General.

The BRAINBOX® ETHERNET SYSTEM is intended for all sorts of EEG investigations and sleep recordings. Offering both very small size for ultra portability and larger types for operator convenience.

The BRAINBOX® EEG-1042 amplifier is ergonomically designed for stationary use in routine EEG and Sleep analysis. It features a standard commonly used layout of Touchproof connectors integrated in the case. The EEG-1042 has a display with an LED for each electrode for measurement of the electrode impedance. When an electrode placement needs correction so there is no need to walk to the PC to see if it is OK. The override button on the amplifier to select the impedance check mode and level further enhances this feature. The EEG-1042 amplifier has a BRAINNET socket for a Braintronics Photic Stimulator or to expand the system by adding other BRAINBOX® Devices. As an example, adding an ISO-101 Isolator with EEG-1166 gives a system with 96 EEG channels, 8 DC channels, SpO2 and Event, 8 digital inputs and 8 digital outputs. The flexibility of the BRAINBOX® system makes many other configurations possible.

Electrode connections:
For quick and easy connection of Electrode Caps, all amplifiers are equipped with multipin connectors.

For the connection of electrodes with standard Touchproof Plugs, the EEG-1042 amplifiers has 54 Touch Proof inputs for EEG, DC, G1/G2 and Ground Reference on the front of the amplifier.

Isolation:
The isolation function is integrated in the EEG-1042 amplifiers.

Interface connection of BRAINBOX® :
The BRAINBOX® device is connected to the BRAINNET connection on the ETHERNET-102 (V2) interface. The optional FLASH-201 stimulator can be plugged in into the remaining BRAINNET connector on the ETHERNET-102 (V2) or on the BRAINNET connector of the EEG-1042 amplifier. (see system configuration)

Network Interface:
The BRAINBOX® ETHERNET SYSTEM communicates with the PC by means of the ETHERNET-102 (V2) INTERFACE that connects to a standard 10/100 network port on a PC. The third party EEG-analysis software is responsible for proper implementation of the used control protocol, acquisition and analysis. Interfacing is described in document: BRAINBOX® Software Protocol V1.0. The PC software controls Calibration, Electrode Check, etc. of the amplifier over the same thin cable as the digitized EEG signals are transmitted. Power for the amplifier(s) is also supplied over this interface cable.
