Overview

Important: Read Before Use!

ESD Sensitivity

The mosaic-X5 module is sensitive to ESD. Use a proper grounding system to make sure that the working surface and the components are at the same electric potential.

ESD Precaution

As recommended by the manufacturer, we highly recommend that users take the necessary precautions to avoid damaging their module.

  • The Tri-band GNSS RTK breakout board features ESD protection on the USB-C connector and breakout's I/O:
    • USB data lines
    • I/O PTH pads
    • JST connector's pins
  • The mosaic-X5 module features internal ESD protection to the ANT_1 antenna input.

Note

The mosaic-X5 module has numerous capabilities and a multitude of ways to configure and interface with them. Without regurgitating all the information that is documented in Septentrio's user manuals and videos, we have tried to highlight a good majority of the module's aspects.

With that said, please feel free to file an issue if you feel we have missed something that may benefit other users. (Don't forget to provide us with a link to the documentation and what section the information is located.)

RxTools Software Suite

Tip

Even if you aren't necessarily interested it, we highly recommend that users install the RXTools software suite before plugging in their board. For Windows PCs, it also includes the USB driver for the module that enables the Ethernet-over-USB support and virtual COM ports.

Users should install the RXTools software suite on their computer to interact with the mosaic-X5 module through the USB interface. The software package includes the USB-IP driver1 necessary to recognize the board as an ethernet device on Windows PCs (1).

  1. On Linux, the standard Linux CDC-ACM driver is suitable.

Download the RxTools Software from Septentrio

System Requirements2
  • Windows 7
  • Windows 8
  • Windows 10
  • Fedora 23 (or later) using Qt technology.
    • The standalone tools (except bin2asc) will run on older distributions.

The minimal hardware requirements (1Hz update3):

  • CPU: 1 GHz processor
  • RAM: 1 GB RAM
  • Screen Resolution: 1024×768 or higher resolution
Installation Instructions2

Users can install RxTools software suite by running the installation executable4(1), located in the RxTools\windows directory of the downloaded *.zip file5. During the installation process, users will be notified if a previous version of RxTools is already installed then that the previous version will be uninstalled. Next, users will need to provide an installation directory for the RxTools software suite. Users will then select which of the following applications6 are installed:

  1. For RxTools v22.1.0, the installation filename is RxTools_22_1_0_Installer.exe for Windows PCs.
  • RxControl
  • SBF Converter
  • SBF Analyzer
  • RxLogger
  • RxUpgrade
  • RxDownload
  • RxPlanner
  • Data Link
  • RxAssistant
  • RxLauncher

Warning

It is recommended that users NOT install RxControl as root, for security reasons and to avoid installation overwrites of other system settings. To make RxTools available to more than one user, provide a shared installation directory.

Users can install RxTools software suite by running the installation binary4(1), located in the RxTools/linux-i386/ directory of the downloaded *.zip file5. During the installation, users will be prompted for an installation directory. If there are any previous installations of RxControl, please use a different directory to avoid conflicts.

  1. For RxTools v22.1.0, the installation filename is RxTools_22_1_0_Installer.bin for Linux.
Permission Settings

Once installed, users may need to reconfigure their permission settings:

  • RxTools will need rights to access the /dev/ttyS* serial ports.

    • To access the serial ports, users must be part of the uucp and lock groups (1). This can be configured by editing the /etc/group7 file and adding the username to the lines defining the uucp group and the lock group.

      For example, when adding the user jsmith to the uucp group, users would modify the /etc/group file as shown below:

      uucp:x:14:uucp # (2)!
uucp:x:14:uucp,jsmith # (3)!

    • On Linux machine administered centrally on a local network, ask your system administrator to be included in the uucp and lock groups.

  • RxTools also needs read/write (rw) access(4) to the /dev/ttyS* serial ports.

    • Users can change the permissions with the chmod8 command:

      chmod 660 /dev/ttyS<add port> # (5)!>
  1. On most Linux operating systems, the /dev/ttyS* devices are owned by root and belong to the uucp group with read/write (rw) access. Additionally, the devices are normally locked by writing a file in the /var/lock/ directory, with the same permissions.
  2. Remove
  3. Replace with this line
  4. By default, users will normally have read/write (rw) access to the /dev/ttyS* serial ports.
  5. where users must specify the port number
    e.g. /dev/ttyS0 might be port COM1

Note

In order for these changes to take effect, users must update their environment by logging out and back in.

Be aware that the X-session has to be restarted as well. On most systems, this can be done by pressing the key combination Ctrl + Alt + Backspace

64-bit OS

In order to run the RxTools on a 64-bit Linux operating system, users might to install the 32-bit version of the C standard library.

  • For Fedora installations, this is the glibc.i686 package.
  • The equivalent for Debian(/Ubuntu) installations is the ia32-libs package.

USB Driver

If users haven't already installed the RxTools software suite on their Windows PC, they will need to install the USB driver1 necessary to recognize and interact with the mosaic-X5 module through the USB interface.

A Windows USB driver for the mosaic-X5 can be installed through two methods:

  • RxTools Software Suite (1)
  • mosaic-X5 GNSS Receiver Module (2)
  1. The driver is installed during the installation process.
  2. The installation file for the Windows USB driver will be available from the mass-storage device when the board is initially connected to the computer.

Once installed, the driver emulates two virtual serial ports, which can be accessed as standard COM ports to the receiver.

Terminal Emulators

Most terminal emulation programs will not make a distinction between virtual or native COM ports. However, for virtual serial ports, the port settings (i.e. baudrate, etc.) are not relevant and the default configuration be used in the terminal emulation program. However, for the physical/native COM ports will have the following default setting:

  • Baudrate: 115200bps
  • Data Bits: 8
  • Parity: No
  • Stop Bits: 1
  • Flow Control: None
Having Trouble?

For users who are having trouble installing the USB driver, we have an archived version (v3.0.29) of the installation file. Users can download version 3.0.2 of the driver, by clicking on the button below.

Download USB Driver (v3.0.2)

On Linux, the standard Linux CDC-ACM driver is suitable.

Web Interface

With the USB driver installed, the mosaic-X5 module supports Ethernet-over-USB. The default IP address allocated for the Ethernet-over-USB interface is 192.168.3.1. This IP can be entered in any browser to open a connection to the receiver's Web Interface as shown below.

navigation tabs in the web interface

All the drop-down navigation tabs in the web interface.

Info

The default IP address cannot be changed; this feature is only to be used when a single receiver is connected to your computer.

Invalid IP Address (WiFi Only)

One of the documentation pages on Septentrio's website, specifies a default IP address of 192.168.20.1 for the web interface. However, that address is for a WiFi enabled product and cannot be used with this product.
