DAQ hardware. These ActiveX controls provide a high-level programming
interface for building virtual instruments (VIs). For Visual C++ developers,
Measurement Studio offers a set of Visual C++ classes and tools to
integrate those classes into Visual C++ applications. The ActiveX controls
and classes are available with Measurement Studio and the NI-DAQ
software.
VI Logger is an easy-to-use yet flexible tool specifically designed for data
logging applications. Using dialog windows, you can configure data
logging tasks to easily acquire, log, view, and share your data. VI Logger
does not require any programming; it is a stand-alone, configuration-based
software program.
Using LabVIEW, LabWindows/CVI, Measurement Studio, or VI Logger
greatly reduces the development time for your data acquisition and control
application.
Optional Equipment
NI offers a variety of products to use with the NI 6115/6120, including
cables, connector blocks, and other accessories, as follows:
• Shielded cables and cable assemblies
• Connector blocks, shielded 50- and 68-pin screw terminals
• RTSI bus cables (PCI only)
• Low channel-count signal conditioning modules, devices, and

Custom Cabling
NI offers cables and accessories to help you prototype your application or
to use if you frequently change device interconnections.
If you want to develop your own cable, however, adhere to the following
guidelines for best results:
• For AI signals, use shielded twisted-pair wires for each AI pair for
differential inputs. Tie the shield for each signal pair to the ground
reference at the source.
