Details
The TTL33-232-1 is a compact, rugged, industrial-grade, port-powered RS232 to 3.3V TTL converter, which can be used to convert RS232 to 3.3V TTL / CMOS compatible levels and vice versa. This industrial RS232 to 3.3V TTL converter operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and features 600W surge protection and 15kV ESD static protection. The unit is efficiently powered from the RS232 data line, and the full-duplex RS232 to full-duplex TTL conversion eliminates the need of auto-turnaround feature. This RS232 to TTL 3.3V converter also 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 for both commercial and industrial applications.
CommFront's products quality is ensured by our 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.
