Parameters

resourceName

resourceName specifies the resource name of the device to initialize.

Syntax
Variable
1
NI-DAQmx device
myDAQmxDevice
(myDAQmxDevice = device name)
2
NI-DAQmx device
DAQ::myDAQmxDevice
(myDAQmxDevice = device name)
3
NI-DAQmx device
DAQ::2
(2 = device name)
4
IVI logical name or IVI virtual name
myLogicalName
(myLogicalName = name)
For NI-DAQmx devices, the syntax is just the device name specified in MAX, as shown in Example 1. Typical default names for NI-DAQmx devices in MAX are Dev1 or PXI1Slot1. You can rename an NI-DAQmx device by right-clicking on the name in MAX and entering a new name.
An alternate syntax for NI-DAQmx devices consists of DAQ::NI-DAQmx device name, as shown in Example 2. This naming convention allows for the use of an NI-DAQmx device in an application that was originally designed for a Traditional NI-DAQ device. For example, if the application expects DAQ::1, you can rename the NI-DAQmx device to 1 in MAX and pass in DAQ::1 for the resource name, as shown in Example 3.
If you use the DAQ::n syntax and an NI-DAQmx device name already exists with that same name, the NI-DAQmx device is matched first.
You can also pass in the name of an IVI logical name or an IVI virtual name configured with the IVI Configuration utility, as shown in Example 4. A logical name identifies a particular virtual instrument. A virtual name identifies a specific device and specifies the initial settings for the session.
Note NI-DAQmx device names are not case-sensitive. However, all IVI names, such as logical names, are case-sensitive. If you use logical names, driver session names, or virtual names in your program, you must make sure that the name you use matches the name in the IVI Configuration Store file exactly, without any variations in the case of the characters.

ViStatus
Reports the status of this operation. To obtain a text description of the status code, call niScope_GetErrorMessage. To obtain additional information concerning the error condition, use niScope_GetError and niScope_ClearError. The general meaning of the status code is as follows:
Generates the CableSense signal on all channels of an oscilloscope for which the signal is enabled, as configured by the NISCOPE_ATTR_CABLE_SENSE_MODE attribute.
Note The input impedance of the channel(s) to convey the CableSense signal must be set to 50 Ω.
You can call this function only during an acquisition. If you call this function while your oscilloscope is not acquiring, NISCOPE generates an error.
