视觉论坛的各种资源，除了视觉相关的模块有使用外，大部分的都不会使用，所以仅提供资源不能提供技术支持。资源的下载地址一般会同时提供NI官方地址和百度网盘的下载地址。某些工具包NI的地址失效或没有NI的下载地址，那视觉论坛也没有办法，只能尝试使用百度网盘地址下载；如果百度网盘的下载地址失效过期，可联系论坛客服更新。现在NI的下载服务器对我国IP地址不是很友好，有些时候速度很慢或大的资源下载很容易出错，这样会造成安装过程各种类型报错而无法安装。建议在下载完成后，对下载资源做校验和验证（NI一般会提供MD5或SHA256等），与官方或视觉论坛提供的校验和对比，一致就可以安装，如果不一致，则需要重新下载。视觉论坛早期下载的资源，那时候NI没有这么多限制，基本上都是正常下载的资源；后期下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘，所以百度网盘的资源基本上是正确的。校验和工具下载地址：

Important Information
Using NI-VISA 5.4Supported Platforms
NI-VISA 5.4 for Macintosh supports the following platforms:
1 64-bit VISA applications are supported for a limited set of instrumentation buses. The supported buses are ENET-Serial, USB, and TCPIP. Logging VISA operations in NI I/O Trace from 64-bit VISA applications is not supported.
Supported Development Environments
NI-VISA for Macintosh supports LabVIEW 2009 or later.
Installed Files and Paths
There are three main locations where NI-VISA installs files.
The local /Library/Frameworks folder contains the VISA.framework folder. This folder contains all needed headers and supporting Passport libraries that NI-VISA uses.
In the local /Applications/National Instruments folder, there is an NI-VISA folder. This folder includes the NI-VISA Help, as well as several groups of C examples using NI-VISA. This NI-VISA folder also includes a graphical utility called NI-VISA Configuration to configure VISA options and the VISA Interactive Control (VISAIC).
Finally, the /Library/Preferences folder contains an NIvisa folder with .ini files. These files are used for NI-VISA settings and status codes.

Added support for 64-bit kernel for Mac OS X.
Added Mac OS X 10.7 support.
NI-VISA 5.1
Added support for HiSLIP.
Added the VISA Interactive Control (VISAIC) stand-alone application. Refer to the NI-VISA Help for more information on the updates to VISAIC.
NI-VISA 5.0
Added Mac OS X 10.6 support.
Added support for 64-bit formatted I/O.
Dropped GPIB-VXI support.
NI-VISA 4.5
Added automatic detection of LXI (TCP/IP) devices that support the mDNS and DNS-SD technologies.
NI-VISA 4.0.1
Added support for the PXI/PCI Passport on the x86 architecture.
Added native support for the NI-VISA Configuration Utility on the x86 architecture.
NI-VISA 4.0
Added support for Mac OS X on the x86 architecture, aka Mactel.
Added support for 64-bit data transfers in register-based operations, to support the VISA 4.0 specification.
Added support for DTR/DSR flow control. The Agilent 34401A requires DTR/DSR flow control when used via Serial. Note that not all Serial port drivers on the Mac support DTR/DSR. We have tested the Agilent 34401A with NI-VISA 4.0 using the Keyspan USA-19HS and verified that it works properly.
