Stimulation without blanking
Usually, you will always use the blanking when you stimulate. But it is possible to switch off
the blanking for testing your setup.
1. In MC_Rack, bring the triggered display to the front. Make sure you have connected the digital
Sync Out output of the stimulus generator to the digital channel 1 (bit 0) of the MC_Card.
Otherwise, you have to select the appropriate bit in the Trigger Detector.
2. In MEA_Select, under Blanking, deselect Blanking.
3. Under Stimulation, select the appropriate stimulus input (Stim A or Stim B).
4. Click any electrode that you like to use for stimulation, for example 53. The stimulation electrodes
are marked by a color, that is, blue for stimulus A and red for stimulus B. By clicking on one of
the selected electrodes again you can toggle back to recording mode. If you click, for example in
Stimulation mode B onto a blue (Stim. A) or grounded electrode, you overwrite the mode with
Stim. B mode. That means, the color will turn to red and the number of the grounded electrode
appears again. If you click for the third time, the selected electrode toggles back to recording
(= default) mode.
