The Racelogic NTRIP Modem allows an RTK enabled VBOX to receive positional correction data via Network RTK without having to use a VBOX Base Station. Configuration is made via a Wi-Fi access point and the front screen will display status and connection information.
So that Racelogic can continue to provide you with notification of the latest software releases, firmware upgrades and to offer technical support, please register your NTRIP Modem.

The front panel of the modem contains an OLED screen which displays status and connection information.
The four buttons below the screen do not currently serve any function and are reserved for future use.
The top of the unit houses a slot for inserting a Standard SIM card if are intending on using the internal 4G modem to connect to the NTRIP server, and a USB socket for updating the unit using the supplied USB cable. If you are connecting to another GNSS receiver rather than a VBOX, the USB socket can also be used to power the unit if power isn't available via the Hirose connection.
An SMA connector is also included for attaching the supplied antenna.
The bottom of the unit houses a Hirose connector which is used to connect to a VBOX or other GNSS receiver via the supplied RLCAB170 cable.
More detailed information on the front screen can be found here.
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.
- Attach the supplied antenna to the SMA connector on the top of the unit.
- If you are intending to use the internal 4G modem, insert a data Standard SIM card in to the slot on the top of the unit, with the logo facing the front screen side/ contact facing the rear, chamfered edge in first.
Note: Ensure the card has been activated.
- Connect the supplied RLCAB170 cable from the bottom Hirose connector on the unit to the 'CAN' port of the VBOX 3i or other GNSS receiver. If using VBOX 3i, ensure that the correct DGPS mode has been enabled, more information on this is available here.
- Apply power to the connected VBOX or other GNSS receiver. If you are using another GNSS receiver and power isn't available via the Hirose connection, the modem can be powered from the USB socket using the supplied TTV2AMBBLK1M cable. More information on this is available here.
- The modem screen will display a Wi-Fi hotspot name and IP address which is used for configuration of the unit. Using a phone or a computer, navigate to the Wi-Fi settings on the device and connect to the hotspot name. Open an internet browser and enter the IP address within the address bar.
