Establishing Connections

Internet Setup

The next step will depend upon the connection method. It will usually be a phone/modem. It may rarely be wi‐fi. When one picks Phone/Modem the list of paired devices will appear in the drop‐down list. If a new connection is to be established click New/Edit. If the procedures on page 2 and 3 were followed one simply chooses from the drop‐down list. 


GNSS Contacts

Choose Connect if C4Gnet already exists.
Choose New if not. The necessary setting follow. 

The desired network connection previously setup will be inserted. (The NTRIP username and Network Connection and APN are example and likely NOT to be correct.)

Entering a URL ( is more desirable than a numerical IP address because if the servers change IP, the URL stays the same simply pointing to the new IP. If the numerical IP is required, contact C4G for the most current. Click Store.
