These are the most common protocols used , I have tested more or less all of them:. Some have individual inputs to enable each coin or bill channel. On coin hoppers there is an input that runs the hopper motor and an output that send a pulse for each coin paid. This can be problematic on higher value bills or coins, for a Eur bill pulses must be sent , the probability that an error occur is pretty high.
