MDB: Multi-Drop Bus Payment Integration
The Multi-Drop Bus (MDB) is the industry-standard protocol engineered to simplify device communication for vending, kiosks, and access control solutions. MDB streamlines your architecture by transmitting both power and data over a single, robust serial connection.
Benefits of Using MDB
MDB offers a range of benefits that enhance the performance and reliability of your self-service solutions.
Plug and Play
Requires minimal configuration to connect into MDB and the payment device. Get up and running fast.
Configurable
Add additional settings such as timeouts, logging levels, and more to match your deployment needs.
Webhooks
Ability to specify external webhooks to alert systems of connectivity problems in real-time.
Affordably Priced
Available at an annual subscription with competitive pricing that scales with your business.
MDB Key Features
A robust protocol designed to streamline device communication, offering features that enhance reliability, reduce costs, and ensure interoperability.
Multi-Device Communication
Allows up to 32 devices to connect and communicate on a single bus, significantly reducing wiring complexity across your entire deployment.
Power & Data Combined
Transmits both power and data over the same cable infrastructure, using a 24V DC power supply with a 115.2 kbps data rate on a 5-wire connection.
Master-Slave Architecture
A centralized master controller initiates all communications by polling the slave devices, which only respond when addressed for reliable orchestration.
Cost-Effective
Simplifies wiring, leading to lower material, installation, and labor costs. One bus replaces complex multi-cable setups.
Reliable Performance
Designed for robust performance in harsh environments, featuring error detection mechanisms like CRC checksums and timeout features.
Standard Protocol
The MDB/ICP standard is widely adopted in vending and access control industries, ensuring interoperability between different manufacturers' devices.
Addressing System
Each device has a unique address for targeted communication, enabling precise control over every peripheral on the bus.
Noise Immunity
Differential signaling provides excellent noise rejection capabilities, ensuring clean data transmission even in electrically noisy environments.
Common Applications for MDB
MDB powers reliable communication across a wide range of self-service and unattended environments.
