Geonav Link Network
GEONAV LINK NETWORK
The GEONAV features Geonav Link, a system for the network
connection (Ethernet) of several plotters. This system makes
it possible to transfer the changes to a route - including tem-
porary changes made through the Easy Pilot function - from
one plotter to another. To avoid that the improper use of one
plotter affects any other unit connected to the network, it is
possible to enable the Network Lock function; in this case,
route editing is not allowed. Another innovative feature is the
sharing of the electronic chart among several instruments,
without having to purchase as many charts as the instruments
connected to the network.
NOTE: No GPS receiver suitable for network connection to the Geonav Link has been
put on sale yet. Therefore, it is necessary to connect each plotter to a GPS receiver
by the NMEA0183 standard port. In any case, a single GPS receiver can be con-
nected to several plotters. The autopilot, however, must be connected to only one of
the plotters on the network, still using the NMEA0183 standard port.
Connecting the instruments
The installation of the Geonav Link network, to be carried out
only by skilled personnel, requires the use of Ethernet stan-
dard cables and connectors (UTP cat. 5 cable and RJ-45 con-
nector). To connect several instruments to the network, use
the cable supplied for linking each plotter to an Ethernet stan-
dard hub. To execute a point-to-point link between two in-
struments only, use the cable supplied as well as a crossover.
Once the network has been appropriately implemented, Geonav
Link is automatically detected at start-up and the instruments
are made ready for data transfer.
Setting the network
To ensure a correct network communication, the plotters have
to be assigned network addresses different from those assigned
to any external device (PC, printer, server, etc.) connected to
the same network.

The IP address setting is carried
out through the Setup menu.
Press the GOTO key to display the
main menu, then select SETUP,
GENERAL and position on the
IP ADDRESS option.
A window
instrument's IP address as
192.168.xxx.yyy: set the same
xxx value (0 to 255) for all the
plotters connected to the net-
work, whereas the yyy value (0
to 255) must be different for each
plotter connected.
Set the address range values so as all the yyy values for all the
plotters connected fall inside the first...last range.
Within the same window, the SHOW INFO option allows dis-
playing the network connection status (MAC address, IP ad-
dress, etc.), whereas the PING option allows testing the re-
sponse of an IP address from the network).
Transferring the route
The operations that allow editing an active route - and that
are therefore transferable to all the instruments on the net-
work - are the following:
- Route editing (insertion, deletion and displacement of a
waypoint; recall and deletion of a route)
- Insertion of a waypoint and selection of the target waypoint
by the GOTO function
- Temporary editing of the route by the Easy Pilot function
(EBL knob)
As one of the above operations has been carried out from any
instrument connected to the network, switch from Cursor mode
to Navigation mode by pressing the EXIT key.
