After you've captured the required data, you can download the recorded data from your Vicon IMUs so that you can load it into Nexus.

> ✅ **Tip**   
> ✅ To help you decide whether to transfer recorded data, you can check the preview data by playing it in Offline mode first.

1. To download IMU onboard data to the current Session folder, in the ** Communications ** pane, click the **IMeasureU** tab.
  In the **Transfer** pane, a list of all the IMUs and trials available to transfer is displayed.
  For details of the options, see [Transfer pane options](#TransferPaneOptions).
2. To transfer the IMU onboard data, connect the IMU to a USB adapter and using the micro-USB cable, connect it to the PC.
  In the Transfer pane, the icons to the left of the IMUs that you plugged in are displayed in orange.
3. In the **Transfer** pane, ensure the required IMU sensor and trials are selected and to start the data transfer, select **Transfer Files**.
  The progress status is displayed when the data transfer starts.  
During data transfer, the sensor is temporarily disconnected from the Bluetooth<sup>®</sup>.  
After a trial is transferred, the progress status changes to Transfer Succeeded.
  After the transfer operation, for each trial, you can find the following files in the Session folder:
  - An .*x1d* containing the preview data (30 Hz, 50 Hz, or 100 Hz)
  - An .*imu* file containing the higher quality data (225 Hz, 1125 Hz, or 1600 Hz) from the IMU
4. You can now view and process the IMU data along with the rest of the trial data.

Transfer pane options

On the **IMeasureU** tab of the **Communications** pane, in the **Transfer** pane, you can select or remove the required trials and devices for transfer. The buttons and lists in the Transfer pane enable you to filter the displayed items so that you transfer only the items that are required

This table describes the available options.

The connection status of each sensor to the PC (via USB) is indicated by the color of the IMU symbol to the left of the sensor name in the Transfer pane:

- Orange: Connected
- Gray: Disconnected

Note that:

- If you have filtered an item from the list, it is automatically de-selected. This is to prevent accidental transfer of items that are not displayed in the list.
- Select All and Select None operate on all items that are visible in the list: an item must be visible in the list for its selection status to be updated.
- The top level sensor item is never filtered out of the list.
- The filtering is dynamic and the list refreshes when:
  - Sensors are connected or disconnected
  - Trials are captured
  - Sensors are erased
