Hi I have a furuno gp32 which i what to connect to my laptop. I have a usb to nine pin serial port lead and have installed drivers but when I open the chart program on the laptop it dosnt recieve the gps signal but it dose start going funny lik the cuser jumps al over the place it make need some settings re done . any help would be appreciated. Cheers kevin

This information is not in the GPS instructions.
To reset the GPS, you must click on the arrow UP and together on Power.
The display shows that the system is reset.
Then, the GPS is working properly

Hi!

Your Furuno Does NOT have an internal antenna. You have no choice but to install the external one.

Hope this helps.

Make sure you installed the driver for the serial to USB adaptor cable.

pins 2(-) and 5(+) on a 9 pin serial cable, then you need a usb to serial adapter for input into the computer if you do not have a built in 9 pin serial port on you computer because the usb moves the information faster than the gps signal. gps is roughly 4800 baud, usb is moving so much faster you need a buffer

The display uses a serial interface, otherwise known as a comm port. You can get a USB to DB9 adaptor practically anywhere. Once you have a serial connection, you will need software such as MaxSea to send the waypoint with.

you must use a serial to USB adaptor go in to data 1 or 4 network connector is ethernet protocol!

Not all programming software supports usb. Either find software that supports usb or you can buy add on cards to your pc that will give you a serial port. Hope this helps

This is a problem in Windows where NMEA data is interpreted by the computer as serial mouse inputs. There are various fixes. If you type Windows mininsterpret NMEA serial mouse into Google you will find lots of info.

Hi fire1961,

Downloading data from my FURUNO GP-30 gave me no problems. But it took me long time to figure out why I coudn't upload waypoints and routes to the GP-30 via the serial port in my ThinkPad T30.

I tried nearly everything tested the cable, tested a lot of different software and even wrote a little c-program to communicate with the serial port. I also tried a serial-to-usb converter with no results. Then I stumbled over this RS232 Tutorial. According to this - serial ports are not just serial port but can be divided into three general categories:

The types of driver ICs used in serial ports can be divided into three general categories:

* Drivers which require plus (+) and minus (-) voltage power supplies such as the 1488 series of interface integrated circuits. (Most desktop and tower PCs use this type of driver.)
* Low power drivers which require one +5 volt power supply. This type of driver has an internal charge pump for voltage conversion. (Many industrial microprocessor controls use this type of driver.)
* Low voltage (3.3 v) and low power drivers which meet the EIA-562 Standard. (Used on notebooks and laptops.)

Then I installed the waypoint upload software to my ten years old Compaq Presario and suddenly I could upload routes and waypoints but only via the on board serial port. The serial-to-usb converter didn't still work.

So if people experience no result trying to upload data to these old GP-30's from their notebooks and laptops. Then I think it could be a matter of these Low voltage ports not are able to provide the FURUNO device with enough voltage. See the above RS232 Tutorial.

use the yellow and green check for pulsing voltage on wires with digital meter measuring 12V you must turn on the data in the Furuno menus
