Why doesn’t the ‘Marker Channel’ Option work in the Stimulator Dialogue with an FE180 or FE155 connected to a Front End Interface?

The ‘Marker Channel’ option in the Stimulator dialogue is not supported with the C Series. You can achieve the same functionality by enabling the analog input channel from the relevant Front End Interface in the ‘Devices and Channels’ dialog box. This channel will display essentially the same information that the ‘Marker Channel’ option would have. Alternatively, preset comments based on the Stimulus waveform can be used instead.
