04 - NTRIP Modem Configuration

Once power is applied to the unit, it will display VBOX and Racelogic logos along with the serial number and firmware version of the unit. 

When you use the NTRIP Modem for the first time, it becomes a Wi-Fi access point. You can then configure the settings by logging into this access point using your phone or a computer. A webpage is then used to configure the unit to use the internal GSM modem or an external Wi-Fi hotspot to connect to your chosen correction service. Settings are retained after a power cycle.

If the unit is configured to use both the internal GSM modem and an external Wi-Fi hotspot, it will attempt to auto-connect to the Wi-Fi hotspot first on power up.
