Overview
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
Note 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 North American 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.
Option Cards
The CPU board provides two slots for installing A/D or other option cards. Additional option cards can be added

Enclosures
The 920i is available in four enclosures: universal (tiltFigure 1-1. 920i Front Panel
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.

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 equal to 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.
Toggle Units
Press the Units key to switch between primary, secondary, and tertiary units.
Zero Scale
1. In gross mode, remove all weight from the scale and wait for the standstill annunciator (
).
2. Press the Zero key. The center of zero ( 0 ) annunciator lights to indicate the scale is zeroed.
Acquire Tare
1. Place a container on the scale and wait for the standstill annunciator (
).
2. Press the Tare key to acquire the tare weight of the container. The net weight the word Net displays.
Remove Stored Tare Value
1. Remove all weight from the scale and wait for the standstill annunciator (
).
2. Press the Tare key (or, in OIML mode, the Zero key). Display shifts to gross weight and shows the word
Gross.
Print Ticket
1. Wait for the standstill annunciator (
).
2. Press the Print key to send data to the serial port. To print tickets using auxiliary formats, press the number
key for the format, then press Print. For example, to print using AUXFMT2, press 2, then Print.
Accumulator Functions
The accumulator must be enabled before use in either weigh mode or setpoint operations. Once enabled, weight
(net weight if a tare is in the system) is accumulated whenever a print operation is performed using the Print key,
digital input, or serial command. The scale must return to zero (net zero if a tare is in the system) before the next
accumulation.
The Display Accum softkey can be configured to display the current accumulator value. Printing while the
accumulator is displayed, or when the setpoint PSHACCUM function is active, uses the ACCFMT print format
(see Section 7.0 on page 69).
Press the Clear key twice to clear the accumulator.

The universal model of the 920i provides six cord grips for cabling into the indicator: one for the power cord, five
to accommodate cabling for option cards. Install plugs in all unused cord grips to prevent moisture from entering
the enclosure.
2.3.1 Installing Sealed USB Connectors
For washdown environments, optional sealed USB connectors are available for use with a specialized backplate.
To install the sealed USB connectors,
1. Align the watertight USB connectors with the notches in the backplate. For optimal cable routing, it
recommended for the Type-A connector to be on the left side and the Type-B connector to be on the right
side, as shown in Figure 2-1.
The hole in the backplate is keyed. Ensure the key on the watertight USB connector is inserted in the notch in
Note the backplate.
2. Fasten the watertight connectors so they are flush
with the backplate.
3. Connect the interface cables to the headers on the
USB card.
4. Install the backplate (see Section 2.6 on page 16).

Battery Replacement
The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM
when the indicator is not connected to AC power.
Data protected by the CPU board battery includes time and date, truck and tare memory, onboard database
information, and setpoint configuration.
Use iRev 4 to store a copy of the indicator configuration on a PC before attempting battery replacement. If any data
is lost, the indicator configuration can be restored from the PC.
Memory option card data is also protected by a lithium battery. All database information stored on a memory
Note 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.
Removal (Applies to Rev H Board)
Place the tip of a finger in the notched area near the battery retaining spring
and slide the battery out of position on the CPU board. See Figure 2-10.
Replacement
Before replacing the battery, place the indicator in setup mode, then press
SAVE/EXIT to save battery-backed memory (NVRAM) to flash. This
operation saves the latest configuration information, including setpoint
values, stored strings and data, and the onboard database, to flash memory.
Return to weigh mode, power off the indicator, and replace the battery. Use
care not to bend the battery retaining spring.
Figure 2-10. Battery Removal
When power is restored, a message is shown stating that battery-backed
memory is corrupt. Press Enter to restore the values saved in flash memory.
See Figure 2-5 on page 12 for CPU board battery location and orientation (positive side up).
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
CAUTION recommended by the manufacturer. Dispose of unused batteries according to the manufacturer’s
instructions.

The 920i USB indicator can be configured by using the front panel keys to navigate through a series of
configuration menus or by sending commands or configuration data to an indicator serial port. If there is no serial
port on port 2, refer to Section 6.0 on page 64. Configuration using the menus is described in Section 3.1.3.
Configuration using the serial port can be accomplished using either the serial command set described in
Section 10.0 or the iRev 4 configuration utility.
Some configuration parameters, such as those used to configure the 920i USB display and widgets, cannot be
Note accessed through the configuration menus. iRev 4 provides the most complete and efficient configuration
interface for the 920i USB.
3.1.1
iRev Configuration
The iRev 4 configuration utility provides the preferred method for configuring the 920i indicator. iRev 4 runs on a
personal computer to set configuration parameters for the indicator. When iRev 4 configuration is complete,
configuration data is downloaded to the indicator.
iRev 4 supports both uploading and downloading of indicator configuration data. This capability allows
configuration data to be retrieved from one indicator, edited, then downloaded to another indicator with an
identical hardware configuration.
Note If using iQUBE 1, use iRev 3. If using iQUBE2 or no iQUBE, use iRev 4.
iRev 3 cannot be used to edit a file created in iRev 4. iRev must be newer or the same version as the file
Important being opened.
Figure 3-1. iRev Hardware Configuration Display
To use iRev 4, do the following:
1. Install iRev 4 on an IBM-compatible personal computer. See Section 5.0 on page 59 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.
22
920i Programmable HMI Indicator/Controller
Note If there is no serial port on port 2, refer to Section 6.0 on page 64.
3. Power up the PC and the indicator. Use the setup switch to place the indicator in setup mode.
4. Start the iRev 4 program.
iRev 4 provides online help for each of its configuration displays. Parameter descriptions provided in this manual for
front panel configuration can also be used when configuring the indicator using iRev 4: The interface is different, but
the parameters set are the same.
See Section 5.0 on page 59 for more information about using iRev 4 to configure the 920i.
3.1.2
Serial Command Configuration
The serial command set can be used to configure the 920i indicator using either a personal computer, terminal, or
remote keyboard. Like iRev 4, serial command configuration sends commands to the indicator serial port; unlike
iRev 4, 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 configure the indicator,
or to dump lists of parameter settings. See Section 10.0 on page 98 for more information about using the serial
command set.
3.1.3
Front Panel Configuration
Use the CONFIG submenu under the SCALES menu to configure A/D scales. For example, in an indicator with a
single-channel A/D card installed in Slot 1, the Scale Configuration 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/D’s column. If no other A/D’s 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 Configuration
display.
See Section 11.4 on page 124 for information about configuring serial scales.
Figure 3-2. Scale Configuration Display
3.1.4
Multi-Range and Multi-Interval Scales
The 920i supports multi-range and multi-interval scales of either two or three ranges or intervals.
Multi-range scales provide two or three ranges, each extending from zero to the maximum capacity specified for
the range, that can specify different scale intervals (graduations). The scale interval changes as the applied weight
increases but does not reset to lower range intervals until the scale returns to zero.
Multi-interval scales divide the scale into two or three partial weighing ranges, each with different scale intervals.
The scale interval changes with both increasing and decreasing loads applied.
To configure a multi-range or multi-interval scale, use the SPLIT parameter to select 2RNG or 3RNG (for multirange scales), or 2INTVL or 3INTVL (for multi-interval scales). Selecting a SPLIT value other than OFF allows
specification of decimal point, display divisions, and maximum capacity for each range or interval.
Configuration
23
3.1.5
Total Scale Configuration
The output of two or more A/D scales or iQUBE2 systems can be configured to function as a total scale. Once
configured and calibrated, the total scale can be used as a source for other system functions, including streaming,
setpoints, print formatting, and analog output.
To set up a total scale from the indicator front panel, use the scale configuration display (see Figure 3-2) to select
the A/D scales or iQUBE2 systems to configure as a total scale. (Use the Change Type softkey to show available A/
D scales or iQUBE2 systems; use the right navigation key to select the total scale sources.) In iRev 4, assign the
total scale to an unused position then select source scales from the existing A/D scales or iQUBE2 systems.
The FORMAT configuration of the total scale (see Figure 3-5 on page 29) should match that of the source scales.
However, the value specified for the total scale GRADS parameter should be specified as the sum of the GRADS
values for the source scales. For example: if SCALE 1 is set to GRADS=10000, SCALE 2 to GRADS=5000,
SCALE 3 (the total scale) should be set to 15000 grads.
The total scale will show an over-range indication if the maximum capacity of any source scale is exceeded, and
show dashes if any source scale reads a negative value. The zero operation applies to both Source and Total Scales
but a zero operation on all scales will only work if all scales can be zeroed. If any scales are in motion or out of zero
range, the zero operation will fail. Source scales are always left in gross mode. The tare operation only applied to
the total scale, which will display gross or net weights.
3.2
Menu Structures and Parameter Descriptions
The 920i indicator can be configured using a series of menus accessed through the indicator front panel when the
indicator is in setup mode. Figure 3-1 summarizes the functions of each of the main menus.

Rate of Change (ROC) Units Parameters
For applications using the ROC function, the primary scale should be configured with a finer resolution than the rate of change
(ROC) units to prevent a stepwise appearance in the ROC display. The ROC display step size (weight increment between
displayed values) can be roughly calculated as follows:
(updates_per_ROC_UNIT) * (PRIMARY_resolution / ROC_resolution)
For example, with INTERVL=30; REFRESH =0.1; UNITS=MIN; PRIMARY resolution at 0.1 LB and ROC resolution at 1.0 (LB/
MIN):
-INTERVL * REFRESH = 30 * 0.1 = 3.0 seconds per update (ROC data is flushed every 3.0 seconds)
-With UNITS = MIN, there are 20 ROC data updates per ROC time unit: 60 seconds / 3.0 seconds per update
-The resolution ratio of PRIMARY to ROC units is 0.1 (0.1 / 1.0)
-This configuration provides a step size in the ROC display of 2 LB (2 LB increments between displayed values):
20 * 0.1 = 2
Note that setting both PRIMARY and ROC display resolutions to 1 LB would have resulted in a step size of 20 LB.

OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is at no
load. NONE allows tares to be cleared at any weight value.
NTEP and OIML modes allow a new tare to be acquired even if a tare is already present. In
CANADA mode, the previous tare must be cleared before a new tare can be acquired.
NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net mode
as long as the current weight is within the specified ZRANGE. In OIML mode, the scale must
be in gross mode before it can be zeroed; pressing the ZERO key in net mode clears the
tare.
INDUST provides a set of subparameters to allow customization of tare, clear, and print
functions in non-legal-for-trade scale installations. See Level 4 parameter descriptions in
Table 3-9 on page 48.

Fieldbus (FLDBUS) Menu
The FLDBUS menu is shown only if a DeviceNet, Profibus, EtherNet/IP, or ControlNet option card is installed.
The SWAP parameter on the FLDBUS menu enables byte swapping by the iRite BusCommand handler rather than
requiring a SWP (SWAPBYTE) instruction in the PLC. Byte swapping is enabled by default for DeviceNet cards;
for all other fieldbus cards, byte swapping is disabled by default.
• BYTE swaps bytes within the word before transmission to the scanner
• WORD swaps words 1 and 2, 3 and 4, within a 4-word packet
• BOTH performs both operations, swapping bytes within a word and swapping words within the packet
• NONE disables swapping
The DATASIZE parameter sets the size of the BusCommand handler data transfers. The default value (8 bytes)
matches the default data size specified in the EDS and GSD files, and used by the standard discrete transfer
commands. DATASIZE can be set to any value from 2–128 bytes (1–64 words), but the value specified must match
the data size set for the PLC Scanner I/O data size.

Gravity Compensation
Gravity compensation for latitude and elevation is available for the 920i. To calibrate with gravity compensation,
the LOCALE parameter under the FEATURE menu must be set ON, and the LATUDE (latitude) and ELEVAT
(elevation, in meters) parameters set before calibrating the indicator (see Figure 3-13 on page 43).
If the indicator is later installed at a different location, gravity compensation can be applied to a pre-calibrated
indicator by adjusting the LATUDE and ELEVAT parameters.
4.2
Front Panel Calibration
The CALIBR submenu (under the SCALES menu, see Figure 4-2) is used to calibrate the 920i. The zero, span, and
linear calibration point displays provide a set of softkeys used specifically for calibration procedures:

Figure 4-2. WZERO Calibration Display
To calibrate the indicator using the front panel:
1. Place the indicator in setup mode (display reads Scale Configuration) and remove all weight from the scale
platform. If the test weights require hooks or chains, place the hooks or chains on the scale for zero
calibration.
2. With the SCALES menu highlighted, press the down key, then select the scale to be calibrated. Press down
again (GRADS parameter highlighted), then press left to highlight the CALIBR submenu (see Figure 4-1).
Press down to go to zero calibration (WZERO). See Figure 4-2 on page 56.
3. Ensure scale is empty, then press down again to show the current WZERO value, then press the Calibrate
softkey to calibrate zero. When complete, the new A/D count for the zero calibration is displayed. Press
enter to save the zero calibration value and go to the next prompt (WVAL).
4. With WVAL displayed, press down to show the stored calibration weight value. Use the numeric keypad to
enter the actual value of the calibration test weights, then press enter to save the value and go to span
calibration (WSPAN).
5. Place test weights on scale. Press down again to show the current WSPAN value, then press the Calibrate
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 five additional points between the zero and span calibrations.
Linearization is optional: if not performing linearization, skip the WLIN parameter; if linearization values
have previously been entered, these values are reset to zero during calibration. WZERO and WSPAN must
be calibrated before adding linearization points; WLIN values must be less than the WSPAN value and
must not duplicate WZERO or WSPAN.
To perform linearization, follow the procedure below:
With WLIN displayed, Press down to go to the first linearization point (POINT 1). Press down again to show
the weight value prompt (WGT 1), then down once more to show the weight value. Place test weights on the
scale, then use the numeric keypad to enter the actual test weight value. Press enter to save the value and
move to the calibration (CAL 1) prompt. Press down to show the current calibration value, then press the
Calibrate softkey to calibrate the linearization point. When complete, the A/D count for the linear
calibration is displayed. Press enter again to save the calibration value and go to the next prompt (POINT 2).
Repeat for up to five linearization points. To exit the linearization parameters, press the up key to return to
WLIN.
7. The optional rezero function is used to remove a calibration offset when hooks or chains are used to hang
the test weights.
Note The rezero function cannot be used with five-point linear calibration.
56
920i Programmable HMI Indicator/Controller
• If no other apparatus was used to hang the test weights during calibration, remove the test weights and
press up to return to the CALIBR submenu.
• If hooks or chains were used during calibration, remove these and the test weights from the scale. With
all weight removed, go to the REZERO parameter, then press down to show the current zero value. Press
the Calibrate softkey to adjust the zero and span calibration values. Press enter or up to return to the
CALIBR submenu.
8. Press up to return to the SCALES menu, or press the Save and Exit softkey to exit setup mode.
4.3
Serial Command Calibration
To calibrate the indicator using serial commands, the serial port must be connected to a terminal or personal
computer. See Section 2.3.4 on page 10 for serial port pin assignments; see Section 10.0 on page 98 for more
information about using serial commands.
Once the indicator is connected to the sending device:
1. Place the indicator in setup mode (display reads CONFIG) and remove all weight from the scale platform. If
the 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 five linearization points can be calibrated between the zero and span calibration values. 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 SC.REZERO#n serial command.
7. Send the KSAVEEXIT serial command to save the calibration changes and exit setup mode.
4.4
iRev Calibration
The iRev 4 Calibration Wizard provides step-by-step scale calibration. With the 920i connected to the PC, select
the Calibration Wizard from the Tools menu on the iRev 4 Scales display, then follow the steps listed below to
calibrate the scale. See Section 5.0 on page 59 for a general overview of the iRev 4 utility.

2. Select the scale to be calibrated.
3. Enter the test weight used to calibrate the scale. If using chains or hooks to hold the weights, check the box
below the test weight value entry. This adds a rezero step to the calibration sequence.
4. Remove all weights from the scale. If chains or hooks were used, place them on the scale. Press the
Calibrate Zero button to perform the zero calibration. A message box appears when the process is complete.
5. Apply the test weights to the scale. Press the Calibrate Span button to perform the span calibration. A
message box appears when the process is complete.
6. If the option for chains or hooks was selected in step 3, the Rezero display is shown. Remove all weights
from the scale, including chains or hooks. Press the Re-Zero button to calibrate the zero offset.
7. If performing a multi-point linear calibration, up to five other calibration weight values can be entered on
the display. The weights must be in ascending order and must not include zero or the span weight. Enter the
weight values and click the Go button to calibrate each point.

Connecting to the Indicator
Connect the PC serial port to port 2 of the 920i. Return to the Hardware Configuration display, then click on the
Connect icon in the toolbar. iRev 4 attempts to establish communications to the indicator.
Once communications is established, iRev 4 queries the indicator configuration to determine whether the indicator
hardware matches the virtual hardware configured in the current iRev 4 file. If the hardware matches, the Hardware
Configuration section of iRev 4 is disabled, preventing further changes.
If the hardware does not match, there is an option of either canceling the connect operation or overwriting the iRev 4
hardware configuration with the actual indicator hardware configuration.
5.6.1 Downloading to the Indicator

Because less data is transferred using Download Current Display, it is typically faster than a full configuration
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 Download Configuration function.
A progress message is displayed during the download indicating the progress of the download and also during the
clear memory indicating its progress.
5.6.2
Uploading Configuration to iRev
The Upload Configuration function on the iRev 4 Communications menu allows the existing configuration of a
connected indicator to be saved to a file on the PC. Once saved, the configuration file provides a backup that can be
quickly restored to the indicator if needed. Or, the file can be edited within iRev 4, then downloaded back to the
indicator.
Note The indicator must be in setup mode before uploading or downloading data.
5.7
Installing Software Upgrades
This section applies only to 920i units using a serial board, not a USB board.
New releases of the 920i system software can be downloaded and installed using an Internet connection and the
Rice Lake Web Update application.
Before upgrading to a new version of 920i system software, ensure that a copy of the current indicator
Note configuration has been saved using iRev 4. Reloading the system software requires a RESETCONFIGURATION
function and resets all configuration and calibration values to their factory defaults.
Figure 5-5. Rice Lake Web Update Display
Click on the Check for Updates button in the Rice Lake Web Update application to check if a new version of the
920i software is available. To download a new software version, select the new software version and click on Get
Selection. Once the new software is downloaded to the PC, do the following:
1. Disconnect power to the 920i.
2. Connect the PC serial port 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 2-5 on
page 12).
4. Power up the 920i. The indicator will stall at the diagnostic monitor.

Using USB Devices
The 920i’s USB interface port can be used to connect devices using a type-A or type-B connector.
Version 5.00.00 Rev L boards (or higher) are required for USB functionality. See the iRite programming manual
Note for APIs which can perform USB functions. If running a user program, functions may vary.
Type B
Type A
Figure 6-1. USB connector types
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.
If using a host PC connection, this connection must terminated prior to switching devices or entering
Note configuration mode on the 920i. Otherwise, Host PC may not display when the USB softkey is pressed once
the 920i has returned to weigh mode.
Flash drives allow users to save and load configuration files (.920), save and load database files (.db), load user
programs, and update the boot monitor and core firmware. Flash drives must be formatted in the FAT-16 or FAT-32
file system, cannot exceed 4 Gig drive size, cannot exceed eight character name and three character extension.
Connecting a USB keyboard allows users to type alphanumeric characters rather than use the front panel buttons.
6.1
USB Driver Installation

Connecting a USB Device
The 920i will display a list of connected USB devices. Devices in this list can include the following:
Device
HOSTPC
PRINTER1
PRINTER2
KEYBOARD
DRIVE
Description
HOSTPC is used when connecting directly to a PC. The PC will automatically assign a virtual comm port.
Check PC settings to determine which port is assigned.
PRINTER1 is used if one printer is connected. PRINTER2 is used only if a USB hub is connected, allowing for
more than one Type-B connection. In this scenario, the lowest printer ID# will be Printer1.
KEYBOARD supports USB keyboards.
DRIVE supports USB 2.0 flash drives formatted to the FAT-32 or FAT-16 file system up to 4 Gig maximum.
Table 6-1. USB Devices
Use the following To connect a USB device,
1. Attach the USB device to the proper USB connector on the indicator. USB connections use Port 2 on the
920i.
2. Press the USB softkey.
If the USB softkey is not displayed, see Section 1.5 on page 4 and Figure 3-13 on page 43 to enable the
Note softkey.
3. Select the proper device type and press Enter.
6.3
Using USB Hubs
Hubs are necessary if multiple USB devices are desired to be simultaneously connected. To achieve best results,
use a self-powered hub and follow the below instructions when connecting devices:
1. Connect all USB devices to the hub.
2. With the 920i disconnected from power, connect the hub to the 920i.
3. Connect power to the 920i. All USB devices should be recognized on power-up.
6.4
Disconnecting a USB Device
Prior to unplugging a connected USB device,
1. Press the USB softkey.
If the USB softkey is not displayed, see Section 1.5 on page 4 and Figure 3-13 on page 43 to enable the
Note softkey.
2. Select No Device* and press Enter. This also allows a user program to switch devices via APIs.
3. The USB device is now safe to disconnect.
6.5
Loading Configuration Files and Databases
Certain files may take extended periods of time to load directly from a PC to the 920i. For fastest loading times,
using a Flash drive is recommended.
It is also recommended to create a folder matching each 920i’s unit ID number, if using multiple 920i units. When
loading configuration files, the unit will load the file contained in a folder matching its UID# (the default UID# is 1).
If no folder matching the UID is found, the unit will load the first file found.
6.5.1
Loading Configuration Files
When a file is loaded from a USB flash Drive, the calibration is always included and will overwrite existing
calibration. To eliminate this, the 920i configuration file should be downloaded to the indicator before calibration is
completed.
If loading a configuration file from a UID subdirectory, ensure the configuration file does not change the
Important unit ID. Otherwise, a .COD file in that subdirectory will not be recognized until the UID is manually
reverted to its original number.
Note File names are limited to eight characters.

Print Formatting
The 920i provides 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, ALERT,
AUXFMT1—AUXFMT20, and AUDITFMT. 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 configuration (see Table 7-3 on page 71) 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. Use the iRev 4™ configuration utility, serial commands, or the indicator front panel
(PFORMT menu) to customize the print formats.
7.1
Print Formatting Commands
Table 7-1 lists commands that can be used to format the 920i print formats. Commands included in the format
strings must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on

Customizing Print Formats
The following sections describe procedures for customizing print formats using the iRev 4 configuration utility,
serial commands, or the front panel (PFORMT menu). See Section 11.6 on page 126 for information about custom
stream formatting.
7.4.1
Using iRev
The iRev 4 configuration utility provides a ticket formatting grid with a tool bar. The grid allows the construction of
the ticket format without using the formatting commands (<NL> and <SP>) required by the front panel or serial
command methods. Using iRev 4, type text directly into the grid, then select weight value fields from the tool bar
and place them where they will appear on the printed ticket.
Figure 7-1 shows an example of the iRev 4 print formatting display.

Each print format can be edited from the front panel using a character selection like that shown in Figure 7-3. Use
the navigation keys (up, down, left, right) to move around and between the format command line and the character
selection list.
Figure 7-3. Print Formatting Character Selection Display
• To add a character: position the cursor in the format where the character is to be added. 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.
Print Formatting
73
• 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.
• To delete a character, position the cursor to the right of the character to be deleted from the format string, then
press the Clear 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 (1–255) 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.
The Print Test softkey is not available for the HDRFMTx formats. These formats can be output only when
Note inserted into one of the printable ticket formats by using the <H1> or <H2> print format commands.
7.4.3
Using Serial Commands
With a personal computer, terminal, or remote keyboard attached to one of the 920i serial ports, use the serial
command set described in Table 7-1 on page 69 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 configuration of the GFMT format, type GFMT.FMT and press Enter. The indicator
responds by sending the current configuration 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
modified print format string. For example, to add the name and address of a company to the gross format, 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. Truck IDs can be up to 16
alphanumeric characters in length.

Table 8-1. Truck Mode Features
Stored IDs – keeps a database of truck IDs and weigh-in weights in the indicator’s 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, it’s 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 – allows manual entering of 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.
Some local regulations require the tare weight to be read from the scale. If so, don’t use the keyed tares
Note feature.
Value swapping – ensures that the lowest of two weight values associated with a particular ID number is used 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.
8.1
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.
Next, go right to the SOFTKEYS submenu and configure the Weigh In, Weigh Out, and Truck Regs softkeys. These
keys are required when using the truck modes.

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 8-2).
Figure 8-2. Truck Register Display
Softkeys shown at the bottom of the Truck Regs display are described below.
Page Up
Shows previous page of the truck 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 on page 71).
If a non-zero setpoint password is configured (SPPWD parameter on the FEATURE menu), password must
Note entered before any truck register entries can be deleted.
8.3
Weigh-In Procedure
In modes 1 and 2, the indicator erases truck ID numbers and tare weights from memory after the transaction. In
modes 3–6,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:
ID 304812
GROSS 15000. LB INBOUND
01/14/2002 10:24 AM
5. Truck leaves the scale.

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 8-2 on page 76).
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.
8.5
Single-Transaction Tare Weights and IDs
One-time transactions are supported in all modes that can be configured to use stored IDs (modes 3–6). 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, press the Weigh In or Weigh Out softkey, then enter a truck ID containing a decimal point. IDs
entered with a decimal point as part of the ID are erased from the truck register when the transaction is complete.

Setpoints
The 920i indicator provides 100 configurable setpoints for control of both indicator and external equipment
functions. Setpoints can be configured to perform actions or functions based on specified parameter conditions.
Parameters associated with various setpoint kinds can, for example, be configured 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.
Note Weight-based setpoints are tripped by values specified in primary units only.
9.1
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 specified 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 defined 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, activate the BATCHNG parameter on the SETPTS menu. This parameter defines
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 defined but the BATCH parameter is off, the setpoint operates as a continuous setpoint, even during
batch sequences.
In applications that contain both batch setpoint routines and continuous setpoints, continuous setpoints
Note 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.

%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.
X
X
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.
X
X
PAUSE
Pauses the batch sequence indefinitely. A BATSTRT signal must be initiated to continue the
batch process.
X
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.
X
WAITSS
Wait for standstill. Suspends the batch sequence until the scale is at standstill.
X
COUNTER
Specifies the number of consecutive batch sequences to perform. Counter setpoints should
be placed at the beginning of a batch routine.
X
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.
X
The AUTOJOG digital output is typically used to signify that an autojog
Note 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.
X
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.
X
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.
X
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.
X
TIMER
Tracks the progress of a batch sequence based on a timer.
X
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
X
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.
The digital output assigned to the Concur Setpoint should not be used by
Note another Concur Setpoint, this may cause a conflict in setting the output state.
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.

AVG
Description
Batch
Average setpoint. Performs functions based on the calculated average weight over a
specified number of A/D samples.
X
Continuous
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.
X
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.
X
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.
X
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.
X
DINCNT
Digital input count setpoint. Counts pulses received at the specified digital input.

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, 0–9999999, 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 using a fixed value specified on the
PREVAL parameter.
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 PREVAL by the PREADJ value times the difference after each
batch.
FLOW preact provides dynamic 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
TRIP minus 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 PREVAL value.
PREADJ
0.500000
0–9999999
Preact adjustment factor. For setpoints with PREACT set to LEARN, 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
Preact stabilization time-out. For setpoints with PREACT set to LEARN, 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, 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.

WARNING by emergency stop switches and other safety devices necessary for the application.
Batching Switch
The batching switch option, PN 19369, comes as a complete unit in an FRP enclosure, with legend plate, locking
stop switch (mushroom button), and a run/start/abort 3-way switch.
Both switches are wired into the indicator’s digital I/O terminal strip as shown in Figure 9-12. Each switch uses a
separate digital input.
Once cables and switches have been connected to the indicator, use the setup switch to place the indicator in setup
mode. Use the digital I/O menu (see Section 3.2.6 on page 51) to configure digital input and output functions.
Figure 9-11. Batching Switch
94
920i Programmable HMI Indicator/Controller
When configuration is complete, exit setup mode. Initialize the batch by turning the 3-way switch to ABORT, then
unlock the STOP button (the STOP button must be in the OUT position to allow the batch process to run). The
batching switch is now ready to use.
If no digital input is assigned to BATRUN, batching proceeds as if BATRUN were always on: the batch will
WARNING start when the 3-way switch is turned to RUN, but the STOP mushroom button will not function.

Figure 9-12. Batching Switch Wiring Diagram Example
To begin a batch process, turn the 3-way switch to START momentarily. If the STOP button is pushed during the
batch process, the process halts and the button locks in the IN position.
The START switch is ignored while the STOP button is locked in the IN position. The STOP button must be turned
counterclockwise to unlock it, then released into the OUT position to enable the 3-way switch.
To restart an interrupted batch from the step where it left off, do the following:
1. Unlock STOP button (OUT position)
2. Turn 3-way switch to START
To restart an interrupted batch from the first batch step, do the following:
1. Turn 3-way switch to ABORT
2. Unlock STOP button (OUT position)
3. Turn 3-way switch to START

Batching Examples
Example 1
The following example is used to dispense 100-lb drafts, automatically refilling a hopper to 1000 lb gross weight
once the gross weight has dropped below 300 lb.
Setpoint 1 ensures that the hopper has enough material to start the batch. If the hopper weight is 100 lb or higher,
setpoint 1 is tripped.
SETPOINT=1
KIND=GROSS
VALUE=100
TRIP=HIGHER
BATCH=ON
ALARM=ON
Setpoint 2 waits for standstill, performs a tare, and puts the indicator into net mode.
SETPOINT=2
KIND=WAITSS
PSHTARE=ON
Setpoint 3 is used as a reference (relative setpoint) for setpoint 4.
SETPOINT=3
KIND=NET
VALUE=0

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
configuration 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.
10.1 The Serial Command Set
The serial command set can be divided into five groups: key press commands, USB 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 verifies that the
command was received and has been executed. If the command is unrecognized or cannot be executed, the
indicator responds with ??.
10.1.1 Key Press Commands
Key press serial commands (see Table 10-1) simulate pressing the keys on the front panel of the indicator. These
commands can be used in both setup and weigh mode. Several of the commands serve as “pseudo” keys, providing
functions that are not represented by a key on the front panel.
For example, to enter a 15-pound tare weight using serial commands:
1. Type K1 and press Enter (or RETURN).
2. Type K5 and press Enter.
3. Type KTARE and press Enter.

RESETCONFIGURATION: Restores all configuration parameters to their default values (setup mode only). The
RESETCONFIGURATION function can also be initiated by pressing the Reset Config softkey under the VERSION
menu. Use the up key to select Clear entire indicator configuration, then press Enter to reset the indicator.
Note All load cell calibration settings are lost when the RESETCONFIGURATION command is run.
Serial Commands
99
10.1.5 Parameter Setting Commands
Parameter setting commands allow the display or change of the current value for a particular configuration
parameter (Tables 10-4 through 10-13).
Current configuration parameter settings can be displayed in either setup mode or weigh mode using the following
syntax: command<ENTER>
Most parameter values can be changed in setup mode only; setpoint parameters listed in Table 10-7 on page 105
can be changed when in weigh 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 an incorrect command is typed,
the display reads ??.
For example, to set the motion band parameter on Scale #1 to 5 divisions, type the following:
SC.MOTBAND#1=5D<ENTER>
For parameters with selectable values, enter the command and equal sign followed by a question mark:
command=?<ENTER> to see a list of those values. The indicator must be in setup mode to use this function.
Some parameters are valid only if other parameters or parameter values are specified. See the configuration
Note menus in Section 3.2 on page 24 for information about parameter dependencies. Restrictions for front-panel
configuration also apply to serial command configuration.

10.1.8 Database Commands
The commands listed in Table 10-15 can be used to create and maintain databases in the 920i. Except for the
DB.DELALL 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 10-15. Database Commands
DB.ALIAS
The DB.ALIAS command is used to get or set the alias used by iRite programs to reference the specified 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 A–Z, a–z, 0–9, or an underscore (_).
Example. The following command assigns an alias of TRUCKS_2 to the first 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 10-16 into the first 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 10-16. 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 10-16, the indicator responds with the following data, using
pipe characters and carriage returns to delimit the database cells and rows, respectively:
this| is| a| test<CR>aaa| bbb|ccc|ddd<CR>
There is no end of database notification at the end of the DB.DATA command transmission. Use a receive
Note time-out to determine command completion. The time-out value will vary based on baud rate.
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.
The 62K of onboard (slot 0) memory can be allocated to up to eight auxiliary databases. However, the size of
Note any one database may limit the size and number of other databases.
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 A–Z, a–z, 0–9, or an underscore (_).
The <Data Type> is represented by a numeric field:

The DB.SCHEMA command can also be used to modify the schema, but only when the indicator is in setup mode
and only if the database does not contain any data.
10.2 Widget Programming
The type and location of elements shown on the 920i display are easily specified using the drag and drop features
of the iRev 4 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 configured.
Serial command widget programming is accomplished in setup mode, using the WDGT serial command. The first
parameter specified is the widget type, listed in Table 10-19. The following sections describe each of the widget
types and the parameters and values specific to that type.
In setup mode, the WDGT.CLR serial command can be used to clear all specified widgets from the display.

Setting the data_source of bargraph, label, numeric, and symbol widgets to 2 (program) allows these 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.
10.2.1 Scale Widgets
Scale widgets are used to present basic scale data from one or more configured scales. For multiple scale
applications, up to four scale widgets can be configured to be shown on the display at any one time. Fewer
displayed widgets allow each widget to be larger. Scale data from additional configured scales can be shown by
scrolling up or down through all configured scales, including a total scale widget, if configured.

scales_displayed = 1–4
screen_number = 1–10
Example:
WDGT#1=1,2,1,2<CR>
creates a single 1/2" scale widget for screen number 2.
10.2.2 Bitmap Widgets
Bitmap widgets provide a representation of vertical or horizontal tanks or a hopper. The location, size, and border
style of the widget are specified on the WDGT command.
WDGT#n=2, left, top, width, height,border_style, bitmap_widget_style, name/alias, visible, screen_number
where:
n=widget number
2= bitmap widget type
left = left edge location, in pixels
top = top edge location, in pixels
width = width, in pixels
height = height, in pixels
border_style = 1 (none)
bitmap_widget_style = 1 (vertical tank), 2 (horizontal tank), 3 (hopper)
name/alias = text name or alias
visible = 1 (on) or 2 (off)
screen_number = 1–10
Example:
WDGT#2=2,30,30,120,120,1,3,Hopper1,1,2<CR>
creates a visible, 1.5" x 1.5" (120 x 120 pixel) hopper widget for screen 2, named Hopper1, with no border, with
the upper left-hand corner of the bitmap at pixel location 30,30 (near upper left corner of display).
10.2.3 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.

data_field
If data_source = 1, data_field is the scale channel number
If data_source = 3, data_field is the setpoint number, 1–100, or 0 (current setpoint)
data_subfield
If data_source = 1, data_subfield is 1 (gross), 2 (net), 3 (displayed value)
If data_source = 3 and bargraph_widget_style is 2, data_subfield is the current value of the setpoint.
visible = 1 (on) or 2 (off)
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.
10.2.4 Label Widgets
Label widgets are used to insert a text label in the display.
WDGT#n=4, left, top, width, caption, border_style, justification, font_size, name/alias, data_source, data_field, data_subfield,

11.1 Troubleshooting
Table 11-1 lists general troubleshooting tips for various hardware and software error conditions. See the following
pages for additional information about specific diagnostic tools. Additionally, the CPU board has diagnostic LEDs
that flash when sending/receiving data, and a heartbeat LED for troubleshooting.
Symptom
Cause/Remedy
Indicator does not power up
Front panel power indicator blinking (
Possible blown fuse or bad power supply.
Check all voltages on CPU board. Power supply should output both +6V and –
6V levels to the CPU board (see Figure 2-5 on page 12). If power supply
appears bad, check the small glass fuse (2.5A, 5x20mm PN85791) on the
power supply board.
)
"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.

Table 11-1. Basic Troubleshooting
Appendix
119
11.1.1 Option Card Diagnostic Errors
Option cards are detected by the 920i at power-up. If the current indicator configuration 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, 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 reconfigure to eliminate the requirement for the option.
• Go to the VERSION menu and use the Reset Config softkey (or RESETCONFIGURATION command) to
perform a configuration reset. Configuration reset returns all configuration values to their factory defaults.
See Section 11.1.2 below, for information about using the HARDWARE serial command to verify that installed
cards are recognized.
11.1.2 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 1–14:
HARDWARE=3,3,2,4,5,0,0,0,0,0,0,0,0,0
Table 11-2 lists the card codes returned by the HARDWARE command.

Note The standard 10M/100Mbps Ethernet card does
not return a card type code. Any slot containing a
standard Ethernet card will return a value of 0 on
the HARDWARE command.
Table 11-2. HARDWARE Command Option Card Codes
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 configuration again. If
the card is still not recognized, try installing it in another slot.

920i Programmable HMI Indicator/Controller
11.1.3 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, 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 Rice Lake Weighing Systems technical support.
Note All A/D scales need to be loaded with a 350 ohm resistor for the iRite start up handler to run.
Diagnostic Boot Procedure
If a user program causes an error in the start-up handler, press and hold the setup switch while cycling power to the
920i to place the indicator in setup mode. Use iRev 4 monitor mode to send the PCLR command erase clear the
user program.
If the error is still not cleared, perform the following diagnostic boot procedure.
1. Disconnect power to the 920i.
2. Connect the serial port of a PC with iRev 4 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 2-5 on
page 12).
4. Power up the 920i. The indicator will stall at the diagnostic monitor.
5. Start iRev 4 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.
11.1.4 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
configured scales.
If more than one error condition exists, the number returned is the sum of the values representing the error
conditions (see Table 11-3 on page 121). 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.

11.3 Keyboard Interface
11.3.1 Serial 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 11-6 summarizes the 920i-specific functions provided by the keyboard interface; most other alphanumeric
and navigational keys provide functions equivalent to those typical for PC operation. Menu parameters and serial
commands that affect indicator keypad operation (including the KBDLCK, ZERONLY, and KLOCK serial
commands) also affect the remote keyboard.
Note
• The keyboard interface is not hot-pluggable. Disconnect power to the 920i before plugging the keyboard cable into the
Port 2 connector.
• The 920i supports keyboard scan codes 1, 2, and 3.
Appendix
123
11.3.2 USB Interface
The 920i USB interface board provides a type-A connection for a USB keyboard interface. To use the keyboard
interface, set the DEVICE parameter for Port 2 (under the SERIAL menu) to KEYBOARD.
Table 11-6 summarizes the 920i-specific functions provided by the keyboard interface; most other alphanumeric
and navigational keys provide functions equivalent to those typical for PC operation. Menu parameters and serial
commands that affect indicator keypad operation (including the KBDLCK, ZERONLY, and KLOCK serial
commands) also affect the remote keyboard.

11.4 Serial Scale Interface
Serial ports 3 through 32 can be configured 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 configured to accept scale
data, the data format can be customized to match the data stream sent by that indicator.
To configure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT parameter for the selected port to SCALE (Legal for Trade serial
scale) or INDUST (industrial serial 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.
3. Under the SERIAL menu, return to the selected port and set the format under the SFMT parameter to
match the format sent by the serial scale.
The default serial scale format is:
<2><P><W7.><U><M><S><CR><LF>
where:
<2>
<P>
<W7.>
<M>
<U>
<S>
<CR>
<LF>
STX character
Polarity
Seven characters of net data with decimal point
Mode
Units
Status
Carriage return
Line feed
Industrial serial scales (INDUST) do not require the <M>, <U>, and <S> identifiers. However, the units and
Note number of decimal places must be specified. Units can be selected from the FORMAT menu; decimal places
should be indicated on the w-spec identifier. For example, a seven-digit weight requiring two decimal places
should be specified as <W7.2> rather than <W7.>.
124
920i Programmable HMI Indicator/Controller
See Section 11.6 for more information about stream formatting and format identifiers.
iRev 4 provides several preset scale formats within its Stream Formatting function. Figure 11-1 shows one of the
iRev 4 stream formatting displays.
Figure 11-1. iRev 4 Stream Formatting Display
11.5 Local/Remote Operation
For truck scale and similar applications, local/remote support provides function equivalent to that of a legal-for-trade remote
display with keypad. Scale data from the local indicator is also displayed at the remote unit, and keypad input from the
remote allows transactions to be initiated from either the local or remote unit.
To configure for local/remote operation, first set up the local scale (including softkey assignments, truck mode, and
database information, as required). Use the SERIAL menu, serial commands, or iRev 4 to set the Local Unit serial
parameters shown in Table 11-7. Configure the remote indicator using the serial parameters listed for the Remote
Unit.

11.6 Custom Stream Formatting
Each port can be independently configured to stream a default frame format or can be customized to stream a userdefined format. Custom formatting is very similar to the standard print formatting described in Section 7.0.
Table 11-8 on page 126 lists the format identifiers used to configure a custom stream format. See Section 11.7 on
page 128 for examples of custom stream formats.

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.

Status:
<space> = valid
I = Invalid
M = Motion
O = Over/under range
Z = Center of zero
Figure 11-2. Continuous Output Serial Data Format
Demand Output Serial Data Format
When demand mode is configured 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 configuration.
To customize the ticket to work with a wide variety of printers, scoreboard displays, and other remote equipment.
See Section 7.0 on page 69 for more information on custom print formats.
RS-485 Data Formats
Two-wire RS-485 communications is available on port 4 of the CPU board; four-wire RS-485 communications is
supported on the “A” ports of any installed serial expansion cards.
The 920i has a built-in RS-485 software protocol which is enabled when assigned a non-zero address to the
indicator. Valid RS-485 addresses must be in the range 1–255; the address is specified on the ADDRESS parameter
on the SERIAL menu.
All remote commands are initiated using the data format shown in Figure 11-3:
<STX>
<ADDRESS>

renders all indicators unable to
respond to serial commands.
Figure 11-3. RS-485 Send Data Format
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 an XG#1 command, the responding indicator uses the format
shown in Figure 11-4:

11.9 Digital Filtering
Standard digital filtering uses mathematical averaging to eliminate the variant digital readings that the A/D
converter sends periodically because of external vibration. Digital filtering does not affect the indicator
measurement rate, but does affect the settling time. The selections from 1 to 256 reflect 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.
DIGFLTx Parameters
The first three digital filtering parameters, DIGFLT1, DIGFLT2, and DIGFLT3, are configurable filter 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 filter stage before averaging.
A rolling average is passed to successive filters for an overall filtering effect that is effectively a weighted average
of the product of the values assigned to the filter stages (DIGFLT1 x DIGFLT2 x DIGFLT3) within a time frame
corresponding to the sum of the values (DIGFLT1 + DIGFLT2 + DIGFLT3).
Setting the filters to 1 effectively disables digital filtering.
RATTLETRAP® Filtering
RATTLETRAP digital filtering (RATTRAP parameter set ON) uses a vibration-dampening algorithm to provide a
combination of the best features of analog and digital filtering. 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 flaws. It is particularly effective for eliminating vibration effects or mechanical
interference from nearby machinery. Using RATTLETRAP filtering can eliminate much more mechanical
vibration than standard digital filtering, but will usually increase settling time over standard digital filtering.
DFSENS and DFTHRH Parameters
The digital filter can be used by itself to eliminate vibration effects, but heavy filtering also increases settling time.
The DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to
temporarily override filter averaging and improve settling time:
• DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold
(DFTHRH) before digital filtering is suspended.
• DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale readings
(DFSENS) fall outside of this threshold, digital filtering is suspended. Set DFTHRH to NONE to turn off the
filter override.
Setting the Digital Filter Parameters
Fine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments.
Use the following procedure to determine vibration effects on the scale and optimize the digital filtering
configuration.
1. In setup mode, set the digital filter parameters (DIGFLT1–DIGFLT3) 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.
132
920i Programmable HMI Indicator/Controller
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.
Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.
11.10 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 specified on the FORMAT menu using the SECNDR and TERTIA parameters,
or by using serial commands.
• To configure secondary or tertiary units using the front panel menus, use the Table 11-12 to find 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 configure secondary or tertiary units using serial commands, use the Table 11-12 to find 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.
Ensure that the secondary decimal point position is set appropriately for the scale capacity in the secondary
Note units. If the converted value requires more digits than are available, the indicator displays an overflow 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 overflow 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 five digits to the left of the decimal point to display
the 10000 lb secondary units value.

11.11 Audit Trail Support
Audit trail support provides tracking information for configuration and calibration events. A separate calibration
counter is provided for each scale; a single configuration counter tracks all configuration changes.
To prevent potential misuse, unsaved configuration or calibration changes are counted as change events;
restoration of the previous saved configuration or calibration is also counted.
11.11.1 Displaying Audit Trail Information
To display audit trail information, press and hold the Gross/Net key for several seconds. Various audit trail
information screens can then be accessed by pressing the front panel number keys (1–7 and 0). The exact format of
each screen depends on the regulatory agency specified for the REGULAT (FEATURE menu) parameter.
The initial screen shown when entering the audit trail display (or whenever the 1 key is pressed while showing
audit trail information) shows the legally relevant (LR) version number (software version for the code that provides
audit trail information), a calibration count and, if REGULAT=NTEP, a configuration count.
Press 2 to show the configuration count display. This display shows the number of times the system has been
configured, the date and time of the last configuration event, and the before and after information for the most
recent change of the system date and time.
Press the Down key to show the number of weighments, number of configuration events, number of calibrations,
and the date and time of the most recent calibration for the first configured scale. Continue pressing the Down key
to cycle through the information for all configured scales.
Press 3 to show the number and the most recent date and time of power-on events, power-on configuration changes,
and user program loads.
Use the Down key to show the number of power-on calibration events for all configured scales.
Press 4 to show the number of times the OEM version number has been changed, and the date and time of the most
recent change.
Press 5 to show the number of times the configuration has been reset, the date and time of the most recent reset, and
the indicator EIN number.
Press 6 to show the manufacturer of the indicator.
Press 7 to show the number of core loads, and the date and time of the most recent.
Press 0 to show the indicator and LR software versions.
When done, press the Gross/Net key to exit the audit trail displays.
11.11.2 Printing Audit Trail Information
Audit trail information can be printed by pressing the PRINT key while displaying the audit trail or by sending the
DUMPAUDIT serial command. Audit trail information is sent to the port specified on the AUD.PORT serial
command or by the AUDFMT parameter (PFORMT menu).
Printed audit trail information contains data for all scales, whether configured or not, that can be supported by
Note the indicator. Displayed audit trail information shows data only for currently configured scales.
