Figure 2-11 Ethernet Communications Option Connections
Figure 2-11 and Table 2-6 shows 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.

Table 2-7 shows how to connect a UDC directly to a PC utilizing a straight-through cable
(wiring the UDC cable this way makes the necessary cross-over connections)
