Right. Looking at that diagram the caps appear to be correct but now im wondering about those chips. They are dual chips so can i use a single chip to give a single serial input to 2 PIC chips like in the diagram i uploaded before?

For modern-day RS232, I use the FTDI chips. The new 232R accepts the PIC outputs at whatever voltage it's running, regardless of the polarity it's running at (you don't need voltage inverters or level shifters, be it software uart or hardware). It takes very few components to get it to the PC, and, best of all, it's a USB chip so it'll work with any modern PC.

That sounds good. I am looking to move to USB eventually. The only problem i have is that each device would require a USB port. I was thinking about a distribution box though. Something that connects by USB to the PC but uses serial to connect to the lights
