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 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 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 152) for a diagram of how to

configure Ethernet cable.
