7.1.2 Selecting the Navigation Devices (only available in the Service Mode)
Use the Nav Device Selection command to select from the type(s) of navigation
positioning device(s) you have integrated with ECDIS: GPS, Loran
− C, Transit or
Syledis (column “ Use ”).
We recommend that you select Dead Reckon as an available ”device”. In the
event that the selected navigation device fails, your ship’s course is simulated
using ECDIS’s Dead Reckon feature, see chapter 7.1.4.
If you have integrated ECDIS with a device not listed, use the Custom ID1 and
Custom ID2 boxes to enter a two letter code for the device. The code must
match the one that appears as the NMEA talker ID in the data sentences output
by the device. Please see ”Navigation (Talker) Devices ID (ECDIS)”, see
chapter 12.1.1.1.
ECDIS can use data from only one navigation device at a time. You have to se-
lect from the available devices, which type of device it should use to position
your ship (column “
Primary ”). If the selected device fails, ECDIS switches auto-
matically to Dead Reckon and then you have to select another available device.
To mark the event, ECDIS places a ship mark labeled with a one or two letter ab-
breviation for the new navigation device.
A check mark in the “Display Secondary Position Indicators” is indicating that the
position from a second position device is simultaneously plotted and shown as a
separate symbol (marker). A two letter label describes the sensor type of secon-
dary device.
