What's in the box
- Emotiv EPOC neuroheadset (FCC ID: XUE-EPOC01)
- USB wireless receiver dongle (FCC ID: XUE-USBD01)
- Hydrator w/ 16 saline sensors inside (note: not all batches have included the hydrator and have instead had the sensors already attached to the headset)
- AC Adapter to USB (mini-B) power adapter or USB cable
- Bottle(s) of saline solution
- CD containing a copy of the ordered SDK or software sets
The USB port included on the headset is strictly for charging use. Attempting to extend battery life by connecting power to the device while on will cause the device to enter standby mode. While charging, the charging LED will be RED. After the headset has fully charged the charging led will turn GREEN.
The EPOC electrodes are modular allowing for easy replacement for alternative or replacement sensor modules. While the device is set to initially start shipping with only saline sensor modules, dry sensor modules are expected to be available at some point.
Making your own saline solution
see Making your own saline solution, probably should be worked into a saline sensor specific section rather than a 'making your own saline solution section'
All incoming data from the headset is encrypted and must be first decrypted by edk.dll or another Emotiv application. Additionally, the premium version of edk.dll issued to SDKs with raw data access will be license limited to disallow raw data output as an output of edk.dll using programs.
Differences between SDK and Consumer headsets
In most details the two will be physically identical. There will be a firmware difference between the SDK version and the Consumer version and some minor labeling differences. The SDK version will work will all applications, while the Consumer version will be locked out of all but statically compiled (and therefore pre-screened) applications.
For SDK in linux you must download the attachment file in the oficial page, step by step is: www.emotiv.com->login->MY EMOTIV-> MY DOWNLOADS -> Research Edition - Linux// this downloaded a .sh file, exeute this file an start the SDK
Allows viewing and saving of raw EEG streams from compatible headsets. Files saved from TestBench are EDF files. A few example output files from the software can be downloaded here.
