sal
Most of the payment systems complete with a BDV pro-
tocol is intended to manage the free sale function.
However, there are some payment systems not having
this function.
In this case, it is necessary to enable the VMC (vending
machine control, disabled by default) free sale and to
set the price of selections to zero if some selections are
dispensed on a free basis.

The MDB protocol menus enable the user to define the
following functions.

automatically given at the end of a successful delivery,

enabled), the remaining credit will be returned up to the
maximum change value.
