Naw - RS-485 is easiest and cheapest way to go. You you need is the converters and a reel of twisted pair. I've set them up quickly and cheaply at an industrial sensing company, located on one of those huge New England mill buildings. They have some built-in isolation.
I've used the B&B Electronics with good results.

I've used it in the past for controlling satellite modems several thousand feet away using multimode fiber. Jumpers are available premade from Fiber Instrument Sales in whatever size you like.

Bob; Why would that baud rate be a limitation? Could you get a couple RS232 to Fiber Optic modems or at least some copper RS232 line extenders (Try Black Box) and make it work?

Does anyone have a PCR-1000 ICOM remote controlled receiver?
How long can the serial port cable be? I heard it was operating at something like 112,000 baud and could not be run the 200 feet to our roof. This makes it a deal breaker.
Is there a better all mode all band remote controlled system for roof mount to avoid long cable runs for satellite receiption across all bands..?
