X6 RS232 / 485 Connections

RS232

A null modem cable (also called a modem eliminator cable) must be used to connect the control and the computer COM port. This will ensure that the transmit and receive lines are properly connected. Either a 9 pin or a 25 pin connector can be used at the computer, Figure 3-21. Maximum recommended length for RS232 cable is 3 ft. (1 meter).
