5.5 MDB
5.5.1 General Description
MDB (Multi-Drop Bus) is an open standard in the vending industry specified by
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). Currently only the
NV200 and the NV200 with the Payout module are compatible. MDB documentation
can be found in Section 1.1.

5.5.3 IF5 Interface
The IF5 allows the NV200 to operate with MDB machines no matter the voltage
(24/34/48). As the NV200 can operate at 24v this is only required for applications
higher than 24v.
A link to the IF5 can be found below.
