Black Box High-Speed Ethernet Extender Unit - short-haul modem

The High-Speed Ethernet Extender is designed to easily interconnect a central LAN to remote devices or remote networks located at lot farther away. The High-Speed Ethernet Extender Unit can be configured as either a local or remote unit simply by flipping a switch. It has an RJ-45 port for the interconnection and a shielded RJ-45 port for a LAN link. Because the LAN port has an automatic MDI-X feature, you can connect it to a hub or PC with a straight-through or crossover cable.
