Ethernet connection

The standard RJ-45 Ethernet socket is used to connect the unit directly to a PC or to a
network. To connect directly to a network hub or switch, use a straight-through network
cable. To connect directly to a PC, use a cross-over network cable. Consult with your local IT
personnel for the specific type of cable needed. The maximum cable length from node to node
is limited to 100 meters (300 feet).
