This connector is used for Ethernet communications from the Acc-2P to a PC, and it is provided when Acc-2P
Option 1B is ordered. The appropriate Category 5 10/100-Base T network cable that mates to this connector can
be readily purchased from any local computer store. The type of network cable to purchase depends on the
configuration to the host PC.
When making a direct connection to a Host communication Ethernet card in a PC a cat 5 networking crossover
cable must be used. A standard cat 5 straight through networking cable cannot be used in this scenario. When
using a connection to a network hub or switch, the standard cat 5 straight through networking cable must be used,
and not a crossover cable.
