Transfers to GP30 series except GP33
The GP30 and similar units operate as slaves in a master/slave communications relationship. This means that the PC
controls the transfer. This transfer uses the companion Furuno loader that is found in Tools>Upload/Download
GPS>Furuno or the one in the following section. This brings up the Furuno loader screen.
This program was developed for the Ozi Explorer and not by the Andren Software Co. Thanks to the OZI folks for
allowing it to be used for this application. After connecting the GPS to the PC set such GPS things as NMEA PORT1
with the output format set to NMEA0183 Ver2.0. Make sure that the port can communicate both ways (input and
output) and not just output. Now, on the PC in the Furuno program, set the Port to what the GPS is connected to. If you
are unsure of this, try to Read GPS with various settings. Once a GPS is found and communicating, it will fill the blank
part of the form with data it is receiving. You may have to go to the GPS to tell it to transfer data. I don't have a Furuno
to try it on or I would have filled in the example above. If your PC does not have a serial port (it looks like the monitor
port, but is male instead of female) then you need a USB to serial converter device. To see where your GPS is
connected, read the first part of chapter 6.6.
Now, we are ready to use the downloader program.
