I understand the concept of making the converter for a single radio using the MAX 232 chip. My thing is I have 5 radios I would like to control from the pc (and have plenty of serial ports).Is there a way I can utilize maybe 1 chip to do the conversion for the five radios.(maybe the MAX 235) as I see it has more TTL/CMOS inputs and RS-232 outputs.I will put up a very simple block diagram of what I would like and maybe someone can give me the proper information and point me in the right direction.

Would what I have drawn up work and would I need to modify the power supply any as at times there could be 3 radios on at 1 time.


Thanks

Tim
