Quick Start Guide for GPS160F V1.00

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.
