The simplest way to get your RTK mosaic-X5 up and running is to connect it to your Ethernet network or an Ethernet port on your broadband router:
1- Connect the GNSS antenna-
- Inside your RTK mosaic-X5 kit, you will find the L1/L2/L5 GNSS "UFO" antenna. It has a TNC connection. Use the supplied TNC-SMA cable to connect the antenna to the mosaic-X5 MOSAIC SMA connection.
- The antenna needs a clear view of the sky. If you are working indoors, put the antenna outside and pass the cable through a window. (Insulating double-glazed windows have a coating which can block the GNSS signal. For best results, put the antenna outside.)
- If you are going to use your RTK mosaic-X5 as an RTK Base, the antenna needs to be securely mounted to a structure so that it cannot be moved and has a clear view of the sky. Any movement in the antenna will cause inaccurate readings by RTK rovers. Please see the Required Materials for links to our GNSS Antenna Mounting Hardware Kit and GNSS Magnetic Antenna Mount - 5/8" 11-TPI
2- Connect the RTK mosaic-X5 to your Ethernet network or router-
- Use the supplied CAT-6 Ethernet cable to connect the MOSAIC ETHERNET (PoE) port to your network or an Ethernet port on your router.
- If your router provides Power-over-Ethernet (PoE), you're all set! You should see the red power (PWR) LED light up and text start to scroll up the OLED display.
- If your router does not provide PoE, move on to step 3.
3- Provide power-
- You can power the RTK mosaic-X5 using the supplied USB power supply (5V 1A wall adapter).
- Plug the power supply into the wall.
- Use the supplied USB-C cable to connect the power supply to either the CONFIG MOSAIC or the CONFIG ESP32 USB-C port. It does not matter which.
- You should see the red power (PWR) LED light up and text start to scroll up the OLED display.
Once the mosaic-X5 has acquired a satellite signal and is connected to the Ethernet network, the OLED will display: the antenna's position as Latitude (Lat), Longitude (Long) and Altitude (Alt); the Ethernet IP (Internet Protocol) network address.
Connect your computer, tablet or phone to the same network, open a web browser and navigate to the IP address shown on the OLED display. You should see the mosaic-X5's internal web page. The web page displays a lot of helpful information and can also be used to fully configure the mosaic-X5.
Not working?
The following sections will help if your RTK mosaic-X5 is not working as expected:
No power?
The red power (PWR) LED will light up when the RTK mosaic-X5 has power. If the PWR LED is off, make sure the wall adapter has power and the USB cable is connected.
If you use your own Ethernet cable for Power-over-Ethernet, check it has all eight pins connected. Some cables only have four pins connected and do not support Power-over-Ethernet.
No position information?
The OLED display will only show position information (Lat, Long, Alt etc.) once a satellite signal has been acquired. If you see only the IP address on the display, check the SMA to TNC cable is connected correctly and that the antenna is outside with a clear view of the sky. Use a male-female SMA extension cable if needed to increase the cable length.
No IP address?
By default, the mosaic-X5 Ethernet port is configured for Dynamic Host Configuration Protocol (DHCP). It expects the router / Ethernet switch to provide it with an IP address. If the IP address is all zeros (0.0.0.0), check that your router has DHCP enabled. Most do.
If you need a static IP address, you can configure this through the mosaic-X5's Communication Ethernet sub-page.
Subnet 3 is reserved for the mosaic-X5's USB-C connection (Ethernet-over-USB). If your router / switch is allocating addresses using subnet 3 (192.168.3.***), please change its settings so it uses a different subnet.
No web page?
If you can not see the mosaic-X5's internal web page, please check that your computer / tablet / phone is connected to the same network. Most broadband routers support both Ethernet and WiFi simultaneously using the same subnet. If you are using a phone, check it is connected to the router WiFi - and not using its mobile data connection.
Subnet 3 is reserved for the mosaic-X5's USB-C connection (Ethernet-over-USB). If your router / switch is allocating addresses using subnet 3 (192.168.3.***), please change its settings so it uses a different subnet. If it is using subnet 3, both the mosaic-X5 and your device will appear to have valid IP addresses but will not be able to communicate.
Wrong mode?
If you still can not see the mosaic-X5's internal web page, please check that the ESP32 firmware is in the correct mode. Press the RESET button to restart the ESP32 and watch the text, which scrolls up the OLED display. You should see Mode 1: Ethernet displayed briefly. If you see Mode 2: WiFi, the firmware is in the wrong mode. Follow the instructions in the next section to change the mode back to 1 (Ethernet).
The mosaic-X5 GNSS module supports multiple communication interfaces: multiple UARTs; Ethernet; and USB-C (with Ethernet-over-USB). But it does not support WiFi directly. The RTK mosaic-X5 contains an ESP32-WROVER processor which can act as an Ethernet to WiFi bridge. By linking the MOSAIC ETHERNET (PoE) port to the ESP32 ETHERNET port and putting the ESP32 firmware into WiFi mode, the mosaic-X5 can join your WiFi network.
To connect your RTK mosaic-X5 to WiFi, you need to do a little more work including changing the mode of the firmware running on the ESP32 processor.
1- Connect the GNSS antenna-
- Inside your RTK mosaic-X5 kit, you will find the L1/L2/L5 GNSS "UFO" antenna. It has a TNC connection. Use the supplied TNC-SMA cable to connect the antenna to the mosaic-X5 MOSAIC SMA connection.
- The antenna needs a clear view of the sky. If you are working indoors, put the antenna outside and pass the cable through a window. (Insulating double-glazed windows have a coating, which can block the GNSS signal. For best results, put the antenna outside.)
- If you are going to use your RTK mosaic-X5 as an RTK Base, the antenna needs to be securely mounted to a structure so that it cannot be moved and has a clear view of the sky. Any movement in the antenna will cause inaccurate readings by RTK rovers. Please see the Required Materials for links to our GNSS Antenna Mounting Hardware Kit and GNSS Magnetic Antenna Mount - 5/8" 11-TPI
2- Attach the WiFi antenna-
- Screw the supplied WiFi/BT antenna onto the ESP32 SMA connection.
- To minimize wear of the SMA connector, we recommend: holding the antenna body with one hand - to prevent it from rotating - while screwing the SMA connector into place with your other hand.
- Fold the antenna up if needed, so the antenna body is vertical.
3- Link the Ethernet ports-
- Link the MOSAIC ETHERNET (PoE) and ESP32 ETHERNET ports using the supplied cable.
- The Ethernet ports support Auto-MDIX. You can use a standard Ethernet patch cable to link the ports. You do not need a crossover cable.
4- Connect to the CONFIG ESP32 USB port-
- To change the ESP32 firmware mode, you need to connect a computer to the CONFIG ESP32 USB-C port and use a Serial Terminal to change the mode.
- You may need to install a driver, first, so that the CH340 serial interface chip is recognized. Please click the bar below for more details.
WiFi Mode (PNG) for the RTK mosaic-X5. Install CH340 Driver
Users may need to install the appropriate USB driver for their computer to recognize the serial-to-UART chip on their board/adapter. Most of the latest operating systems will recognize the CH340C chip on the board and automatically install the required driver. To manually install the CH340 driver on their computer, users can download it from the WCH website.
