straight-through cable to connect the controller to a MDI Compliant Hub or Switch.
Alternatively, you may use a crossover cable to connect your controller directly to a PC,
which is useful for commissioning purposes. Use only Category 5 (STP CAT5) shielded
twisted-pair Ethernet cables. For strain relief, secure your Ethernet cable to the controller
with the tie wraps included in the kit using the holes in the bottom controller flange.

Figure 2-22 Ethernet Communications Option without Adaptor Board
If you would rather wire your UDC to your Ethernet connection without using the
Ethernet Adaptor Board, then Figure 2-22 and Table 2-8 show the connections for 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.
