Remarks
This function sets the scanner’s trigger output line state and polarity. Default is
DISABLED and POSITIVE. If
iState
is set to ENABLED, the trigger output is enabled,
which reflects in its activity during channel selection and during scanning operations.
With
iEdge
set to POSITIVE, the trigger output polarity will be positive, which means
that a positive edge on the trigger output line indicates a channel selection ready. See
definitions in ScanUser.H file.
