Twisted Pair Crossover / Straight-Through Connections
Whether you are using crossover or straight-through CAT5 twisted pair cabling, media
conversion modules will support both types of connections by one of the following
methods:
AutoCross:
McLIM TX/FX (-00), McLIM TP-TX/FX and McGigabit include AutoCross, a feature
which automatically selects between a crossover workstation or straight-through
connection depending on the connected device.
MDI-II/MDI-X Switch:
All McPIMs feature a 2-position switch, located at position S1 (see page 3 for location
on boards), for selecting a crossover workstation connection or straight-through
connection.
