Applications

The DIN-rail mountable 500NMD02 is a managed plug-and-play Layer 2 switch offering

– 4 Fast Ethernet auto-negotiating RJ45 ports with automatic MDI/X (automatic cross detection and correction)

– Two 2-wire SHDSL ports for dedicated copper cabling

– 1 RS-232/ RS-485 interface and 1 RS-232 interface dcs-sis.com for serial protocol tunneling

The switch provides redundant topology via Spanning Tree Protocol (STP/ RSTP/ MSTP). It supports VLAN framing and serial data tunnelling.

Ethernet can be distributed within the station via the switch’s four RJ45 ports.

The SHDSL port can be used for interstation interconnections up to a maximum distance of 25 km (0.8 mm diameter copper cable).

The SHDSL interface connects to any EDS500 SHDSL-compatible device, including the 560NMS24 and 560NMS34. as well as any EFM-based SHDSL device.
