This connector is used for Ethernet communications from the UMAC to a PC. The appropriate Category
5 10/100-Base T network cable that mates to this connector can be 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 Category 5
networking crossover cable must be used. A standard Category 5 straight through networking cable
cannot be used in this scenario. When using a connection to a network hub or switch, the standard
Category 5 straight through networking cable must be used, and not a crossover cable.
