use a RS232 to RS485 adapter and sort your S/W to suit.

Subject: serial port dilemma - design advise requested


I have a PIC device that connects to my PC via serial port for constant
communication.

I would like to have over 10 PIC devices connected to my PC somehow for
communication.

However, i would not like to buy some sort of expensive multi serial port
card for it.

What sorts of things can i do to over come this problem? Potentially i would
like to use over 10 of these PIC devices at once.

Thanks all!
