Level Trigger Mode
In the Level trigger mode, stimulation also begins when the digital input for the channel transitions
from low (~0V) to high (~5V), but in level trigger mode, if the digital input is still high when the
stimulation protocol completes then the stimulation protocol will begin again immediately.
In the example above, the stimulation pattern consists of two repetitions of the 3 pulse burst
arbitrary waveform. The stimulation pattern is initiated by the rising edge in the digital input
marked 1. Because the digital input is high at the end of the first stimulation pattern (at the point
marked 2) the stimulation pattern starts playing a second time. Changes to the digital input during
the stimulation pattern are ignored (e.g. the pulse marked 3).

Edit/Load All
When the Edit/Load control is in Individual mode, the mode of each channel can be configured
using the individual Edit and Load controls in the row of controls dedicated to that channel.
Pressing the Edit All button causes all channels to switch to parameter editing mode. Note that
pressing Edit All will cause any stimulation pattern in progress on any channel to stop. Pressing the
Load All button will cause the stimulation parameters for all channels to be downloaded into the
stimulator.
Pressing Edit All or Load All will also cause individual channel edit and load contols to be grayed
out. Press the Individual button to configure the mode of each channel independently of the others.
Hint: You probably want to return the Edit/Load control to Individual after pressing Edit All or
Load All and there is no reason not to do so.
