3.2.2 Ethernet Cable Specifications
The recommended Ethernet cable is category 5 or better. A category 5 cable has
four twisted pairs of wire that are color-coded and cannot be swapped. The
module only uses two of the four pairs when running at 10 MBit or 100 MBit
speeds.
The Ethernet port on the module is Auto-Sensing. Use either a standard Ethernet
straight-through cable or a crossover cable when connecting the module to an
Ethernet hub, a 10/100/1000 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 but have eight conductors. Some
hubs have one input that can accept either a straight-through or crossover cable,
depending on switch position. In this case, ensure that the switch position and
cable type agree.
