Arguments (in C Syntax)

Full Description

12	Set Index	SetIndexPulsePolarity	(long CardHandle,		Selects the polarity of the index (marker) pulse coming from
	Pulse Polarity		short EncoderNumber,		user's encoder.
			short Polarity)
13	Get Index	GetIndexPulsePolarity	(long CardHandle,		Gets the current status of the Index Pulse Polarity (active on
	Pulse Polarity		short EncoderNumber,		high/low).
			short* Polarity)
14	Set "reset upon	SetIndexResetsPosition	(long CardHandle,		Defines whether a reset (=clear) of the Internal Position
	index"	Counter	short EncoderNumber,		Counter (IPC) should take place upon index (marker) pulse
			short EnabledDisabledMode)		coming from user's encoder.
					Note:
					The	eXternal Position Counter (XPC) is NOT affected
					immediately.
					Run RequestPositionCounter to apply the effect on the
					XPC, and ReadPositionCounter to read the XPC (refer to
					section 3.5.5, functions #26-27).
15	Get "reset	GetIndexResetsPosition	(long CardHandle,		Gets the current status of "reset upon index" (enabled or
	upon index"	Counter	short EncoderNumber,		disabled).
			short*EnabledDisabledMode)

Note: The description of the common arguments is in section 3.6
