Chapter: 2. Operation
TXT/BIN: A new le will be created every hour. The lename format is YYMMDDHH.[ext], where YY is
current year, MM – current month, DD – current date and HH – current hour. The extension depends on the
recordings type. In case of text recordings, the extension is “txt”, in case of binary format – “bin”. If the le,
corresponding to the current date/time already exists, the new history will be appended; otherwise the new
le will be created.
The GDS logging function, logs all changes in results or settings when the value changes. The les will
be very small if the vessel sails without external inputs. However assuming all parameters are changed for
every ping (impossible) and GPS is also logged, data in .txt format will give a minimum of 177 days data
per GB disk space. In reality a GB can easily give a year of data.
The standard disk is 128 MB giving a minimum of 20 days, in practice 2 months. The system can be made
to loop or log until the disk is full. The amount of disk left is shown on the status screen. Bin les store the
same data in binary format and will be smaller. New les are started every hour, and named by the date and
time. Each new le will have the full settings in the rst lines.
Simulator
The GDS101 contains a built in simulator to test the screen and various interface signals. The simulator may
be switched on and off on screen 9. When the simulator is operating, “DEMO” is ashing at the bottom of
the screen. See “Fig. 2.10. Screen 9, System status screen.” on page 21.
Status Screen
The status screen, screen 9 shows a list of various system parameters useful for documenting system
setup and operating status. The contents of this screen will be valuable information in situations where
manufacturer support is required. See “Fig. 2.10. Screen 9, System status screen.” on page 21.
Oscilloscope Screen
The oscilloscope screen, screen 10 is useful when monitoring transceiver performance. The oscillogram
shows the signal returned from the transceiver plotted against time and will enable service personnel to
evaluate system performance and facilitate any troubleshooting. See “Fig. 2.11. Screen 10, Oscilloscope
screen.” on page 22.
Nonvolatile Flash Parameter Memory
The system contains internal ash memory to maintain installation and user parameters like language and
unit of measurement selection, contrast and backlight settings, etc. These parameters are automatically
restored on power up. If the user parameters have never been set, default values are used.
Options
Repeaters/Slaves
Graphic display or digital depth slave repeaters may be connected to the system. Along with the graphic
display repeaters, there may also be installed a remote keyboard.
Remote Sounding Control
This option lets the GDS101 being controlled remotely in synchronized (edge), burst (level) or single ping
modes. If installed, this option is accessible on screen 3. See “Fig. 2.4. Screen 3, 3rd Operation screen.” on
page 15. (Note: Non Wheelmark model).
