The D502 is an easy to configure Ethernet-to-RS485/RS422 gateway. It provides up to two RS485/RS422 interfaces (SER0 / SER1) as well as up to two 10/100 Mb/s Ethernet interfaces (ETH0 / ETH1). The Ethernet connectors comply with IEC 61076-2-101 (D-coded; female).
The Ethernet interfaces comply with IEEE 802.3 supporting 10BASE-T or 100BASE-TX, full duplex mode, auto-negotiation and auto MDI-X. Furthermore, the internal logic supports the "Ethernet on traction vehicles" standard IEC 61375-3-4.
The optional second Ethernet interface ETH1 is intended to be used as a redundant line or as a separate channel for remote diagnostic and maintenance purposes.
duagon's gateways are available in two variants – as platform to build a customer-specific application or as gateway with a standard configurable gateway application. The platform variant is accompanied by a development library that enables fast and efficient design of customer-specific applications.
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).
The D502 is designed for the harsh traction environment and conforms to the EN 50155, EN 50121, and IEC 61373 standards in general, but particularly by:
- -40 °C to +70 °C ambient temperature range
- Interruption voltage supply class S2
- Coating against humidity
- Enhanced EMI and vibration robustness
- Proprietary high-performance Ethernet communication stack; optimised for cyclic process data.
- Support for most common real-time Ethernet protocols including IPTCom, EtherNet/IP – CIP, TRDP and TRDP with SDTv2.
- Optional redundant Ethernet interface.
- duagon web server for remote diagnostics and firmware updates; possibility to implement customer-specific web pages.
- Standard C development library to design customer-specific gateway application.
