S: cheap LabView compatible GPIB-IEEE-488 Card

Hi Newsgroup,
i'm looking for a cheap GPIB-IEEE-488-Card (LabView compatible) to control a
climate-chamber with LabView 6.i. As the climate-chamber was build more than
ten years ago, i don't expect it's interface to be compatible to the
IEEE-488.2 standard.
Following information about the interface occur in the manual: IEC-bus, IEEE
488 plug connector
Is there a downward-compatibly form IEEE-488.2 to IEEE-488?
Does anybody know where i can buy such a card for few money?
I've found a Dealer in Germany (where i come from) with the following offer:

rame=unten&Src=http://www.quancom.de/qprod01/deu/pb/gpib_1.htm
For me it seems to be quite inexpens
ive, but i have few experience within
this range. Therefore I would be glad, if you could help me. My boss would
not appreciate if spend a lot of money for a card, which does work together
with the climate-chamber.
Greetings

Les's answer about 488 is right on. 488.2 is just a superset of the original 488 - nothing about the electrical interface has changed. You question about low cost cards has a different problem however. The GPIB functions in LabVIEW will only work with an NI card. If a vendor offers a VISA driver for their card, then the LabVIEW VISA functions will work but I have had some problems with very old instruments and VISA. If the vendor offers GPIB drivers for LabVIEW, then use those. If all they have is a DLL that you need to call, then you've got a lot of software development ahead of you. All of this means is that the cost of the hardware is just a part of the overall cost of a project. If you manage to save $100 on the board and then have spend a week or two o
n the basic GPIB software, you really haven't saved anything.

Communicating between GPIB IEEE 488-1978 Instrument and LabView

Hi,
I'm currently trying to convert some old BBC BASIC Code into Labview 6.1.
The BBC Computer has a GPIB Comms Unit attached to it to communicate with an old Marconi Instruments Microwave Counter 2440 using GPIB IEEE 488-1978.
I am currently trying to get Labview to communicate with the Counter using GPIB 488 vis and a NI GPIB 488.2 Card but I'm not able to get anything out of the Counter or get MAX to even acknowledge the equipment exists.
I was wondering if anyone out there knows if it is possible to communicate with a GPIB IEEE 488-1978 instrument in Labview 6.1 (or any other LV Versions) and if it is, does anyone have a driver for the instrument (Marconi Instruments Microwave Counter 2440 circa 19
84) or having any helpful tips on the protocol for talking to a IEEE 488-1978 instrument.(I have some previous experience using VISA.)
Many Thanks in Advance for your help.
Sammy Mason

I have done this with several instruments. It is best to get a hold of the manual for this instrument and see what commands it uses.
MAX will not find this using the *IDN? query. In MAX, open the "Communicate With Instrument" window and type "ID?" (without the quotes), and hit query. You should get some basic information back from your instrument.
I use GPIB Read and GPIB Write most often. Your instrument probably doesn't support much else. Maybe Clear and Poll.
Be careful if you are using a newer, faster computer. There are Knowledge Bases and Discussion Forum topics that discuss the problems that can arise. To prevent these problems, I created my own Read and Write VIs. They just have a few milliseconds delay before the read or writ
e takes place

I need help regarding GPIB(IEEE 488)

Is there any code you can give or advice regarding manipulation of GPIB card... I need to create a java program which controls an external hardware thru GPIB card...(only GPIB slot is available).... Any help is deeply appreciated... Thank you...

What kind of accounts do you need to reset? IMAP or POP accounts using one of the many web-based messaging systems? An Exchange server account? Were they working and now just not working any longer?
You're going to have to be a little more specific in what you need...

How can you interface IEEE 488 bus with labview

Hi
How should I proceed to interface labview with an instrument (an impedence analyser with a IEEE 488 port) and labview through a IEEE 488 interface card in the PC.
Thanks
Mal

Hi,
You hava a group of functions to do that. Go to Instrument IO --- GPIB.
There you can find the tools you need to comunicate with an instrument via GPIB.
You can also use MAX (Measurement and Automation Explorer) to test your comunication before implementing it in LabVIEW.
Hope this gets you started,

Hameg power supply HM7044 ieee 488 (GPIB) device control

Dear All,
I have a power supply (Hameg HM7044) with a GPIB interface.It seems that there is no VI to control it in the HAMEG or the ni websites.
Since i am new to this kind of interface i have two questions.
-if i connect the device how do i know the address it is in.
-is there a general VI to interact with GPIB -ieee 488 devices?
thank you in advance,
thodoros

Well, there is a driver here but it is for RS-232 and for some stupid reason, they have password protected the VI. That should deserve a nasty message to them.
First, if you use an NI GPIB controller, you will get a program called Measurement & Automation Explorer (MAX). As part of the installation instructions, you will do a 'Scan For Instruments'. This will return a list of GPIB addresses for all of the connected instruments. Second, the information for setting the GPIB address is going to be in the instrument manual. If you don't have a manual, get one because you can't do a thing without one.
To communicating to GPIB instruments, the recomended API is VISA. The majority of the time, all that you will need is a VISA Write and a VISA Read.
You can learn some of the basics at the Instrument Control Fundamentals page.

Can IEEE 488.2 Labview software/drivers used on a IEEE 488.1 instrument

I have a IEEE 488.1 device but am using a IEEE 488.2 Labview software/driver package. Measurement and Automatiion
tells me that the IEEE 488.2 board is working properly but there is no communication between the board and the device.
Is IEEE 488.2 downward compatible? If not, is there any remedy rather than getting a new board or getting a new instrument
with IEEE 488.2 software?
Thanks.
Mark

Hello,
In my application I am conducting a pressure test, Here am using DMA Make Air Data Test Set witch I am interfacing to the PXI system through GPIB.
In MAX the particular GPIB address is detected but if i write a query "*IDN?" it did nt respond.
To debug this issue I used NI 488.2 Interactive control when i started communicating with the instrument it throws error such as EAB0 and status as TIME0 and CMPL
Here the Instrument DMA make MPS31C is 1EEE 488.1 Compliant.and NI 488.2 Ver 2.52
Please find the attached operation manual and Device communication manual of the Air data test set
Please suggest be a solution for this issue.
Waiting for a quick reply
Regards
Lingaraj

Is a PCI-488.2-1M card backwards compatible with the 488-1975 standard?

Is a PCI-488.2-1M card backwards compatible with the 488-1975 standard?

IEEE 488-1975 is one of the early revisions of the IEEE 488.1 stardard, other revisions include 488-1978 and 488.1-1987.
Because the original IEEE 488 document contained no guidelines for preferred syntax and format conventions, work continued on the specification to enhance system compatibility and configurability among test systems. This work resulted in a supplement standard, IEEE 488.2.
So, both 488.1 and 488.2 support 488-1975
I checked the link and it is fine, make sure you have the right web browser settings.

How to use labview to talk to PC ELITE IEEE 488 Interface

hi,
I am trying to talk to EAC 300HR and EAC 2000 controllers using PC ELITE IEEE 488 Interface throguh labview. It would help if someone cpould give me a clue ablout how to start with it??
ABhishek

Hi,
As with any hardware, this board should come with its device driver. The device driver allows you communicate with the device from your application.
Also, the device driver needs to provide Language Interface files. For example, NI-488.2 (NI's GPIB driver) provides header and library files for Visual C, .bas files for Visual Basic and VIs for LabVIEW. Each of these allows you to call the GPIB function from any of these programming environment.
You should check the documentation of you board and determine what Language interface files it provides. Look in their website for any LabVIEW drivers.
If the driver does not provide LabVIEW drivers, you can still use the driver if it provides a dll where you can call the driver function. In labVIEW yo
u can use the Call library node to directly call dll functions.

NI IEEE 488.2 and Borland C++ Builder 1.0

I have an NI IEEE 488.2 card connected to a HP DVM. I am using this as a
test bed to develop the 488.2 base code for other projects. The rack system
normally runs off of LabVIEW 6.1.
I will eventually move this code over to run an old prober. When I initiate
the program level commands, ibdev or ibwrt for example, through WIBIC I have
no problems. Neither setting up or reading from the meter. When I utilize
these very same commands in the compiled software I get nothing. It's as if
the program isn't even going out and looking for the card.
I have called the decl-32.h and the NI provided .obj file as the language
translator, but nothing.
Any help?
Seth

Diego,
Thanks for the reply. I fixed the problem. It was the machine I was working
on. I had our IT guy give me a more up to date machine and comm. commenced
nicely. I've only written a small bit of C++ and like the Builder
environment. There never was anything wrong with the card, the NI 488.2 or
NI 488 commands.
But, I'm moving on to our LabVIEW 6i. As an engineer, I was appalled to
find that we owned a full version of 6i Development System and are still
testing our production devices by hand.
Being that I am learning LabVIEW, you are sure to hear from me quite a bit.
Any help as to the location of some nice info on communicating with Excel
from LabVIEW?
Regards,
Seth

Labview error GPIB controller not adressed correctly

I get this Labview error: GPIB controller not adressed correctly (LV5.1, win NT4) when i try to send data to a HP4275A LCR meter. How ever it works on an older system running with LabView 5.0 (also NT)!!!
How can I get rid of this problem????

Hi Diego, thanks for the hints!
I tried to configure (GPIB) everything standard.
when I try a 488 command initialze, I get the controller conflict, when i don't do this I get atime out problem either by 488 write-command or by 488.2 send-command.
the differences between the systems where it works and where not are:
working: Win 95, LV 5.0, GPIB-card/TNT (plug & play)
not-working: WinNT, LV 5.1, GPIB-card/PCI
i tried to set baord config to the same parameters...
on the faulti system however I see the instrument with the MAX and I can send commands, without problems !!!!
Also the driver you posted does not work (but the NI-communicate program ;-)
i have no clue what else to do!
btw. how do I copy the spy output when running the program? I may provide
this to find errors.
Since MAX indicates the board is all right I guess it is not necessary to reinstall the boarddrivers?!

I was given a task to find out more information on the following before we purchased anything. Please, can you answer the following questions regarding the IEEE 488 to Ethernet.

1) How do we connect our network analyzers to the network?
2) What do we need to purchase?
3) How much is this going to cost us?
4) What kind of capabilities will this give us? (if any)

I think you are talking about the GPIB-ENE from NI.
1) You have to setup the ENET box by giving it an IP address. You may also need your Sys Admins help to do this. After that you will need to install the software, connect to the ethernet and connect to the equipment.
2) GPIB-ENET/100 from NI. Not sure if the NI488.2 comes with it or seperately, but you need it also.
3) Between $1,000 and $1,500 (US)
4) I like this solution. It allows you to control IEEE 488
equipment from virtually anywhere. You do not have to have a GPIB controller on every PC, but only on the equipment to control. I have test stations that I roll from place to place. I don't have to worry about connecting the station to a PC. I simply plug the station into the LAN and use any PC I want.
If you have e
quipment that you would like to control from anywhere or move from place to place this is the only way to go.

Communicate to a Fluke 8840a, VB, IEEE-488; Error ECIC(1)

I am trying to communicate to a Fluke 8840a using VB 6/Measurement Studio via IEEE-488
Using Explore GPIB I can scan and find the DMM. However when ever I try to “Communicate with Instrument” I’m getting a ECIC (1) error [NI Spy] no matter what is typed into the “send string”. I have been through the help files and nothing has worked or I am doing something wrong [most likely].
I have look at the fluke example and other examples and it is not much help as I keep getting the CIC error
I know the interface works on the DMM because it is calibrated through the port.
NI-488.2 Version is 1.6, NI Spy is 1.4. My development system is Windows 2000 [no out side net connection]
Any help is much appreciated

Matt S,
This was not the answer I was hoping for but what I sort of expected. The reason was the additional paper work I needed/had to go through to allow the download of the executable from the net.
I got the upgrade installed and was able to read the DMM through the Explorer with no problem. From here, I do not expect any further problems.
Thanks Again
Matt

Will somebody provide me with a QBASIC 4.5 PROGRAM for Interfacing with a Anritsu make(model-MS710) Rf spectrum analyser through GPIB ( NI-488.2 ) in DOS environment? I would like to aquire from the instrument and save the data in PC.the data

Will somebody provide me with a QBASIC 4.5 PROGRAM for Interfacing with an Anritsu make(model-MS710) RFspectrum analyser through GPIB ( NI-488.2 ) in DOS environment? I would like to aquire data from the instrument and save it in PC for printing purpose.

Hello,
Unfortunately I was unable to find a driver for this instrument. This leaves you with one of a couple options. First, I would like you to submit a request for this driver at:
http://www.ni.com/devzone/idnet/other.htm
We develop drivers in CVI and LabVIEW based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one. While this would not provide you with a QBASIC program, you may be able to create a DLL that you could call from QBASIC.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndica
te of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:

How to synchronize the data acquisition from both GPIB and DAQ card

I want to begin/stop acquiring the data from GPIB and PCI6024E card into Labview at the same time. Since the acquisition from GPIB is quite slow comparing to the one from DAQ card, I can not put both of them in the same loop structure. Is it possible to synchronize them?
Thank you!

Hi,
I wanted to save data acquired from NI-DAQ (for example, NI 9234) in a file using the DAQ-mx ANSI C Code. The response I got was as follows:-
One way to do it is with TDMS logging. DAQmx comes with functions designed to log to a TDMS file. This is a special file type that is used for collecting data in a logical format. It can be displayed in a TDMS viewer where data is separated into groups and channels. NI-DAQmx provides examples for how to log to TDMS. Look at the TDMS examples in the C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage directory.
However, now I want to know is there a way that using that same C code, can we save the data in a .txt file format (Text File) instead of a TDMS file? We actually want to access that file through MATLAB (that's why we want to save it in text format).
Also on an other note, is there a way we can access & open TDMS files by MATLAB?
Thanks,
Sauvik Das Gupta
