MDB Upgrade

MDB Interface

Build and Upgrade MDB Vending Machines

The MDB standard is not so easy to understand and implement, as it uses unusual communication technologies. With the MDB-USB interface, Qibixx offers an easy way to connect the MDB world with the modern IT world.

Master: Developers can easily connect MDB peripherals to PCs or small Linux controllers using the MDB interface in Master mode, for example, to build a machine with a coin validator. Sample software available from Qibixx upon request.

Slave: To connect a machine to a payment system, the MDB controller is used as a “Slave” and it can then, for example, simulate a cashless device. Optionally, Qibixx offers the “Cashless Daemon” (software module), which can be accessed from the software environment – Thus, no MDB protocol knowledge is necessary.


Optionally usable as Master or Slave.
