I. Device overview
This device was designed to offer a quick development support for cashless systems on
Executive vending machines and using MDB payment systems. It acts like a bridge
between any Executive machine and MDB payment systems (bill validator, coin
acceptor/changer and a cashless device). This device is working only with Level 3 or
higher coin changers, because it only supports alternative payout change mode of MDB
protocol.
IMPORTANT!!! - The machine must be set on Executive, either price holding mode (prices
are kept on the device not on the machine) or with prices on the machine. When the prices
are held on the machine, you will not be able to obtain a total value of sold products, unles
your application keeps the prices for each item, too.
It can be used on any Executive price holding vending machine with a maximum of 96
selections (products).
The device is self maintained and transparently manages the entire Executive, MDB and
transactions flow.
