  1. Introduction

Specifications

The EMOTIV Extender is compatible with our latest headsets (Insight, Flex and EPOC+) and is designed to enhance the headset usability by providing longer battery life and data storage. It has four functions:

  1. Extends the battery life of the headset.

  2. Allows tethering of the headset to your computer. The tether is isolated to provide a safe, reliable connection while minimising the injected noise.

  3. Allows a user to record their sessions to a microSD card for later playback and analysis, removing the need to record to a mobile device or PC.

  4. Allows an external hardware trigger to inject marker data directly into the raw data stream, improving accuracy of marked events to +/- 1 sample.
