Data Connect
2178MPEE Ethernet Extender

The Data Connect DCE/2178MPEE Industrial Grade Multi Port Ethernet Extender is a one 4-port 10/100Base-TX switch and one 2-wire Ethernet port used to extend Ethernet up to 300 meters (984ft) at 50 Mbps over two existing voice grade copper wires. A simple single switch allows for a choice between local or remote setting. Thus select local for side A of the circuit and select remote for side B of the circuit. The DCE/2178MPEE is fully managed via SNMP, Web Browser, and Telnet or console port and is designed to integrate 10/100Mbps networks into VDSL backbone. The DCE/2178MPEE supports advance features such as 802.1Q VLAN, MAC-based Trunking, IPMulticast IGMP Snooping, and Rapid Spanning Tree for Redundancy, QOS foe priority Queuing, and Port Mirroring. The DCE/2178MPEE functions at temperatures ranging from -40°C to 75°C (-40°F to 167°F) and tested for functional operation at -40°C to 85°C (-40°F to 185°F). The DCE/2178MPEE complies with NEMA TS1 & TS2 that meets with Environmental requirements for Traffic Control equipment and complies with IEC61000-6-1 EMC, a Generic Standard Immunity for the industrial environment.
