SYSTEM CONFIGURATIONS
All NavNet products incorporate a “network circuit board” to integrate each NavNet product
on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is
assigned an IP address to enable transfer of images between other NavNet products. For
example, video plotter pictures can be transferred to a radar and vice versa. Pictures
received via the NavNet may be adjusted at the receiving end.
The number of display units which may be installed depends on the number of network
sounder connected. For a system incorporating three or more products, a “hub” is required
to process data.
For one network sounder: one radar and three plotters
For two network sounder: one radar and two plotters
