WI-125 SST Indicator Service Manual
Appendix 1: Earlier Versions of WI-125
All versions of the WI-125 LCD indicators, beginning with serial number
36898, have a new main board and firmware. The microprocessor has been
changed to its most current revision. This means the board layout changed,
along with a different EPROM and its stored firmware. EPROMs from the
former board will not work in this new board.
Previous models of WI-125 LCD indicators required an optional, special
software feature to add single channel accumulation and transaction count.
The enhanced WI-125 LCD configuration includes the choice to enable single
channel accumulation and transaction count.
Below is a chart referencing the model/part numbers for the old and new
board/EPROM:
