Additionally, the MDB protocol is a synchronous serial protocol, which means that it requires a clock signal to synchronize the communication between devices. This clock signal is typically provided by the vending machine's control board, so it may not be possible to use the MDB protocol without an existing vending machine interface.

Finally, while the MDB protocol is a well-established standard, there may be variations in implementation between different manufacturers or models of vending machines. It's important to ensure that any peripheral devices you are using with the MDB protocol are compatible with the specific vending machine you are working with.

Overall, the MDB protocol can be a powerful tool for vending machine integration, but it's important to understand the technical limitations and requirements before getting started.

MDB in the vending industry

Thu, 05 Jan 2023 12:07:00 +0100

MDB, or Multi Drop Bus, is a standard protocol used in vending machines and other self-service kiosks to allow for communication between the payment system and the vending machine or kiosk. It allows for the exchange of data such as the selection of products, the acceptance of payment, and the dispense of products.

One of the main problems that MDB solves is the need for a standardized communication protocol between payment systems and vending machines. Before the adoption of MDB, each vending machine manufacturer used their own proprietary protocol, which made it difficult for payment system providers to integrate with multiple vending machine brands. MDB provides a common language that can be used by all parties, making it easier for payment systems to work with a wide range of vending machines. MDB also allows for the integration of advanced payment methods, such as credit card readers and mobile payment systems, into vending machines. This increases the convenience for customers and can lead to increased sales for vending machine operators.

Overall, the use of MDB in the vending industry has helped to standardize communication between payment systems and vending machines, making it easier for payment system providers to enter the market and for vending machine operators to accept a wider range of payment methods.

Restrictions of the MDB Protocol

One issue that can arise with the MDB protocol is the need for precise timing of the communication between the payment system and the vending machine. The MDB protocol requires that the payment system and vending machine maintain a strict timing relationship in order to properly exchange data. If the timing is not correct, it can result in communication errors and the transaction failing. Another issue that can arise with the MDB protocol is the limited number of available commands. The protocol only defines a small number of commands, which can limit the flexibility of the system. For example, it may not be possible to add new features or functionality to the vending machine if there are no available commands to support them.

The devices communicate in a single-master, multiple-slave configuration using the MDB protocol which is based on 9-bit, implemented as an 8-bit data value with an additional mode bit. The mode bit differentiates between ADDRESS and DATA bytes. The master sends messages containing one address byte and a variable number of data bytes. The bus "slave devices" listen for an address, and if it matches their address that slave device will process the message and respond to the master.

The MDB-Converter handles the 9-bit data format and makes sure timing is correct.

MDB Converter: your reliable Interface for Multi Drop Bus controlled devices

Tue, 01 Nov 2022 14:36:00 +0100

If you look for an easy way to upgrade your vending machine with a modern IT device, get our MDB Converter. It allows to connect the vending controller to modern IT solutions such as Linux, Android, or Windows devices. The MDB Converter is a reliable Interface for Multi Drop Bus controlled devices.

The converters use a proprietary serial protocol called CP (Control Protocol) to talk to your application. This protocol only frames the MDB payload and does not put constraints on the MDB messages or behavior. This means that the converters do not implement MDB behavior themselves, which gives you the full control over the messages and behavior.

You can therefore send any MDB data to the bus or implement any MDB behavior you would like. This is an easy interface to the raw MDB bus messages, so any peripheral and master function can be implemented.

Several product versions help you to fulfill all your requirements. We provide

MDB Bus with stabilized 5V power @ 1A (up to 5W) output
an SDK that gives you a fast start for developers
a Raspberry PI Hat to use your Raspberry PI as an VMC and even logging and tracing possibilities.

Internet of things (IOT) for vending: MDB Raspberry Pi HAT (Multi Drop Bus)

Mon, 20 Nov 2017 02:00:00 +0100

If you want to upgrade your vending machines with a modern controller based on Raspberry PI, you can use our MDB (Multi Drop Bus) hat to connect you Raspberry Pi to the vending machine.

The internet of things (IoT) is fast approaching and will affect every area of our lives. This will equally be true for the vending industry. That’s why we have created an MDB Raspberry Pi HAT.

While many vending machines these days are already connected to the internet, in cases this is still considered an “add-on”, or a telemetry unit. This means there is an old-school VMC (vending machine controller) that talks MDB. MDB is a 9 bit protocol (yes, you read correctly) designed around a bus where peripheral devices can be attached. It has strict and very short timing constraints. The internet add-on is then either attached to this bus or the the VMC.

MDB was clearly designed for hardware components that run some sort of low-level firmware that implements the protocol. It does not suit modern, state of the art software solutions. We made this discovery when we created our first MDB cashless peripheral. Soon we realized that we needed a piece of hardware that enables integration with MDB. You can read more about this experience here.

You may ask why MDB was not replaced decades ago? There are probably multiple reasons for this:

Long investment cycles for vending machines.
VMCs use firmware that cannot just be updated to something new. Someone has to go there to update the machine.
There are many MDB peripheral devices available that might not offer any other interface. For example coin changers or bill validators. These are still crucial parts of a vending machine.

There are more modern vending machines out there today, but the vast majority will still use MDB.

Innovative Vending Machines

So how to create a more modern vending machine? After we created our first cashless peripheral, we released the MDB Converter 3, which takes care of the difficult parts of the MDB specification and provides a simple interface for modern devices (USB, serial and Low Voltage TTL). This is what we used back then in our cashless peripheral. On top of that we used some processor board and created our own hardware. This was before Raspberry Pi and Arduino. Today, we would of course do this using an MDB Raspberry Pi HAT, which we now have created.

We are proud to release this new product called MDB2Pi. It is an MDB Raspberry Pi HAT and some of its features are:

Can be used as MDB VMC or MDB cashless peripheral
Supports MDB Logging/Tracing
Has a Real Time Clock (RTC)
Powers the Raspberry Pi through the MDB bus
Provides a low level API to send and receive MDB messages. It does not alter the MDB payload, which gives you the full control over the MDB implementation.
We provide sample implementations of the API in C# (SDK)

This product will give you the power to create a modern vending machine, because you can delegate the old-school MDB stuff to the MDB2Pi, while you have state of the art options on your Raspberry Pi. Imagine you can update your VMC software remotely. Imagine you can turn features on and off remotely and much more. Without any other extra add-ons. I am sure you will have many and much better ideas than these…
