7.5 Ethernet Port Connection

7.5.1 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 145) for a diagram of how to

configure Ethernet cable.
