‍Summary

‍m-pod can send event markers to Blackrock NeuroPort via the “DIGITAL INPUTS” connector (number 4 in the picture). You need:

• m-pod for Biosemi
• DB37 female-female gender changer

‍In addition to NeuroPort, this support note also applies to Blackrock Neurotech’s CerePlex Direct and Cerebus systems as they have the same DIGITAL INPUTS connector.

‍Setup

‍On the Hardware Configuration screen of Central, the Blackrock Neurotech software:

• Select Signal Types Digital In to view a list of input channels.
• In the list, right-click on a channel of interest and select Properties.

‍In the Digital Input Properties dialog, select the option “16-bit on bit changes”.

‍Available Signals and Lines

‍The DIGITAL INPUTS connector on NeuroPort has 37 pins and accepts 16 lines of input. m-pod for Biosemi uses the same connector and offers 16 lines of output, 15 of which align nicely with the input lines on the NeuroPort. This leaves one m-pod output line that cannot be used with NeuroPort: line 0 is not available.

• When m-pod is connected to a Riponda or RB-x40 response pad, line 0 corresponds to button 1. 
• When m-pod is connected to a StimTracker Quad, line 0 corresponds to light sensor 4.

‍We highly recommend that you adjust the signal mapping so that no signals are assigned to output line 0.
