NN32AC-Z Tech Notes

32 channel NeuroNexus compatible headstage pinout correction

TN0945

Product: NN32AC, NN32AC-Z
Version: NN32AC-Z SN 2000-2030, NN32AC SN 2000-2010
Date Added: 2014-11-11

Issue

The TDT NN32AC NN32AC-Z headstage (serial numbers >2000) were changed to match rev3 of the NeuroNexus 32-channel acute probe. At that time a miswiring occurred, such that channels 30 and 31 swapped positions.

Serial number > 2000 (designed for Rev 3 probe)

AS INTENDED

AS DELIVERED

Workaround

You can correct the channel numbering by adding the mapping segment linked from this page to your circuit in RPVdsEx:

See the linked circuit for DataTable values.

Note

The NeuroNexus 32-channel acute probe has undergone several revisions, always verify the correct pinouts for your probe and headstage.

Solution

Beginning with the NN32AC serial number 2011 and the NN32AC-Z serial number 2031, the miswiring has been corrected. Contact TDT if you have any trouble implementing the workaround.
