Caution EIA/TIA-232 is often used at greater distances than specified in Table 2-2 on page 2-4. If you understand the electrical problems that can arise and can compensate for them, you might still obtain good results; however, we recommend that you keep your cable runs within the standard-defined distances.

Table 2-3shows the standard relationship between signal rate and maximum distance for EIA/TIA-449, V.35, and X.21 signals.
