In this more complicated example, the hopper dispense count and the hopper life dispense
count end up with the correct values even though a coin was seen on the exit optos after the
motor stopped. For the host machine to find the correct value of unpaid coins it would need
to re-
send the ‘Emergency stop’ command or use the ‘Request hopper status’ command
before power was lost - otherwise it would think there were 7 unpaid coins rather than 6.
