Self-Test and Device Reset features are now available for all GPIB interfaces from within MAX.

Self-Test and Device Reset features are now available for all GPIB interfaces from within Measurement & Automation Explorer (MAX). GPIB interfaces may be tested using the Self-Test feature, or tested programmatically through the System Configuration API. The Device Reset feature resets the selected GPIB hardware.

Note:  Although the NI-488.2 Troubleshooting Wizard remains available in this release, the functionality is deprecated in favor of the Self-Test feature.

Performance of MAX has been improved.The GPIB-ENET/1000 configuration page can be launched using the Device Configuration command in MAX.The following issues were resolved in NI-488.2 15.5.

12109: 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.

433395: Extra delay on ibwait and ibstop was removed for GPIB Ethernet-based hardware.

478063: GPIB-USB-HS+ might become unresponsive upon rebooting in a virtual machine.

518983: As a result of an issue introduced in NI-488.2 14.1, 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

545813: On OS X 10.11, signal termination (for example, Control + C) of a pending ibwrt with a large buffer causes subsequent ibfind to fail for GPIB-USB-HS.

546910: GPIB Explorer and Troubleshooting Wizard fail to launch after upgrading from 3.0.1 or below to 14.1 on Mac OS X 10.11.

Enhancements and Bug Fixes in Version 14.1Updated integer types in ni4882.h

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.

New 64-bit Application Interface

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.

Added NI-MAX and NI-VISA

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.

Support for NI System Configuration API

NI-488.2 now reports GPIB controller interfaces through the NI System Configuration API.

The following issues were resolved in NI-488.2 for Mac OS X, Version 14.1.

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.

Enhancements and Bug Fixes in Version 3.0.1Support for 64-bit Mac OS X Kernel

NI-488.2 for Mac OS X now functions when using a 64-bit Mac OS X kernel.

Support for GPIB-ENET/1000 Controllers

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.

Revised Method for Configuring GPIB Ethernet Devices

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.

Replacing NI Spy

NI Spy is replaced by NI I/O Trace.
