DC Power Connection
The chartplotter is intended for use on ships’ DC power systems operating in a
nominal range of 12 - 32 V (absolute maximum range 10.7 to 44V DC).
The connections should be made at a power distribution panel via an isolation
switch. Check that all connections are clean.
➤ Connect the power supply using the standard power cable supplied, as follows:
1. Connect the moulded power plug to the power connection on the rear of the
chartplotter. Run the free end back to the vessel’s distribution panel.
2. Cut the cable to length and connect the red wire, via a fuse, to the +ve
battery terminal and the black wire to 0V (-ve battery terminal). Protect the
circuit with a 5A fuse/circuit breaker.
3. Cut any unused cores short, or use a suitable junction box to connect to
NMEA equipment and/or a printer.
CAUTION:
To minimise the risk of fire and other hazards, if you do not have a breaker
in your power circuit, you must fit an in-line, quick-blow fuse to the
positive (red) lead of the power cable
Note: If the power connections are accidentally reversed the system will not
work. Make sure that the input power leads are connected for correct polarity,
using a volt meter.
NMEA Connection
You can use this port to interface the chartplotter with other equipment capable
or receiving/transmitting data to the NMEA 0183 standard. Appendix B defines
the data received and transmitted on the NMEA port.
