m-pod for actiCHamp plugs directly into the 9-pin Trigger In connector on the back of your actiCHamp amplifier. This document describes the signals that m-pod makes available to actiCHamp.
You do not really need to do anything in Recorder in order to see event makers. They are displayed at the bottom of the screen, e.g. S32, S64, and so forth:
However, you may find that adjusting some settings can make your data analysis easier later on. To do so, click on the Amplifier menu and choose Digital Port Settings…. Recorder displays the following dialog:
In the table, click on the “Type” column of the relevant row to rename, e.g. rename “Stimulus” to “Light sensor”. Recorder will then display an “L” prefix instead of “S” when it detects a light sensor event marker. See Recorder’s manual for more information.
The leftmost column shows the bit numbers as seen by BrainVision Recorder:

m-pod contains a powerful microprocessor that can reassign any input signal to any output line, and without any significant delay. It can also assign multiple signals to the same output line.
The tables above describe the factory default. If your experiment or lab setup requires different output, Cedrus provides a free utility for configuring your m-pod. After you use it, your configuration is saved to flash memory so that it’s remembered even after you power off m-pod.
