Enhancements and Bug Fixes in Version 15.0

Updated Experience in NI-MAX

The configuration experience in Measurement & Automation Explorer (MAX) has been updated to improve consistency with other NI products. Significant changes include:

  • GPIB properties have been moved to the Settings page for GPIB interfaces.
  • It is no longer necessary to run MAX as Administrator to change GPIB settings.
  • Reset and Self-Test features are now available for all GPIB interfaces from within MAX.
  • NI-488.2 DOS Support is no longer configurable through MAX; DOS Support is enabled by default on all compatible systems. Refer to the NI-488.2 documentation for instructions to manually disable NI-488.2 DOS Support.
  • Scan for Instruments no longer displays instruments at the bottom of the properties page, which has been removed. Discovered instruments only appear in the Devices & Interfaces tree beneath the GPIB interface.
  • GPIB-ENET/100 and GPIB-ENET/1000 interfaces now display additional information such as IP address and serial number.
  • Performance of MAX has been improved during startup and when expanding Devices & Interfaces tree.
  • GPIB-ENET/100 and GPIB-ENET/1000 interfaces which cannot be reached are marked as unavailable; some operations are disabled while they are offline. (386556)
  • Windows display language can now be changed without adverse affecting GPIB labels as they appear in MAX. (428596)
  • MAX now displays network info for GPIB-ENET/1000 interface that is configured with .local address. (409559)

Web Configuration

GPIB interfaces are now fully configurable through the NI Web Configuration interface. Self-Test has also been added.

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 14.0

New 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.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
