TECHNICAL INFORMATION FOR THE PROFESSIONAL
X-10 transmissions are synchronised to the zero-crossing point of the AC power line. Power line interfaces provide 50Hz square wave with a max. delay of 100 µsec. from the zero crossing point to the AC power line. The maximum delay between signal envelope input and 120 KHz output bursts is 50 µsec.
A binary 1 is represented by a 1 millisecond burst of 120 KHz, at the zero crossing point and a binary 0 by the absence of 120 KHz. These 1 millisecond bursts are transmitted three times to coincide with the zero crossing points of all three phases in a three phase distribution system.
