Pinout Diagram
The numbers in the diagram above show the channel connections to the amplifier.
The headstage also features jumper locations to short G, R and Ref refers to the
built-in reference site on the NeuroNexus probe). The ground channel (G) should
either be tied to an external ground or to the reference (R) for a single ended
input.
Important! When using the NN64AC with the NeuroNexus Acute 64-channel probe, keep in
mind that there are several versions of the probe. Check the NeuroNexus Website for
pin diagrams. Also, see "MCMap" in the
examples on how to re-map channel numbers.
