AX-12 Interface to PC Serial RS232 and PIC Microcontroller
2007-06-27 09:16:00
Dear Friends;
I need information how to control AX-12 (TTL) from serial port of PC (RS232). What are the voltage levels required ? True RS232 from PC is is +12V = bit OFF and -12V = bit ON. Is the AX-12 +5V bit ON and 0V bit OFF ? Or inverted ? Does someone have a schematic of an interface ? I would also
like to see an snippet of BASIC code like PicBasic or BasicStamp.
Thanks for any help.

Hi, friend.Thank you for waiting.I believe you are talking about the RS232 level.As you are aware the RS232 level is an inversed signal(with level changed) of a general serial communication port(UART).
