Network Cabling
Of the two types of EBC modules available, one supports the 10/100BaseT standard and the
other one supports the 10BaseFL standard. The 10/100BaseT standard uses twisted pairs of
copper wire conductors and the 10BaseFL standard is used with fiber optic cabling.

8-pin RJ45 Connector
(8P8C)
10/100BaseT
The 10BaseT and 100BaseT EBCs have an eight-pin modular jack that accepts RJ45
connectors. UTP Category 5 (CAT5) cable is highly recommended for use with all
Ethernet 10/100BaseT connections. For convenient and reliable networking, purchase
commercially manufactured cables which have the connectors already installed.
To connect an EBC, or a PC, to a hub or repeater, use a patch cable (sometimes called a
straight-through cable). The cable used to connect a PC directly to an EBC or to connect
two hubs is referred to as a crossover cable.
