Communicating with the product
Our NAVbase software, which is supplied with the GPS-Base, is used to configure the
product and monitor its operation. Using NAVbase you can:
• Average base-station location
• Enter base-station location, if known
• Restore a saved base-station location
• Program a location in to the GPS-Base so it will use it after power is removed
and restored
• Set the base-station identifier GPS-Base
• Change the format of the corrections
• Monitor the status of the GPS-Base
• Save differential correction data to disk
To communicate with the GPS-Base the NAVbase software needs to know which "port" the
GPS-Base is connected to. The GPS-Base connects using USB, but the USB drivers makes
the GPS-Base appear as a serial COM port. Normally the driver will install three COM ports
for the GPS-Base: COM5, COM6 and COM7. Any of these can be used. If these ports are
taken by other software drivers then other ports will be used and it will be necessary to
"search" until the correct port is found.
The GPS-Base automatically scans all the available ports on start up and only lists the ports
where a valid GPS-Base has been detected.
