4.2 Toggling Channels
Each channel of the data stream is either assigned to the left or the right MEA. You cannot select
the same channel from both MEAs.
The buttons represent single channels and have a toggle function. Click a button to activate
or deactivate a channel. Acitvated means, the channels are detected in MC_Rack. Non-selected
channels appear in grey. If you have a 128-channel MC_Card or an USB-ME128-System, you can
configure the channel layout for two pairs of MEAs separately.
The MEA S4/2 does not replace a Signal Grounding unit. That means, the channels that are not
selected are only removed from the input data stream, but they are not grounded. If you have
bad electrodes that produce noise, the noise can still interfere with your input signals.
1. Click a button to select a single channel or click All to select all channels. A selected channel
button appears in green color. The corresponding channel on the other pair is deselected and
colored in red.
2. Click a selected channel again to deselect it. The corresponding channel on the other
pair is selected and colored in green.
3. Non-selected channels appear in grey.
