The VBOX NTRIP Modem (RLVBNTRIPMDM) allows an RTK enabled VBOX to receive positional correction data via Network RTK, without having to use a VBOX Base Station. Correction messages received via the RTK network can be an advantage if testing is conducted tens of kilometres away from the base station, over large changes in elevation or where topographical obstacles could get in the way.

If RTK coverage is available, the NTRIP Modem allows for vehicle testing that requires high positional accuracy – such as when validating critical safety systems like AEB/ACC - to be conducted where a VBOX Base Station cannot be deployed.

What's in the box

NTRIP Modem Unit

6-way Hirose to 5-way Lemo plug- 2 m

20 AWG USB Type A ti Micro B Fast Data Charger Cable - 1m

1/4 Wave Monopole Antenna Multi Band SMA

Using the NTRIP Modem with VBOX 3i ADAS

Using SIM Card

Using Wi-Fi Connection

Attach the supplied antenna (ANTMSTUBSMAM) to the SMA connector on the top of the unit.
Insert the SIM card into the slot at the top of the unit.
The logo on the SIM card must face the front of the modem and the chamfered edge must be inserted first.

Notes:
Make sure that the SIM card has been activated before you insert it into the modem.

If the SIM card can be broken down into a Micro/Nano SIM, make sure that it is stable when you insert it into the modem as the Micro/Nano SIM could become detached from the card inside the modem.
Connect the Hirose end of the RLCAB170 to the Hirose connector at the bottom of the NTRIP modem.
Connect the other end of the RLCAB170 cable to the DGPS port on the VBOX 3i ADAS.
This cable provides power to the modem from the VBOX unit.

Note: When you use the NTRIP Modem for the first time, it becomes a Wi-Fi access point
Use a phone or computer to open an internet browser and enter the IP address in the address bar to log in to the modem’s access point.
Press the Change settings button next to the Modem heading.
Enter the APN, Username and Password associated with your network provider.
Press the Save and restart button.
Note: Settings are retained after power cycles.
When it has connected to the network provider, the unit will briefly display a Connected (mobile data supplier) message.

The NTRIP modem will reboot and attempt to connect to the internal modem you have configured. The settings page will be updated with the new settings and provide a connection status indication.
Press the Change settings button next to the NTRIP Caster heading to configure the NTRIP correction service details.
Enter the Server Name/IP Address, Port, Mount Point (correction data stream), Username and Password information (if required).

Note: These details will be provided by your NTRIP service provider.
Press the Save button.

If there is a problem with the server details, the unit will briefly display an Invalid Caster Credentials message.

When it has connected to the NTRIP server, the unit will briefly display the RTCM Streaming message.

The settings page will be updated with the new settings and a connection status indication along with the number of data bytes received from the NTRIP server. The front display will also provide this information.
Check that the DIFF LED on the VBOX is solid green, indicating that it is receiving DGPS corrections.

This cable provides power to the modem from the VBOX unit.

Note: When you use the NTRIP Modem for the first time, it becomes a Wi-Fi access point
Use a mobile phone or a Wi-Fi-capable computer to navigate to the Wi-Fi settings on the device and connect to the modem’s hotspot.
Use a phone or computer to open an internet browser and enter the IP address in the address bar to log in to the modem’s access point.

The need to open a browser and enter an IP address is the same between both SIM and WiFi.
Press the Change settings button next to the Wi-Fi heading.
Enter the name and password of the hotspot you want to use.

Note: The Hotspot must have a name consisting of alphanumeric characters only.
Press the Save and restart button.

Note: The settings are retained after power cycles and the modem will attempt to auto-connect to the Wi-Fi hotspot when powered up.

The modem will reboot and connect. When it is connected, the unit will briefly display “Wi-Fi Connected”.

If it cannot connect to the configured Wi-Fi hotspot on power up, it will automatically restart and become a configuration access point.
Press the Change settings button next to the NTRIP Caster heading to configure the NTRIP correction service details.
Enter the Server Name/IP Address, Port, Mount Point (correction data stream), Username and Password information (if required).

Note: These details will be provided by your NTRIP service provider.
Press the Save button.

Check that the DIFF LED on the VBOX is solid green, indicating that it is receiving DGPS corrections.

Note: If you configure it 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 when you powered it up
