moisture from entering the enclosure.
opening the unit, ensure the power cord
is disconnected from the power outlet.
2.3.1 Cable Grounding
Except for the power cord, all cables routed through
the cord grips should be grounded against the
indicator enclosure. Do the following to ground
shielded cables:
¥ Use the lockwashers, clamps, and kep nuts
provided in the parts kit to install grounding
clamps on the enclosure studs adjacent to cord
grips. Install grounding clamps only for cord
grips that will be used; do not tighten nuts.
¥ Route cables through cord grips and grounding
clamps to determine cable lengths required to
reach cable connectors. Mark cables to remove
insulation and shield as described below:
¥ For cables with foil shielding, strip insulation
and foil from the cable half an inch (15 mm)
past the grounding clamp (see Figure 2-1).
Fold the foil shield back on the cable where
the cable passes through the clamp. Ensure
silver (conductive) side of foil is turned
outward for contact with the grounding
clamp.
¥ For cables with braided shielding, strip cable
insulation and braided shield from a point just
past the grounding clamp. Strip another half
inch (15 mm) of insulation only to expose the
braid where the cable passes through the
clamp (see Figure 2-1).

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.

3.0 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
Save and Exit softkey to exit setup mode, then replace
Exit or
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
utility.
NOTE: Some conÞguration parameters, such as those
used to conÞgure the
920i display and widgets, cannot
be accessed through the conÞguration menus.

interface for the
3.1.1 iRev Configuration
920i.
The iRev conÞguration utility provides the preferred
method for conÞguring the
on a personal computer to set conÞguration
parameters for the indicator. When
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.

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

using
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.

Specifies the number of full scale graduations.
The value entered must be in the range 1–9999999 and should be consistent with legal
requirements and environmental limits on system resolution.
To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions.
Display divisions for primary and secondary units are specified under the FORMAT
submenu.
See Level 4 submenu descriptions in Table 3-3 on page 26.
Automatically zeroes the scale when within the range specified, as long as the input is
within the ZRANGE and scale is at standstill. Selections are ± display divisions. Maximum
legal value varies depending on local regulations.
Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9%
around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to
zero the scale. Use 1.9% for legal-for-trade applications.
Sets the level, in display divisions, at which scale motion is detected. If motion is not
detected for 1 second or more, the standstill symbol lights. Some operations, including
print, tare, and zero, require the scale to be at standstill. Maximum legal value varies
depending on local regulations.
If this parameter is set to OFF, the standstill annunciator does not light; operations normally
requiring standstill (zero, tare, print) are performed regardless of scale motion. If OFF is
selected, ZTRKBND must also be set to OFF.
Specifies the length of time the scale must be out of motion, in 0.1-second intervals, before
the scale is considered to be at standstill. Values entered must be in the range 1–65535.
Determines the point at which the display blanks and an out-of-range error message is
displayed. Maximum legal value varies depending on local regulations.
Selects the digital filtering rate used to reduce the effects of mechanical vibration from the
immediate area of the scale.
Choices indicate the number of A/D conversions per update that are averaged to obtain the
displayed reading. A higher number gives a more accurate display by minimizing the effect
of a few noisy readings, but slows down the settling rate of the indicator.

Hz value may be too fast to provide the desired stability in some static weighing
applications.
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.
