Using m-pod With a Response Pad

m-pod is not a standalone product. It is used with StimTracker, Riponda (or earlier RB Series) response pads, or Lumina.

Here is how m-pod connects when combined with a Riponda response pad:

The response pad draws its power from your computer via USB. When a key is pressed, information is sent at the same time via USB to the computer and via m-pod to Biopac.

The combination allows four different types of signals to be delivered to AcqKnowledge:

Key press and release
Onset of a visual stimulus using a light sensor
Onset of a vocal response using any PC-compatible microphone
Event codes or markers sent via USB

This provides an excellent value if these are all the signals that you need.

When to Use m-pod With StimTracker Instead

StimTracker offers more options than the combination of response pad + m-pod described above:

Mark onset of auditory stimuli
Use more than one light sensor
Multiple outputs, e.g. one output to Biopac and one to an eye tracker, guaranteeing that your data in AcqKnowledge and in the eye tracker are on the same timebase

Additionally, with the StimTracker Quad model, you can:

Mark onset of a participant’s vocal response using a mic
Accept direct TTL and switch inputs; this is handy for custom applications such as foot pedals or accepting input from other devices
Have a direct TTL output connector, very useful when outputting to a recorder for which Cedrus does not have a ready-made m-pod model

Using m-pod with StimTracker is described on this page.
