MDB (Multi-Drop Bus) is used in the vending industry and is now an open standard
in the NAMA (National Automatic Merchandising Association) so that all vending and
peripheral equipment communicates identically. MDB uses a master-slave model
where the VMC (Vending Mechanism Controller) is the master that can communicate
with up to 32 slaves (e.g. banknote validator or coin acceptor). Please contact
