Name Description
AI.MeasTypes Indicates the measurement types supported by the channel.
AI.TermCfgs Indicates the list of terminal configurations supported by the channel.
AI.InputSrcs Indicates the list of input sources supported by the channel. Channels may support using the signal from the I/O connector or one of several calibration signals.
AI.SensorPower.Types Indicates the types of power supplied to the sensor supported by this channel.
AI.SensorPower.VoltageRangeVals Indicates pairs of sensor power voltage ranges supported by this channel. Each pair consists of the low value followed by the high value.
AI.PowerControl.Voltage Specifies the voltage level for the sensor's power supply.
AI.PowerControl.Enable Specifies whether to turn on the sensor's power supply.
AI.PowerControl.Type Specifies the type of power supplied to the sensor.
AI.SensorPower.OpenChan Indicates whether there is an open channel or undercurrent condition on the channel.
AI.SensorPower.Overcurrent Indicates whether there is an overcurrent condition on the channel.
AO.OutputTypes Indicates the output types supported by the channel.
AO.PowerUpOutputTypes Indicates the power up output types supported by the channel.
AO.TermCfgs Indicates the list of terminal configurations supported by the channel.
AO.ManualControl.Enable Specifies if you can control the physical channel externally via a manual control located on the device. You cannot simultaneously control a channel manually and with NI-DAQmx.
AO.ManualControl.ShortDetected Indicates whether the physical channel is currently disabled due to a short detected on the channel.
AO.ManualControl.Amplitude Indicates the current value of the front panel amplitude control for the physical channel in volts.
AO.ManualControl.Freq Indicates the current value of the front panel frequency control for the physical channel in hertz.
AO.PowerAmp.ChannelEnable Specifies whether to enable or disable a channel for amplification. This property can also be used to check if a channel is enabled.
AO.PowerAmp.ScalingCoeff Indicates the coefficients of a polynomial equation used to scale from pre-amplified values.
AO.PowerAmp.Overcurrent Indicates if the channel detected an overcurrent condition.
AO.PowerAmp.Gain Indicates the calibrated gain of the channel.
AO.PowerAmp.Offset Indicates the calibrated offset of the channel in volts.
DI.PortWidth Indicates in bits the width of digital input port.
DI.SampClkSupported Indicates if the sample clock timing type is supported for the digital input physical channel.
DI.SampModes Indicates the sample modes supported by devices that support sample clocked digital input.
DI.ChangeDetectSupported Indicates if the change detection timing type is supported for the digital input physical channel.
DO.PortWidth Indicates in bits the width of digital output port.
DO.SampClkSupported Indicates if the sample clock timing type is supported for the digital output physical channel.
DO.SampModes Indicates the sample modes supported by devices that support sample clocked digital output.
CI.MeasTypes Indicates the measurement types supported by the channel.
CO.OutputTypes Indicates the output types supported by the channel.
TEDS.MfgID Indicates the manufacturer ID of the sensor.
TEDS.ModelNum Indicates the model number of the sensor.
TEDS.SerialNum Indicates the serial number of the sensor.
TEDS.VersionNum Indicates the version number of the sensor.
TEDS.VersionLetter Indicates the version letter of the sensor.
TEDS.BitStream Indicates the TEDS binary bitstream without checksums.
TEDS.TemplateIDs Indicates the IDs of the templates in the bitstream in TEDS.BitStream .
