NI300X NMEA Interface Unit
The NI300X is normally installed inside a console or locker close to
Nav receivers, radar and instruments to keep cables short. The unit
does not have controls that need to be operated during installation or
use, but you should be able to take the lid off for inspections, to view
LED indication of received signals. It should be installed with the cable
inlet and the Robnet connectors facing down. The NI300X is designed
to operate in a location that provides ambient temperatures below +55°
C (+130° F). It is fastened to the panel/bulkhead by the external
mounting brackets.
Note ! The NI300X is not weatherproof, and must be installed in a dry location!
The NI300X NMEA Interface (expansion) Unit is designed to handle
installations where more NMEA lines have to be tied into the system.
Four NMEA ports are available. An additional output data-port with
DATA/CLOCK signal is capable of generating heading data in the
format used by some radar displays made by Anritzu and Furuno.
This feature is thus added to the system if a J3000X Junction Unit is
installed (J3000X has no radar Clock/Data output as compared to
J300X and J300X-40).
Configuration for Anritzu or Furuno is selected in the Installation
Setup Menu.
12V out is for driving (max. 2) 12V Dataline instruments (max 250mA
load).
