int SCANTriggerOutStete(int iScan, int iState, int iEdge)

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.
