When the List Mode is activated, the three stimulator units are coupled to a single starting
trigger. The starting trigger is set in the tab of the first stimulator unit, Stimulus 1. In Stimulus 2
and 3, the respective functions are disabled. To uncouple the stimulator units again, close the List
Mode dialog. The step from one stimulation pattern to the next in the list happens when the start
condition defined for Stimulus 1 occurs (for example, manual start, incoming trigger, real-time
feedback trigger) and all three stimulator units are idle. Please see the red bars on the picture.
However, the next pattern can only be started by the respective starting condition when the
previous stimulation paradigm, including all breaks, is completely finished.
That means, if one stimulation pattern of any of the three stimulator units is still running
when the condition occurs, nothing will happen. This also holds true when a stimulator unit
is not actually used in the currently active stimulation pattern.
Hence, the longest programmed stimulation pattern determines the minimum possible time
between two starting triggers, even if the respective stimulator unit is not actually used. It is
therefore advisable to set a stimulation pattern with a length of 0 on all unused stimulator units,
and keep all patterns as short as possible.
A stimulation pattern can contain single or multiple stimulation electrodes and may get an
user defined name. To create a list of different stimulation patterns, please do the following.
Click the button “List Mode”. There are two windows in the “List of Stimulus Pattern”. The small
window on the right side is for typing in a name for a pattern. In the window on the left side the
list of stimulation pattern will be displayed and arranged.
When opening the “List Mode” for the first time, the term “New” appears and the current
stimulation pattern is the first stimulation pattern in the list. To change the name, please
overwrite the name with the specific name of this pattern in the small window.
To insert a stimulation pattern, select with the mouse the position in the list where you want
to place the pattern. The line will be highlighted in blue. Type the specific name of this pattern
in the small window. Click the button "New" and the new list entry appears.
To append a pattern, select the line under the last list entry. The line will be highlighted in blue.
Type the specific name of this pattern in the small window. Click the button "New" and the new
list entry appears.
To rename a pattern of the list, select the pattern which will be highlighted in blue.
Then you can change the name of the pattern in the list. Please click the “Rename” button.
