B&B Elinx EIRM Series Managed Ethernet Copper Extenders - Extends Ethernet up to 1900m

Industrial grade, 10/100 Ports, Managed DIN Rail Ethernet Extebder with PoE port


B&B Electronics’ Industrial Hardened EIRM-EXTEND is a point-to-point Managed Ethernet Extender designed to operate in harsh environments that efficiently extends 10/100 Ethernet circuits to over 300meters (984feet) at 50Mbps using existing cross-over pair copper wire.

The EIRM-EXTEND Managed Ethernet Extender operates at temperatures ranging from -40°C to 75°C (-40°F to 167°F) and is tested for functional operation @ -40°C to 85°C (-40°F to 185°F). The EIRM-EXTEND will allow Ethernet connectivity in existing facilities without pulling extra cable. This is the perfect solution to Ethernet on the factory -floor where systems have been upgraded from slower serial communications to Ethernet networking. Installation is easy with a single switch setting; one end is set for local and the other remote.

The EIRM-EXTEND is used in pairs to extend Ethernet connectivity over existing voice grade copper wire. The EIRM-EXTEND provides LED display for Power, VDSL speed and Ethernet connection status. The EIRM-EXTEND also provides several advanced functions such as System, SNMP, F/W upgrade, and Load Default setting through the Web based browser to enhance total networking performance.
