Using Straight Through or Crossover Copper Wiring
To accommodate signals from end devices and network switching equipment, the
RUGGEDCOM RMC is equipped with an
X-Over
switch. This switch allows for the
proper connection regardless of the cable type configuration.
CAT-5 network cabling can be constructed in two possible configurations: Straight
through and crossover (X-over). Straight through cabling involves a pin-to-pin
connection, while crossover cabling matches the transmitting differential pair to the
receiving differential pair. The following summarizes the two possible configurations:

When connecting to end devices, the
X-Over
switch should be selected to reflect the
type of cabling used. Specifically, straight through should be selected when using
straight through cabling, and crossover should be selected when using crossover
cabling.
