Hi,

we recently had our two BioSemi ActiveTwo systems upgraded with ABR electrodes and a new ABR connector on the AD-box front panel. The new electrodes register as H7 and H8 in ActiView. When switching to 16kHz sampling rate all higher numbered electrodes are greyed out and it seems impossible to record from the ABR electrodes without some kind of channel remapping.

Is it possible to remap the AD channels in the software to get our ABR electrodes into the first 32 channels so we can use the higher sampling rates?

Best wishes,
Marc

The ABR electrodes only work with a special acquisition program (ActiABR), you can download it here: http://www.biosemi.com/download/ActiABR-100.zip (also on the CD that came with the ABR upgrade)

You will have to switch the AD-box to speedmode 9 in order to use the ABR electrodes and ActiABR software.

Best regards, Coen (BioSemi)

Thanks Coen! We did not receive a CD or any further explanation from the north-american distributor (Cortech).
