Sending Commands LeCroy 8901 GPIB interface

I have had decisive trouble in communicating with an IEEE 488
interface device, the LeCroy 8901A, with LabView. My problems range
from trying to enable SRQ on occurance of LAM (my system locks up
everytime I send the command string "A" to the 8901 using the labview
"GPIB Write" function) to even discerning from the 8901 manual what
exactly the TALK command really is!
If anyone has any suggestions or helpful websites I might visit, I
would be very appreciative.
Thanks,
Pete

I'm not familiar with the device but there is a driver for it here. Are you using it and having problems with that?

GPIB 488.2 Send command

Why is it that when I use the GPIB 488.2 Send command, using the string "ID", it sends the string over and over again? I just want it to send the string once.

The Send command should only send the string once. Could you possibly attach an NI-Spy log or a GPIB Analyzer capture to show us the problem?

Problems using 488.2 commands with Agilent 82357 interface

Hi, I need to send a large file to an instrument in chunks using the 488.2 commands sendsetup and senddatabytes. When I try to use these commands I just get an error saying 'NI-488: Error connecting to driver or device'. The interface works fine using visa. I’ve tried the obvious in checking that the bus address is correct and I believe it to be.
Anybody know what I may be doing wrong or if its possible to do it another way? I’m starting to wonder if its an issue with it being a non NI interface.
Thanks

Hi,
We have done trade-ins in the past with 3rd party hardware, and this may be an easy solution for you since we do have a USB-GPIB interface available that does Standard and HS gpib (you didn't say if you were using the A or B variant of the Agilent 82357.

I'd suggest contacting your local sales office (+44 1635 572400 for the UK) to find out if this is acheivable in your case, or to arrange a loan to see if that in fact fixes the issue and makes the option more practical.

What exactly is happening/failing when "GPIB Interfaces sequentially verified" FAILS?

I have an AT-GPIB/TNT+ card installed in my computer. It fails the "GPIB Interfaces sequentially verified" portion of the Wizard program. I am able to communicate (IBIC) with my instruments, so it appears that all is working well. I do have older non-compliant GPIB interfaces so the "Scan for Instruments" does not work. What exactly is failing in the Wizard and what can I do? I have windows 95.0.

Janet,
Typically when the installations fails the sequential verification, it is due to either a resource conflict or a device being connected to the board during the test. You can click on the failed interface to get a brief explination of what may have caused the error.
There are instances reported using the AT-GPIB/TNT+ board and Win 98 inwhich this error was reported even though there were no problems with the board's setup. Since you are communicating properly with the board through IBIC your board is functioning properly, and I would not be concerned with the error message.
As for your instrument, this is likely due to your instruments non-compliance to 488.2 standards. Whenever the Measurement & Automation Explorer does a "Scan for Instruments", it sends out the stri
ng "*idn?" (which is an IEEE 488.2 identification query string) to all of the devices on the bus. If you have older, non-IEEE 488.2 compliant instruments on your GPIB, then they will not recognize this string as a valid command. This will cause "Scan for Instruments" to fail.

GPIB instruments connected through Agilent USB/GPIB Interface can bee seen in MAX but can't communicate in labview

I have an Agilent 82357B USB/GPIB Interface connected to my computer.
Attached to that, I have two lock-in amplifiers (an SR830, and an SR
850). I would like to be able to communicate with them through GPIB.
I have downloaded and installed the software for the Agilent device
(Agilent IO Control), and I can see the interface and the two devices
in that software. Here's what is configured in this software, that I
can see:
The VISA interface ID is GPIB0, and its address is 0
The VISA addresses of the devices are GPIB0::4::INSTR and GPIB::12::INSTR, and the GPIB addresses are 4 and 12
In Measerment and Automation Explorer (MAX), I made sure that the
Passport for Tulip box was checked. Once it was, I could see the
devices in the Configuration window under Devices and Interfaces ->
Miscellaneous VISA Resources. There, I see GPIB0::INTFC, GPIB0::4::INSTR and GPIB::12::INSTR.
I can right click on either of the instruments, and "Open VISA Test
Panel" where I am successfully able to send commands and read from both
devices.
HOWEVER, when I am running an actual LabView program, I am unable to communicate with the devices.
For example, when I try to communicate to the devices through VISA,
using the 'Basic Serial Write and Read.vi' (while VISA Resource Name is
GPIB0::12::INSTR), I get an error:
Error -1073807331 occurred at Property Node (arg 2) in VISA Configure Serial Port (Instr).vi->Basic Serial Write and Read.vi
Possible reason(s):
VISA: (Hex 0xBFFF001D) The specified attribute is not defined or supported by the referenced resource.
When trying to communicate with them through GPIB (which is what I want
to do in the end), using 'GPIB.vi' I also get an error. Here, GPIB
address is 12, and I am just trying to give it the command *IDN?
GPIB Write returned error code:
EDVR: Error connecting to driver or device
What's going on?

You can use VISA Write and VISA Read. You just can't use the example called Basic Serial Write and Read because that is specifically for the RS-232 port. The GPIB-VISA is one of the shipping examples. Start the example finder and go to the search tab. Search for VISA.
Again, no you cannot use the GPIB functions with a non-NI controller. The low level functions for an NI board and an Agilent one are completely different. You can rewrite the driver to use VISA or you can rewrite it to use the low level functions that Agilent provides. You use the Call Library Function Node, I believe to access their GPIB driver.
I hate to say it but the $20 difference between the Agilent and the NI controller does not seem like much of a saving.

Problem with Get the current and voltage from HP Power Supply (HP E3631A), using the GPIB interface.

my USB device's power support is from the DC Power Supply ( HP E3631A)
I need to read using current from a DC Power Supply ( HP E3631A),via GPIB interface.
When I use the follow command.Why can't read the current value.My environment is in vc++ 6.0.

Can you tell me what the problem is ??

Hi neilchuang,
A read timeout error is usually caused by an error on the command string sent.
The first thing I would check is if the instrument requires a termination character at the end of each message (such as linefeed). I noticed in the Spy capture that the commands do not have a termination character attached. This means that the instruments never recognized that you completed the query command, it doesn't execute the requested action and as a consequence of that it doesn't have any data to return.
One question: Is the instrument detected by MAX when you scan for instruments?. If yes then you can assume that the GPIB software and hardware are properly installed. The scan for instruments sends the *IDN? (terminated by a linefeed). You can right-cli
ck on the instrument entry in MAX and select "Communicate with instrument". Notice that at the end of the command the linefeed is included (\n).
Double check with the instrument manual if the commands sent are the right ones.
Finally, there is an instrument driver available in the idnet library: www.ni.com/idnet. Search for 3631. Since you are working in C you can use the LabWindows/CVI Plug and Play driver. Even if you decide not to use the instrument driver, you can still use it as an excellent reference on how to program with the instrument.
Hope this helps!.

Why can I send command to my machine used MAX sometimes,but cann't I sometimes?

I'm developing a gpib interface for our machine using your nat9914 ,but when I send a command "*idn?" to my gpib interface used Measure & Automation,sometime communication was interrupt,this interrupt may appear one times when I communicate four times or more times or less times,Mearsure & Automation display "writing" or "Reading" and then display "EABO"

Hi PeiWen,
Are you using our NI-488.2 drivers? If so, which version? EAB0 is a standard GPIB error message:
The EABO error is usually the result of a timeout during a read or a write operation, but it can also be caused by calling the ibstop function, the ibclr function, or similar functions while an I/O operation is in progress. You may receive a timeout during write operations with a PCI-GPIB board, if the PCI bus mastering (an option in the BIOS of your computer) is not enabled. You may receive a timeout during read operations, if the instrument you are reading from did not understand the previous command, so it has nothing to write to you. There are a few reasons why the instrument may not have anything to say:
The message to the instrument may have been misspelled. For example, "*IDN?" is a common identification query for IEEE 488.2 compliant instruments. It is easy to misspell this message as "*IND?", which the instrument will not understand, so it will not generate a message string for you to read from the instrument.
The message to the instrument may contain a command that the instrument does not understand. For example, the "*IDN?" message from the previous example is only understood by IEEE 488.2 compliant instruments. If your instrument is an older, non-IEEE 488.2 compliant device, then it will not understand "*IDN?", so it will not generate a message string for you to read from the instrument.
The instrument may use a particular EOS (end of string) character as its termination method, but you may forget to append this termination character to your message. For example, if your instrument expects a linefeed as the EOS character, then "ID?" will not work, but "ID?\n" (where \n represents a linefeed in IBIC) will.
You may expect to see EOI (end or identify, one of the five bus management lines) as the termination method, but if the instrument does not set the EOI line when it finishes sending its message, any read operation that you perform will time out.
The above information, including explanations of other GPIB errors can be found at: http://digital.ni.com/public.nsf/websearch/2FA525A8585A92E9862566EE002A3755#EABO

N6705B connectivity via GPIB interface in UNIX

Hi
i had an N6705B device my requirement is like below
I need to control this device via an GPIB interface in linux PC.
for the above i am using an GPIB to GPIB cable and connected the N6705B and amy linux device.
Now i have to connect/login in to the N6705B device and do the settings like setting voltage for the DUT (IC chip) and collect measurement for various test scenarios of DUT.
For example i have to set the input voltage as 3.7v to my test device(which is an wifi device) and connect it to an access point(connection will be done manaully) so during the connection stage i have to measure the current consumed by the device (taken across power amplifer).
I think there are SCPI commands whcih i notice in the AGilent 14585 control software which do the same (the software support is there in windows 7 via an GUI), is there any posibility now this commands i can send to the agilent N6705B device by logging into it from a linux PC.
Thanks

Error 7 occurred at Open File+.vi:Open File,NI-488: Nonexistent GPIB interface

I did some clean-up of my computer and have been having issues ever since.
I'm not the one that did the programming; the person who did is long gone.
The VI loads fine but when I hit run I get:
Error 7 occurred at Open File+.vipen File
LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on Linux. Verify that the path is correct using the command prompt or file explorer.
=========================
NI-488: Nonexistent GPIB interface.
All the necessary VIs are available and I've tried changing all the file calls in the VIs to the new locations but the error is the same.
Any suggestions?
Thanks.

Error 7 is a generic file not found. If it is happening after cleaning up files, more than likely you moved some subVIs called in a main VI to a new location on your computer. If all the VIs are in a project, a possible solution would be to remove the vis in the project directory and add them back to the project as they may be pointing to a previous location where the files were once stored. Perhaps this is what Anon123123123 meant by "linking". Hope this helps.

As far you are using VirtualBox, your processor capabilities shouldn't counted (min from my own experience while setting up the virtual machine. Change the Domain Type under configuation node to XEN PVM and try again. Most probably the virtual machine will start running.
One more thing, enable promiscuous mode -> Allow allow with your network configuration (if bridged network is in use) for the VM Server prior you try to SSH into the virtual machine (your guest on VM Server)
All the best and post your test results

Populating list with connected GPIB interfaces

I'm working on the setup section of an APP in Delphi5.0 using the GPIB-32.DLL and am a little baffled. Ni supplied this little gizmo that searches for GPIB interfaces (not devices). I would like to emulate this functionality for my application in a setup wizard sort of way so the end user can simply select from a list of 'detected' interfaces. In looking at the DLL calls they all seem to require previous knowledge of the device location. So I'm wondering if there is a set range of possible Primary and Secondary addresses I can use to just loop through searching for an interface. I'm assuming here that anything that wouldn't toss a failure when sent a Pri/Sec Address would be a set of valid device ports. On that note...
are there some specific commands to issue that will return a string telling me exactly what it found on that Pri/Sec address?
Thanks!
CT

Ok.. I made some progress. Using SendIFC and ibfind, etc, watching NiSpy I have determined this is coming back as an Integer and other Ni applications use the Init_DA_Brds to obtain a translation of the integer to descriptive title. However I don't have access to that and the only reference I found of the device list codes is from 1999 which does not include some of the newest hardware including the USB based devices.
Is there a newer list of product codes available?

Will data transfer in parallel in GPIB interface?

Hi all,
I have two devices (supporting GPIB) connected in serial and connect to the GPIB interface card. Those two devices have two different addresses and I use VISA module to send data in parallel. But the GPIB cables are connected in serial, so does it mean it will be locked when transferring data to one device? I think GPIB transfer rate is not that low (about 1Mbyte/sec) but it takes so long to transfer 500kB to the device (about 45sec).
Solved!
Go to Solution.

Dennis_Knutson wrote:
The GPIB bus does not support parallel data transfers so you are certainly sending it that way.
You have not provided the instrument or your code so it.is impossible to say anything about your transfer rate but the 1MB is a theoretical maximum that you seldom achieve in the real world.
Here is the link for the device I have
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9294659CE034080020E748...
The code is not written by me, but I extract the core part and show as below
You will see that there is only one GPIB interface (0), both device 1 and device 2 are connecting to the same card. The data sending to device 1 and device 2 is about 400kB (shown as xxxx.xxxxx. and yyyy.yyyyy).

Error 7 file not found NI-488 nonexistent GPIB interface

I'm trying to use an accelerometers with cRIO through NI 9234. I'm using an Fpga example which I modified according to my characteristics. Till here, everything is OK, nevertheless when I open the Fpga vi file and I run it compilation is not finished and it si returned the next message:
Error 7 occurred at NI_LVConfig.lvlib:Load.vi
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS X, and / on Linux. Verify that the path is correct using the command prompt or file explorer.
=========================
NI-488: Nonexistent GPIB interface.
I have attempted several possible solutions paste in the forums but I have not solved the problem

Are you using any filepaths in your application? Does the VI have any subVI's? The error you are getting is triggered by a reference to a filepath. Does your application call a file at any point? You need to make sure that all of the filepaths your application is referencing are in fact the correct location for these files.
Also, you may need to check your Open FPGA Reference VI, which loads a bitfile. Usually, this bitfile relies in the same directory as your LabVIEW Project.
Hope this helps!!

Sending commands via usb port?

i'm looking to send commands over a usb cable to a device via xcode or cocoa. i know leopard did away with rs232 commands, so i'm looking for some sample code that sends a command via objective-c over a usb cable.

From Cameron Forbes of US FTDI tech support:
Ed:
After you install the FTDI D2XX drivers for Mac OS X (Intel Macs):
http://www.ftdichip.com/Drivers/D2XX/MacOSX/UniBin/Universal%20D2XX0.1.4.dmg
Add the following links (from Mac OS X Installation Guide):
· Start a Terminal session (Go > Applications > Utilities > Terminal)
· Copy libftd2xx.0.1.0.dylib to the /usr/local/lib directory (cp Desktop/D2XX/bin/libftd2xx.0.1.0
/usr/local/lib)
· Change directory to the /usr/local/lib (cd /usr/local/lib)
· Create a symbolic link to the library (ln -sf libftd2xx.0.1.0.dylib libftd2xx.dylib)
The example code is located at:
/desktop/d2xx/Samples

Send command from my own application

Hi,
I have some problem to send commands to �Instrument�, which connect to computer via GPIB card.
I use my own application with advanced script language and 16-bit GPIB ISA card, OS � Windows 2000. I have send to �Instrument� command as string.
Here is fragment of code :
�
LoadLib(�gpib-32.dll�) <-- Loading DLL
RunLibFunc(handler, , ) <-- Running function from DLL
�
- the name of function from DLL � should be something like �Send�
- array of arguments for the function : GPIB card ID, GPIB address of �Instrument�, my string, and something else �
Please Help me to find exactly commands syntax and the way to use it.
Thanks in advance

Dennis is correct, you can find information about the functions in the help file.
You can also find a list of functions in the "NI 488.2 Function Reference":
