The RPT-232-3 is an industrial grade (wide temperature range with surge & static protection) port-powered 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 1.8 miles (3 km). This product features opto-isolation circuitry, which effectively protect your RS-232 devices from ground loops, transient surges and spikes. The unit is powered from the RS-232 data line, and therefore, no external power or RTS, DTR is required.
