Thank you very much, I am now able to talk to a dBmeter from Brüel & Kjær, via USB and Python. http://www.bksv.com/3156.asp Sample Code if anyone else needs to do this task (on the 2250 model): import win32com.client q = win32com.client.Dispatch("BK.BasicEnv.Application.RemoteAPI") Instrument = win32com.client.CastTo(q, 'I2250Instrument') Connect = win32com.client.CastTo(q, 'I2250Connect') Control = win32com.client.CastTo(q, 'I2250Control') instrumentNames=Connect.GetInstrumentNames() Connect.Connect (instrumentNames[0]) db=Control.ReadOutputInt16(instrumentNames[0], "LACF(SPL)") print "dBA value %.1f\n" % (db/100.0) q.Disconnect() Best regards Mikael __________________________________________________ Do You Yahoo!?
