Appendix C – RS-232 Communication
Communication between the SmartSensor and PC can be established using the RS-232
DTE specifications, along with the use of a Null Modem cable and the standard 9-pin
“D” male connector. Please use the following guidelines for connecting the SmartSensor
cable to the serial connection on a PC or modem when not using a Click! 200.
NOTE: The RS-232 pin outs remain the same on the SmartSensor cable regardless of
connecting to a PC or a modem. If connecting to a PC, a null modem cable is required
(see Figure 17). If connecting to a modem or other DCE device then a straight through
serial cable is used (see Figure 18).
