Unit and device id's

The old Rev devices use DIP switches: First six for ID and last 4 for units itself.

This protocol sends 50 pulses like this

It has no header and the last 2 pulses are the footer. These are meant to identify the pulses as genuine, and the protocol also has some bit checks to filter false positives. We don't use them for further processing. The next step is to transform this output into 12 groups of 4 pulses (and thereby dropping the footer pulses).

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

1. 256 768 256 768
2. 256 768 768 256

1. pulse at first and third place is translated to high = 1
2. pulse at first and fourth place is translated to low = 0

(C/D are really crossed)

Bit12 set = on
Bit11 set = Off

Each (group) of numbers has a specific meaning:

• ID: 0 till 5
• Device: 6 till 10
• OFF: 11 set only
• ON: 12 set only
