Hi Chris,
Actually, just after I posted my message I got Amaseis to recognize the com port, which it was doing intermittently. Then I found an old posting of yours about using the data window to set the zero value, which worked! Turn out the zero value is 40,800, a value I never would have found randomly. The next issue is noise. I am using the lower gain channel on Larry's amplifier/filter board and have Amaseis set on a gain of 1 with a decimate factor of 1. I am getting electrical spikes at about a frequency of one Hz. Any ideas?

I have tried two separate computers running Windows XP and Windows ME, two different ports, serial and USB via an adapter and the results are identical. I get activity on Seismowin but I find that program obscure versus Amaseis, which I have used in the past.


Hi Chris,

       This sounds like an AmaSeis setup file problem or a wrong choice of device. Check the text?

       Regards,
