Counters

Counters
Counter commands can be a numeric value from 00000 to 65535. After reaching the
maximum numeric limit of 65,535, the counter will automatically rollover and start counting
again at 00000 and report any errors. To obtain the cumulative total of counts after the
rollover has occurred, add 65,536 per each rollover (the scanner does not keep track of
the number of rollovers) 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.
