SECTION FOUR: Networking the
Northstar 6000i
The 6000i uses Northstar’s new N2 networking technology. N2 technology is based on the Ethernet
standard, conforming to the IEEE 802.3u 100Base-TX specification (also referred to as “Fast
Ethernet.”) A single cable with standard connectors simply plugs into each unit. Using N2 technology,
multiple
6000i displays can automatically:
•
Share charts between units. Charts from a cartridge inserted in the master unit are
available on all networked units. Charts from a cartridge inserted into a slave unit are
available on that unit.
•
Share all waypoints and routes between units. Any changes made to the waypoints and
routes in one unit are copied to the other units with no action by the user. Waypoint and
route navigation control is available from all networked units.
•
Share echosounder data from the Northstar 491 between units. The 491 can be controlled
from any display unit.
•
Share radar data from Northstar radar between units. The radar can be controlled from any
6000i display. The radar overlay function can be used on only one display at a time.
NTSC video is not shared over the network because of bandwidth limitations. A separate coaxial
video cable must be run to each display unit that will display video.
Waypoint and route transfer between a 6000i and a Northstar 951, 952, 957 or 958 is accomplished
using the
AUX
port as described in “Using the Aux Port” starting on page 39.
Waterproof Ethernet cables can be ordered from Northstar in a variety of lengths. Ethernet cables are
not included with the unit, since types and lengths vary by installation.
Networking setup
In any N2 networked installation, one and only one 6000i must be designated as the master unit. All
others are designated as slaves. All 6000i units are shipped from the factory configured as
masters, and any units that will be used as slaves must be reconfigured before they are
operational.
To designate a 6000i as either master or slave, press and hold the
STAR
key for about a
minute or so while turning the unit on. A special screen is displayed that allows selection of the
proper mode.
The GPS antenna must be connected to the master unit.
It is recommended that the optional radar and/or echo sounder, and other NMEA devices also be
connected to the master unit, for two reasons:
NOTE:
This entire section can be ignored for a simple installation
with no networking involved, or for an installation that involves only
traditional NMEA connections.
