I think I tried same query with DDG some days ago and I didn't get that, it looks good "Maximum RS232 voltage range of the IC can receive is –25V to +25V" so I don't brake it easily...it seems that it only need power of 3.3V, so it should look almost ready solution. Although RS232C port should be male not female. Anyway thanks.
