CIM Port

The CIM ports require standard 8-pin modular jacks (RJ-45) consisting of 2 balanced signal pairs on a
Category 5 Universal Twisted Pair (UTP) crossover cable. The twisted pairs are arranged as: 1,2: 3,6;
4,5; 7,8. Each tied pair is connected to a 75 ohm resistor. The following table lists the signal for each pin.
