hi
i do need your help to find any kind of device to convert NMEA sentences to RS422 port or RS232 using the microcontroller if possible.
thanks guys

Correct me if I'm wrong but i believe NEMA is an soft protcol while RS422 and RS232 is electrical (physical) protocols.
What device is produceing these NEMA sentences?
 

Yes NMEA 0183 is a soft protocol and GPS's and other devicec usualy uses rs232 (4800-baud ) to send the data so most probably you just can attache your device to your cpu or computers serial port. U might need som voltage adjuster for the signaling like a max232 but thats almost never needed. If its a USB gps it probably install itself as a usb com port on the system.

However there ar some newer standard NMEA 2000 that I dont know that much about where the electrical buss is included in the standard as wel, its still serial. But I dont think that form of NMEA is used that much for noncomersial boating, if at all.

regards Me
