Frequently Asked Questions
Question 12: HOW DO I EXTEND THE RS-232 LINE DISTANCE?
Answer: The RS-232 data line has a distance limitation of fifty (50) feet (about 15 m), while the RS-485/RS-422 can go up to 4000 feet (1200 m). It is a common practice to use the converters to extend the RS-232 data line. To protect your RS-232 devices from surge voltages while extending the RS-232 distance, we would recommend the REP-232-3P - an optically isolated RS-232 data repeater (extender) (TX, RX, and GND), which works in pairs to extend the full-duplex RS-232 distance up to 4000 feet (1.2 km). This product features opto-isolation circuitry, which effectively protect your RS-232 devices from transient surges, ground loop, and remote lightning.
