Data Capture/Playback Utility
ISDEMO has the ability to write the data it receives from the
tracker to a file. To utilize this feature you must first specify
the name and location of the output file. To start data
collection, select Record. Data can be Saved as is, or in an
ASCII or Binary Flat File. When the Flat File option is
selected, only tracker data is saved, one line per update cycle.
To import data to Excel or Matlab the output format must be
set to ASCII or the ASCII Flat File option must be used.
Previously recorded data can be displayed through ISDEMO
by selecting Play. Playback option will only work on files
saved with the Save as is option.
Send Command String Allows single line commands to be sent to the tracker. This
tool is provided to allow control over the tracker parameters
not supported in the ISDEMO menus and dialogs or on the
LCD button panel. For instance, this function can be used for
test and debug purposes. Type in the command and press
Enter or Return. The <CR LF> pair is automatically added to
the end of the line before it is written to the serial port. See
Section 4—Interface Communications Protocol for the
complete list of all available commands.
