Setting up Visual Analog and running the data capture demo

1. Determine the modules COM port number
   1. Open the device manager, right click onto windows start menu symbol and select device manager

   2. Open ports and identify the port used by the module, the number is here marked with an X

   3. Click Add in the new opened window and insert the name "adcapture" in the Display Text.
      Click Browse... and select the file "adcapture.exe" from the downloaded demo.
      Into Arguments insert "COMX,115200 1024 c:\temp\capture.txt 1", where the X in COMX
      is a placeholder for your comport number.

      To finish the setup press OK.

      Parameter description:
      COM14 - COM port which is used for the connection.
      115200 - Baud rate which is used for the connection.
      1024 - Amount of K samples to read, minimum 64 and maximum is 1024.
      c:\temp\capture.txt - File name and path which specifies where to storage the data.
      1 - Command to adjust for the modules gain, possible values are:
                 1 for a gain of 1, 2 for a gain of 2, 4 for a gain of 4 and 8 for a gain of 8
      

   Launch adcapture

   1. 
      

   2. Befor running the demo, fill in Visual Analog, fill into the Pattern Loader the ADC sampling rate of your module:
      TEI0015 - 2 MHzMHz  / Resolution - 18 bit
      TEI0016A - 0.5 MHzMHz  / Resolution - 16 bit
      TEI0016A - 1 MHzMHz  / Resolution - 16 bit
      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.

3. Launch adcapture

1. 1. To run the demo, select the above inserted tool by selecting Tools → adcapture, a new window opens
      

   2. The window shows the activity of the tool "adcapture", the picture below shows

its state

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.
