The first 2 pulses are the header and the last 2 pulses are the footer. These are meant to identify the pulses as genuine. We don't use them for further processing. The next step is to transform this output into 36 groups of 4 pulses (and thereby dropping the header and footer pulses).

If we now look at carefully at these groups you can distinguish two types of groups:

1. 294 1176 294 294
2. 294 294 294 1176

So the first group is defined by a high 2nd and the second group has a high 4th pulse. So we take either of these two pulses to define a 0 or a 1. In this case we say a high 2nd pulse means a 1 and a low 2nd pulse means a 0. We then get the following output:

001010111011001001000100100110010111

Each (group) of numbers has a specific meaning:

• ID: 0 till 25
• All: 26
• state: 27
• Unit: 28 till 31
• unknown: 32 till 35

00101011101100100100010010 0 1 1001 0111

• The ID is defined as a binary number
• The All special pulse to identify the code was meant for a dimmer
• The State defines whether a devices needs to be turned On or Off
• The Unit is also defined as a binary number
• The unknown bits are missing in the opened state

So this code represents:

• ID: 11454738
• All: Single
• State: Opened
• Unit: 9
