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.

"CHICAGO — 2019年8月22日 — NAMA 发布了最新版自动售货机MDB协议 V4.3.

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 protocol (MDB中文协议) 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)

MDB protocol (MDB中文协议) 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. Previous work arounds have been

I want to connect a RS232 payment module to the NECTA coffee vending machine, can I use it?

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".

什么是MDB协议?

MDB是MDB/ICP协议(Multi-Drop Bus/Internal Communication Protocol)的简称,它是欧洲自动售货机制造者协会制定的一套用于协调自动售货系统的主控制器(VMC)与多个外设之间通信的协议。标准首先是由Coinco在美国可口可乐公司的指定下开发的。这个标准于1993年被NAMA组织采用;经过NAMA修订后,于1994年被EVMMA采用。第二阶段的非现金交易标准由Debitek代表NAMA开发,并于1994年被NAMA采用;EVMMA加入了一些兼容的指令后于1994年采用。MDB接口实际上是工作于9600波特率的主从型串行总线接口,所用外围设备(例如投币器、纸币器、读卡器等)均为主控制器(售货机控制器-VMC)的从机。所有外围设备与VMC之间的通信方式都一致。

Eight changes to the cashless device(s) section on MDB V4.3 protocol

1. Allows reporting the item number dispensed to the cashless device.
2. New “Remote Vend” provides a method that allows the MDB cashless protocol to run a product dispenser on the VMC. For example, a mobile phone application can select products on the phone screen without touching vending machine buttons / screen.
3. New “Basket / Partial Refund” feature allows multi-vends in the MDB Cashless session in a single transaction (i.e.; single card touch). It informs the cashless device about each dispensed product (providing item number of each).
4. New “Basket / Partial Refund” feature also allows partial refunding for cases when a part of product was not dispensed (i.e.; multi-vend product not dispensed, liquid dispensing machine with stop button, etc).
5. New “Coupon” feature provides a method to accept coupons in the MDB cashless protocol. For example, prepaid coupons could be scanned to allow the cashless device to insert prepaid credit in addition to standard cards with credit holding. Another example would be a QR-code for free vend of the specified product.
6. Allows the VMC to take into consideration card information (Funds available, Payment media ID, Type of payment) in case of selection first.
7. Adds the enhanced item number information. Adds the Item Number Dispensed and the EVA-DTS PA101 field for item Selected and Dispensed to the 7.4.7 Vend Success and 7.4.10 Cash Sale commands.
8. Adds a new “Mixed Vend Flags” byte to the CASH SALE command.
