5. C-LINK
Navigation Data Transfer
This function allows transferring C-LINK navigation data (Route Name, Destina-
tion ID & Position, Next Waypoint ID & Position, Total Route length, Fuel Con-
sumption Rate, ETA, TTG etc.) (Hereinafter “C-LINK navigation data”) between
two chart plotters linked through the C-LINK system.
The chart plotters can be set to operate in two modes:
- MASTER mode (Primary Chart Plotter)
- SLAVE mode (Secondary Chart Plotter)
When the navigation is activated on the Master chart plotter, the C-Link naviga-
tion data will be continuously sent to the Slave until the navigation is active.
If the Master is navigating to a Single Destination, the Slave will show the Desti-
nation position and activate the navigation to it.
If the Master is navigating to a Route, the Slave will show the Route Leg com-
posed by the Destination and the Waypoint after the Destination (Next Waypoint)
and activate the navigation to it.
Any variation to the current C-Link navigation data will be transferred from the
Master to the Slave.
The Slave will be provided with a few dedicated pages to show the C-Link naviga-
tion data received from the Master.

OPERATIONS
INTRODUCTIVE ELEMENTS
It is important to 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
