1.5 Summary of Changes
Changes to recent editions of this manual are listed
below:
Version 4.0
• Added support for iQUBE 2 and removed
support for iQUBE .
NOTE: Version 4.0 requires Rev E CPU board or newer.
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, there is a copy
of the NVRAM that 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
