Crossover cables

Normal network cables are designed to connect the CAB to a network switch only. You cannot use this type of cable to connect a CAB directly to a NION CM-1 card. For that you need a crossover cable.

A crossover cable is terminated the same way as a normal cable, except that the TX and RX pins are swapped at one end to allow the transmit pair of one device to connect to the receive pair of the other.
