How To


If your Optima was purchased from Brain-Trainer you should have an amplifier or Neurobit setup file. Check your Brain-Trainer account. When this setup file is run, necessary files should be in place.

Neurobit FTDI chip Driver Installation

This will install the Future Technology Devices International chip driver which is not part of the Neurobit setup. If the Optima+ fails to install correctly this driver may be missing.

  1. Turn off antivirus program and firewall
  2. Go to FTDI Chip site and scroll down to D2XX Drivers. Download the driver for your system (likely D2XX Driver Windows 64-bit setup executable v2.12.36.2) CMD212362_Setup.  Extract and right-click and run as administrator. [installation guide]

Infra-Low Frequencies (ILF)

It is possible to train low frequencies with the Optima, as long as they are higher than 0.01 Hz. A protocol that has been working particularly well for one trainer is FRE%1C set to the 0-0.1 Hz range.

Independent References with Electro-Cap

With “Cap enable” selected on EEG Cap tab in Neurobit Optima+ settings, “Common reference” will switch to “Internal connection” and become inactive. Ear clips connected to the caps drop wires are automatically linked and cannot be unlinked. To allow independent references, do the following:

1) Connect long tin ear clip electrodes to the ear lobes and to the Optima’s A- and B- connection ports.

2) Load from Documents\Neurobit the settings file EEG 4C (I) Independent.nbc
