Data Connect DCE 2178HEE
Industrial Ethernet Extender

The Data Connect DCE 2178HEE is a point-to-point Industrial 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 Data Connect 2178HEE functions 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 Data Connect 2178HEE 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 Data Connect 2178HEE is used in pairs to extend Ethernet connectivity over existing voice grade copper wire
