H2-ECOM100 Network Cabling
The H2-ECOM100 module supports 10/100BaseT standard cabling consisting of copper wire
twisted pairs.
The cable used to connect a PLC (or PC) to an Ethernet switch is called a patch (straight-
through) cable. The cable used to connect together two PLCs, a PC and a PLC, or two
switches is a crossover cable. We recommend that you purchase cables pre-assembled with
connectors for convenient and reliable networking.
NOTE:
The above diagram illustrates the standard wire positions in the RJ45 connector. We recommend
all ECOM 10/100BaseT cables to be Category 5, UTP cable.
