|This command gets the device state (stored in its device_state data member) and returns it to the caller.|
|This command gets the device status (stored in its device_status data member) and returns it to the caller.|
|Imports the file defined by the FileName Attribute|
|Exports to the file described by the FileName attribute|
|BoardIdDevString||It must be an unique identifier for each card on the PC/Rack where it is installed. It could be the Board Number in the Rack, the Serial Number or the Product Id.|
|BoardTypeDevString||Product Descriptor that allow us to identify this card, its provider and its behavior|
|IsInputDevBoolean||Input/Output Direction of the Channels to be managed,defined in this context: 1. Each Tango Device will manage all the Channels of a same Type/Direction of a DAQ Card. 2. Wonât be two Analog Inputs accessing to the same Card; and two different devices (1 AI + 1 AO) will be needed to manage a Multi-Purpose Card with Channels of both types. -> The Read/Write permissions of the DoubleDATA, RawDATA, *ChannelValues and *LastValue Attributes will be determined by the value of this Property The value will be 1 for input, and 0 for output|
|OnBoardBufferDevLong||Onboard Buffer of the Physical Device.|
|MaxSampleRateDevLong||Maximum Sample Rate (per Channel) that is capable the DAQ Card. -> The SampleRate.MaxValue Attribute Property will be fixed each time this Property is modified.|
|MaxSourceRangeDevDouble||Maximum Source Range allowed (Bipolar), it is understood as +/-MaxSourceRange. -> The Attributes MaxSourceRef and MinSourceRef will adapt its MaxValue and MinValue Properties to the value stored in this Property.|
|DynamicRangeDevShort||Number of Bits of the DAQ Converter. -> It allows to convert from RawDATA (binary obtained from the Analog to Digital converter) to DoubleDATA (float point values normalized in the SourceRange).|
|UnitsDevString||Units concerning to the data measured/generated. -> This property will modify the units for all related Attributes.|
|NumOfChannelsDevShort||Total number of channels available in the DAQ card. This Property refers only to the Physical Channels of the same type of the Abstract Class (e.g. in an Analog Input Device it will refer only to the Analog Input Channels). -> It determines the maximum size of the Attribute BufferedChannels List and fixes the Attribute default value.|
|AutoStartDevBoolean||If set to `True` the command `start` will be run automatically after initialization. It will respect memorized attributes, so `start` will be performed AFTER all memorized attributes have been applied.|
