can`t you buy a transmitter and resever. then you have to make it all work and you need to send information to it and stuf and you need to collect it and under stand it all. I have had a project 1 time and we made a program in the PC end sending information on the com port (RS232) put that with a cable in a transmitter(buy a build packet) that send it to a resever(buy build packet) send it to a processor try to make some about it send it to the next processor that made it a fast DMX protocol and send it so a scanner and stuf circuit. And to get it all work is not that easy even if you buy a own build packet for a transmitter.
