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：

NI-VISA 21.0 Driver Full MacOs64Eng 美国国家仪器虚拟仪器软件架构NI-VISA21.0 MAC完整版驱动下载
NI-VISA为使用GPIB、串行、PXI和其他类型仪器的用户提供支持。
NI-VISA是一个NI仪器驱动程序，是虚拟仪器软件架构(VISA) I/O标准的具体实现。虚拟仪器软件架构(VISA)这一标准用于配置和编程基于GPIB、VXI、PXI、串口(RS232/485)、以太网/LXI和/或USB接口的仪器系统以及故障分析。NI-VISA包括实用程序、底层控制功能和范例，可帮助您快速创建应用程序。
注意，NI-VISA从VISA14.0版开始，使用年代名称来命名，即14代表的是2014年，不再延续之前的5.X之类的名称。而在VISA5.4.1及之前的版本，则是使用数字版本来命名的，5并不是代表着2005年之类的。

Installation InstructionsLabVIEW Installation
You can install all of your LabVIEW products—including NI-VISA—using the LabVIEW 2021 Platform media. Refer to the LabVIEW Installation Guide on the LabVIEW Platform media for installation instructions and system requirements.
To request additional LabVIEW Platform media, visit ni.com/r/media.
Note If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.
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.
