The serial interface is used to program coin data and customer options. It can also be used
instead of the parallel interface to communicate with the machine.
Note: The serial and parallel interfaces cannot be used together in the machine.
Protocol:
ccTalk
BACTA compliant implementation.
For further details on this section please refer to the current
