Cable Length
The original RS-232 specification limits cable length to 15.25 metres (50ft) at a maximum data rate of 20,000 bps (bits per second, also sometimes, usually incorrectly, refered to as the Baud rate), but in practice the interface is used well outside of these limits.
Maximum Cable length depends on a number of factors, including how well the sender and receiver are implemented regarding rise times, and cable capacitance, inductance and screening. These are all difficult to quantify, but the primary factor is the data rate . As a rule of thumb doubling of data rate halves the recommended maximum length.
A rule of thumb for reasonable practice is as follows:-
Maximum Data Rate (bps) Maximum Length)
2,400 (2.4K) 120m (400ft)
4,800 (4.8K) 60m (200ft)
9,600 (9.6K) 30m (100ft)
19,200 (19.2K) 15m (50ft)
38,400 (38.4) 7.5m (25ft)
57,600 (57.6K) 5.0m (16ft)
115,200 (115.2K) 2.5m (8ft)
Cables exceeding 15 metres are susceptable to crosstalk (switching in one cable core effecting other cores in the cable) at any data rate. This is equally true in ribbon cables. Long cables should be constructed using individually screened cores, particularly on the RXD and TXD signals.
