NAMA Releases MDB Version 4.3
"CHICAGO — August 22, 2019 — NAMA announced today the release of the latest version of the Multi-Drop Bus (MDB) standards – Version 4.3.
The MDB stands for “multi-drop bus” and describes the computing language used by most vending machines. The MDB protocol operates the VMC or vending machine control board. This language transfers information from the vending machine itself to the coin counting mechanism, the bill validator and the credit or debit card reader. These three things are considered peripherals. The MDB protocol ensures that payments are processed correctly and efficiently and that they trigger the appropriate response in the vending machine i.e. releasing the chosen snack.
MDB Protocal (MDB协议) V3.0!
Version 3.0 of this specification is the third release of the international Multi-Drop Bus / Internal Communication Protocol (MDB / ICP). This specification is the continued effort put forth by technical members of NAMA and the EVA. The basis for this specification is the Version 2.0 international Multi-Drop Bus / Internal Communication Protocol (MDB / ICP) released on October 4, 2002.
Of special note are the four major changes that were made to the specification:
• Added a second Cashless Device peripheral address in Section 7
• Replaced the Audit Unit with the Communications Gateway in Section 8
• Added the Coin Hopper or Tube – Dispenser in Section 10 (new)
• Assigned 2 addresses to be used for experimental peripherals
MDB Protocal (MDB协议) V4.2!
Version 4.2 of this specification is the sixth release of the international Multi-Drop Bus / Internal Communication Protocol (MDB / ICP). This specification is the continued effort put forth by technical members of NAMA and the EVA. The basis for this specification is the Version 4.1 international Multi-Drop Bus / Internal Communication Protocol (MDB / ICP) released in July, 2010. There is just one major change within cashless device(s) section, related to cashless devices commonly new in public (credit card) transactions. These devices, especially contactless operated, need an uninterrupted transaction starting with the actual correct vend price and therefore are not able to deliver a begin session in front of the transaction.

This specification is the continued effort put forth by technical members of NAMA and the EVA.

Nayax VPOS
Yes, of course,NAYAX, PAX IM30 and so on, these applications are very stable. Many customers use it.
Pax solution
No. The RS232 serial port of MDB-RS232 adapter is connected to the vmc board. The VMC board control the MDB payment device through the RS232 port, that is, the MDB adapter and the vmc board together act as the host machine.
Your requirement is that the MDB adapter and the payment module work together as a payment module, acting as slaves to the existing NECTA coffee vending machine. So you need to use "RS232-MDB", not "MDB-RS232".

If you choose a product from an unstable company, after you complete the design, the supplier company may go bankrupt, business changes, product discontinuation, product quality issues and other accidents may occur, resulting in the embarrassment that you cannot continue to buy. Or after encountering some product or technical problems, customer will never get technical support or solutions.
3. We have a competitive price. Of course, for self-service vending products, price is definitely not the most important thing, because stability is very important in unattended situations. Only then can the machine generate trouble-free benefits for customers.
