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 propri-

etary 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.

4.8.1.2 C-Link serial connection

The two chart plotters should be connected via serial ports. Any of the avail-

able ports can be used, the software will recognize automatically the serial ports

used. A typical connection is as follows:

Chart Plotter 1 Chart Plotter 2

TX —————> RX

RX <————— TX

GND <————> GND
