RS-232 Maximum Cable Length
The maximum cable length for RS-232 is 50ft, but in practice, it depends on baud rate, cable specific capacitance, and ambient noise. The table below contains some rules-of-thumb from experiments done by Texas Instruments years ago.
| Baud rate | Maximum range / cable length |
|---|---|
| 19200 | 50 ft |
| 9600 | 500 ft |
| 4800 | 1000 ft |
