6 Ethernet Cable Specifications
ProSoft recommends using using a category 5 (or better) Ethernet cable with the PLX35-
NB2. A category 5 cable has four twisted pairs of wire that are color-coded and cannot
be swapped. The gateway only uses two of the four pairs when running at 10 MBit or
100 MBit speeds.
The Ethernet port on the gateway automatically detects the network speed and cable
type and use the appropriate pins to send and receive Ethernet signals. Use either a
standard Ethernet straight-through cable or a crossover cable when connecting the
gateway to an Ethernet hub, a 10/100/1000 Base-T Ethernet switch, or directly to a PC.
