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, 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).
