Jan,
Sorry it has taken me so long to get back to you on this, I had a
lightening hit and it took out my RS-232 to 1-Wire interface and didn't
have a spare.
With the DS2450 connected straight to the interface, it still comes up
with strange voltages after unplugging the DS2450 from the 1-Wire
network and plugging it back in.
Here are the values before:
owread /uncached/20.078914000000/volt.ALL;echo
4.61507, 4.63577, 4.65366, 2.37816
and after:
owread /uncached/20.078914000000/volt.ALL;echo
0, 0, 0, 4.78007
