Known Issues
The following are known issues for NI-SWITCH 4.1:
Certain system timer settings on Windows 7 machines could result in degraded connect/disconnect performance on NI switch products. For more information about the effect of system timer settings on switch performance, visit ni.com/info and enter the info code, win7switch.
If you click a topic link in the NI-SWITCH Function Reference Help section of the NI Switches Help, you cannot use the Back button in the HTML Help window toolbar to return to the original topic.
When linking to a topic in the NI Switches Help from the context help or opening the help file from a VI within LabVIEW, the NI Switches Help launches and the relevant topic displays, but the location of the topic might not be highlighted in the table of contents.
Various support files, such as .h and .lib files, are installed in \Program Files\IVI 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:
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.
NI-DMM 2.2
NI-DMM 2.2 updated the niSwitch DMM Switch Handshaking example for LabVIEW. 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.
When you run setup.exe to install the software from the media, you are prompted to choose whether you want to always trust software from National Instruments. If you do not select this option, your installation may be interrupted by one or more Microsoft Windows security dialog boxes. However, if you run the installer in silent mode from the command line, you will not receive this prompt, and the installer will automatically install NI's Software Publisher Certificate to the your Windows Trusted Publisher Store. If you do not want to make this change to your Windows Trusted Publisher Store, do not choose this installation method.
NI recommends that you disable Windows power management modes, such as sleep, standby, and hibernate, when using this product. These modes terminate any NI-SWITCH operation in progress. Notice that in Windows Vista or on a laptop computer, the default power management settings are likely to enable sleep mode.
Reverting to NI-SWITCH 1.6 after installing NI-SWITCH 4.1
If reverting back to NI-SWITCH 1.6 from NI-SWITCH 4.1, you must uninstall NI-SWITCH 4.1 and reinstall NI-SWITCH 1.6.
