Using NI-VISA 4.2Supported Platforms
NI-VISA for Macintosh supports the following platforms:
VISA Support for Multiple GPIB-VXI Controllers
NI-VISA supports multiple GPIB-VXI controllers in a single system. Because the National Instruments GPIB-VXI controller ships with a primary address of 1, NI-VISA automatically searches for any GPIB-VXI controllers at that address.
If you have changed the primary address (for example, if you added a second GPIB-VXI controller to your system, and set the address of the second controller to 9), or if you have a GPIB-VXI controller from another vendor, you need to use the NI-VISA Configuration Utility so NI-VISA can find it. This application's path is /Applications/National Instruments/NIvisa/VisaConfig. While in the Resource Editor, click the Add button to add a new resource. Specify a valid resource name for the new controller, such as GPIB-VXI2::0::INSTR. You will then be prompted for the GPIB board number and the GPIB-VXI's primary and secondary addresses. For most users, the only number that will change (from the default selections) is the primary address (for the above example, you would change it to 9). Click OK to add this new resource, and then select the File»Save menu option to save this to the NI-VISA database.
If you are using a GPIB-VXI command module from another vendor, you also need to obtain and install that vendor's VISA GPIB-VXI component.
If you have a GPIB device at primary address 1, and that device does not recognize *IDN?, you should disable the GPIB-VXI auto-detect feature in VisaConfig on the Settings tab.
Installed Files and Paths
There are three main locations where NI-VISA installs files.
The local /Library/Frameworks folder contains the VISA.framework folder. This folder contains all needed headers and supporting Passport libraries that NI-VISA uses.
In the local /Applications/National Instruments folder, there is an NI-VISA folder. Included here are the user and programmer manuals, as well as several groups of C examples using NI-VISA. This NI-VISA folder also includes a graphical utility called NI-VISA Configuration to configure VISA options.
Finally, the /Library/Preferences folder contains an NIvisa folder with .ini files. These files are used for NI-VISA settings and status codes.
VISA Probes for LabVIEW
The VISA probes for LabVIEW 7.0 and higher greatly extend the amount of relevant information displayed when using LabVIEW probes on VISA refnums. They are used automatically by LabVIEW in place of the generic probe when they are installed.
The NI-VISA installer installs the probes for LabVIEW 7.1 and higher. However, if you are using LabVIEW 7.0, you can download and install them yourself. To install them, download them from ftp.ni.com/support/visa/labview/probes/ and copy them into <LABVIEW_DIR>/vi.lib/_probes/default/VISA/, where <LABVIEW_DIR> is the installation directory of LabVIEW 7.0.
Known Issues
Running NI-VISA under Rosetta with the PXI/PCI Passport enabled will cause the application to terminate. If you wish to run under Rosetta, disable the PXI/PCI Passport. This may be done using the NI-VISA Configuration Utility.
Improvements and Bug FixesNI-VISA 4.2
Bug ID 46Q632QK. Each VISA session to a TCP/IP INSTR (VXI-11) resource created a new device link with the device even when using an identical device name. The TCP/IP INSTR device is more prone to run out of device links in this scenario. Now TCP/IP INSTR sessions share device links for the same TCP/IP device when an identical device name is used.
Bug ID 48ACG54U. viScanf and variants did not correctly support the %b enhanced format code in some cases. This is fixed.
NI-VISA 4.1
In the NI-VISA Configuration Utility, added options for 'Show all devices accessible to VISA' and 'Show peek/poke calls in NI Spy'.
In the NI-VISA Driver Wizard, it would not install the INF files for users without root access and not display any errors. Now it warns that root access is required to access the installation feature.
In the NI-VISA Configuration Utility, IP address entry was not validated. This is fixed.
In the NI-VISA Configuration Utility, dynamic resources such as USB devices were not removed and re-added correctly on refresh. This is fixed.
For GPIB INSTR resources, VISA would set only the GPIB I/O time out and not the GPIB serial poll time out. The serial poll time out is used in viReadSTB. This is fixed.
For GPIB INSTR resources, only one call to viWaitOnEvent could be outstanding at any given time. This is fixed.
Calling viFindRsrc with a non-empty, all-whitespace expression string would cause VISA to crash. This is fixed.
Calling viFindRsrc with an expression string that contained two sets of double quotes would not work. This is fixed.
For USB INSTR resources, viReadSTB could fail with a time out error on some devices that are not completely compliant with the USB TMC specification. This is fixed.
In LabVIEW, if the I/O Filtering option is set to URL format, local resources were not included in the I/O control list. This is fixed.
NI-VISA 4.0.1
Added support for the PXI/PCI Passport on the x86 architecture.
Added native support for the NI-VISA Configuration Utility on the x86 architecture.
NI-VISA 4.0
Added support for Mac OS X on the x86 architecture, aka Mactel.
Added support for 64-bit data transfers in register-based operations, to support the VISA 4.0 specification.
Added support for DTR/DSR flow control. The Agilent 34401A requires DTR/DSR flow control when used via Serial. Note that not all Serial port drivers on the Mac support DTR/DSR. We have tested the Agilent 34401A with NI-VISA 4.0 using the Keyspan USA-19HS and verified that it works properly.
The I/O control in LabVIEW 8.0 would not always honor the parameters you specified in the filtering dialog, depending on the order in which you made changes. This is fixed.
viScanf would crash when reading indefinite-length block data. This is fixed.
For ENET-Serial INSTR sessions, framing errors were occasionally not detected. This is fixed.
Improved performance of NI Spy.
For TCP/IP SOCKET sessions, re-enabling the termination character between read operations would incorrectly flush the internal buffer. This is fixed.
For TCP/IP SOCKET sessions, reading less than the entire amount of data that the device sent would not work correctly for asynchronous read operations. This is fixed.
NI-VISA 3.5
For TCP/IP INSTR sessions, viWrite would fail if the transfer size was more than 8 KB. This is fixed.
Significantly optimized PCI interrupts and block moves.
Significantly optimized calls to viFindRsrc and viOpen for all interface types.
For Serial INSTR sessions, a call to viSetBuf, which did not modify the buffer size, still returned VI_SUCCESS. viSetBuf now returns a warning indicating the operation is not supported on the current platform.
NI-VISA 3.4.2
In certain circumstances, an application that uses NI-VISA may crash while exiting. This is fixed.
NI-VISA 3.4
The VISA Driver Development Wizard is now supported on Mac OS X. It is in /Applications/National Instruments/NI-VISA. Previously, the wizard was supported on Windows only.
For USB RAW sessions, communication with nonzero control endpoints is now supported with the use of VI_ATTR_USB_CTRL_PIPE.
For USB RAW sessions, the default setting for VI_ATTR_USB_END_IN has been changed from VI_USB_END_SHORT to VI_USB_END_SHORT_OR_COUNT.
For USB RAW sessions, viReadAsync would fail if the transfer size was over 8 KB and not a multiple of the maximum packet size of the endpoint. This is fixed.
For USB RAW sessions, viWaitOnEvent on VI_EVENT_IO_COMPLETION would not indicate successful completion in all cases on reads. Because of this, VISA Read in LabVIEW would not work correctly in asynchronous mode. This is fixed.
For USB RAW sessions, changing the USB Alternate Setting on a USB Interface number other than 0 would fail. This is fixed.
For USB RAW sessions, VI_ATTR_USB_BULK_OUT_STATUS, VI_ATTR_USB_BULK_IN_STATUS, and VI_ATTR_USB_INTR_IN_STATUS would not indicate a stalled pipe. This is fixed.
Performing asynchronous I/O to a remote VISA resource would return an incorrect transfer count and/or data. This is fixed.
For TCP/IP SOCKET sessions, VI_ATTR_SUPPRESS_END_EN set to VI_TRUE did not work in all cases. This is fixed. The default attribute setting for VI_ATTR_SUPPRESS_END_EN on TCP/IP SOCKET sessions is now VI_TRUE.
For PXI INSTR sessions, when enabling for VI_EVENT_PXI_INTR using VI_QUEUE, viDiscardEvents did not work properly. This is fixed.
For PXI INSTR sessions, viPeek16/32 and viPoke16/32 did not perform a byte swap even though the system byte order and PCI byte order does not match. This is fixed.
NI-VISA 3.3
The PXI/PCI INSTR Resource is now supported on Mac OS X. PXI-specific functionality is not supported at this time. You must generate an INF file for your PXI/PCI device with the VISA Driver Development Wizard on Windows using NI-VISA 3.3 or higher. INF files generated with older versions of NI-VISA are not supported on Mac OS X. You can find installation instructions in the generated file. This is a new feature.
The remote NI-VISA server is now supported on Mac OS X. This is a new feature.
For USB RAW sessions, now interrupt-out endpoints may be used for viWrite.
For USB RAW sessions, viReadAsync is now implemented.
Opening a VISA session to a resource and then exiting the application without closing either the VISA session or the Resource Manager could crash the application. This is fixed.
viFindRsrc would crash when given long strings that use remote NI-VISA. This is fixed.
Calling viMoveAsync on a remote VISA session would return an error. This is fixed.
For Serial INSTR sessions, viClear previously would flush (discard) the I/O buffers and then send a break. According to the VISA spec, VISA must flush (discard) the I/O output buffer, send a break, and then flush (discard) the I/O input buffer. This is fixed.
viScanf and variants did not support the %u identifier for arrays. This is fixed.
viPrintf and variants did not support the %zy and %Zy identifiers for floating point data. This is fixed.
viPrintf and variants previously generated NaN, +Inf, and -Inf. It now generates NAN, INF, and NINF, respectively.
viScanf and variants did not correctly interpret the input values NAN, INF, and NINF. This is fixed.
The NI-VISA Configuration Utility now supports adding arbitrary aliases.
NI-VISA 3.2
Added complete support for USB (both RAW and INSTR).
Calling viPrintf on a remote VISA session would return VI_ERROR_IO instead of VI_ERROR_RSRC_LOCKED when the remote resource was locked. This is fixed.
NI-VISA 3.1
Reading data from a Serial port was slow. The performance has improved.
Using the Serial Break VI from LabVIEW did not work with remote NI-VISA. This has been fixed.
For a Serial INSTR resource, if a parity or framing error occurred, NI-VISA would not return the correct error condition. This has been fixed.
In the VisaConfig application, using the Browse button in the Enet-Serial dialog would not work. This has been fixed.
Calling viOpen on a remote NI-VISA resource did not honor the openTimeout parameter. This has been fixed.
Calling viFindRsrc on a remote system would cause LabVIEW to later crash when you exit. This has been fixed.
Calling viClose on an Ethernet resource would leak a socket handle. This has been fixed.
The global attributes on a GPIB INTFC resource were not properly shared across sessions. This has been fixed.
Using the system call fork on a process with VISA loaded would sometimes cause the forked process to hang. This has been fixed.
NI-VISA 3.0
When you open a VISA session to GPIB0::INTFC and immediately query the attribute VI_ATTR_GPIB_SRQ_STATE, it previously returned the value VI_STATE_UNASSERTED. It now returns VI_STATE_UNKNOWN, because the SRQ line cannot be monitored if the interface is not yet CIC. The correct state is returned after calling viGpibSendIFC.
For a TCPIP INSTR resource, calling viTerminate did not work correctly.
For a TCPIP INSTR resource, calling viRead or viWrite with a large buffer occasionally would return an error without transmitting the entire buffer.
For a TCPIP INSTR resource, opening and closing sessions to multiple host addresses would cause NI-VISA to crash.
For a TCPIP INSTR resource, calling viLock with a timeout longer than the I/O timeout for that session could cause NI-VISA to return VI_ERROR_TMO.
For a TCPIP SOCKET resource, viReadAsync was not implemented. Now it is.
For a Serial INSTR resource, viOpen will now open a port if the process that had been using that port exited ungracefully (such as with <Ctrl-C>). The previous behavior had been that viOpen would return VI_ERROR_RSRC_BUSY.
For a Serial INSTR resource, if you enabled RTS/CTS flow control and then manually tried to set the state of the RTS line, some operating systems would generate VI_ERROR_NSUP_ATTR, while others would return VI_SUCCESS, but not actually modify the state of the line. Neither of these behaviors was correct. Now NI-VISA will return VI_ERROR_INV_SETUP in this case on all operating systems.
For a Serial INSTR resource, if a binding existed to a valid file/device but that file/device was not really a serial port, NI-VISA would not close the handle. Repeated calls to viFindRsrc or viOpen would cause the process to eventually run out of file handles. This has been fixed.
If you had a GPIB device at primary address 1 that generated a response to *IDN? that was longer than 100 characters, viFindRsrc would occasionally crash. This has been fixed.
viFindRsrc would crash on a complex expression with multiple | symbols. This has been fixed.
The viScanf %# modifier will now output the number of characters put into the buffer excluding the terminating null character. This applies to the %#s, %#t, %#T, and %#[] modifiers. NI-VISA treats the maximum array size (specified on input) as the total buffer size including the terminating null character.
Calling viFindRsrc repeatedly when logged in as root would eventually run out of file descriptors. This has been fixed.
The attributes VI_ATTR_MANF_NAME and VI_ATTR_MODEL_NAME are now correctly implemented for GPIB-VXI regardless of whether NI-VXI is installed.
The maximum simultaneous number of GPIB-VXI controllers supported by NI-VISA has changed from 10 to 32.
For a Serial INSTR resource, the internal modem is now correctly detected.
For a Serial INSTR resource, during a viFindRsrc, when a previously found serial port was detected again, the scan would not proceed to find any new serial ports. This has been fixed.
For a Serial INSTR resource, a call to viOpen when the corresponding serial port did not exist returned VI_ERROR_SYSTEM_ERROR. This return value has been corrected to VI_ERROR_RSRC_NFOUND.
When calling viWaitOnEvent repeatedly with a timeout of 0 (immediate), some interfaces and event types would still consume excessive CPU time. Now doing this will yield the CPU regardless of the interface or event type.
For a GPIB resource, the operations viWriteAsync and viReadAsync did not support true asynchronous operations. The data would still transmit and receive, but NI-VISA did it synchronously. This has been fixed.
viFindRsrc would return VI_ERROR_INV_EXPR if the expression exceeded 255 characters. Now it will accept resource expressions of any length.
Calling viFindRsrc would always assert REN on each GPIB board after finding devices. Now viFindRsrc will reassert REN on each board only if there is at least one open VISA INSTR session on that board.
For a TCPIP SOCKET resource, using viRead with termchar enabled was much slower than reading the exact number of bytes. The performance of using termchar with viRead is now much better than it was.
Calling viFindRsrc would return serial ports even if they were explicitly disabled in the configuration file.
