Section 4 
System Operation 

 

 

 

 

Introduction 

 

Once the operator is familiar with the D188 hardware and understands how the control software is 
operated, the next step is connection of the D188 to the source of stimulation, the stimulation electrodes 
and the digital trigger source.  A schematic of a typical setup is given below. 

 

 

The diagram above illustrates how a single PC and compatible DAQ hardware/software can be used to 
control the stimulation parameters of a Digitimer stimulator and direct electrical stimuli to one of up to 
eight pairs of electrodes, one pair at a time.
