The CVT-232B-3 is a compact, rugged, industrial-grade, port-powered, 7-wire RS-232 Isolator. This 7-wire RS-232 isolator optically isolates seven (7) RS-232 lines (TX, RX, RTS, CTS, DTR, DSR and GND), which effectively protects your RS-232 devices from ground loops, noise problems, transient surges, remote lightning and spikes. The unit operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and features 600W surge protection and 15kV ESD static protection. This 7-wire RS-232 opto-isolator is efficiently powered from the RS232 data line, and it comes with the auto-sensing and self-adjusting features, which automatically adjust baud rate, parity, stop bit and other COM port parameters to the devices that it is connected to. Therefore, it requires no external power, manual settings or software drivers, making the unit a highly reliable and truly plug-and-play device.

CommFront's products quality is ensured by its ISO-9001 quality control system (Cert No. SG12/04213, strictly certified by SGS), and we back our high-quality products with a 5-year replacement warranty and a 30-day risk-free money-back guarantee.
