7.1 Technical Specifications
7.1.1 Pin and MEA Layout
The layout of standard MEA electrodes follows the scheme of a standard grid: The first digit
is the column number, and the second digit is the row number. For example, electrode 23
is positioned in the third row of the second column. The numbering follows the standard
order from left to right, and from top to bottom.
MEAs are not symmetrical, please pay attention to the recommended orientation
of the MEA chip inside the amplifier: The writing NMI should be on the right side.
The illustration shows the standard pin layout of the socket on the amplifier.
The list below shows the assignment of the electrodes to the pins of the socket.
Pin 1 is the ground of the power supply, pin 2 is the ground of the signal, that is,
where the signal is referred to. Both pins are already internally connected inside
the amplifier.
Channels A1 to A4 are the four additional analog inputs of the MC_Card that are
not used by the MEA amplifier. You can access channels A1 to A3 via the BNC sockets
labeled Analog IN on the rear side of the data acquisition computer of the MEA-System
(see also MEA-System Manual).
