This board is used to insert new signals or reroute signals coming from a headstage. It is intended for use with HS-36 headstages and provides access to all 36 signal and 4 stimulus lines. When the included jumpers are in place, the headstage signal is passed without any modification. Removing a jumper allows rerouting or elimination of a particular signal coming from the headstage or insertion of a signal from an external source. This package also includes Y jumpers that will allow signals to easily be duplicated to other channels or shared between breakout boards.
