Configure with RxTools

  • EVK:
  • Facet mosaic:
  • Postcard:
  • Torch:

On the RTK Facet mosaic, it is possible to configure the mosaic-X5 GNSS module using Septentrio's RxTools: GNSS receiver control and analysis software.

However, because the ESP32 does considerable configuration of the mosaic-X5 and the Boot and Current receiver configurations at power on, you need to use a little care when modifying the settings of the X5 using RxTools. Nothing will break, but your changes could be overwritten at the next power cycle or if you Factory Reset the settings.

We have only used RxTools on Windows, but it is also Linux compatible.

Download and install RxTools before continuing. This will also install the USB drivers needed to communicate with the mosaic-X5.

There are multiple ways to connect to the mosaic-X5 using RxTools:

  • While the RTF Facet mosaic is connected to your computer via USB, two additional serial COM ports will appear in Device Manager: Septentrio Virtual USB COM Port 1 and 2. RxTools can be configured to use either serial port. The X5 firmware names these ports USB1 and USB2.
  • The mosaic-X5 also supports Ethernet-Over-USB and can be configured via TCP/IP. In RxControl / Change Connection, select TCP/IP Connection and enter 192.168.3.1 as the Receiver Address.
  • The RTK Facet mosaic DATA JST connector is connected the mosaic-X5 COM3 UART port via a multiplexer. Please see Ports Menu for more details, and the section on the Mux Channel in particular. Set the multiplexer to GNSS TX Out/RX In to connect X5 COM3 to the DATA port. The baud rate can be changed through the menu; the default baud rate is 230400 (8 data bits, no parity, 1 stop bit). To connect the DATA port to your computer, you will need a Serial Basic Breakout or similar.

If you want to save the X5 configuration after you have changed it, we recommend using either of the User1 or User2 Receiver Configurations. The RTK Everywhere firmware will modify the Current and Boot Receiver Configurations, but it leaves User1 and User2 for your use. Copy the Current configuration into (e.g.) User1 to save the modified configuration. You can restore it later by copying User1 into Current. See Custom Configuration for more details.

RxTools is very powerful software. It can read, analyze and visualise log files containing both NMEA and SBF binary data. It can also convert data to other formats. The mosaic-X5 supports data logging in RINEX format directly. But it is also possible to log data in SBF binary format and later convert it to RINEX using RxTools.
