What is this device?
The GalaxyVend core board, when loaded with specific firmware, functions as a robust MDB to Executive protocol converter.

The key elements of GalaxyVend MDB to Executive converter

  1. Power flexibility.
    • The board is polarity-insensitive and can be powered by 24 to 36VDC. It also provides the necessary VDC for all connected MDB peripherals.
    • You can also use 7 to 24VAC to power the board.
  2. Internal Management: Transactions and change-returning logic are managed internally by the board.

    GalaxyVend MDB to Executive converter possible applications
    There are two distinct firmware versions available depending on your needs:

    Standalone firmware
    This version acts as a seamless adapter to connect MDB payment systems to Executive machines.

    • Connectivity: Supports 1 x bill validator, 1 x coin acceptor (or changer), and 1 x MDB cashless device (e.g., a credit card reader).
    • Credit Card Requirements: The reader must support MDB Level 2 and be configured for pre-authorization mode. Ensure your supplier confirms that the MDB cashless session begins only after the bank authorizes the transaction.
    • Configuration: Compatible with all Executive modes (Standard or Price Holding). For Price Holding mode, you can set prices directly in the converter using our Android configuration app.

      Externally handled firmware
      In this mode, the board acts as a bridge, allowing an external application to control the business logic via a USB interface.
    • Total Control: Your application handles cash/credit acceptance and approves product dispensing.
    • Advanced Features: Integrate customer identification using an optional RFID reader (requires WiFi and a SaaS backend subscription).
    • Connectivity: Supports MQTT over WiFi to connect directly to our SaaS backend.
    • Retrofitting & Telemetry: By adding the keypress expansion module, you can simulate physical button presses on a mechanical keyboard. This allows you to transform a traditional machine into a modern one controlled by a touchscreen interface - perfect for vending machine refurbishments and developing telemetry systems.
