I have got only a multimeter (with simple logic probe function for small f
signals), no oscilloscope here but if it is very important I can borrow one
(CCCP old one but...) !

normally = ds1821.exe is not active, pin 7 (9pin socket) is LOW (and VDD pin of
the adaptor is HIGH). When I launch exe there is no visible change on the logic
probe, even when I chagne 1w/thermostat modes. My probe is to slow to record
these changes!
Voltage is 5V DC.
