch routines.
Ö
NEVER
Never setpoint. This setpoint is never satisfied. It is used to branch to a
designated setpoint in true/false branching batch routines in which the batch
will not continue through the normal sequence of batch setpoints.

VALUE
number
Setpoint value.
• For weight-based setpoints: Specifies the target weight value, 0–9999999.
• For time-based setpoints: Specifies, in 0.1-second intervals, a time value in the
range 0–65535.
• For COUNTER setpoints: Specifies the number of consecutive batches to be run,
0–65535.
• For PLSCNT setpoints, specifies a number of pulses, 0-65535, received by a
pulse input card.
• For PLSRAT setpoints, specifies a pulse rate in Hz, 0-65535, received by a pulse
input card.
TRIP
HIGHER
LOWER
INBAND
OUTBAND
Specifies whether the setpoint is satisfied when the weight is higher or lower than the
setpoint value, within a band established around the value, or outside of that band.
BANDVAL
0–9999999
For setpoints with TRIP=INBAND or OUTBAND, specifies a weight equal to half the
band width. The band established around the setpoint value is VALUE ±BANDVAL.
HYSTER
0–9999999
Specifies a band around the setpoint value that must be exceeded before the
setpoint, once off, can trip on again.
PREACT
OFF
ON
LEARN
FLOW
Allows the digital output associated with a setpoint to shut off before the setpoint is
satisfied to allow for material in suspension.
The ON value adjusts the setpoint trip value up or down (depending on the TRIP
parameter setting) from the setpoint value.
The LEARN value can be used to automatically adjust the preact value after each
batch. LEARN compares the actual weight at standstill to the target setpoint value,
then adjusts the preact by half of the difference after each batch.
FLOW preact provides compensation for material flow rate in determining when to
shut off the digital output. Rather than waiting for the specified weight to be reached,
FLOW preact uses the change in weight over time to anticipate when the preact
weight value will be reached.
PREVAL
0–9999999
Specifies the preact value for setpoints with PREACT set to ON, LEARN, or FLOW.
Depending on the TRIP setting specified for the setpoint, the setpoint trip value is
adjusted up or down by the preact value.
PREADJ
0.500000
0–9999999
Preact adjustment factor. For setpoints with PREACT set to LEARN or FLOW,
specifies a decimal representation of the percentage of error correction applied (0.5
= 50%, 1.0 = 100%) each time a preact adjustment is made.
PRESTAB
0
0–65535
Time-out for preact learn. For setpoints with PREACT set to LEARN or FLOW,
specifies the time, in 0.1-second intervals, to wait for standstill before adjusting the
preact value. Setting this parameter to a value greater than zero disables the learn
process if standstill is not achieved in the specified interval.
PCOUNT
1
0–65535
Preact learn interval. For setpoints with PREACT set to LEARN or FLOW, specifies
the number of batches after which the preact value is recalculated. The default value,
1, recalculates the preact value after every batch cycle.
TOLBAND
0
0–9999999
Tolerance band. For setpoints with TRIP set to HIGHER or LOWER, specifies a
tolerance band around the target weight. If the captured weight is not within the
specified tolerance band, the preact learn function is not applied and the batch is
paused (based on the value of the TOLCNT parameter, below) until restarted or
reset.
In a batch sequence with TRIP=HIGHER, the associated digital output is active until
the setpoint value is reached or exceeded; with TRIP=LOWER, the output is active
until the weight goes below the setpoint value.

TOLCNT
1
0–65535
Tolerance count. For setpoints with TRIP set to HIGHER or LOWER, specifies the
number of consecutive batch cycles in which the tolerance band (TOLBAND
parameter) must be exceeded before the batch process is paused. When the
specified value is met, the batch is paused and an error message is displayed. The
batch must be restarted or reset to clear the error message. The special value of zero
means that the batch is never paused for an out-of-tolerance condition.
RELNUM
1–100
For relative setpoints, specifies the number of the relative setpoint. The target weight
for this setpoint is determined as follows:
• For +REL setpoints, the value of the relative setpoint plus the value (VALUE
parameter) of the +REL setpoint
• For –REL setpoints, the value of the relative setpoint minus the value of the –REL
setpoint
• For %REL setpoints, the percentage (specified on the VALUE parameter of the
%REL setpoint) of the target value of the relative setpoint
• For RESREL setpoints, the percentage (specified on the VALUE parameter of the
RESREL setpoint) of the captured value of the relative setpoint

Serial Commands
The 920i indicator can be controlled by a personal
computer or remote keyboard connected to an
indicator serial port. Control is provided by a set of
serial commands that can simulate front panel key
press functions, display and change setup parameters,
and perform reporting functions. The serial
commands provide the capability to print
conÞguration data or to save that data to an attached
personal computer. This section describes the serial
command set and procedures for saving and
transferring data using the serial ports.

The serial command set can be divided into Þve
groups: key press commands, reporting commands,
the RESETCONFIGURATION special function
command, parameter setting commands, and transmit
weight data commands.
When the indicator processes a serial command, it
responds with the message OK . The OK response
veriÞes that the command was received and has been
executed. If the command is unrecognized or cannot
be executed, the indicator responds with ??.
The following sections list the commands and

parameter (Tables 9-3 through 9-11).
Current conÞguration parameter settings can be
displayed in either setup mode or normal mode using
the following syntax: command<ENTER>
Most parameter values can be changed in setup mode
only; setpoint parameters listed in Table 9-6 on
page 76 can be changed when in normal weighing
mode.
Use the following command syntax when changing
parameter values: command=value<ENTER>, where value
is either a number or a parameter value. Use no spaces
before or after the equal (=) sign. If you type an
incorrect command, the display reads ??.

9.1.7
Database Commands
The commands listed in Table 9-12 can be used to
create and maintain databases in the 920i. Except for
the D B . D E L A L L command, all of the database
commands require an extension to identify the number
of the database within the memory card and the slot
number of the memory card.
Command
Description
DB.ALIAS.n#x
Get or set database name
DB.CLEAR.n#x
Clear database contents
DB.DATA.n#x
Get or set database contents
DB.SCHEMA.n#x Get or set database structure
DB.DELALL
Delete all databases and database
contents
n represents the database number within the memory card;
x is the slot number of the memory card.
Each command must be terminated with a carriage return
character (<CR>, ASCII 13).
Table 9-12. Database Commands
Serial Commands
79
DB.ALIAS
The DB.ALIAS command is used to get or set the alias
used by iRite programs to reference the speciÞed
database. Each database alias must be unique among
all databases and adhere to the following rules: 8
character maximum; must begin with an alpha
character or an underscore; can only contain AÐZ, aÐz,
0Ð9, or an underscore (_).
Example. The following command assigns an alias of
TRUCKS_2 to the Þrst database on the memory card
installed in slot 2:
DB.ALIAS.1#2=TRUCKS_2<CR>
Sending the DB.ALIAS command alone, without
assigned data, returns the current database alias.
DB.CLEAR
To clear the contents of a database, send the following
command:
DB.CLEAR.n#x<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
The 920i responds with OK<CR> if the command is
successful, ??<CR> if unsuccessful.
DB.DATA
The DB.DATA command can be used to send data to or
retrieve data from the 920i.
Data can be sent to the indicator using the following
command:
DB.DATA.n#x = data{ | }<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
data represents a single cell of a row of data
{ | } is a pipe character (ASCII 124), used to
delimit cell data. If the data being sent is not the
last cell of the row, append the pipe character to
the data to indicate that more data is coming for
that particular row. If the data being sent is the last
cell of the row, do not append the pipe character.
If the command is accepted, the 920i responds with
OK<CR>; if not, it responds with ??<CR>.
Example. The following commands place the data
shown in Table 9-13 into the Þrst database in the
onboard memory:
DB.DATA.1#0=this|<CR>
DB.DATA.1#0=is|<CR>
DB.DATA.1#0=a|<CR>
DB.DATA.1#0=test<CR>

Table 9-13. Sample Database Contents
Sending the DB.DATA command alone, without
assigned data, returns the database contents:
DB.DATA.n#x<CR>
The 920i responds with the entire contents of the
database. Returned data is cell-delimited with the pipe
character (ASCII 124) and row-delimited with
carriage returns (ASCII 13).
For example, the following command could be used to
return the contents of database 1 in the onboard
memory:
DB.DATA.1#0<CR>
If the database contents are the records shown in
Table 9-13, the indicator responds with the following
data, using pipe characters and carriage returns to
delimit the database cells and rows, respectively:
t his| is| a | t e st < CR > a a a | bbb| c c c | ddd< CR >
NOTE: There is no end of database notification at the
end of the DB.DATA command transmission. Use a
receive time-out to determine command completion. This
time-out should vary based on baud rate.
You should determine the number of records currently
in the database both prior to and after sending the
DB.DATA command to verify that the correct number of
records are received. The number of records can be
determined with the DB.SCHEMA command.
DB.SCHEMA
The DB.SCHEMA command is used to get or set the
structure of a database.
DB.SCHEMA.n#x<CR>
The 920i responds to the command above by returning
the following:
<Max Records>,<Current Record Count>,
<Column Name>,<Data Type>,<Data Size>,...<CR>
The <Column Name>, <Data Type>, and <Data Size>
elements repeat for each column in the database.
The <Column Name> follows the rules for alias
names: 8 character maximum; must begin with an
alpha character or an underscore; can only contain
AÐZ, aÐz, 0Ð9, or an underscore (_).
The <Data Type> is represented by a numeric Þeld:
Value

The <Data Size> value must match the data type. A

Widget Programming
9.2.1
The type and location of elements shown on the 920i
display are easily speciÞed using the drag and drop
features of the iRev utility. However, display widgets
can also be programmed using serial commands while
the 920i is in setup mode, or through iRite
programming. Up to ten different screens can be
conÞgured.
Serial command widget programming is
accomplished in setup mode, using the WDGT serial
command. The Þrst parameter speciÞed is the widget
type, listed in Table 9-16. The following sections
describe each of the widget types and the parameters
and values speciÞc to that type.
In setup mode, the WDGT.CLR serial command can
be used to clear all speciÞed widgets from the display.

Scale Widgets
Scale widgets are used to present basic scale data
from one or more conÞgured scales. For multiple
scale applications, up to four scale widgets can be
conÞgured to be shown on the display at any one time.
Fewer displayed widgets allow each widget to be
larger. Scale data from additional conÞgured scales
can be shown by scrolling up or down through all
conÞgured scales, including a total scale widget, if
conÞgured.

widget types to be directly controlled by an iRite
program rather than by indicator data. The user
program must provide the code necessary for widget
manipulation.

9.2.3
Bargraph Widgets
Bargraph widgets allow display of vertical or
horizontal graphs, either a normal bargraph style or a
needle gauge, with or without graduations. The graph
can be used to represent scale weight or progress
toward a setpoint target value.

screen_number = 1–10
Example:
WDGT#2=3,30,30,30,100,2,1,1,2,,Graph1,1,1,1,1,2<CR>
creates a visible, 30 x 100 pixel bargraph widget for
screen 2, named Graph1, with a single border, with
the upper left-hand corner of the bargraph at pixel
location 30,30 (near upper left corner of display). The
bargraph is of the basic style (1), with graduations
turned on (1) and is oriented vertically (2). Bargraph
source is the gross weight from scale channel 1.

10.1 Troubleshooting
Table 10-1 lists general troubleshooting tips for various hardware and software error conditions. See the
following pages for additional information about speciÞc diagnostic tools.
The distributor site for the 920i at www.rlws.com includes a section of Frequently Asked Questions. RLWS will
post answers to questions presented to the technical support group. Check the site often for new postings.
Symptom
Cause/Remedy
Indicator does not power up
Possible blown fuse or bad power supply. Check fuses (see Section 2.8 on
page 12) and replace if necessary. Fuse specifications are listed on page 107; fuse
replacement part numbers are listed in Table 2-7 on page page 14.
If fuses are good, check all voltages on CPU board. Power supply should output
both +6V and –6V levels to the CPU board (see Figure 2-4 on page 8). If power
supply appears bad, check the small glass fuse (2.5A, 5x20mm) on the power
supply board.
Front panel power indicator blinking (
)
"Blue screen"
Power supply overloaded. Check for shorts in A/D card regulators or in the
DC-to-DC converter of any installed analog output or pulse input cards.
Check LCD contrast pot (under interface board access cover; see Figure 2-3 on
page 8). Possible corrupt core software; reset or reload software.
Hangs in "888" display
Corrupt core software. Reset or reload software.
Tare and truck data pointers are corrupt,
Tare storage is corrupt error messages at
startup
Possible dead battery. Perform configuration reset then check for low battery
warning on display. If battery is low, replace battery, perform another configuration
reset, then reload files.

Overrange or underrange scale condition. Check scale. For out-of -range
conditions in total scale display, check all scale inputs for positive weight values.
Display reads 0.000000
Scale not updating. Check for bad option card hanging the bus.
Cannot enter setup mode
Possible bad switch. Test switch; replace interface board if necessary.
Serial port not responding
Possible configuration error. For command input, ensure port INPUT parameter is
set to CMD.
A/D scale out of range
Check source scale for proper mechanical operation. Check load cell and cable
connection. Possible bad load cell: check indicator operation with load cell
simulator.
Locked — Scale in use
Scale is assigned as an input to a total scale or is the source for a serial scale,
analog output, or setpoint. If not correct, deconfigure this scale assignment and
reconfigure as required.
Serial scale out of range
Check source scale for proper mechanical operation. Check cable connection.
Possible format mismatch between serial scale and 920i: Check SFMT
specification under SERIAL menu.
Option card failure
Possible defective card or slot. Disconnect power, install card in different slot, then
apply power again.
Option card hardware diagnostic error
Required option card not found. See Section 10.1.1 on page 88.
Expansion board does not power up
Check expansion board power supply.
Table 10-1. Basic Troubleshooting
NOTE: Always save copies of the indicator configuration, calibration, iRev and iRite files on a local PC so that these are
available when a software reload or upgrade is required.
Appendix

10.1.1
Option Card Diagnostic Errors
Option cards are detected by the 920i at power-up. If
the current indicator conÞguration requires an option
card but that card is not detected at power-up, an error
similar to the following is displayed:
HARDWARE CRITICAL TO PROPER OPERATION
WITH CURRENT CONFIGURATION
CANNOT BE FOUND
A/D SLOT 4 CHANNEL 1
INSTALL HARDWARE OR RECONFIGURE
To recover from this error you can do the following:
¥ If the option is required, ensure that the card is
properly seated in its slot and cycle the power. If
the card is still not recognized, replace the card
or try installing the card in a different slot.
¥ Enter setup mode and reconÞgure to eliminate
the requirement for the option.
¥ Go to the VERSION menu and use the Reset
Config softkey (or RESETCONFIGURATION
command) to perform a conÞguration reset.
ConÞguration reset returns all conÞguration
values to their factory defaults.
See Section 10.1.2 below, for information about using
the HARDWARE serial command to verify that
installed cards are recognized.
10.1.2
Using the HARDWARE Command
The HARDWARE serial command can be issued to
verify that all installed cards are recognized by the
system. The HARDWARE command returns a string
of card type codes, representing cards installed in slots
1Ð14:
HARDWARE=3,3,2,4,5,0,0,0,0,0,0,0,0,0
Table 10-2 lists the card codes returned by the
HARDWARE command.

920i Installation Manual
If an installed card is not recognized (HARDWARE
command returns a code of 0 for that slot), ensure that
the card is seated properly. Reinstall the card, if
necessary, then cycle the indicator power to read the
conÞguration again. If the card is still not recognized,
try installing it in another slot.
NOTE: The internal Ethernet card does not return a card
type code. Any slot containing an Ethernet card will show
a value of 0 on the HARDWARE command.
10.1.3
User Program Diagnostic Errors
Faulty user programs can cause critical errors that are
detected by the 920i at power-up. The following error
message is caused by a user program attempting to
divide by zero:
A CRITICAL USER PROGRAM ERROR
HAS BEEN DETECTED
DIVIDE BY ZERO
SYSTEM RESET IS REQUIRED
To recover from this error you can do the following:
¥ Cycle the indicator power to reset the user
program.
¥ Correct the iRite program to eliminate the divide
by zero operation. Recompile the program, then
download the corrected program to the indicator.
If technical assistance is required, contact RLWS
technical support.
Diagnostic Boot Procedure
If a user program causes an error in the start-up
handler, the only way to Þx the error is to perform the
following diagnostic boot procedure.
1. Disconnect power to the 920i.
2. Connect the serial port of a PC with iRev
installed to port 2 of the 920i . Connection
must be made at 38400 bps.
3. Open the indicator enclosure and place a
jumper across the SW1 boot mode pins (see
Figure 2-4 on page 8).
4. Power up the 920i. The indicator will stall at
the diagnostic monitor.
5. Start iRev and enter monitor mode, then type
BOOT.
6. Use the indicator setup switch to enter setup
mode.
7. Remove the jumper from SW1.
8. From monitor mode, enter the
RESETCONFIGURATION command.
Determine the cause of the startup handler error, make
program corrections, then reload the corrected user
program and test.
10.1.4
Using the XE Serial Command
The XE serial command can be used to remotely query the 920i for the error conditions shown on the front panel.
The XE command returns a decimal number representing any existing error conditions. For multi-scale
applications, the value returned by the XE command represents all error conditions, if any, present on all
conÞgured scales.
If more than one error condition exists, the number returned is the sum of the values representing the error
conditions (see Table 10-3 on page 89). For example, if both a tare error (TAREERR, 65536) and a truck
database checksum error (ETRUCKERR, 8192) have occurred, the XE command returns the value 73728,
representing the sum of those two error conditions.

10.3 PS/2 Keyboard Interface
Serial port 2 on the 920i CPU board provides a
PS/2-type keyboard interface for use with a remote
keyboard. To use the keyboard interface, set the
INPUT parameter for Port 2 (under the SERIAL
menu) to KEYBD.
Table 10-5 summarizes the 920i -speciÞc functions
provided by the keyboard interface; most other
alphanumeric and navigational keys provide functions
equivalent to those typical for PC operation.
NOTE: The keyboard interface is not hot-pluggable.
Disconnect power to the 920i before plugging the
keyboard cable into the Port 2 connector.

10.4 Serial Scale Interface
Serial ports 3 through 32 can be conÞgured for serial
scale input. The serial scale function allows other
scale indicators to send gross, net, or tare weight data
to the 920i. Once a serial port has been conÞgured to
accept scale data, the data format can be customized
to match the data stream sent by that indicator.
To conÞgure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT
parameter for the selected port to SCALE.
2. Return to the SCALES menu. Under
CONFIG, drop down and select the serial
port. If the serial scale is not shown, press the
Change Type softkey to select available serial
scales, then use the navigational keys to select
the serial scale. Press Add to move the scale
to the righthand column, the press Done.
Figure 10-1. iRev Stream Formatting Display
10.5 Custom Stream Formatting
Each port can be independently conÞgured to stream a
default frame format or can be customized to stream a
user-deÞned format. Custom formatting is very
similar to the standard print formatting described in
Section 6.0.
Table 10-6 on page 92 lists the format identiÞers used
to conÞgure a custom stream format. See Section 10.6
on page 94 for examples of custom stream formats.

Scale weight
Weight for the source scale. wspec is defined as follows:
wspec Indicates whether the weight is the current displayed weight
(W, w), gross (G, g), net (N, n), or tare (T, t) weight. Upper-case
letters specify right-justified weights; lower-case are left-justified.
Optional /P, /S, or /T suffixes can be added before the ending
delimiter (>) to specify weight display in primary (/P), secondary
(/S), or tertiary (/T) units.
[–] Enter a minus sign (–) to include sign for negative values.
[0] Enter a zero (0) to display leading zeroes.
digit[[.][.]digit]
The first digit indicates the field width in characters. Decimal point
only indicates floating decimal; decimal point with following digit
indicates fixed decimal with n digits to the right of the decimal.
Two consecutive decimals send the decimal point even if it falls at
the end of the transmitted weight field.

<wwwwww>
The <W06> and <T06> indicate six digits of indicated weight and tare weight with leading zeroes. Valid
characters are W, w, G, g, T, t, N, or n (lower case indicates left justified). W indicates current weight,
G–gross weight, N–net weight, T–tare weight. /P, /S, and /T can be used to specify primary, secondary,
or tertiary units.
Minus (–) indicates sign inclusion; (0) indicates leading zeros. First digit indicates field width in
characters; a decimal point (.) indicates floating decimal point. A decimal with subsequent digit indicates
fixed decimal with n digits to the right of the decimal. Two consecutive decimals (for example, <W06..>)
send the decimal point even if it falls at the end of the transmitted weight field.
<tttttt>

10.7 Data Formats
Continuous Output Serial Data Format
If continuous transmission is conÞgured for a serial
port (STREAM parameter set to LFT or INDUST on
the SERIAL menu), the 920i sends data using the
Consolidated Controls serial data format shown in
Figure 10-2:
<STX> <POL> <wwwwwww> <UNIT> <G/N> <S> <TERM>
ASCII 02
decimal
G = Gross
N = Net
Polarity:
<space> = Positive
<–> = Negative
Weight: 7 digits, right-justified, dummy
zeroes, decimal point with no leading
zeroes except for leading zero immediately
preceding the decimal point. Leading
zeroes transmitted as spaces.
L = pounds
K = kilograms
T = tons
G = grains
<space> = grams
O = ounces
<CR> <LF>
or <CR>
If the initiating device address matches the port address
of an 920i on the RS-485 network, that indicator
responds. For example, with demand outputs, or in
response to a KPRINT command, the responding
indicator uses the format shown in Figure 10-4:
<STX> <ADDRESS> <DEMAND DATA> <ETX> <CR>

NOTE: If the scale capacity is exceeded, the weight data field
is replaced with >>>>>>> characters. If the display capability
of the indicator is exceeded, the weight field is replaced with
VERFLOW ("overflow"). Both errors set the <S> status data
field to "I".
Demand Output Serial Data Format
When demand mode is conÞgured for the serial port
(STREAM parameter set to OFF), the 920i uses a data
string formatted for a basic ticket printout. The
particular ticket format printed depends on the
indicator conÞguration.
You can customize the ticket to work with a wide
variety of printers, scoreboard displays, and other
remote equipment. See Section 6.0 on page 47 for
more information on custom print formats.
ASCII terminal to an indicator at address 65 (decimal)
on the RS-485 network, use the format shown in
Figure 10-3.
¥ The keyboard equivalent for the start-of-text
(STX) character is CONTROL-B.
¥ The indicator address (65) is represented by an
upper case ÒAÓ.
¥ The carriage return (CR) character is generated
by pressing the ENTER key.
Therefore, to send the KPRINT command to the
indicator at address 65, enter the following at the
terminal: CONTROL-B, A, K, P, R, I, N, T, ENTER.
The indicator responds with the format shown in
Figure 10-4:

communications is supported on the ÒAÓ ports of any
installed serial expansion cards.
The 920i has a built-in RS-485 software protocol
which is enabled when you assign a non-zero address
to the indicator. Valid RS-485 addresses must be in the
range 1Ð255; the address is speciÞed on the
ADDRESS parameter on the SERIAL menu.
All remote commands are initiated using the data
format shown in Figure 10-3:
If continuous transmission is conÞgured for the serial

10.9 Digital Filtering
Standard digital Þltering uses mathematical averaging
to eliminate the variant digital readings that the A/D
converter sends periodically because of external
vibration. Digital Þltering does not affect the indicator
measurement rate, but does affect the settling time.
The selections from 1 to 256 reßect the number of
readings averaged per update period. When a reading
is encountered that is outside a predetermined band,
the averaging is overridden, and the display jumps
directly to the new value.
DIGFLx Parameters
The Þrst three digital Þltering parameters, DIGFLT1,
DIGFLT2, and DIGFLT3, are conÞgurable Þlter
stages that control the effect of a single A/D reading
on the displayed weight. The value assigned to each
parameter sets the number of readings received from
the preceding Þlter stage before averaging.
The overall Þltering effect can be expressed by adding
the values assigned to the Þlter stages:
DIGFLT1 + DIGFLT2 + DIGFLT3
For example, if the Þlters are conÞgured as
DIGFLT1=16, DIGFLT2=4, and DIGFLT3=4, the
overall Þltering effect is 24 (16 + 4 + 4). With this
conÞguration, each A/D reading has a 1-in-24 effect
on the displayed weight value. Setting the Þlters to 1
effectively disables digital Þltering.
RATTLETRAP® Filtering
RATTLETRAP digital Þltering (RATTRAP parameter
set ON) uses a vibration-dampening algorithm to
provide a combination of the best features of analog
and digital Þltering. The RATTLETRAP algorithm
evaluates the frequency of a repeating vibration then
derives a composite displayed weight equal to the
actual weight on the scale less the vibration-induced
ßaws. It is particularly effective for eliminating
vibration effects or mechanical interference from
nearby machinery. Using RATTLETRAP Þltering can
eliminate much more mechanical vibration than
standard digital Þltering, but will usually increase
settling time over standard digital Þltering.
DFSENS and DFTHRH Parameters
The digital Þlter can be used by itself to eliminate
vibration effects, but heavy Þltering also increases
settling time. The DFSENS (digital Þlter sensitivity)
and DFTHRH (digital Þlter threshold) parameters can
be used to temporarily override Þlter averaging and
improve settling time:
100
920i Installation Manual
¥
¥
DFSENS speciÞes the number of consecutive
scale readings that must fall outside the Þlter
threshold (DFTHRH) before digital Þltering
is suspended.
DFTHRH sets a threshold value, in display
divisions. When a speciÞed number of
consecutive scale readings (DFSENS) fall
outside of this threshold, digital Þltering is
suspended. Set DFTHRH to NONE to turn off
the Þlter override.
Setting the Digital Filter Parameters
Fine-tuning the digital Þlter parameters greatly
improves indicator performance in heavy-vibration
environments. Use the following procedure to
determine vibration effects on the scale and optimize
the digital Þltering conÞguration.
1. In setup mode, set the digital Þlter parameters
(DIGFLT1ÐDIGFLT3) to 1. Set DFTHRH to
NONE. Return indicator to normal mode.
2. Remove all weight from the scale, then watch
the indicator display to determine the
magnitude of vibration effects on the scale.
Record the weight below which all but a few
readings fall. This value is used to calculate
the DFTHRH parameter value in Step 4.
For example, if a heavy-capacity scale (10000
x 5 lb) produces vibration-related readings of
up to 50 lb, with occasional spikes to 75 lb,
record 50 lb as the threshold weight value.
3. Place the indicator in setup mode and set the
DIGFLTx parameters to eliminate the
vibration effects on the scale. (Leave
DFTHRH set to NONE.) Find the lowest
effective value for the DIGFLTx parameters.
4. Calculate the DFTHRH parameter value by
converting the weight value recorded in Step
2 to display divisions:
threshold_weight_value / display_divisions
In the example in Step 2, with a threshold
weight value of 50 lb and a display divisions
value of 5 lb: 50 / 5 = 10. DFTHRH should be
set to 10D for this example.
5. Finally, set the DFSENS parameter high
enough to ignore transient peaks. Longer
transients (typically caused by lower vibration
frequencies) will cause more consecutive
out-of-band readings, so DFSENS should be
set higher to counter low frequency transients.
ReconÞgure as necessary to Þnd the lowest
effective value for the DFSENS parameter.
10.10 Conversion Factors for Secondary Units
The 920i has the capability to mathematically convert a weight into many different types of units and instantly
display those results with a press of the UNITS key.
Secondary and tertiary units can be speciÞed on the FORMAT menu using the SECNDR and TERTIA
parameters, or by using serial commands.
¥ To conÞgure secondary or tertiary units using the front panel menus, use the Table 10-12 to Þnd the
conversion multiplier for the MULT parameter. For example, if the primary unit is pounds and the
secondary unit is short tons, set the MULT parameter to 0.000500.
¥ To conÞgure secondary or tertiary units using serial commands, use the Table 10-12 to Þnd the
conversion multiplier for the SC.SEC.MULT or SC.TER.MULT command. For example, if the primary
unit is pounds and the secondary unit is short tons, send the serial command SC.SEC.MULT=
0.0005<CR> to set the multiplier for the secondary units.
NOTE: Ensure that the secondary decimal point position is set appropriately for the scale capacity in the
secondary units. If the converted value requires more digits than are available, the indicator displays an overßow
message (OVERFL).
For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is
set to 8888.888, the indicator will overßow if 5 tons or more are applied to the scale. With 5 tons applied, and a
conversion factor of 2000, the secondary units display needs Þve digits to the left of the decimal point to display
the 10000 lb secondary units value.
