Northstar 8000i System - 12" Display Processor Installation Manual 
5 
The Network Master Unit 
The simplest type of 8000i System consists of a single stand-alone processor. A more 
sophisticated 8000i System consists of multiple processors, which can be a combination of 
12" Display Processors or Black Box Processors, networked together. 
If more than one processor is used in the 8000i System, one processor only MUST be 
specified as the master unit
. You must decide which processor on the 8000i network will be 
responsible for handling incoming and outgoing navigation data. Therefore, when planning 
the wiring, make sure that all the data inputs and outputs, such as NMEA, are supplied to the 
master unit. Typically the master unit will be located at the main helm station. 
The master unit MUST: 
ƒ 
have all the data wiring (such as NMEA) run to it. Incoming navigation data, such 
as GPS and NMEA, is received by the master unit and then distributed over the 
network to other processors.  
ƒ 
have the GPS antenna connected to it. 
ƒ 
have the chart license key connected to it. When the chart license key is 
connected and the charts unlocked, other processors can share the one license  
(see "Northstar 8000i C-MAP Chart License Key" page 25) and display the charts. 
ƒ 
have the autopilot connected to it (if applicable). 
ƒ 
have a USB port accessible by using the provided panel mount cable (this is to 
allow easy access to upgrade the system) 
The master unit MUST be operating FIRST in order for the other processors to function with 
navigational information.  
If the master is NOT operating, all the other display units will show a grey screen with the 
message  "Master [name] unavailable". This will be the case for Chart, Radar, Sounder, 3D 
Chart and 3D steer.
