When the SCAMP Control Dialog (SCD) is begun it automatically establishes communication with the SCAMP and uploads any profile data that may be available. Data are uploaded profile-by-profile and are stored on the disk at the current directory location. Profiles are named with the following format:
ddmmmyyyy hhmmss.raw
ddmmmyyyy hhmmss.txt
Two files are recorded for each uploaded profile. The *.raw file contains SCAMP parameters and raw data in binary format. The *.txt file contains SCAMP parameters and other info in text format, but does not contain any measured data.
The file name is constructed from SCAMP’s internal time. The time used is the time that one of SCAMP’s start conditions became true thereby starting the profile. For example if SCAMP was programmed with a 60 second delay and a start depth of 10 meters, and it either reached 10 meters or 60 seconds elapsed on the 15th of January 2004 at 16:24:03 SCAMP internal time, then the files recorded would be named:
15JAN2004 162403.raw
15JAN2004 162403.txt
These files would appear in the current directory, usually the directory that contains the SCAMP Control Dialog. (Note that SCAMP internal time is set to the host computer’s time each time the SCAMP Control Dialog begins operation.)
If SCAMP has acquired multiple profiles since the last data uploading, then all profiles are loaded in sequence and a pair of files are recorded for each.
The *.txt file is text format and can be viewed with any text reader such as Notepad. The *.raw file is binary format and can be accessed only with special software supplied by PME. Two methods are supplied: one for Matlab and a ENGUNIT.EXE program that converts raw data into ASCII files of calibrated engineering units. C-language source for ENGUNIT is available from PME for users who want to create their own data interface.
