10/100BaseT
Network Cabling
ECOM Supports Two Standards
Two types of ECOMs are available. One type supports the 10/100BaseT cabling standard, and
the other supports the 10BaseFL connection standard. The 10/100BaseT standard uses twisted
pairs of copper wire conductors, and the 10BaseFL standard is for fiber optic cabling.

10/100BaseT Networks
The cable used to connect a PLC (or PC) to a hub or repeater is called a patch (straight-
through) cable. The cable used to connect together two PLCs, or a PC and a PLC or two hubs
is a crossover cable. We recommend that you purchase cables pre-assembled with connectors for
convenient and reliable networking.
The above diagrams illustrate the standard wire positions in the RJ45 connector. We recommend
all ECOM 10/100BaseT cables to be Category 5, UTP cable.
