NI300X NMEA Interface Unit
The NI300X NMEA Interface Unit is normally installed inside
of a console or locker close to navigation receivers, radar, and
instruments to keep the 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 and 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 locations with 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!
