1. Introduction
Congratulations on the purchase of your GPS160F Global Navigation Satellite System (GNSS) Positioning Sensor. It is
recommended that this product is installed by a Furuno Dealer or Professional Installer with Furuno experience. You will
need to purchase a suitable 1” x 14 TPI thread mounting bracket for the GPS160F.
The GPS160F utilises the latest in GNSS technology, but is designed to be compatible with the thousands of legacy
Furuno systems still providing reliable service, on boats around the world. Featuring a dedicated “Furuno” mode that
outputs the older NMEA 0183 V2.30 data at 4800 baud, with the sentences, number of decimal places and satellite status
information, that legacy Furuno systems need.
Furuno’s product range is popular, reliable and extensive, which means that there are a large number and wide variety of
older Furuno systems being used around the world. This manual tries to cover the most common Furuno installations,
showing how the GPS160F can be used as a drop in replacement for any GP310/GP320 or GP32 systems that have
failed. If your Furuno product is not mentioned in this manual, please consult your local Furuno Dealer for advice.
Before operating the unit you should also familiarise yourself again with the user manual of the Furuno
equipment that you are connecting the GPS160F to. Pay particular attention to the GPS Interfacing
section and any settings that need to be configured for correct operation.
2. Installation
Before starting installation select a suitable location for the GPS160F Receiver. The unit is water proof and designed for
on-deck mounting. The GPS160F antenna has the popular 1” x 14 TPI thread mount, found in many VHF antennas. A
wide variety of different brackets are available for this type of threaded mount, consult your local marine electronics
dealer or chandlery for more information.
The 1” x 14 TPI thread mount can also be removed by unscrewing the three hex bolts with a suitable Allen Key, allowing
the GPS160F to be flush mounted on a flat horizontal surface. A mounting kit (as shown in the diagram below) is
available from Digital Yacht (Part# X500.400). In this situation, a bead of silicone sealant should be applied around the
antenna, after mounting it, to avoid standing water accumulating under the antenna.

GPS160F Power/Data Cable –wire colours;
The GPS160F is supplied with 10m of cable and this should be routed
through the vessel to a suitable dry internal location where it can be
connected to the Furuno equipment it will be interfaced with. The cable
can be shortened, lengthened or joined without problems.
If the GPS160F is to be powered directly from the boat’s DC supply, then
a 1 Amp fuse should be fitted in the positive power feed. The unit requires
9.6V to 30V supply voltage and consumes 30mA at 12v.

There have been a large number of different models of Furuno equipment that can be connected to a GPS and to cover
every possible combination in this manual would be impossible. The cable assemblies listed above are the most common
and you will note that the Pin Numbers for the two NMEA RX signals are consistent across all cables (Pins 3 and 4) and
only the colours are sometimes different.
If in doubt as to which Furuno cable you are connecting the GPS160 to, we suggest that you use a multi-meter set to
measure resistance or continuity and with the cable disconnected from the Furuno equipment, check what wire colours
are connected to Pins 3 and 4, which are always the two pins that our GPS160F needs to connect to.
When replacing a Furuno GP310 or GP320 sensor, the easiest method is to use the existing 10m cable which has a 7 Pin
connector that plugs in to the Furuno equipment. Find a suitable location to join the two cables and cut the existing
GP310/320 cable and remove the faulty sensor. Now join the GPS160F cable to the remaining section of the GP310/320
cable as shown in Figure 1 below.
The connections should be made in a dry location and Digital Yacht do sell a Junction Box (JB1) that can be used to
make a professional and reliable connection between the two cables.

3. Wiring Diagrams
The following diagrams show how to wire the GPS160F to the most common Furuno installations. In most cases, the
GPS160F will just work with no changes to the menu settings of the Furuno equipment. One exception is the GP7000
series of chart plotters, where you need to turn off the internal GPS by going to MENU>ADVANCED>INPUT/OUTPUT
and set INTERNAL GPS to OFF.
