Chapter 6 OPTION FUNCTIONS
6.2 NMEA CABLE
The SMR-715/720 has 3 channels NMEA signal input allowing connecting to navigation equipment, such as
GPS, for own position, waypoints and speed for MARPA tracking.
It also allows connecting a GPS compass for your heading (and MARPA tracking) and / or AIS for displaying
targets.
In order to use the above function, NMEA cable is required.
・
Using GPS receiver, please connect NMEA1.
・
Using NSK, please connect NMEA3.
・
AIS connects all NMEA port available.
The data are received by IEC61162-1/2.
Telecommunications standard NMEA0183 / IEC61162-1/2 is not conformity at all
Communications protocol 4800 bps, start 1bit, data 8bit, stop 1bit, With no parity

6.3 RECTIFIER UNIT
The input voltage range is from DC +10.8V to DC +31.2V. (DC12-24V, -10%+30%).Power dissipation is
about 50W. If ship’s DC battery power supply is not enough to the operation of this radar, we strongly
recommended that to you use this rectifier unit.
AC /DC power converter unit : NBD-865.
