The following list contains the NI hardware supported by NI-488.2 for Mac OS X, Version 14.1.0:
1Analyzer functionality is not supported.
2The GPIB-ENET/1000 has replaced the GPIB-ENET/100. Support for the GPIB-ENET/100 may not be maintained in future versions of NI-488.2 for Mac OS X. The GPIB-ENET/1000 should be used for new designs.
Refer to the NI-488.2™ for Mac OS X Getting Started Guide on the NI-488.2 for Mac OS X install media for installation instructions and system requirements.
To uninstall NI-488.2 for Mac OS X, refer to Uninstall.txt in the /Applications/National Instruments/NI-488.2 directory on the system.
NI-488.2 versions are now aligned with the versions of major NI application software products. This alignment gives you information about the year the driver was released and the most recent software version the driver was designed to work with. Driver versions now start with a two-digit year indicator: <ProductName><Year-BasedVersion>. For example, NI-488.2 for Windows 14.0 is the version of NI-488.2 released with LabVIEW 2014. The last version of NI-488.2 released under the old numbering scheme is NI-488.2 for Linux 3.2. The first version released under the new numbering scheme is NI-488.2 for Windows 14.0.
Modified the integer types used in ni4882.h and NI4882.Framework. All uses of unsigned long have been replaced with unsigned int to improve compatibility with 64-bit compilers. This API has never been documented with prior versions of NI-488.2 for Mac OS X, but ni4882.h and a 32-bit version of NI4882.framework were installed on the system. Any user utilizing these files should update their applications according to the updated function prototypes in ni4882.h. This change does not impact ni488.h or NI488.framework.
Note: This change remains binary compatible with any user who may have previously compiled against NI4882.Framework.
NI-488.2 for Mac OS X, Version 14.1, adds a 64-bit application interface that allows users to create 64-bit applications using the NI4882 framework. Using the 32-bit version of NI4882 framework, users can use the same NI4882 API to build corresponding 32-bit applications with no source code changes. For more information about the new NI4882 API, refer to the NI-488.2 Help. You can access NI-488.2 Help from GPIB Explorer by selecting Help»Help Topics»NI-488.2 from the menu bar.
NI-488.2 for Mac OS X, Version 14.1, installs NI-VISA and NI-MAX by default. Installation can be customized by selecting Customize button during the Installation Type step.
NI-488.2 now reports GPIB controller interfaces through the NI System Configuration API.
NI-488.2 for Mac OS X does not support power management. You must disable the Energy Saver Sleep Modes or make sure all GPIB handles are offline before the system enters Sleep Mode.
The following items are the IDs and titles of a subset of issues fixed in NI-488.2 for Mac OS X, Version 14.1.0. This is not an exhaustive list of issues fixed in the current version of NI-488.2. If you have a CAR ID, you can search this list to validate that the issue has been fixed.
| Request ID | Description |
|---|---|
| 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. |
| 240000 | On GPIB-USB-B and GPIB-USB-HS controllers, ibwait and ibnotify could fail to detect the CIC, LACS, and TACS bits. |
| 332479 | On GPIB-USB-B and GPIB-USB-HS controllers, the first I/O operation after device insertion could be terminated prematurely. |
| 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. The data is then lost and cannot be recovered. |
| 394848 | If a GPIB controller is connected to a USB port on a Thunderbolt display, disconnecting and then reconnecting the display can cause the host machine to become unresponsive. |
| 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. |
| 425931 | Calling ibstop with an asynchronous operation in progress would sometimes not report an EABO error as expected. |
Version 3.0.1
NI-488.2 for Mac OS X now functions when using a 64-bit Mac OS X kernel.
The GPIB-ENET/100 has been replaced by the GPIB-ENET/1000. The GPIB-ENET/1000 is configured using a web interface. This interface may be launched from within GPIB Explorer, or by discovering the GPIB-ENET/1000 web server using the BonJour pane in the Safari web browser.
The standalone Ethernet Config and Firmware Update utilities are no longer installed. Ethernet devices are now discovered and configured from within GPIB Explorer. NI-488.2 for Mac OS X no longer includes a utility to update the firmware on a GPIB-ENET/100 device. Should you require this capability, contact National Instruments for support.
NI Spy is replaced by NI I/O Trace.
