Waveman & X10

If you are referring to Marelco Waveman, I do not think they are X-10 compatible. I think they use a 24-bit code similar (maybe identical) to Intertechno and Elro while X-10 uses a 32-bit code based on the NEC IR protocol.

Hi Dave,

Thanks for the links. Do you have any further details on the X10 security codes? I'm making my own X10 RF receiver. Do you know of any difference in timing between the 315Mhz and the 433 MHz X10 signals?

Ta,

Neil.

Using the second illustration in the X-10 RF link...

Using the first illustration and its first byte 00110111, the second byte is

There's no difference in timing between the 310MHz used in N. America and the 433.92MHz used elsewhere. Most X-10 receivers tolerate wide variations in timing. I've tested them with ±20% variations. Some European receivers may have tighter bandwidth.

IIRC my BX24-AHT source code at...
