c-pod for NIRx

Setup

“c-pod for NIRx” delivers 8 bits of external triggers to your NIRx recorder. Depending on the model, 4 or 8 bits will be recorded. c-pod connects to an adapter cable that is included with every NIRx recorder. The other side of this adapter cable plugs into the trigger connector on the NIRx recorder, highlighted in blue in the pictures below. Click on any of them to zoom:

The other side of c-pod connects to the computer’s USB port (cable included).

Setting Up the Software

On the stimulus presentation side, using c-pod requires the installation of a USB driver. See the main support page for the links.

No particular setup is necessary on the NIRx side. The NIRStar software is always looking for trigger input and displays that information in its main window. The screenshot below shows an event marker on every other input line:
