o 68 µs delay between single stimulations
o 76 µs delay between the end of a stimulus and the beginning of a group
o 68 µs delay between the end of a group and the beginning of another stimulus
o 116 µs delay between the end of a group and the beginning of another group.
Repetition Panel: This feature allows the user to repeat the Stimulation Script a specified number
of times, or to run it as a continuous loop. Without a defined number of repetitions, the CereStim
R96 defaults to a single pass of the Stimulation Script. In a continuous loop, the CereStim R96
requires a manual stop in order to end stimulation.
Start: Once Pre-Process has been completed, the system is ready to stimulate. Stimulation is
initiated by clicking the Start button.
Pause: Clicking this button immediately pauses the Stimulation Script. To resume stimulation from
the same point in the Script, click the Start button.
Stop: Clicking this button manually stops the stimulation. It is not possible to modify any
parameter during stimulation. The user must stop the stimulation sequence prior to making any
changes to the Stimulation Script or Pulse configurations. After making changes, the Pre-Process
button must be pressed again in order to update the changes to the CereStim R96.
Output Vmax Panel (9): This feature allows the user to select the maximum analog output voltage as a
safety measure for stimulation. Users should be cautious when making changes to the Output Vmax. A low
Vmax may provide more safety, but it may also distort higher voltage output signals, either because the
current is too high or the impedance is too high.
Drop-down Menu: The user can select maximum output voltages ranging from ±4.7V to ±9.5V
(0.6V) from the drop-down menu.
Update: Clicking the Update button updates any changes to the Output Vmax in the hardware.
Read: Clicking the Read button will return the measured analog voltage active in the system.
WARNING: Do not change CereStim R96 Output Vmax values while connected to the patient.
Doing so may result in an electric shock to the patient.
Log Window (10): The Log Window echoes commands sent from the Stim Manager Software to the
CereStim R96, provides updates on the connection status between the CereStim R96 and the PC, and
indicates any discrepancies in the Pulse Configurations or Stimulation Script. It also provides the user with
results from the Test Modules and Test Electrodes functions.
