                 TEI0023:    1 for a gain of 0.25, 2 for a gain of 0.5, 3 for a gain of 1, 4 for a gain of 2, 5 for a gain of 4, 6 for a gain of 8 and 7 for a gain of 16

    2. Befor running the demo, in Visual Analog, fill into the Pattern Loader the ADC sampling rate of your module:
      TEI0015 - 2 MHz  / Resolution - 18 bit
      TEI0016-0x-08-C8A - 0.5 MHz  / Resolution - 16 bit
      TEI0016-0x-08-C8B - 1 MHz  / Resolution - 16 bit
      TEI0023 - 2 MHz  / Resolution - 18 bit

      This sampling rate is only changed, when the demo has been run.

      It is often necessary to fill in the value two times before it is recognized.
      In dependency to the language settings, 0.5 MHz is sometimes not recognized,
      try instead of the separation point (0.5) a separation comma (0,5) or without the zero (.5 ,5)
      In the graph section, one can check the present sampling rate

    3. In addition, the ADC resolution needs to be adjusted also. In the Input Formatter Box, press onto
      the small Button, and adjust in the new appearing window the resolution.

Quick test with a terminal program

  1. Figure out the correct COM port number for the AnalogMAX DAQ1 board
    1. Open the device manager.
    2. Open ports and identify the port used by the AnalogMAX DAQ1 as visible in Figure 10.

  2. Open terminal and set the parameters (example use for putty).
    1. Set the connection type to Serial.
    2. Set the "Serial line" to your above found COM port.
    3. Set the "Speed" to 115200.
    4. Use "Open" to start the connection.
  3. Type following character for the appropriate usage.
    1. "?" to get the ID (AnalogMAX DAQ1 will return "1", DAQ2 will return "2")
    2. "t" to trigger ADC capture into the memory - 1M samples.
    3. "." to get one ADC sample.
    4. "+" to get 128 samples.
    5. "*" to get 16*1024 samples.
