RS–232 PC Connections

A null modem connection must be made between the LinStep+ 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 3-8. Maximum recommended length for RS232 cable is 6 ft. (1.8 meter).
