AquaNav PC Quick Start Guide
Installation Step 3
On the rear of the AquaNav PC is a single black cable that has eight wires. This is the Power/IO cable. Connect
the Red (+) and Black (-) wires in the Power/I
O cable to the ship’s 12v DC supply.
Ensure that the supply is connected via a suitable fuse or suitable circuit breaker (in the positive power
connection).
A 5A fuse/circuit breaker is recommended for most installations and 10A is the maximum value that
should be used.
Do not try to turn on the AquaNav PC yet.
Installation Step 4
The bottom black cable has eight wires and is the Navigation cable for connecting the GPS150 antenna and also
interfacing the High Speed NMEA Output (38,400 Baud) of the AIS to other navigation equipment. This cable is
terminated in a terminal block.
After mounting the GPS150 and feeding the cable through to the AquaNav PC, connect the GPS150 cable to the
AquaNav Navigation cable as follows;

If you wish to take the High Speed NMEA0183 GPS and AIS data out to another piece of navigational, then use
the following two wires of the Navigation Cable;
o
Orange (TX+)
o
Brown (TX-)
Remember that this data is high speed NMEA0183 data and you must set the equipment receiving this data to
accept data at 38,400 baud rate, which is the standard for AIS data
Please note that the GPS150 and built-in AIS receiver are powered directly from the main +12v supply connected
to the AquaNav PC and remain powered even when the PC is shut down. This allows the GPS and AIS units to
be run independent of the PC which can be useful on sail boats where constant running of the PC can cause
power consumption problems.
To ensure that the GPS and AIS are powered down, it is necessary to turn off the circuit breaker that provides
power to the AquaNav PC.
Feed the coax cable from a dedicated AIS/VHF aerial or from a suitable VHF antenna splitter to the AquaNav PC
and connect it to the BNC connector on the rear of the unit.
