6.2.2 Ethernet
Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
The Ethernet port on the module is Auto-Sensing. You can use either a standard
Ethernet straight-through cable or a crossover cable when connecting the
module to an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a PC.
The module will detect the cable type and use the appropriate pins to send and
receive Ethernet signals.
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, you must ensure
that the switch position and cable type agree.
Refer to Ethernet cable configuration (page 137) for a diagram of how to
configure Ethernet cable.
