Return
Instrument I/O Assistant code generation fails when the FIPS algorithm policy is enabled.
The Instrument I/O Assistant fails to generate code in Measurement Studio for Visual Studio 2005 and Visual Studio 2008 when the FIPS (Federal Information Processing Standards) algorithm policy is enabled on a machine.

Workaround: 1. Disable the FIPS algorithm policy on the machine.
2. Open or restart Visual Studio 2005 or Visual Studio 2008 and re-generate code in the Instrument I/O Assistant.
3. Re-enable the FIPS algorithm policy on the machine.

See this Microsoft KB for more information.

Return
Viewing NI-VISA Options tab on Real-Time controller may hang MAX
On PXI and PC Real-Time controllers with VISA Server installed, MAX occasionally may hang when trying to view the VISA Options tab.

Workaround: N/A

109538

Return
Slot path shows up incorrectly for multifunction and bridged NI-VISA-based PXI devices
PXI devices that are either behind a PCI bridge or have multiple functions (for example, both Ethernet and SCSI device) show an incorrect slot path in MAX when using a driver generated by the VISA Driver Development Wizard.

Workaround: N/A

126535

Return
VISA Read STB on Mac OS X waits for NI-VISA-defined timeout even if USB device responds sooner
VISA Read STB always waits for the timeout defined in NI-VISA before returning, even if a USB device returns a response quicker than the timeout value.

Workaround: N/A

145966

Return
Third-Party USB device communication may timeout after host PC is put into standby
A Windows-based machine communicating with a third-party USB device using a driver not developed by the VISA Driver Development Wizard may timeout if the PC is put into standby mode in the middle of a NI-VISA USB transfer. After the PC is woken up, it thinks the USB device should resend the entire data packet and eventually times out because the packet is not resent.

Workaround: N/A

166323

Return
Using interrupts with NI-VISA-based PXI cards on NI RT Hypervisor system may cause hang on reboot
If you are using interrupts with a PXI card that uses an NI-VISA-based driver on an NI RT Hypervisor system, independent reboot of the RT system may hang if the driver does not have the interrupt disarm sequence defined.

Workaround: N/A

Reported Version: 4.5.1  Resolved Version: N/A  Added: 08/25/2010
182027

Return
Setting serial baud rate with NI-VISA may return errors from third-party serial drivers
NI-VISA may return an error while setting the serial baud rate when using third-party serial drivers, even though setting this same baud rate may work in other third-party applications. This is due to how NI-VISA verifies baud rate settings.

Workaround: N/A

183242

Return
Calling viUsbControlIn on composite USB devices may cause system to blue screen
When using viUsbControlIn or VISA USB Control In.vi, if a composite USB RAW device is passed in as the VISA resource, the system may crash with a blue screen.

Workaround: N/A

3WP9E800


Return
NI-VISA leaks Mach ports on Mac OS X when communicating with USB Raw devices
When performing a VISA Open and VISA Close on a USB Raw device multiple times inside a loop, the number of Mach ports in Mac OS X increases. This may cause a crash if the code performing these calls is run over an extended period of time.

Workaround: Restart the development/run-time environment

Reported Version: 3.4  Resolved Version: 4.5  Added: 08/25/2010
242354

Return
VISA always adds a parallel port resource
VISA will always add a static resource bound to LPT1 in visaconf.ini. If a system does not have a parallel port, this resource will show up with a yellow exclamation mark in MAX.

Workaround: Delete the parallel port in MAX

Return
Two applications simultaneously calling viLock and viUnlock on the same VISA INSTR resource will eventually result in an error
Two applications that are both trying to lock and unlock a VISA INSTR resource using viLock and viUnlock will result in one of the applications eventually returning error -1073807204: VISA: (Hex 0xBFFF009C) The current session did not have a lock on the resource.

Workaround: N/A

283686

Return
Rebooting a system or refreshing Devices & Interfaces in MAX will remove a key in visaconf.ini
If the following key is added to disable the error replacement character when performing 9-bit VISA serial reads, refreshing Devices & Interfaces in MAX or rebooting the system will remove that key from visaconf.ini:
[ASRL-RSRC-ALIAS]
DisableErrorReplacement=1

Workaround: N/A

308006

Return
Providing VISA remote access to a cRIO device may cause duplicate Serial & Parallel entries in MAX
Adding a new permission to the Remote Access List under the VISA Server for a cRIO device may cause duplicate Serial & Parallel entries to appear underneath the device in MAX.

Workaround: N/A

366314

Return
TCP VISA Read/Write calls have 2000 ms timeout.
If you pass an invalid TCP resource to VISA Read or VISA Write, the call will take 2000 ms to timeout. This occurs regardless of the timeout value originally specified with the VISA Set Timeout call.

Return
Only serial aliases are returned with I/O Name Filtering in LabVIEW 32-bit.
When using I/O Name Filtering with Include these Aliases set to All defined aliases for resources of this class, LabVIEW 32-bit only returns serial aliases. For LabVIEW 64-bit, all defined aliases are returned.

Workaround: Set the aliases with MAX.
