GPS Cable Connection – Windows 8/10 – GPS Trackmaker

The cables we sell, provide a USB Serial connection to and from the GPS unit. It is not possible to access the waypoints, tracks or routes on the GPS directly. You need some software in order to communicate with the GPS unit. Typical software include Anquet, Memory Map or Fugawi. Please note that you will have to purchase them from another supplier. It is possible to download free software such as Gartrip, GPS Babel or GPS Trackmaker.

We have a guide to set up a connection with GPS Babel here.

In order to set up a working connection between your GPS and your computer, you firstly need to install the drivers. These are supplied on a mini CD along with the cable. If you have lost the mini CD, or cannot access it from your computer, and are using a eTrex Cable, this uses PL2303 USB-Serial converters, which can be downloaded from here. For the GPS 12, 38 and 40 cables, they require the CP210x drivers, which are available here. Once you have followed the instructions on the screen.

Once the drivers are installed, please insert the cable into a free USB slot. Once you computer has identified the drivers for the cable, you now need to identify the comm. port number which has been allocated to it. To do this in Windows 8 or 10, you need to search in the Windows menu for “Device Manager”

In the list, there should be “Prolific USB to Serial Comm Port (COMX)”. In the above example, Com. 5 is the port associated with the USB eTrex Data Cable. Take a note of the ComX number as you will need this for the next stage.

Next you need to open GPS Trackmaker. If you don’t already have it installed, you can download it for free from
