Jan, I have done the update, but if the line that has the DS2450 drops offline and then comes back online I still get values that don't make sense. /usr/local/bin/owserver version: 3.2p1 libow version: 3.2p1 Values from the DS2450 before taking the line off line: 4.25 2.25 4.46 4.52 Values from the DS2450 after putting the line back on line. 0.00 4.44 0.00 0.00 I am using the ow C API to read all of my Dallas 1-Wire devices. I do a OW_init("/dev/cuao0"). I then go in to a loop and use OW_get to read each device. I use the following line to read the voltages: OW_get( "/uncached/1F.49D100000000/main/20.EDCD00000000/volt.all", &buf, &s ); -- Michael D Hughes
