5 Connecting the NeuroNexus Probe
Insert one pin array of the NeuroNexus Probe adapter into one MPA8I, and the other into
the second MPA8I. Make sure that the orientation of the MPA8I is correct (see illustration).
Channel assignment, output pins.
Shown are the output pins of the adapter that are connected to the miniature preamplifiers MPAI
when looking directly at the pins. The numbered channels are the ground channels (G), the
reference channel (R), and the 8 recording channels (1 - 8) of the MPA8I.
Channel assignment, input pins.
Shown are the input pins of the adapter that are connected to the probe. The labelled channels
are the ground channel (G), the reference channel (R), and the 8 recording channels (1 - 8) of the
MPA8I. G and R have been connected together as factory-default settings. You can change this
connection to meet your requirements.
Important: Operation of the MPA8I is differential.
The reference channel R has to be used for obtaining
a proper signal.
