62 User Manual
The Slave will be provided with a few dedicated pages to show the C-Link Navigation
Data received from the Master.
4.4 OPERATIONS
INTRODUCTIVE ELEMENTS
It is important remark, once more, that this function does not transfer the whole
route but just the information relative to the navigation. Such information will be
removed from the Slave chart plotter as soon as the navigation is terminated.
C-Link navigation data is exchanged by using two NMEA-0183 C-MAP proprietary
sentences: $PCMPN,1 and $PCMPN,2.
When the navigation is activated on the Master, it starts outputting the C-Link
Navigation Data. If the Slave is connected, all C-Link Navigation Data received
are stored in its memory and the navigation is started.
The information sent by the Master consists of the following values:
♦
Navigation mode (To Single Destination/to a Route)
♦
Route Name*
♦
Destination ID
♦
Destination Position
♦
Next Waypoint ID*
♦
Range from Destination to next Waypoint*
♦
Bearing from Destination to next Waypoint*
♦
Route Length*
♦
Distance from Destination to Last Route Waypoint*
♦
Remaining Route Legs*
♦
Planned Cruising Speed
♦
Average Fuel Consumption
♦
Initial Fuel Load
C-Link Navigation Data can refer to:
♦
Single Destination navigation
♦
Route Following navigation
Values identified by * are sent only for Route Following navigation.
The Destination Icon, Navigation leg (Fix Position to Destination), the Next Waypoint
Icon and all other relevant C-Link Navigation Data will be shown on the Slave
chart plotter. Any variation of the C-Link Navigation Data on the Master will be
communicated to the Slave so to keep data aligned on both devices.
MASTER CHART PLOTTER
Operating mode
To select the Master mode follow the procedure:
[MENU] + "Advanced Options" + [ENTER] + "C-Link" + [ENTER] + "Primary
Station" + [ENTER]
Master mode is the default factory setting. All regular chart plotters functions are
allowed. As soon as the Destination is placed, the Master chart plotter will start
transmitting all C-Link Navigation Data.
In Master mode the C-Link Navigation Data received from the NMEA port is ignored.
So, if the two chart plotters are both operating in Master mode, the C-Link
Navigation Data sent by the other chart plotter never processed.
Under such condition if the navigation is activated on one of the two chart plotters,
a warning message will be shown to notify that the C-Link navigation data will be
ignored by the other chart plotter.
