For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps) | Maximum RS-232 Cable Length (ft) |
19200 | 50 |
9600 | 500 |
4800 | 1000 |
2400 | 3000 |
