Nexus 2.10 and later enables you to stream live data from your Vicon IMUs so that you can visualize the outputs in real time.

You can use any of the data channels from the IMU:

- HighG accelerometer
- LowG accelerometer
- Gyroscope
- Magnetometer
- Global angle (angle-axis from the onboard 9-axis quaternions)

**To stream live data from Vicon IMUs:**

1. Ensure the required IMUs are connected (see [Connect Vicon IMUs to Nexus](https://vicon-help.atlassian.net/wiki/spaces/Nexus220/pages/897713445/Configure+Vicon+IMUs#ConnectIMUs)).  
All the available axes automatically stream data:
  - LowG accelerometer (16 G) (x, y, z)
  - Gyroscope (x, y, z)
  - Magnetometer (x, y, z)
  - Global Angle (x, y, z)
  - HighG accelerometer (200 G) (x, y, z)
    The default stream rate is 50 Hz, but can be 30 Hz, 50 Hz or 100 Hz. While the IMUs are connected to Nexus, a real-time preview of data streaming from the IMUs is displayed (when Nexus is in Live mode). This preview data stream is supplied to Nexus at the selected stream rate, regardless of the trial collection rate (225 Hz, 1125 Hz or 1600 Hz). The preview stream is optimized for low latency data visibility and may therefore have small frame gaps where data does not appear.
2. To change the stream rate, select an IMU on the **System** tab, and in the **General** section of the **Properties**, click in the **Stream Rate** field to change its value.
  Note that the stream rate that you specify, together with the number of connected IMUs, affects performance.

 Select the required axes

By default, all axes are enabled.

To select the required output, you choose from a list of presets.

**To select the output axes:**

1. In the **System** tree, select the required IMU.
2. In the **Properties** pane, click the **Output Preset** menu.
3. From the list, select the required option:

> Macro (scroll-pagebreak)

In addition to selecting the output from the Output Preset list, you can select or clear **Enabled** in the Properties for the axes, to customize the output.

> ⚠️ **Note**  
> ⚠️ If you plan to capture global angles, first [calibrate the IMUs](https://vicon-help.atlassian.net/wiki/spaces/Nexus220/pages/897714380).

    **To deactivate an axis:**


1. On the **System** tab, select the required IMU and expand its node.
2. To deactivate an axis, click on the required axis and in its Properties, clear the **Enabled** check box.
  On the System tab, the color of the cleared axis changes from green to orange and the Graph displays null results for that axis.
  If **Global Angle** is deactivated, the coordinate system for the relevant sensor is no longer displayed in the 3D Perspective view.

### Use IMU streamed data with the Vicon DataStream SDK

All Vicon IMU data can be passed to the Vicon DataStream.

For example (using C++):
