4.27 External Alarm

The external alarm circuit has an open collector output for an external alarm
relay or buzzer. The alarm voltage is the same as the main supply voltage.
Max. load on external alarm output is 0.9 Amp.

4.28 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 Simrad/Anritsu 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 Simrad/Anritsu or Furuno is selected in the Installation
Setup Menu.
12V out is for driving (max. 3) IS15 instruments (max 250mA load).
