Configuration of VBOX Sigma is performed using a Wi-Fi hotspot created by the unit. The hotspot's name and IP address are displayed on the Network Screen of the unit when it is powered up and you can access them by using the Up or Down Arrow Buttons on the front of the unit.
Using a phone or a computer, navigate to the Wi-Fi settings on the device and connect to the hotspot name (RL-212101 in the example below). Open an internet browser and enter the IP address (10.10.10.1 in the example below) within the address bar.
The VBOX Sigma setup page is then displayed, which includes the GNSS engine status, Wi-Fi, modem, NTRIP caster settings, CAN, VBO log and status information. The serial number and firmware version of the unit is displayed on the bottom right of the page.
The top area of the setup page displays the GNSS engine status information including the latitude, longitude, GNSS fix status, RTK age in seconds, satellite count and constellations used. Selecting the Change settings button next to the GNSS heading will open a new window allowing you to change the 3rd tracked constellation between Beidou and Glonass. Use the dropdown menu to change options and press the Save button to confirm.
The Wi-Fi area of the setup page displays the VBOX Sigma unit AP name and IP address, as well as external Wi-Fi hotspot connection information. If you are intending to use an external Wi-Fi hotspot, such as a mobile phone or battery-powered hotspot to connect to the NTRIP server, this can be configured by pressing the Change settings button next to the Wi-Fi heading.
Simply enter the name and password of your hotspot and then press the Save and restart button. VBOX Sigma will then reboot and attempt to connect to the hotspot you have just configured. Once connected to the Wi-Fi hotspot, the unit will briefly display a Wi-Fi Connected message.
Note: Only a 2.4 GHz Wi-Fi signal is supported, 5 GHz is not!
To connect your phone/ PC back to VBOX Sigma, connect using the same hotspot and enter the new IP address which will be displayed at the bottom of the screen. The page will update with the new settings and provide a connection status indication. If VBOX Sigma cannot connect to the configured Wi-Fi hotspot on power, it will automatically restart and become an access point so you can configure it again.
It is also possible to change the name and IP address of the access point within this menu. If changed, the Network Display Screen will also be updated with the new access point details.
If configured, the Modem area displays the cellular access point name (APN) and connection status. If you are intending to use the internal 4G modem, ensure that the data Standard SIM card is correctly inserted within the unit and that the SIM card has been activated. The easiest way to activate it is to put it into a USB 4G dongle and go through the steps to activate it on a computer before you use it in the unit.
Press the Change settings button next to the Modem heading and then use the presented screen to configure the modem. Enter the APN, Username and Password (if required) associated with your network provider and then press the Save and restart button. Once connected to the network provider, the unit will briefly display a Connected (mobile data supplier) message.
VBOX Sigma will then reboot and attempt to connect to the internal modem you have just configured. The settings page will be updated with the new settings and provide a connection status indication. The Network Display Screen will also provide this information.
The NTRIP Caster area of the setup page displays NTRIP correction service connection information. To configure the NTRIP correction service details, press the Change settings button next to the NTRIP Caster heading.
Enter the Server Name/ IP Address, Port, Mount Point (correction data stream), Username and Password information (if required) and then press the Save button. These details will be provided by your NTRIP service provider.
VBOX Sigma will then attempt to connect to the NTRIP server using the provided details. Once connected to the NTRIP server, the unit will briefly display an RTCM Streaming message. If there is a problem with the server details entered, the unit will briefly display an Invalid Caster Credentials message.
The settings page will be updated with the new settings and provide a connection status indication along with the number of data bytes received from the NTRIP server. The Home Display Screen will also provide this information.
