Section 5 - Network Settings for Multiple
Display NavNets
Since NavNet products use ethernet 10Base-T networking protocol, each unit works as a
“Node” in the NavNet network. When two or more NavNet components (Including The
Network Sounder) are networked together, the IP Address, Host Name, etc must all be
coordinated for each unit in the network. This information should only need to be
registered once for the life of the product.
(Note: to access this menu, you must be in the “Installation Mode.” To get to the menu
below, hold down the MENU button while powering up the display, then press MENU,
SYSTEM CONFIGURATION, INSTALLATION SETUP, NETWORK CONFIGURATION.)
HOST NAME – This is the name of the display as it is
recognized by other displays in the network. It may
be labeled with up to 8 numbers or alpha characters.
For example, in a 3 station NavNet, you may label the
displays “A,” “B,” and “C.”
IP ADDRESS: The important thing about this
number is that the last three digits must be
different from any other display in the NavNet
network. Usually, this number only has to be
changed if there are identical displays in the
network.
RADAR SOURCE: This entry must contain the host
name of a radar display. The “A” selection in this
example means that this display is set as a plotter
and it is getting its radar information from radar host
“A”.
If the NavNet Display is a radar display, the HOST
NAME and the RADAR SOURCE must match (i.e. “A”
& “A” for the radar display in this network). If there is
no radar in the network, it should be blanked.
CHART SOURCE: Each NavNet display has a chart
card slot. In order for one display find chart
information on another networked display, the Host
Name of the other displays must be entered here.
DO NOT enter this display’s own host name as a
Chart Source, it is automatic.
SOUNDER SOURCE: If a Network Sounder (BBFF1)
is connected via the network, “SOUNDER” should
be entered here. If a Network Sounder is not
connected, it should be blanked.
SUBNET MASK / GATEWAY ADDRESS / OFFSET
PORT NUMBER

not change them.
