i thought so too, i checked the output of the computer hooked directly up to the relay board with a scope and it checked out at -12 and when i sent the packets it went up to +12 +-, but when i check the out put of the radio it only goes down to -5 volts and up to +5 volts when info is sent.... i figured if i sent packets through the computer everything would work out the way i wanted it to.... not logical? it has me stumped.... :)

My two devices are already hooked up to the computer and im using them for other things, what it im doing is hooking up a 900mhz xbee radio to the computer and controling a R8x Pro relay contoller with my other computer from a base station.... would be nice if i could hook up the radio straight to the relay contoller but RS232 voltage levels wont work togehter... just figured that if i could RX over one com port and TX over the other then everything would work great... but it seems that its harder than i thought.... :(
