Hi, system Libranet 2.8.1 (kernel 2.4.22, libcomedi0 0.7.21.-3, libcomedi-dev 0.7.21-3, comedi-modules 0.7.67-3, ktimetrace 0.2.36-4). Setup AIN0 = + 2.00V, AIN1 = -2.00V. When I run ktimetrace, ch0 starts as the top trace, ch1 is the bottom trace. The traces evetually flip back and forth and the data saved to file does the same. I ran comedilib demo program cmd and if I read more than 2048 samples (for ex cmd -r 2 -n 2 -N 2049 -F 1000 > test.txt) I get a series of zeros as the early data points with the later ones being correct. DAQ is National Instruments DAQ-Card 6062E. Any input would be more than welcome. tia -- Luc Lefebvre In the beginner's mind there are many possibilities, in the expert's mind there are few. <Shunryu Suzuki> Key fingerprint = D2E5 5E35 B910 6F4E 0242 EC63 0FD9 96D0 C7F4 784E
