MDB tracing with the Sielaff Redbox

Introduction

The "tracing" is a recording of the MDB communication in the machine, we use the Redbox in the "Black edition" from Sielaff as an aid. Recordings of the MDB communication can be evaluated by us for error analysis. The recordings are saved on a micro SD card located in the Redbox. The Redbox has a mini-USB connection and can be connected to a PC, where the Redbox behaves like a USB stick.

Preparation

Ideally, two Redboxes are required for recording in connection with a Vencube. One Redbox is connected to the Vencube on the master side and the other on the slave side. To distinguish between the red boxes later, it makes sense to label them, e.g. with master (machine control) and slave (credit systems).

Required:

• 2x red box
• Windows PC with a free USB port
• USB Cable (USB-A ⇔ USB-Mini-B)

Connecting the Redboxes

1. Turn off the vending machine.
2. Connect the two redboxes as in the picture below.
3. The section Tracing continues...

  Redbox Anschluß

The Redbox has an MDB plug and an MDB socket on the connection cable. It is simply smuggled in between Vencube and the VMC or between Vencube and the payment systems.

Redbox 1 for the VMC side (master)

Redbox 2 for the slave area (slave)

Before connecting the Redboxes, the machine must be switched off!
