5.1 C-LINK
C-Link system is a feature which allows to sharing the same cartographic data
E
between two Chart Plotter units linked via serial I/O port.
In order to activate C-Link
CARD) must be inserted into one of the two chart plotters and a special MAX data
C-CARD (called MIRROR C-CARD) must be inserted on the other chart plotter.
The two MAX data C-CARDs must have the same code and revision. So, the
MIRROR C-CARD can be utilized only on a chart plotter linked to another chart
plotter provided with the equivalent REGULAR C-CARD.
It is important to point out that the two chart plotters must have the update
software versions that allow C-Link
How C-Link system works
E
When the chart plotter is powered up, it switches into the "Stand-Alone Mode". In
this work mode, the chart plotter unit periodically scans all the available C-CARD
slots searching for MIRROR C-CARDs. When one or more MIRROR C-CARD is
found (in one or both chart plotters) a special connection is established between
the chart plotters to enable the MIRROR C-CARDs. If a regular C-CARD which has
previously activated a MIRROR C-CARD is removed, even the MIRRORs C-CARD
will be not read anymore on the other unit.
C-Link serial connection
E
The two chart plotters should be connected via serial ports. Any of the available
ports can be used, the software will recognize automatically the serial ports used.
A typical connection is as follows:
Chart Plotter 1
TX
RX
GND
5.2 C-LINK
This function allows transferring C-Link
tion ID & Position, Next Waypoint ID & Position, Total Route length, Fuel Con-
sumption Rate, ETA, TTG etc.) between two chart plotters linked through the
C-Link system.
E
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
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)
