Installation guidelines for

the USB to serial adapter

 and USB cables

 

There are many USB to serial adapters available on the market. The instructions below are for the unit that we sell, see www.gpsoz.com.au/usb.htm . These instructions are also suitable for the USB cables that are available from www.gpsoz.com.au/cables.htm#USB%20Cables

 

If you have purchased another brand please contact your retailer or supplier for support. Unfortunately we cannot provide support for adapters that not purchased from us. (However some of the tips below may help!)

bulletLook for the line that says “Prolific on USB-to-Serial Comm Port (COM4)” or similar. Note the number after “COM”. In this example it is 4. This number is needed when you set up your application (eg OziExplorer)

 

You will now need to go to your application and change it to use this new COM port number. The example below is for OziExplorer.

Note: If you are using the Garmin Fleet Management cable, ie connecting OziExplorer to a Garmin Nuvi, make sure you have OziExplorer V3.95.g or later AND the 12v cig plug is plugged in and power is tuned on. You cannot use this cable will the Nuvi is powered from battery only.
 

bulletSelect the configuration option with OziExplorer, File, Configuration

·        Set the General COM Setting to match your COM port number, in this example 4

·        Make sure the other settings match your GPS, for example:
