How to use a GPIB card's LabView drivers to communicate with the card?

I have an axiomtek AX4810P PCI-GPIB card and i have aquired LabView drivers from the manufacturer.
This has put VI's for the GPIB functions on the 'user palette' but i can't work out how to use them to communicate with the card. can anyone help? please.

LS,
Thank you for contacting National Instruments.
Unfortunately, since you are not using a National Instruments GPIB card, I do not have access to the drivers that were provided to you by your card's manufacturer. I would suggest contacting Axiomtek directly to obtain support using their drivers.
However, I did write a small VI that demonstrates how to use similar National Instruments drivers with a National Instruments GPIB card. Keep in mind, this example VI is not intended to work with your particular card. The drivers you obtained from Axiomtek may have similar functions, however, and you can use my VI as a guide. My VI allows you to send a command to an instrument at address 2 on the GPIB card.
Hope this helps!

How to use a C# dll in Labview?

How can I use a C# dll in Labview 8.2? With the "Import Shared Library" Wizzard I need the header file which I don't have. Is there another way
to use such .dll to import the functions created in C#?
Thanks in advance
Norick

Norick,
afaik there is no tool which provides you the possibility to create something like an instrument driver for .NET assemblies.
Maybe we should take a look into terminology:
- Instrument driver: This is a set of functionality, which provides the user with an easy to use API for a special instrument. Very often, the driver itself is written in C/C++ and provided as a DLL.
- "Import Shared Library" Wizard: This wizard enables the user to create an own API for any C/C++ DLL (or compatible) for LabVIEW. This wizard requires the information on all exported functions; this info is contained in the header file. The result of the wizard is a set of VIs containing one Call Library Function Node each for each exported function.
- .NET assembly (extension .exe OR .dll): This can be compared to ActiveX. So the way to program with .NET is similar to ActiveX. Maybe you want to take a look into the examples of LabVIEW regarding .NET...
- Global Assembly Cache (GAC): All assemblies contained here are registered in the system. Every application can easily work with assemblies contained here.
- Private assemblies: This would be the way to work with .NET assemblies which are built on your own. You have to select the .DLL-file itself and make sure that the file can always be found in the same (relative)folder of your application.
hope this helps,

How do I use multiple GPIB cards in one computer?

I have two GPIB cards installed in my computer. One has aprimary address 0 and the other is 1. The card with adress 0 works fine but when I try to communicate with some instrument via the second card, the instructions are not carried out. However MAX ha detected the presence of instruments on both the cards, but it is only that when the second card(address 1) is used the intructions are not carried to the instrument. Please advise on how to select the card while sending an instruction? Or is it that I can use only one card at a time??

When you say that your commands aren't carried out, could you describe what commands you are sending, and what error is being returned?
When you say that you cannot communicate with the second instrument, are you using the 488.2 Communicator in MAX?
Did you make sure that all the settings for the second GPIB board in the properties page are correct?

GAIN PHASE Data collection from HP4194 using a GPIB card?

I'm trying to collect gain and phase data on a HP4194 using a GPIB card. I'd like to collect this data and run it to an MS Excel spreadsheet. Does any one have any VI's that do this??? So far, I haven't been able to find any commands that read each of the 401 elements to labview.
HERE'S AN EXAMPLE OF DATA I WANT TO READ:
http://www.tec.ufl.edu/~shailu/labview/4194a/4-pt/505/II/archive/pxfn1.txt
Please email me at [email protected], if you have a solution. Thanks.

That sounds like a bit of LabVIEW coding. Here's some resource that will help:
-The instrument driver for this device is available at ni.com/idnet.
-LabVIEW has a WriteToSpreadSheet.vi on the File I/O function pallete.
-The Programmer's Reference for the 4194 gives the strings to send of the GPIB bus.

I'm sorry, but there is nothing that I can do to help you with this situation. I don't know why, but many people have problems when they try to buy gems in the Clash of Clans game. Personally, I wouldn't touch the game with a ten foot pole, but that's just my opinion.

How to use sbi debit card for itune purchase

Hi, Cannot communicate with other instrument devices (Using AT-GPIB card)

Using AT-GPIB card to communicate with instruments that the running program is in C. After installed 488.2 software and test Hardware Diagnostic Test and Software Diagnostic Test. Everything is OK but after I run execute file the errors appeared. They displayed "GPIB cannot find Amplifier,or Unidex". My main task is transfer the AT-GPIB card from PC 386 to PC windows 98. Please help me to solve these problems. May I still use the old execute file to put in drive C in new PC Wins 98 and run that program. Thanks

Hi,
It is hard to say what this could be. Everything tests OK so it is likely that your card is correct. Does MAX detect the instruments? I am not familiar with that error message. Is it the output of some custom program or the driver itself? It seems like it is not a driver level problem, but it is hard to say given the information.
By "May I still use the old execute file to put in drive C in new PC Wins 98 and run that program" do you mean keep an old application? If yes, then you should be able to use the old applicatoin with teh win98 driver. If you are refering to the driver itself, then no. You will need the windows 98 driver. This can be found at http://www.ni.com/support/gpib/versions.htm
Hope this helps out.

AThe fixed size arrays in your structure are inlined byt the C compiler. This means they are not an array pointer (and definitely never a LabVIEW array handle) but rather LOG_CHANNELS amount of unsigned ints and floats directly embedded in the structure. In LabVIEW terms this is most easily represented as a cluster with LOG_CHANNELS elements inside the main cluster.
So basically your uAsigndPhysCh needs to be a cluster with LOG_CHANNELS elements of unsigned ints and fRange, fReadout, fMax and fin are clusters with LOG_CHANNELS single precision float values, and then sChID is a cluster with 32 * LOG_CHANNELS chars and sChUnits one with 16 * LOG_CHANNELS chars.
However I would personally rethink this strategy. This huge cluster monster is passed into PostLVUserEvent() each time and copied into the event data on every event, causing quite a bit of overhead that way. Is it really necessary to post all this data every time?
Also you have commented out uDAQMode and bControllerActive in your C structure but included it in the LabVIEW cluster which will certainly throw off your data. Last but not least the b prefix would probably indicate that you are only using that element as a boolean value, so why not consider to use bit fields there? In LabVIEW you can easily seperate those bitfields by either translating the resulting uInt32 into a boolean array or even more efficiently use boolean logic to detect the bits.
And in order to let LabVIEW react on a user event you have to create that user event with the correct datatype (your cluster monster) and then pass the user event refnum to your DLL. This DLL then calls PostLVUserEvent() with the user event refnum as first parameter and a pointer to a data structure that matches the LabVIEW user event datatype EXACTLY whenever it wants to post an event to LabVIEW. The user event is also registered in an event structure in LabVIEW which will then get triggered everytime your DLL posts an event by correctly calling PostLVUserEvent().

How to use DG Gryphon Toolkit to communicate with the vehicle using ISO 9141-2 protocol

Hi All,
I am trying to use the Dearborn Group's Gryphon Toolkit to communicate with the vehicle & read some parameters. I have downloaded the toolkit from here. I have got the DG's S3 device. This device supports different protocols. But I could not proceed with the protocol selection using the Gryphon LabVIEW Toolkit. It would be nice to get some guidance here. Is there anyone who had worked with the toolkit? Any help would be greatly appreciated.
Thanks,
Priyadarsini S

Is there anybody who had had exposure to this toolkit? How do we use the toolkit, for eg. to read Engine Coolant temp? I do not see a place where I can specify the PID number. Also is it really important to know a protocol completely by which Gryphon toolkit will communicate with a vehicle - Or just the knowledge of the Gryphon Communication protocol enough? It would be great to have the answers as soon as possible.
Thanks in advance,
Priyadarsini S

2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share

2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share
--break--
So we are entirely new to Apple products. I'm an IT guy, but have always been a windows user.
So the Ipad with Retina Display is to be mine (and will use it at work for notes, organization, etc)
The MINI is for the wife.
But, are we allowed and can we.. buy an app and share that app between both devices? IE. Can I buy a copy of Angry Birds for the House and both Ipad's use that single purchase? and if so, can we still run the Ipads seperate other than to share the apps purchased. IE my facebook and email set up on mine and hers on her ipad mini?
When I finally find a note taking app I like, can I share it on her ipad, without her having all my work files, etc?
Thanks for helping out the apple noob. Hoping for a great experience, and anticipate droping $100 in apps the first day.. just don't want to do that twice. If this is against the usage policy, thats unfortunate but good to know. (I mean we can share stuff on PC as long as its in the same household)
thanks again (explanations or links are fine)

There are a number of Apple services: iMessage, FaceTime, iCloud, Game center, Find My iPad, etc.
Now, to share apps, music and books you need to have the same Apple ID:
iPad's Settings > iTunes & App Stores > Apple ID > Your purchasing Apple ID.
For the other service, your wife should have her own Apple ID.
All she needs is a valid e-mail address, apply Apple ID below:

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.

We have a corporate iPad in our auto showroom to show guests how to use features on their vehicles. Someone locked it with their account. It was not an employee. How can I get in? I did a restore of the software already?

Gather up the proof that the dealership is the original purchaser of the iPad,
and take the iPad & that proof to a physical Apple store for possible assistance.
It is highly suggested that you make a genius bar appointment to avoid delay
at the store:

If no Apple store close by, get the information mentioned above and contact

THE use of the apple support is a mess also.

What is wrong with this maverick OS?

The only people who can possibly assist you with this is Apple Customer Relations, call your local Apple contact number and ask for Customer Relations then explain your situation clearly and politely (be firm but don't rant).
You might want to investiage what the local laws are regarding defective goods and 'fit for use' definitions on warranties etc. Consumer Protection can be a useful tool to use or bargain with if needed ...

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(
Have u ever tried to do some things like this?
