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：

New Features in NI-SWITCH 3.3.1

• New NI PXI-2584 example for interleaved scanning

• NI PXI-2584 independent topology schematic in the Switch Soft Front Panel

• New Behavior—For NI-DAQmx devices, initializing a session now closes any other existing sessions open to the same device in the same process. Calling niSwitch_init, niSwitch_InitWithTopology, or niSwitch_InitWithOptions therefore always results in the creation of a new session rather than returning an existing session. This new behavior does not apply to sessions to Traditional NI-DAQ (Legacy) devices and NI-VISA based devices.

• Fixed intermittent timeout errors on switch hardware after cold boot when using NI-SWITCH 3.1 or NI-SWITCH 3.3.
  

Supported Hardware

• NI SCXI-1127/1128/1129/1130/1160/1161/1163R/1166/1167/1169/1175/1190/1191/1192/1193/1194/1195

Known Issues

• If reverting back to NI-SWITCH 1.6 from NI-SWITCH 3.3.1, you must uninstall NI-SWITCH 3.3.1 and reinstall NI-SWITCH 1.6.

• Various support files, such as .h and .lib files, are installed in Program FilesIVI and VXIpnp directories to support ADEs that only recognize the VXIpnp directory.

• SCXI-1127 (Rev D and earlier) continuously drives the TTL1 trigger line on the SCXI backplane. This does not allow bus sharing of TTL1 with other SCXI modules. NI-SWITCH returns an error if an SCXI-1127 is in the chassis and if TTL1 is being used for scanning. If using the NI-DAQmx driver for your SCXI system, you get a resource reservation error if you try to perform a switching or signal conditioning operation that requires use of TTL1.

• There are known DLL collision issues with the Microsoft Visual Basic debugger and a National Instruments device driver using Traditional NI-DAQ (Legacy). A support DLL used by NI-SWITCH fails to load if Visual Basic has already loaded another DLL into the same address space. To change the default address that is used to load the driver DLL, create the following registry key:
  
  \HKEY_LOCAL_MACHINESOFTWARENational InstrumentsNI-PALCurrentVersionpalConfigMemory
  sharedFixedAddress
  
  where the value is a DWORD (0x44000000 generally works).
  
  For the change to take effect, you must close and restart all applications after adding the registry key.

• The niSwitch DMM Switch Handshaking example for LabVIEW was updated with NI-DMM 2.2. If you have an earlier version of NI-DMM installed, the VI is inoperable.
  
  To use the example with NI-DMM 2.1.2 or earlier, delete the AUX Trig 1 case from the case structure connected to Sample Trigger Source in the niDMM Configure Multi Point VI.
  
  NI-DMM 2.2 introduces a new enumerated value, AUX Trig 1.
  

Changes by Release3.3.1 from 3.3

• Fixed intermittent timeout errors on switch hardware after cold boot when using NI-SWITCH 3.1 or NI-SWITCH 3.3.
  

3.3 from 3.1

• New NI PXI-2584 example for interleaved scanning

• NI PXI-2584 independent topology schematic in the Switch Soft Front Panel

• New Behavior—For NI-DAQmx devices, initializing a session now closes any other existing sessions open to the same device in the same process. Calling niSwitch_init, niSwitch_InitWithTopology, or niSwitch_InitWithOptions therefore always results in the creation of a new session rather than returning an existing session. This new behavior does not apply to sessions to Traditional NI-DAQ (Legacy) devices and NI-VISA based devices.
  

3.1 from 3.0

• Support for the NI PXI-2584 switch module
