setVoltage()

void DSC_AnalogOut::setVoltage	(	int	which,
		float	val )

Set a voltage on an output.

Parameters

which	Which VOUT pin, numbered from 0.
val	Desired voltage value. If val is outside the known limit of the D2A, the request will be changed to the corresponding limit value. Throws nidas::util::InvalidParameterException if "which" is out of range.

setVoltages()

void DSC_AnalogOut::setVoltages	(	const std::vector< int > &	which,
		const std::vector< float > &	val )

Set one or more outputs.

Parameters

which	Vector of VOUT pin numbers, numbered from 0.
val	Desired voltage values. If a val is outside the known limit of the D2A, the request will be changed to the corresponding limit value. Throws nidas::util::InvalidParameterException if "which" is out of range.
