Tech Lowdown
What is the maximum distance I can run RS-232?
The RS-232C standard specifies a maximum cable length of 50 feet or 2500 pF of capacitance. A typical off the shelf cable is capable of 9600 bps at 50 feet. However, data rate and performance decreases as cable length increases. As cable length increases so does capacitance and the maximum data rate is a direct function of the capacitance of the cable. It is recommended to use a shielded cable since this can help to reduce stray capacitance. If running distances over 50 feet, you should use the lowest capacitance shielded cable available. If you are terminating your own cable, connect the shield to chassis ground only at one end.
