BioChip not properly initialized
Symptoms
On the MEA Viewer control in BrainWave, large red horizontal stripes move up or down across the entire
array.
Causes
BioChip are monolithic CMOS-MEA chips integrating active semiconductor components (i.e. transistors)
underneath and around the active area (i.e. the area exposing the sensing surface of the electrodes).
Some of these active components need to be correctly biased by sending configuration settings from
BrainWave to the BioCam and the BioChip before starting the read out of the data. This operation is
performed when starting the acquisition in BrainWave (e.g.by clicking Play or Record buttons). If the con -
nection to the BioChip is not in place or it is compromised, the initialization of the chip will fail.
Possible scenarios and remedies
# Scenario Remedy
S6 BioCAM locking system (see section “Plug
the BioChip” ) was in the unlocked state when
acquisition was initiated.
Stop the acquisition, make sure that the Bio -
Chip is properly inserted till the end of its bay
and push the Lock button of the BioCAM X to
its end position (see section
“Plug the BioChip”
for more details). Make sure that the BioChip
LED icon on the BrainWave’s Right Status Bar
(see section
“BrainWave X” ) is on, signalling that
the BioChip is properly inserted and locked.
Restart the acquisition.
If the BioChip LED icon on BrainWave does not
turn on, see following scenarios.
