Matchcode

Sequence on Mismatch

Note: Matchcode Type
Enable this parameter if every trigger event should have a decode and more than one
consecutive mismatch may occur. When set to Enabled, the master symbol sequences on
every decode, match, or mismatch.
Disable this parameter if every trigger event should have a decode but no more than one
consecutive mismatch may occur. When set to Disabled, the master symbol will not
sequence whenever consecutive mismatches occur.
The scanner will sequence the master to one more or one less than the decoded symbol.
Consider the following decodes as an example of Sequence on Mismatch Enabled:
