Setting Up Your XB122 + XM126

To evaluate the XM126 module, it is recommended to connect it to an XB122 break-out board to access different pins. A Micro USB cable (not provided by Acconeer) is needed to connect the XB122 board to a PC.

Hardware Overview

Finding the Serial Port

In preparation for connecting and flashing, it is good to know the serial port of the device.

Windows Linux

Use Device Manager to find the port. It is listed under Ports (COM & LPT) as USB Serial Port or Enhanced COM Port. It’s most likely COMx where x is 3 or higher.

PySerial has a simple tool for listing all ports available:

python -m serial.tools.list_ports

Windows COM Port Drivers

If no COM port is recognized when plugging in a module, you need to install a driver:

• XM126: FTDI

On the page from the link above, go through the following steps to install the driver:

• Select Windows (Desktop)

• Click on setup executable

• Extract the downloaded file

• Click on the extracted .exe file

• Follow the installation instructions

Flashing

The most convenient method to prepare the XM126 board for flashing is to let the Exploration Tool Application automatically download the latest binary file from our developer page. If you want to flash a binary that you have locally on your computer; that is also possible.

Depending on how you installed in Exploration Tool Installation, start Exploration Tool by either

• Double-clicking the run_app script,

• Running the command python -m acconeer.exptool.app in your terminal.

Then get started by pressing the Flash button in Exploration Tool and you will be guided through the flashing process.
