How to Install Node.js and Running the FieldFox Mapping Software
How to Install Node.js and Running the FieldFox Mapping Software 
This section contains the procedure to download Node.js to access 
OpenStreetMap files and to process and save those files using the FieldFox 
mapping software. For details on how to use those on files once they are 
downloaded to the FieldFox, refer to “How to Set Up Mapping Settings” on 
page 390. 
1. Open an HTML5 compatible browser and download Node.js to a PC (e.g., 
Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge): 
https://nodejs.org/en/download
2. Run the Node.JS installation file, by accepting the wizard’s defaults (i.e., 
including leaving the "Automatically install the necessary 
tools. Note that..." checkbox unchecked). Refer to Figure 15-4 and 
Figure 15-5 on page 383. 
IMPORTANT! If your FieldFox is connected directly to the LAN, you can skip 
the section on downloading Node.js and go to “How to Set Up Mapping 
When the FieldFox Is On The LAN” on page 390.
IMPORTANT! 
Do not change the default name of the directory path for downloading the 
Node.js program, because FieldFox uses the default program path name to 
run the Mapping feature. Refer to Figure 15-4.
