Cause : DAC parameters not set properly.DAC parameters should not be set to identical values, since this would produce illogical results.
- Index 0: Parameter settings for output identical
- Index 1: Parameter settings for input identical
- Index 2: Parameter settings for output do not correspond to DAC type
