#95800 - Pulse position Responding to: ???'s previous message |
From what I recall, X10 uses pulse position encoding - depending where the pulse (I mean burst of carrier) occurs in relation to the zero crossing of the mains voltage. I think the data rate was 1 bit per cycle. Also, another consideration if you're using 3phase is leakage of the carrier from one phase to another. Or just do as the Zellweger system does - don't bother with trying to synchronise to the mains! |
