5.3 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 or ports on the module are 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 detects the cable type and uses the appropriate pins to send
and receive Ethernet signals.
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 134) for a diagram of how to
configure Ethernet cable.
