The following step should be taken in this mode:

  • Open a serial comport
  • For TEI0015 and TEI0016:   Send the command "1", "2", "4" or "8" for the ADC pre-amplification of 1, 2, 4, 8
    For TEI0023:                     Send the command "1", "2", "3", "4", "5", "6" or "7" for the ADC pre-amplification of 0.25, 0.5, 1, 2, 4, 8 and 16
  • Send the command "t" to trigger the consecutive measurement.
    (The module always measures 1 MSample of data into its SD-RAM)
  • Clear the PCs serial comport input buffer of the opened comport
  • Send the command "+" or "*"to the module, it then transmits 128 or 16384 Samples of ADC values
  • Read the amount of ADC values in one chunk of 128 or 16384 samples from the PCs serial input buffer
    (Otherwise there is a high possibility of a misalignment of nibbles)
  • Repeat the reading of chunks to a maximum of 1 mega sample
  • Close the comport
