- Choose the ‘Configuration’ tab and the window as shown above will appear.
- Select BrainAccess as source.
- Press ‘Scan for devices’ and after a while all BrainAccess devices that are paired to the computer will appear on the list.
- Select the device that you wish to connect to.
- Press ‘Connect’ and the device should appear under the ‘Connected Devices’ list. The data is now being streamed to the computer.
- Press the ‘graph button’ on the listed device which will open an EEG viewer and allow you to check the EEG and/or other sensor signals.

Changing Advanced Settings
Expand the ‘Advanced’ settings section if you wish to configure the device or other parameters. These settings are pre-populated with default parameters and could only be changed before connecting to the device.
EEG channel labels, gain and on/off state could be changed as required. In addition, the data stream to Lab Streaming Layer (LSL) can be enabled (default) / disabled here. The COM port that the particular device is paired to is also shown here, which helps identifying a particular BrainAccess device if multiple devices are used.
Data Recording
The stream can be saved to the database, enter required details in the ‘Data Recorder’ section and press ‘Start recording’. The data streams from all the listed devices will be collected and saved to the file. The data is saved in an internal format, which could be later converted to standard EEG formats such as EEGlab, MNE_fiff, etc. using ‘File Converter’ App.
