System Summary
The SKIPPER EML224 Graphic display is a navigational speed log display for Speed through water.
The system containing sensor (transducer), display (operator) unit and an electronic unit.
The sensor can be delivered in many different versions to fit functionality demands and different hull
installations.
The LCD can display a number of parameter in both numerical and graphic forms. The information
from the sensor may includes longitudinal and transversal speeds, drift angle and sea temperature. It is
thus possible to get a very good picture of the vessels total movements.
All IMO requirements are met or exceeded. Comprehensive interfaces are available including NMEA
0183 input and output.
Sensor
There are 2 sensor options:
2 axes EML224 Electromagnetic sensor
1 axis DL1 Doppler sensor
The sensors can be fitted into various tank or sea valve options.
Electronic unit
The sensor is interfaced through an electronic unit which also contains the power supply.
This unit is normally mounted near the hull fitting, and
two twisted pairs
of cable are led to the display/
operator unit for digital signal transmission. The power consumption of the electronic unit is max. 35W.
Voltage 115/230 V AC and/or 24 V DC.
Operator Unit
The operator unit contains a colour TFT LCD display, a keyboard with fixed keys, soft keys and a
rotating encoder. The function of each soft key depends on the active screen, and the buttons are
labelled on the lower rim of the LCD. The display is backlit and backlight intensity may be adjusted
by the user for both day and night vision. Various user-selectable information layouts, adapted to
typical operational situations, may be displayed continuously on the LCD screen. The operator unit is
normally flush mounted. Operator unit power supply options are 115/230 V AC or 24V DC. The power
consumption is max. 70 Watts at 115/230 V AC and/or 50 Watts at 24V DC.
