As the level and phase issues have been clarified, I think you can go ahead and connect this GPS receiver to MAX232 as per your circuit (I don't think 22kΩ is necessary) ..

Tested OK. The Module is outputting 6 sentences each second .As I have placed the unit now in indoors the data seems nonsense, some series of zeros . preceeded by NMEA headers.(Format is Ok)

Now I have to configure this module to out only lattitude and longitude as for now. For that i have to input sentences(SET) into the unit.

Any Words of caution?


also next stage Place this unit outdoors and bring this data some 5 meters indoors.

Thanks a lot for the help

With regards

5m of shielded cable shouldn't be a problem ..
You can send data and power through the same cable ..
