Are all channels of the EEG-ANALOG-ASM board compatible with both passive and active electrodes?
DRL needs to be passive always.
IMPORTANT: The electrodes OLIMEX sells (both AE and PE) are not compatible with EEG-ANALOG-ASM!!! These electrodes are compatible only with EEG-SMT! You have to make own electrodes for the EEG-ANALOG-ASM board. Information how to do it might be found here: http://openeeg.sourceforge.net/doc/hw/electrodes/ (http://openeeg.sourceforge.net/doc/hw/electrodes/).
