When NI-DAQmx attempts to contact a Network DAQ device, it uses addresses stored previously to connect to the device on the network. NI-DAQmx follows this sequence to contact Network DAQ devices: NI-DAQmx ...

The NI 9202, NI 9252, and NI 9253 use a combination of analog and digital filtering to provide an accurate representation of in-band signals while rejecting out-of-band signals. The filters discriminate ...

The NI 9775 module operates in two different modes, Continuous Mode and Record Mode. You can set the NI 9775 operation to be Record Mode by setting the DataXferReqCond attribute/property to When Acquisition ...

On X Series, M Series, and C Series devices, you can detect changes on digital lines or ports without using a buffer by specifying change detection timing with a buffer size of 0. To use change detection ...

OpenChansExist returns a Boolean of true if one or more channels were disconnected since the last time the attribute/property was queried, and OpenChans returns the virtual channel names of the channels ...

Two NI-DAQmx Read/Write attributes/properties allow you to check for disconnected sensors. The first is OpenCurrentLoopChansExist. This attribute/property returns a Boolean true if one or more channels ...

Breaking the hot junction of a thermocouple or disconnecting a thermocouple signal results in an open thermocouple channel. This causes the channel to return invalid data. Using open thermocouple detection, ...

Two NI-DAQmx Read/Write attributes/properties allow you to check for shorted channels. The first is OvercurrentChansExist. This attribute/property returns a Boolean true if one or more channels experience ...

An overtemperature condition occurs when the ambient temperature of the device exceeds a safe operating level. The device may disable any overtemperature channels until the ambient temperature returns ...

The source of your sample clock often can affect when your acquisition or generation pauses and resumes with the assertion and deassertion of a Pause Trigger. Counter Input for the NI 9361 When you acquire ...
