Counters
Counter commands can be a numeric value from 00000 to 65,535. After reaching the
maximum numeric limit of 65,535, the counter will automatically roll-over and start
counting again at 00000. To obtain the cumulative total of counts after the roll-over
has occurred, add 65,536 per each roll-over (the scanner does not keep track of the
number of roll-overs) to the current count.
Note: All counter values will be lost if power is recycled to the scanner or the scanner
receives a reset or save command.
