Operating Modes
Recording Mode
Set up all components of the Wireless-System. Start MC_Rack and add the Wireless-System as data
source. Please read chapter “Starting MC_Rack”. Define the amplifiers gain of 100 and select the
sampling frequency in the “Hardware” tab.
Make sure the storage battery is completely charged. Connect the battery to the white connector
on the headstage.
In the “Wireless” window of the MC_Rack “Hardware” tab, press the button “Scan” to find the
headstages available. After that the user is able to select the desired headstage (A, B, C, D) when
using more than one headstage. All eight recording channels are selected by default. Deselect the
channels you do not need.
The Wireless-System is in recording mode now. You can start recording by pressing the “Start”
button in MC_Rack. The storage battery allows recording of approximately two hours.
After the experiment stop the recording by pressing the “Stop” button.
The “Recording Mode” is indicated by a high frequent flashing of the blue LED on the headstage.
Stand By Mode
To save energy the Wireless-System changes from “Recording Mode” into “Stand By Mode”
immediately after stopping the recording. The “Stand By Mode” allows starting the recording
again at any time. In this mode the storage battery lasts for up to eighty days depending on the
recording time before.
The “Stand By Mode” is indicated by a very weak and slow flashing of the blue LED on the
headstage.
Switched Off Mode
To save more energy than in “Stand by Mode” you can switch the headstage off.
In the “Wireless” window of the MC_Rack “Hardware” tab, please press the button “Switch Off”
to switch off the selected headstage.
In this mode the battery lasts for up to 130 days depending on the recording time before.
Switching the headstage on from this mode is not possible via software control. To do so the user
has two possibilities: Use the infrared flasher and illuminate the receiver LEDs next to the
connector for the battery. The flasher and the headstage should have a distance of about 5 to 10
cm. The second possibility is to unplug the battery from the headstage manually and to reconnect
headstage and battery again.
Then press the button "Scan" in "Wireless Window" to reconnect to the headstage.
