Ethernet-to-MVB Gateway
The D503 is an easy to configure Ethernet-to-MVB gateway. It provides a line redundant MVB interface as well as up to two 10/100 Mbit Ethernet interfaces (ETH0/ETH1) on D-coded receptacles.
The flexible platform supports most train-borne real-time protocols connecting an IP-based end device with the MVB fieldbus e.g. to acquire diagnostic data.
The Ethernet interfaces comply with IEEE 802.3 supporting 10BASE-T or 100BASE-TX full duplex mode auto-negotiation and auto MDI-X.
Variety of Product Options
The optional second Ethernet interface ETH1 is intended to be used as a separate channel for instance for remote diagnostic and maintenance purposes.
The MVB interface complies with the TCN standard IEC 61375 and supports devices up to class 4. Optionally the device includes either process data only or also message data and may act as a bus administrator.
duagon gateways are available in two varieties: as a classic "gateway" with a standard configurable gateway application or as a "platform" to build a customer-specific application. For extended or very special requirements the platform variety is accompanied by a development library that enables fast and efficient design of specific applications either by duagon as a service or by the customer.
Extended Cybersecurity Long-Term Availability
duagon offers different cybersecurity packages to harden the D503. The available packages include features such as secure communication for remote access centralized user access management secure event logging and secure firmware updates.
Its System-on-a-Chip (SoC) design based on a PLD ensures future portability and long-term availability.
For Rolling Stock Environments
The D503 is designed for harsh rolling stock environment and complies with the EN 50155 EN 50121 and IEC 61373 standards: it withstands -40 °C to +70 °C ambient temperature complies with interruption voltage supply class S2 is coated against humidity and provides enhanced EMI and vibration robustness.
The gateway is integrated in a stainless-steel housing that can be mounted on a DIN rail or using M4 screws. The device can be powered directly from the vehicle battery or by Power over Ethernet (PoE).
