Accessing the cDAQ-9136 command line
------------------------------------
  - An ssh program such as putty is needed

  - power-up the cDAQ-9136

  - Connect it to the PC you're using

  - launch NI MAX and find the cDAQ-9136 IP address

  - launch putty and enter the IP address, select the SSH bubble
    and click open (This can be saved and loaded using the saved sessions section
    allowing you to skip finding the IP address with NI Max in the future)

  - Login using the defaults. This is fine since the cDAQ-9136 isn't on the network
    and only those with physical access can access it
    default username: admin
    default password:
    (Note: Be careful. admin by default has superuser priviledges. This means
    you can do some damage if you delete something accidentally. This was a bad
    design choice and would be changed in the future if I had more time)


Updating the configuration
---------------------------
  - The configuration the reader program uses can be updated using the
    ConfigWriter program

  - Launch the program and follow the on-screen directions
      ConfigWriter
    (Note: The ConfigWriter program has no error checks. If you enter
    a value that doesn't make sense it will accept it. This should be updated
    in the future. Be sure that the expected values are between -10 <= x <= 10.
    Also be sure the the sampling rate doesn't exceed 1 MHz.)

  - Since the reader program runs on power-up it is using the old config. It will
    read the new config upon a power cycle. If you wish to reload the config
    with out power cycling use the command
      reader-daemon restart
    or...
      reader-daemon stop
      reader-daemon start


Using the "--quick" reader option
-----------------------------------
  - The "--quick" option uses non-configurable settings
    (sampling rate = 500kHz, sample time = 300 seconds,
    recording ID = RBW, start time is 2 minutes in the future)

  - It is important to stop the reader-daemon first to ensure the reader program
    is not running twice. Also do not reboot after starting with the "quick"
    option or else the old configuration will be loaded instead of the "quick"
    settings

  - Here is an example of using the "--quick" option
      reader-daemon stop
      reader --quick


Accessing the data
-----------------------
  - The output .wav files are stored at /home/admin/reader/output/

  - I suggest using an SFTP client to download the files and remove them

  - Make sure the cDAQ-9136 is powered-up and connected to the PC or the network

  - Obtain the IP address in a similar fashion to when you connected to the cDAQ-9136

  - Using Filezilla enter the IP address for Host and the default username
    and password for the Username and Password. Then click Quickconnect

  - The remote filesystem should be displayed under remote site,
    and your system under local site

  - Navigate to /home/admin/reader/output/

  - Navigate to where you want the files downloaded to on your PC under local site

  - Right click the files you want to download and select download

  - When you are done with the files remove them from the cDAQ-9136 by
    right-clicking and selecting delete (if you don't remove fairly often
    the HDD will fill up quickly. Wav files can be quite large.)
