Protocol and Programs for Laserliner SoundTest-Master device, bought ~2012 from Conrad (rev 0111)
It has a serial interface (led output) 2400 baud, 8, N, 1
It has "binary" output. Each "sentence" consists of 18 bytes, the first one is >127 (sync).
My current guesswork amounts to this:
| idx | value | remark |
|---|---|---|
| 0 | Start and Status | >127 |
| 1 | Over/Under range | |
| 2 | db 100 | |
| 3 | db 10 | |
| 4 | db 1 | |
| 5 | db 0.1 | |
| 6 | ?? | 0 |
| 7 | ?? | 0 |
| 8 | ?? | 0 |
| 9 | ?? | 1 |
| 10 | ?? | 0 |
| 11 | ?? | 1 |
