Listed are the port, the modules name and its USB ID
During notebook initialization, ports are scanned

• 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

After a trigger event, the one mega sample of data is stored until your retrigger. So processing the data can be done for each chunk individually or the whole one mega sample.

Information to convert Convert the RAW ADC data into standard integer values.
