MVB Interface with Flexible Configuration
The D113 is a multipurpose MVB interface card designed in a PC/104 form factor. It provides full support for the Multifunction Vehicle Bus (MVB) and complies with the TCN standard IEC 61375-3-1 up to class 4, making it suitable for a wide range of railway control and communication applications. The D113 is available in two functional configurations: process data only or process and message data; each optionally extendable with a bus administrator.
MVB Controller
At its core, the D113 integrates duagon's MVB Controller (DMC) implemented in an FPGA, supporting up to 4096 process data ports. The process and message data configuration includes a CPU that runs the message data stack directly on the module, offloading communication tasks from the host and reducing host CPU load compared to ASIC-based MVB interface solutions. In process data only configuration, the MVB interface is controlled directly by the host.
Easy Integration into Host System
To simplify system integration, the D113 offers a standardized PC/104 host interface and a wide range of hardware options, including MVB physical layer variants (ESD+, EMD), connector types, and host interface configurations. This allows the D113 to be tailored to specific system requirements. Together with duagon's multi-card host driver kit, including optimized process data drivers and application examples, the D113 can be quickly and efficiently integrated into new or existing host systems.
For Rolling Stock Environments
Designed for harsh rolling stock environments, the D113 meets railway requirements for temperature, humidity, vibration, and EMC. It operates reliably from –40 °C to +85 °C, features conformal coating against humidity, and provides enhanced EMI and vibration robustness in accordance with EN 50155, EN 50121, and EN 61373.
