1. INTRODUCTION
System Summary.
GDS101 is a navigation sounder with a large, high resolution graphic LCD. The echosounder graphics are
continuously shown on the LCD along with complete navigational details.

It is possible to connect an external printer to the operator unit. The sounder contains a 24 hour history
memory. That can be printed out. Depth, time and all available navigation data are stored continuously so
that the last 24 hours of information is always available.
All this information may also be printed on the external printer. All IMO requirements are met or exceeded.
Comprehensive interfaces are available including NMEA0183 inputs and outputs.
TRANSDUCERS.
GDS101 is prepared for connection of the following transducers: 38, 50 and 200 kHz. One or more of the
transducers may be connected at the same time, and the desired transducer may be selected from the operator panel.
OPERATOR PANEL.
The operator unit contains a graphic dot-matrix supertwist LCD display and a keyboard with fixed keys, softkeys and a rotating encoder. The function of each soft-key button depends on the active screen, and the buttons
are labelled on the lower rim of the LCD. The display is backlit, and contrast and backlight intensity may be
adjusted by the user. The echo-gram is normally displayed continuously on the LCD and stored in the 24 hour
history memory. An optional external printer is used if hard-copy documentation is required. The operator
unit is normally flush mounted. Power supply options are 115/230V AC or 24V DC. The power consumption
is appx. 70 Watts at 115/230V AC or 50 Watts at 24V DC.
DATA ENTRY.
Several screens may be selected to enter various settings and calibration parameters. Each screen has a
selection of soft-key buttons.
Screens 1 through 3 are primary operation screens with appropriate operator controls. Screens 4 through
10 are calibration set-up and system supervision screens.
The various screens will be described in detail later.
RECORDED DATA STORAGE.
The displayed echogram and other navigational data is continuously stored in the 24 hour history
memory.
A standard printer type Hewlett Packard may be connected for paper copy, Ask Skipper Electronics for
specification.
Since the printer is only required when hard copy documentation is absolutely necessary, the paper consumption is expected to be limited under normal conditions.
WARNING! False bottom echoes may occur when :
a: The bottom is out of range.
b: Extreme noise conditions are present.
c: Bottom signal may be lost for other reasons, like wakes, or aeration below transducer.
The bottom line shown on the GDS 101 screen is a synthetic signal, made by the sounder`s computer.

Example of parameter entry.
Let us say you want to enter a value of 800 m for the depth range.
Press the Depth Range button several times and observe the depth range sequencing through the standard
values 10, 50, 100, 500, 1000 m. Press till the range is 500 m. Then press the Range button again and
keep it pressed while you turn the encoder clockwise. Observe the depth range increase to 800 m, let go
of the encoder and release the depth range button. You could also have started from the standard value
1000 m and decreased to 800 m by turning the encoder counter-clockwise.
Buttons with less than 6 possible states or values can be operated without using the encoder at all.
OPERATION SCREENS
Each of the operation screens contains a graphic picture and a selection of up to 6 soft key buttons. The various screens are selected by keeping the “Menu” button pressed and rotating the encoder in either direction.
Turning the encoder clockwise cycle the screens in the sequence 1 to10, and counter clockwise rotation cycles
the screens in the sequence 10 - 1. Screens no. 1 - 3, covering the primary functions, may also be cycled by
repeatedly pressing the “Menu” button.
The screen layouts are outlined in Fig. 2.2 through 2.11. The various Soft Key button functions are described
with each screen.
All Screens have 10 vertical subdivisions.

PRINCIPAL FUNCTIONS
Bottom detection
GDS101 employ a bottom detection algorithm that will try to extract the bottom signal from all kinds of
noise and secondary echoes. When GDS101 is tracking the bottom normally, a thick black line is shown,
and below that, a ribbon with a hatched pattern. This pattern has two levels of hatching. The darkest represent strong and unambiguous bottom echoes. The lighter hatching represents weaker signals possibly
occasional detection misses. If the software can detect no bottom for several pings, the hatched ribbon
disappears.
During normal bottom tracking, a digital value is shown by the bottom contour at the right side of the
screen. If the software algorithm losses track of the bottom altogether, a warning beep is heard and the
black line and hatching band disappears. A warning message: “Lost bottom” is shown in the screen’s
lower right corner.
Ping to Ping filtering
Part of the bottom detection algorithm is the ping to ping filtering. The next bottom is searched for in a
time and strength window based on the strength and timing of the previous bottom echoes. This procedure reduces the probability of tracking schools of fish or secondary echoes as bottom.
If no bottom is detected in the calculated window, the window is gradually increased in size until the full
time and strength window is used.
Bottom Search Range
The FIX RANGE function in Screen 9 is used to control the search range for the bottom detection algorithm. When this function is on, bottom is only searched for within the selected display range. When the
function is off, bottom is searched for within the entire functional range of the echo sounder.
Power ON/OFF
During normal daily operation, the system may be switched off from Screen 2. This operation does not
disconnect the system from the power supply, but all power consuming components are switched off. The
system may be switched on again by pressing any button.
Do not run the sounder for a long time without a submerged transducer connected.
Alarm acknowledgement.
When the depth alarm is activated, the alarm may be acknowledged by pressing any button.
22
FIXED KEY FUNCTIONS.
Depth Range
The Depth Range button can be used to set the depth limit between 10 and 1600 m. Standard values
available by repeatedly pressing the button are 10, 50, 100, 500 and 1000m.
Picture Speed
Picture speed may be referred to either time or Vessel speed. If no speed log is connected, Picture Speed
will always be referred to time. (“mm:ss/div”).
Time referenced Picture Speed may be selected between 20 Seconds per division and 5 minutes per division.
Vessel Speed referenced Picture Speed may be selected between 0.04 nm per division and 5 nm per division.
If a speed log is connected, it is possible to select a “speed/div” unit in Screen 5.
The ping-rate range depends on the Depth Range, and the fastest ping rate at shallow depths is about 5
pings per second.
Menu
The menu button facilitates selection of one of the 10 screen and soft key layouts. The 3 primary operation screens may be cycled by repeatedly pressing the MENU button. Access to the remaining screens
is through encoder operation. The screens are cycled in an endless, bi-directional loop, e.g. turning the
encoder counter-clockwise, will activate Screen 10 after Screen 1.
Turning the encoder with no buttons pressed always force Screen 1.
Day / Night & Back light adjustment
Back light may be continuously controlled by means of the appropriate buttons and the encoder. Press
either button and rotate the encoder until a satisfactory setting is obtained, then release the button.
Day / Night vision see chapter 1. INTRODUCTION System Summary for Color bar explanation.
Day / Night vision may be changes by means of pressing the Day / Night Button. ( see fig. 1.1 )
The settings are maintained in the non-volatile memory, and the last settings are restored on power up.

SOFT KEY FUNCTIONS.
Gain
Gain may be adjusted from 0 to 100% to allow for optimal echo levels from bottom and other objects.
The GAIN setting affects signals from all depths.
TVG
Time Variable Gain may be adjusted from 0 to 100 % to allow for detailed echo control from the 0 - 50
m depth range.
A low setting will reduce the gain in the area near the surface to suppress noise and unwanted echoes
from this area.
Digital indication
On the operation screens, two sizes of large digital depth indicators may be selected from Screen2.
“Small” digits occupy approximately 40% of the net echo-gram screen width.
“Large” digits occupy approximately 55% of the net echo-gram screen width.
Frequency
The Frequency selector toggles among 38, 50 and 200 kHz.
Output Power
Power may be adjusted from 10 to 100 % in case of difficult shallow water conditions. Too high power in
such cases will possibly saturate the receiver or cause detection of unwanted secondary bottom or surface
echoes.
When a range of 10m is selected, Output Power is automatically limited to 10%.
Draught
Draught may be compensated to allow real depth from surface to be shown on the screen and printout.
Negative draught values may be entered to compensate for transducers fitted above the keel.
This setting also affects the NMEA transmitted values.
Draught compensation is indicated on the screen by a flashing number to alert the operator to the fact that
the shown depth value is adjusted.
External Printer Operation
The optional external printer is started and stopped by the Print buttons. The printer may be used for
continuous printing over a period of time or the current screen contents may be dumped to the printer for
reference if something interesting is observed.
The Print buttons switch continuous printing on and off.
The Mark buttons will write a line mark on the paper if it is pressed whenever the printer is running.
If the Mark button is pressed when the printer is off, this will initiate a screen dump of the present screen
contents.
If printer is switched of, or Not connected print button is “Dimmed”.
24
Alarm settings
Depth alarm settings are performed from Screen 1. Alarm limits are referred to the indicated depth.
The local alarm buzzer may be disabled from screen 9, but the external alarm relay will always operate.
The only way to disable the alarms completely, is to reduce the shallow alarm to zero depth and increase
the deep alarm to maximum range.
An active shallow alarm limit must be less than an active deep alarm limit. Alarm limits are enforced
with hysteresis.
A depth alarm may automatically start the optional printer if this function is enabled on Screen 4.
Clock and Calendar Settings
Manual Clock and Calendar adjustments are carried out in Screen 4. If a Satellite navigator giving UTC
messages is connected to the NMEA input, the clock and calendar will be automatically updated and
manual adjustment is not required.
History Memory
GDS101 has a 24 hour history memory. Depth, time and all available navigation data are stored continuously so that the last 24 hours of information is always available.
The history memory is controlled from Screen 7.
The normal history modes are “on” and “recording”. New depth information is continuously stored in the
memory while the oldest samples are discarded. Only bottom information is stored along with time and
whatever navigational information is available in the GDS101 (Position, Speed, Heading).
By switching history “off”, the stored 24 hours will be kept in the memory and no new samples will be
written. As a warning that the memory is not recording, “History off” is flashing at the bottom of the
screen.
History modes “on” and “playback” will start playing the contents of the history memory on the screen
and on the optional printer if it is running. As a warning that the displayed bottom contour is from the
memory and not real time, “History” is flashing at the bottom of the screen.
The “history hours” and “history minutes” buttons used with the encoder, will enable positioning within
the 24 hour memory to observe the desired part of the time frame during playback.
25
Simulator
The GDS101 contains a built in simulator to exercise the screen and various interface signals. The simulator may be switched on and off on Screen 9.
When the simulator is operating, “Demo” is flashing at the bottom of the screen.
Status Screen
The Status screen, Screen 9 shows a list of various system parameters useful for documenting system
set-up and system operating status. The contents of this screen will be valuable information in situations
where manufacturer support is required.
Oscilloscope Screen
The Oscilloscope screen, Screen10 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.
Non-volatile Parameter Memory.
The system contains non-volatile memory to maintain installation and user parameters like Language and
unit of measurement selection, Contrast and Backlight settings, etc.
These parameters are kept in EEPROM memory and are automatically restored on power up. If the user
parameters have never been set, default values are used.
26
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 remote keyboards.
Remote Sounding Control.
This option lets the GDS101 being controlled remotely in synchronised, burst or single ping modes. If
installed, this option is accessible on Screen 3.
Auto Range
This option will automatically adjust the depth range to maintain the bottom contour within the middle
half of the screen height. If installed, this option is accessible on Screen 3.
When the optional printer is started, Auto Range is automatically disabled, and the present depth range is
selected as fixed.
Sound speed calibration
This option will enable adjustment of the sound speed value used for the depth calculations. The standard
value is 1500 m/s, but the user may set values from 1400 to 1550 m/s to accommodate accurate propagation speed in known water conditions. If installed, this option is accessible on Screen 3.
External Printer
Printer for endless paper or inkjet printer for single sheets ( ask for actual type) may be connected
for hardcopy requirements.
27
3. USER MAINTENANCE
TRANSDUCER MAINTENANCE.
The transducers are virtually maintenance free, but occasional cleaning may be necessary depending on sea
water conditions.

Operation and Installation Manual
TRANSDUCER INSTALLATION.
Location.
Single transducers are normally installed in the foreship. Larger vessels are often fitted with two transducers, one fore and one aft.
Optimal system operation is achieved by fitting the transducer as deep as possible on the hull.
The transmitting surface of the transducer must be installed horizontal. On vessels with a deep keel, if the
transducer must be fitted higher than the keel, it should be fitted towards the side, as far from the keel as
possible to avoid false keel echo.
Do not mount transducers close to the propeller or aft of other hull installations (outlets, vents or other
protruding details).
It is of course necessary to select a part of the hull that is submerged under all load and speed conditions,
and to avoid positions where air is trapped in heavy weather.
If a flat, horizontal section is not available for transducer fitting, the shipyard must construct a suitable
bed.
Protect the active element of the transducer and do not paint the surface.
Transmission in the air must be avoided! This may cause mechanical damage of the element.
Installation Details.
Refer to SKIPPERs standard installation procedures in the appendix regarding tank installation, welding,
Cable glands etc.

TRANSDUCER JUNCTION BOX.
The standard cable fitted on the transducer is 25 m and may be shortened or extended. The junction box is
used to interconnect the transducers fixed cable to a yard supply extension cable if the total required cable
length is longer than the standard cable. It is recommended to run the standard cable in a steel protecting
pipe.
Special requirements apply in areas with Ex conditions. The junction box must always be mounted outside
such areas.
Interconnect the transducer pair and its screen in the junction box,but do not ground the screen here.

Select a position to provide free view of the panel as well as easy access during operation and service.
The operator unit may be mounted flush in a panel or directly onto a bulkhead. Fig.4.3 shows the operator
unit along with the main installation dimensions.
If the unit is to be flush mounted, the shown cut-out and recession depth dimensions must be observed.
Remember to leave room in front of the unit to open the door a full 90 degree.
Do not perform installation work with system power applied!!
Cables are led through the appropriate cable glands as follows:
The cable from the transducer(s) should normally occupy the left gland. The right gland is used for power
supply connection whereas the centre ones are used for any interface signals connected.
Power supply may be either 230V/115V AC or 24V DC. Power consumption is appx. 50W at 24V, appx.
70W at 115/230V.
The transducer is always connected with 1 pair plus screen. See Fig 4.7.
If the AC power system is 115V, GDS101 may be prepared for 115V AC by re-connecting the connectors
J102, J103 as shown in Fig. 4.4

STPRINT +
STPRINT -
Transducer Control Input +.
Transducer Control Input -.
STPRINT-/STPRINT+ input is processed as transducer selector input (open - FORWARD/PORT transducer selected, closed - AFT/STARBOARD)
Low frequency indication
When the 38 KHz transceiver channel has been modified to a different frequency, it is possible from
screen 5 to adjust indicated value. Softkey SET LOW has five preset values (24/28/30/33/38 KHz) and
encoder must be used to set any other value in the range of 10-200 KHz, when desired. Note that the
38KHz channel must be activated first (Screen 2, button “FREQUENCY”).
Also, note that after Master Reset procedure the value is reset to factory default, and should be reentered, if the actual value is different.
50
NMEA Setup
Screen 8 is used for verification of received NMEA messages and control of transmitted NMEA depth
messages. Two digital communication channels are provided: primary NMEA 0183 (J303, RCV1A/BXMT1A/B) and secondary RS232C/NMEA 0183, available on J303 (NMEA: RCV2A/B-XMT2A/B) and
J303 (RS232C). Each channel can be programmed individually with respect to the baud rate and scope
of transmitted messages. Before configuring of the required channel, it must be selected by the mean of
softkey IN/OUT. Primary channel is called NMEA, while secondary - RS232. Note, that text window
will represent information, which corresponds to the currently selected channel. The type of displayed
messages - received from external talker (if connected) or transmitted by the sounder is selectable by the
mean of softkey DISPLAY. For more easy analysis of the window contents, display can be prevented
from continuous update, if “DISPLAY off” is selected. The baud rate may be set to 4800 or 9600, 4800
being the more common.
Transmitted messages are enabled individually by the mean of pair of softkeys MESSAGE and STATUS.
To enable/disable particular message, select it from the list by pressing MESSAGE button until required
message is appeared on the same button and then select the status of this message (on/off) by pressing
STATUS button. It is advisable at this stage to set display in “output” mode, to be able to observe current
scope of transmitted messages.
Transmitted talker identifier is SD, Sounder Depth. The following NMEA 0183, v3.0 messages may be
transmitted:
Depth & Draught
Depth below surface
Depth below transducer
Depth below keel
[Fore/Aft] transducer
