As an odditythe machines that use ID bill acceptors are also using ccTalk for the coin acceptor and coin hopper. Is widely spread in the gaming industry. IDDriver-BasicDistributable Aplication ID protocol — If you design a simple low security toy machine protoocol most suited will be one the first four protocols: To find out more, including how to control cookies, see here: Most low price coin and bill acceptors have this protocol lrotocol by firmware or dip-switch or other settings. On coin hoppers there is an input that runs the hopper motor and an output that send a pulse for each coin paid.

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. There is no error recovery , some security can be reached by tightening the acceptable pulses width error accepted.
Most low price coin and bill acceptors have this protocol available by firmware or dip-switch or other settings. At a minimum only one data input is needed on the host machine.
Parallel pulse protocol Only for coin and bill acceptors. If you use also the individual enable inputs you will have a large data bus , with large connectors. The security is somehow higher due the redundancy in the data received by the host machine. Binary parallel Is a variant of parallel pulse protocol where a the outputs are valid only on the edge of a clock line , this allow using combinations to represent the bill channel so 16 bills can be signaled using 4 data outputs and a clock line.
MDB serial protocol Is a serial protocol designed for vending machines , the security is pretty high with error recovery , many kind of devices can be driven including cashless audit and age verification devices. As a workaround the serial port must be reset at the runtime or some kind of translation hardware interface must be used. There is also support in the protocol for power management.
Is widely spread in the gaming industry. It also uses optically insulated RX and TX lines at bauds 8 bit data 1 even parity bit and an optional hardware reset line. Can be run over serial to USB converters. The integrity of data packets is protected with a CRC16 check-sum.
The specifications can only be obtained from JCM after signing a non disclosure agreement. The use for host machines is free as far as I know , for slaves a per unit fee must be paid. As an oddity , the machines that use ID bill acceptors are also using ccTalk for the coin acceptor and coin hopper.
The interface is simple just one bidirectional data wire ,PC friendly and easy to implement even on a low resources micro controller. CcTalk is free to use for slaves and host to and any producer has ccTalk version of their products. The software you will make will be reusable on cheap or expensive devices as you need. Why not USB protocol? Yes and no. Keep in mind , any trustworthy producer will have some ccTalk version of his product.
