Rice Lake 920i USB Installation Manual V5.05 - Manual (Page 13)

Introduction 7
Version 3.13
• Added a new value <AN> to the Print Formatting
section of the manual (see Section 6.1, Table 6-1 on
page 60).
• Corrected comparisons to reduce the number of
power-up calibrations counted by Audit Trail.
• Added the speed-up of loading a user program by
only erasing needed memory blocks.
Version 3.10
• Error Recovery - version 3.10.00 of the 920i now
has a very sophisticated error recovery for the
battery backed NVRAM. when a Save and Exit is
performed after a Configuration and Calibration is
performed, a copy of the NVRAM is stored in Flash
for future recovery. If the 920i is powered off at any
time and the battery is not at peak performance, the
NVRAM could come up with corrupted data. The
next time the 920i is powered up, the NVRAM is
tested for a correct CRC checksum. If this is bad,
there will be a special screen displayed showing the
corrupt locations with directions to press ENTER to
continue. The core will rewrite to NVRAM using
the last copy of the last Save and Exit. At this time
Date and Time are also checked. It will then open
the Date/Time full screen edit function so the
operator can check the current Date and Time. If
correct, all that is needed is an ENTER key to
continue. If incorrect, the operator can adjust the
Date or Time and then push ENTER to continue.

To ensure the latest copy of NVRAM is available
for a power up, it is recommended that before
powering down the 920i for either overnight outage
or temporary storage, the unit should be put into
setup mode and a Save and Exit performed which
will save a new copy of the NVRAM. On
Legal-For-Trade units, if this cannot be performed,
then the system will use the last Save and Exit and
all databases and truck data should be uploaded to a
PC prior to powering the 920i down.
• Removed the EXIT key during Setup mode.
• Added a progress message during the clear of
memory and loading a user program (see
Section 5.6.1 on page 62)
Version 3.09
• The battery replacement procedure has been
updated (see Section 2.8 on page 17).
• A TOKENS parameter has been added to the
SERIAL menu to allow changing the data stream
tokens from the indicator front panel (see
Section 3.2.2 on page 37).
• Values for SWAP parameter on the FLDBUS menu
have been changed to allow greater flexibility in
byte-swapping for fieldbus cards (see Section 3.2.8
on page 55).
• Improved database handling. Database access by
multiple simultaneous requests is now controlled by
allowing one read or write operation at a time, on a
first-come, first-served basis.
Version 3.08
• A new value, KBDPRG, on the Port 2 serial menu
allows keyboard scans to be passed directly to an
iRite user program (see Figure 3-8 on page 37).
• Support for negative tracking has been added to the
ALGOUT menu (see Section 3.2.7 on page 54).
• A new stream token, Z, has been added to the <S>
stream format status identifiers to indicate
center-of-zero (see Table 11-8 on page 118).
Version 3.07
• Support has been added for the dual-channel analog
output card (PN 103138) and the ControlNet
interface card (PN 103136).
• New OVRBASE parameter, on the REGULAT
submenu of the FEATURE menu, allows
specification of calibrated or scale zero as the base
for overload calculation. See page 49 for more
information.
• A new top-level menu, FLDBUS, is now shown if a
DeviceNet, Profibus, EtherNet/IP, or ControlNet is
installed.The two parameters under the FLDBUS
menu allow byte swapping to be enabled (SWAP
parameter) and for the transfer size of the swapped
bytes to be specified (DATASIZE). See
Section 3.2.8 on page 55 for more information.
• The default A/D sample rate (SMPRAT parameter
on the SCALES menu) has been changed from 120
to 30 Hz.
• The KEXIT command has been removed and
replaced with KSAVEEXIT. (See Section Table
10-1. on page 94.)
• Error codes returned on the XE serial command
have been updated (see Table 11-3 on page 114).
Version 3.05-3.06
• Support for local/remote indicator configurations
provides function equivalent to a legal-for-trade
remote display with keypad for truck scale and
similar applications. See Section 11.5 on page 117
for more information.
• The description for setting rate of change (ROC)
parameters has been changed. See Table 3-3 on
page 31 for details.
• New values have been added to the STREAM
parameter on the SERIAL menu to allow streaming
of keypad events to another indicator (4KEYS,
KEYPAD) and, for the local/remote function, to
send the complete display image (DISPLAY). See
Section 3.2.2 for more information.
• Reprinting of any previous print transaction is now
