Description
AN-RS-232-TTL converter provides low cost solution for converting the RS-232 serial com port generated signals to CMS/TTL level signals for prototype or testing low level microprocessor or microcontroller based systems.
The RS-232C side can be connected directly to PC DB9 serial port connector. That makes a AN-RS-232-TTL converter as a great solution for connecting external CMOS/TTL equipment, being prototyped on your PC or laptop computer. Converter is powered by host computer systems sygnal lines. This eliminates the need for an additional external power supply making the adapter as ideal choice for portable use.
