1Do not run the communications lines in the same conduit as AC power. Correct connections may require the use of an Ethernet cross-over cable.

2Use Shielded twisted-pair, Category 5 (STP CAT5) Ethernet cable.

3Use Switch rather than Hub to maximize performance.

Figure 2-16 Ethernet Communications Option Connections

Figure 2-16 and Table 2-6shows how to connect a UDC to a MDI Compliant Hub or Switch utilizing a straight-through cable or for connecting a UDC to a PC utilizing a crossover cable.
