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：

Removed Troubleshooting Utility
The NI-488.2 Troubleshooting Utility has been removed. GPIB interfaces may be tested using the Self-Test feature in Measurement & Automation Explorer, or programmatically through the System Configuration API.
Improved Behavior When USB Transaction Errors Occur
506688: The NI-488.2 driver is unable to recover from certain types of USB errors. These errors may occur on some systems when other USB devices are added or removed from the system while a GPIB operation is in progress. In prior versions of NI-488.2, this could lead to a hang in the process using a USB-to-GPIB interface. It could also result in a hang or blue screen error on system shutdown. This scenario now results in an EDVR error when an unrecoverable USB error occurs. To restore operation, the USB connection to the GPIB interface should be removed and reinserted, and the GPIB handle should be closed and re-opened.
The Following Issues Were Resolved in NI-488.2 15.0
518983: As a result of an issue introduced in NI-488.2 14.0, GPIB-USB-B or GPIB-USB-HS I/O bus communication can hang until the handle to the GPIB interface is closed when all of the following conditions are true:
The affected interface is not CIC (Controller in Charge)
A read or write is in progress
An ibwait including the DCAS bit is in progress
A device clear is received during the I/O transfer
507376: Installer hang might occur during installation of NI software on systems with NI-488.2 14.0 already installed.
478063: GPIB-USB-HS+ might become unresponsive upon rebooting in a virtual machine.
121091: Calling ibonl when a board level ibwait is in progress could result in application crash.
121181: A deadlock might occur when attempting to use a board handle with pending ibonl call on another thread.
476357: GPIB Ethernet Wizard can incorrectly add GPIB-ENET/1000 with hostname even if it is not reachable.
476487: GPIB Ethernet Wizard icon does not appear on Windows task bar.
Enhancements and Bug Fixes in Version 14.0New Hardware Support
This release adds support for the GPIB-USB-HS+ GPIB controller and Analyzer. Along with this, the NI GPIB Analyzer utility has undergone changes to allow it to work with the new analyzer hardware. The NI GPIB Analyzer utility allows simultaneous use of multiple GPIB-USB-HS+ analyzers, along with up to one non-USB GPIB analyzer.
Windows Server Support
This release adds support for Windows Server 2012 R2. Refer to the Supported Hardware section for the list of supported hardware.
API Integer Type Changes
The integer types used in the NI4882 API (ni4882.h) have been updated. All uses of unsigned long have been replaced with unsigned int. These types are functionally identical with all supported compilers, and this change improves the portability of 64-bit GPIB applications to other platforms. Users of ibnotify will need to update the function prototypes for callback functions. In most other cases applications will compile cleanly. This change is fully binary-compatible with applications built against previous versions of NI-488.2 and does not impact users of the GPIB-32 API (ni488.h).
Runtime Installer
NI-488.2 for Windows is now available in a smaller Runtime form. The NI-488.2 Runtime is a minimal installation which does not include many of the utilities and supporting software included with the full NI-488.2 distribution. When building installers from LabVIEW or other NI development environments, you will now have the option of including this smaller subset of NI-488.2 in your distribution.
The Following Issues Were Resolved in NI-488.2 14.0
319093: Attempting to bring a non-existent device online after setting the IbcSendLLO board configuration option causes an ENOL error instead of EBUS. This problem impacted all USB based GPIB interfaces. This has been fixed.
122997: The EOIP status bit could remain set incorrectly if an ibwrta or ibrda call returned an EDVR error.
171688: An ibnotify callback could fail to be triggered by END if the notify condition included END but not CMPL.
205182: Asynchronous transfers could sometimes report EABO even though the transfer completed successfully.
372832: A callback from ibnotify might not be invoked after an asynchronous transfer was completed if the notify mask only contained END.
374822: Calling ibonl while ibnotify is pending could cause the process to crash under some circumstances.
380705: Aborting an ibrda very quickly after starting it could allow a PCI-based GPIB interface to receive data when addressed as a listener, without a read in progress. This data was lost, and could not be recovered.
404267: In some situations, the GPIB-ENET/1000 could hang while performing asynchronous transfers. This included fixes in both the NI-488.2 driver and the GPIB-ENET/1000 firmware. Users of the GPIB-ENET/1000 should update the GPIB-ENET/1000 firmware to version 1.1.0 to receive the full benefit of this fix.
405414: In some cases the DCAS bit was not correctly cleared after being reported, causing it to be reported with subsequent calls.
418661: In some situations, when an ibnotify callback function was triggered due to the completion of an asynchronous transfer, the ibcnt and ibcntl variables would be incorrect.
425931: Calling ibstop with an asynchronous operation in progress would sometimes not report an EABO error as expected.
464114: When using a GPIB-USB-B controller, the call immediately following an ibstop call could be incorrectly aborted.
463966: Severe performance degradation when performing large writes to GPIB-USB-HS hardware through USB 3.0 ports on Windows 7.
332479: On GPIB-USB-B and GPIB-USB-HS controllers, the first I/O operation after device insertion could be terminated prematurely.
240000: On GPIB-USB-B and GPIB-USB-HS controllers, ibwait and ibnotify could fail to detect the CIC, LACS, and TACS bits.
191044: The GPIB Analyzer did not automatically append the correct file extension when saving a capture.
87073: The GPIB Analyzer did not prompt to save if the application is closed while capturing data.

API整数类型改动
NI4882 API (ni4882.h)的整数类型已更新。所有使用unsigned long的位置，均被替换为unsigned int。该数据类型与支持的编译器功能上完全一致，提高了64位GPIB应用程序在其他平台上的适用性。ibnotify的用户将需要更新回调函数的函数原型。在大多数其他情况下，应用程序重新编译即可。使用较早版本NI-488.2生成的应用程序不受影响。该改动也不会影响GPIB-32 API (ni488.h)的用户。
运行引擎安装程序
用于Windows的NI-488.2现可通过较小的运行引擎模式安装。NI-488.2运行引擎的安装文件较少，不包括NI-488.2完整发布中包含的工具和支持软件。当从LabVIEW或其他NI开发环境构建安装程序时，可选择在软件发布中包含较少数量的NI-488.2文件。
NI-488.2 14.0解决了下列问题
319093：设置IbcSendLLO板卡配置选项后尝试连接不存在的设备时，提示ENOL（而非EBUS）错误。此问题影响所有基于USB的GPIB接口。该问题已解决。
122997：如ibwrta或ibrda调用返回EDVR错误，EOIP状态位可能保持错误设置状态。
171688：如通知条件包含END但不包含CMPL，则ibnotify回调可能无法触发。
205182：即使传输成功完成，异步传输也可能会报告EABO。
372832：如通知掩码仅包含END，则异步传输完成后ibnotify回调可能无法调用。
374822：某些情况下，ibnotify等待时调用ibonl可能引起进程崩溃。
380705：启动ibrda后迅速将其中止可允许基于PCI的GPIB接口编址为侦听器时接收数据，无需进程中的读取操作。数据丢失，无法恢复。
404267：在某些情况下，GPIB-ENET/1000可能在执行异步传输时崩溃。NI-488.2的驱动程序和GPIB-ENET/1000固件都进行了相应改进。GPIB-ENET/1000用户应将固件更新至1.1.0版，以修复该问题。
405414：在某些情况下，报告后，DCAS位未正确清除，导致其后的调用继续报告该位。
418661：某些情况下，ibnotify回调函数因异步传输完成触发时，ibcnt和ibcntl变量可能不正确。
425931：异步操作过程中调用ibstop有时可能不会报告预期的EABO错误。
