1.3.2 Neuro board

The Neuro board is inside the E-EEG module and it consists of the following functional sections:

•

audio stimulator

•

microprocessor for stimulation and measurement control and for counting the 
measurement results

•

two serial communication drivers

The serial bus speed to the monitor is 500 kbps and the bus itself is half duplex, i.e. data can be 
transferred to both directions but only one way at a time.
The serial bus speed to the headbox is 500 kbps and the bus is full duplex i.e. data can be 
transferred to both directions at the same time.
