Proove packet structure (32 bits): | ||
HHHH HHHH HHHH HHHH HHHH HHHH HHGO CCEE | ||
H = The first 26 bits are transmitter unique codes, and it is this code that the reciever “learns” to recognize. | ||
G = Group code. Set to 0 for on, 1 for off. | ||
O = On/Off bit. Set to 0 for on, 1 for off. | ||
C = Channel bits. | ||
E = Unit bits. Device to be turned on or off. Unit #1 = 00, #2 = 01, #3 = 10. | ||
|
||
Physical layer. | ||
Every bit in the packets structure is sent as two physical bits. | ||
Where the second bit is the inverse of the first, i.e. 0 -> 01 and 1 -> 10. | ||
Example: 10101110 is sent as 1001100110101001 | ||
The sent packet length is thus 64 bits. | ||
A message is made up by a Sync bit followed by the Packet bits and ended by a Pause bit. | ||
Every message is repeated four times. | ||
