4. C-LINK
C-Link system is a feature which allows to share the same cartographic data
between two chart plotter units (CP) linked via serial I/O port.
In order to activate C-Link function, a “MAX data C-CARD” (called REGULAR C-
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 s/w
versions that allow C-LINK function.
4.1 HOW C-LINK SYSTEM WORKS
When the CP is powered up, it switches into the “Stand-Alone Mode”. Whilst in this
operation mode, the CP 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 CPs) a special con-
nection is established between the CPs to enable the MIRROR C-CARDs.
If a regular C-CARD which has previously activated a MIRROR C-CARD is re-
moved, even the MIRROR card will be not read anymore on the other unit.
4.2 C-LINK SERIAL CONNECTION
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:
CP1 CP2
TX —————> RX
RX <————— TX
GND <————> GND
NOTE If the serial port used for the connection is Port 1 (optoisolated) do not forget
to connect the "Input 1-" signal (Green Wire) to the GND wire.
