Important
• During installation, DO NOT CUT THE TRANSDUCER CABLE. The transducer,
transducer cable and transceiver cabinet are all “balanced parts”. Therefore cutting the
cable may deteriorate performance and will also void the warranty.
• During installation, consideration must be taken, such that the sensor and cable can be
removed for service purposes. Filling pipes or tubes is not recommended unless strictly
necessary.

1. Introduction
System Overview
The system is a navigation, 2 axis (transversal and longitudinal) Doppler speed log with a large
LCD. The display graphics is continuously shown on the LCD along with available navigation
details. Comprehensive interfaces are available including IEC 61162-1:2007(E) (NMEA 0183) input
and output. All IMO (International Maritime Organization) requirements for speed logs are met or
exceeded.

Sensor (Transducer)
The Doppler sensor consists of a head with 3 hydro-acoustic elements. The elements are transmitting/
receiving acoustic signals at 270kHz. Out of the received doppler shifted frequencies it is possible to
calculate the speed in 2 axis. The sensor is connected to a transceiver cabinet located within 40 m of the
sensor.
Transceiver unit
The connection from the transceiver cabinet to the operator unit is via a serial RS-422 data link and may
be up to 1000 m. Transceiver and operator unit power supply options are 115/230 V AC or 24 V DC. The
power consumption for the transceiver unit is app. 80 Watt at 115/230 V AC or 60 Watt at 24 V DC.

Interfacing
The display unit has various interface possibilities.
Outputs
• 3 log pulse outputs 10/100/200/400/1000 pulses per nautical mile, see “Log Pulse Outputs” on
page 46.
• 2 outputs also gives speed direction, see “Log Pulse Outputs” on page 46.
• 3 analogue outputs 0 - 10 V or 4 - 20 mA, see “Analogue interfaces” on page 47.
• IEC 61162-1:2007(E) (NMEA 0183) interface output of speed/distance, temperature and depth
information, see “Softkey” on page 89.
• Power failure alert, see “Power failure relay” on page 45.
• Speed limit, see “Speed Limit function” on page 46.
• External VGA monitor, see “External Interface Ports” on page <?>.
Inputs
• IEC 61162-1:2007(E) (NMEA 0183) interface input for position, rate of turn, heading and UTC
(Coordinated Universal Time), see “Softkey” on page 89
Alarts
A power failure alert is provided on a potential free relay contact. This may be used for interface to
external alert systems.
The operator unit contains a graphic LCD display and a keyboard
with xed keys, softkeys and a rotating encoder.
The function of each softkey button depends on the active screen,
and the buttons are labelled on the lower rim of the LCD.
The display is back lit, and back light intensity may be adjusted
by the user. Various user-selectable information layouts adapted
to typical operational situations, may be displayed continuously
on the LCD. The operator unit can be ush mounted, wall
mounted or bracket mounted.
Operator unit power supply options are 115/230 V AC or 24 V
DC. The power consumption is app. 70 Watt at 115/230 V AC or
50 Watt at 24 V DC.

Screen Select
The screen select button facilitates selection of one of the 7 screen and softkey layouts. The 3 primary
operation screens (Screen Pilot, Screen Docking/Shallow Water and Screen Open Sea) may be cycled by
repeatedly pressing the SCREEN SELECT button. Access to the remaining 4 screens (Screen Com, Screen
Status, Screen Calibration and Screen Diagnostic) is done by pressing the “Screen select” and at the same
time turn the “encoder”.
Day/Night
Day/Night vision may be selected by pressing this button. These two modes diers by colour presentation,
which are optimized for dierent ambient light conditions.
Brightness
Backlight may be controlled by using the appropriate button and the encoder. Press the backlight button and
rotate the encoder until a satisfactory setting is obtained, then release the button. The settings are maintained
in the memory, and the last settings are restored on power up.
2. Operation
When the installation is complete, and power is connected to the operator unit, the system is switched on/o
by a power switch inside the cabinet.

Parameter entry
The xed function buttons and the softkey buttons along with the rotating encoder, facilitates entry of
parameters and other data. The following owchart illustrates the procedure for changing settings. The
various screens are shown in detail in the operation section.
Primary Screens
Each of the operation screens contains a graphic picture and one or more menu sets congured on
the 6 softkey buttons. The three rst screens are covering the primary functions. Manoeuvring within
these screens are easily done by pressing the SCREEN SELECT button.
The various screens can also be selected by keeping the SCREEN SELECT button pressed and
rotating the encoder in either direction. Turning the encoder clockwise cycle the screens as shown in
gure below, and counter clockwise rotation cycles the screens in the opposite direction.
The screen layouts are outlined in the following pages. The various menus and softkey functions are
described with each screen.

“Hidden” button
Enabling advanced parameters with Hidden button
To avoid accidental access to the internal settings, some advanced functions are disabled during normal
operation. In order to enable them, do the following:
• Open front door of the cabinet and nd a “hidden” key on the component side of the keyboard PCB (upper/
left corner of the PCB).
• Press key mentioned above and keep it pressed for 2 seconds, until you hear 1 beep.
• The text on the advanced function soft keys will change colour from grey to white, which indicates availability
of the corresponding functions.
•
• There are 2 levels of advanced functions. Function enabled by 2 beeps (4 seconds) may interfere the speed
log performance and should normally not be changed.
• To reset all settings to default, See”RESET FACTORY” on page 26
