Method Summary

Modifier and Type	Method and Description
protected int[]	checkChannel(String chName, int hwChan, String type, String subtype) Checks a channel's parameters for validity.
protected void	close() Closes the connection.
void	closeShutter() Command to close shutter
void	exposure(Duration duration) Command to open shutter for a specified time interval
protected void	initDevice() Performs basic initialization.
protected void	initialize() Performs full initialization.
boolean	isShutterClosed() Check whether shutter is closed or open
void	openShutter() Command to open shutter
String	readAll() Read all settings and data from shutter controller Loops over all read commands and returns them in a table format.
protected double	readChannel(int hwChan, int type) Reads a channel.
void	setOutputMode(Boolean mode) Select mode for output signal
