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.
A NavNet system may consist of up to four NavNet display units and one network sounder.
For a system incorporating three or more products, a “hub” is required to process data.
