Programme pour piloter un appareil via adaptateur GPIB-USB

Bonjour,
Nous possédons un appareil HP70004A (avec port GPBI) dans
lequel et intégré un second appareil HP70340A.
Mon problème est le suivant : j’aimerai pouvoir
commander ces appareils via LabView avec un connecteur GPIB-USB mais je n’ai
pas trouver (sur votre site et autre) le programme permettant de le faire.
En revanche je possède un programme en « .id » qui lui n’est pas
compatible avec LabView.
Existe-t-il un moyen pour convertir un fichier « .id » en fichier «.vi » ?
Si oui le quel et comment faire.
Ou alors possédez vous directement les programmes de LabView pour piloter ces
appareils ?
Cordialement.

Bonjour,
Pour ta question, je ne sais pas si cela est possible. Je suis dans le même cas que toi. Je suis en stage et j'ai du commander un multimétre HP34401A via un convertisseur GPIB-USB, qui est pour moi un GPIB-USB-HS de NI (qu'elle est le tien?)
Pour commander ton appareil commence par regarger sur internet si tu ne trouve pas des VI déja crée pour le mettre en oeuvre, si tu ne trouve pas il suffit de regarder dans le doc de tes appareils et de regarder les commande qui lui sont propre.
A-tu déja réalisé un programme simple juste pour réaliser un RESET ou une identification pour commancer ou utiliser Measurement et Automation?
Cordialement.

Peut-on utiliser le deuxième port TCP/IP de mon NI cRIO pour piloter un appareil de mesure Agilent

Bonjour,
J'aimerai utiliser le deuxième port TCP/IP de mon NI cRIO-9024 pour piloter mon générateur de pulses Agilent 33210A.
Est-ce possible?
Mon appariel ne possède pas de port RS232, mais seulement du TCP/IP et GPIB.
Cordialement.

Bonjour,
Merci pour votre réponse.
Je voudrai untiliser le VISA TCP/IP.
Comme c'est un apareil Agilent il faut activer le passport NIVisaTulip.dll et
celui-ci n'existe pas sous NI-RIO, il a y des passports nom.out.(Cf pièce jointe1).
De toute façon dans un premier temps je n'arrive pas à ajouter un nouveau périférique réseau
à partir de mon NI cRIO (Creat New VISA TCP/IP Resource).
J'ai activer mon deuxième port avec une adresse IP qui correspond bien avec mon appareil.(Cf pièce jointe3)
Il faut bien procéder comme cela ? (Cf pièce jointe2).
Cordialement,

GPIB-USB-B 4882query.c erreur de compilation

Bonjour,
J'utilise un adaptateur GPIB-USB-B. Celui ci communique bien avec mon instrument (optical multimeter) lorque j'utilise MAX.
Maintenant, je cherche à piloter mon instrument directement en langage c c++. J'ai trouvé un example nommé 4882query.c, mais à la compilation sous VS 2008, je suis confronté à un problème de linker :
------ Début de la génération : Projet : test, Configuration : Release Win32 ------
Édition des liens en cours...

J'ai ajouté le fichier gpib-32.obj dans les ressources du projet et ni4882.h dans les header. J'ai consulté des posts sur le forum NI, mais rien ne m'a permi de résoudre le problème.
J'ai déjà passé du temps à chercher, donc si quelqu'un aurait une idée, ce serait super !
Merci d'avance.
Paul

Bonjour Paul29o,
Une petite question: avez-vous bien pensé à ajouter le fichier ni4882.obj dans le resource file de votre projet? Vous ne le mentionnez pas dans votre message, donc je voudrais m'en assurer.
Merci

Can't see boards in a VXI chassis connected via VXI-MXI-2 cards using a GPIB-USB adapter

I'm working on a system that has two VXI enclosures, and the two are bridged via VXI-MXI-2 boards in each of them. The first one has a GPIB-VXI board in slot 0, and I have a Winodows XP computer connected to that with a GPIB-USB-HS adapter. The problem is that I cannot see any of the boards in the second chassis over GPIB in the Measurement & Automation Explorer. As far as I can tell, everything is configured correctly; the VXI-MXI-2 board in the first chassis is in the last slot and has a logical address of 126, and the VXI-MXI-2 board in the second chassis is in slot 0 and has a logical address of 127. To make things even more confusing, if I put a VXI PC in slot 0 of the first chassis, it seems to see everything without any problems. Do you have any idea why this might be happening? I'm pretty new to working with these systems, so I might be missing something obvious. Thanks in advance.

Nevermind that -- I just discovered that you can't bridge two VXI chassis with VXI-MXI-2 boards if you're using a GPIB-VXI board as the controller. So, I'll just have to find another way to accomplish what I need to do.

HT4101 When connecting my camera to my IPad mini via lightniing to usb camera adapter,I get "The attached accessory uses too much power" .Any solutions?

When I connect my Ipad mini to my camera via lightning to usb camera adapter all i get is a message "The attached accessory uses too much power."Any solutions

It depends on the camera, but some have a special mode for offloading photos but not trying to charge the camera through the USB port. For others, you may have to pull out the SD card (if that's what it uses) and use the Lightning to SD card reader instead.
Maybe if you told us what camera you are connecting, somebody here with the same model can give you more specific information.

I want to connect a usb drive via adapter cable to my nokia C2-01.is this phone support usb otg feature as in nokia x2-00?if not then please recomend a method to connect a usb drive to this phone..
Solved!
Go to Solution.

Hi mate,
Sadly the Nokia C2-01 does not support USB OTG functionality. There is no method AT ALL to connect a USB device to this phone in the way that you have stated. If you require storage then instead of a USB drive you can use a microSD card up to 32GB, as the phone supports it.

Can thunderbolt display connect to Win7 pc via adapter?

Needing a second large monitor compatible with my two systems: Macbook Pro w Bootcamp Win7 64-bit and HP Win7 64-bit workstation. Can this display connect to my PC workstation via adapter? Can it mirror an existing flat screen? The existing flatscreen monitor mirrors the Macbook Pro just fine, except for resolution differences.

Your Win PC would need a Thunderbolt port. If it does not there is no adapter that will make it work.

Compatibility of Agilent GPIB/USB adapter with NI

Hi,
I have an Agilent GPIB / USB adapter 82357B, and I'm experiencing some problems for detecting my instruments in the laboratory when I try to use the labview software for capturing the data from the measurement instruments.
I installed the CD with the libraries the adapter has and through this software I can detect the instruments, however once that I open the Labview software from National instruments(NI) for capturing my data, I miss comunication with the devices in both programs, the Agilent one and in the MAX of NI.
I run across a document regarding tip on using Agilent GPIB solutions in National instruments's Labview environment. I have done all the document indicates, but It is not workingt, I experience the problem I outlined above for detecting the instruments.
I hope someone can help me with that.
Regards

Yes I am. According to documents it is possible. But I don't know want else to do, since I have done what document indicated. I as mentioned in previous message, now I can see the measurement instrument with Labview and using the Agilent cable adapter, and I can stablish communication with device since that when I select the device in the labview program, a led in the instrument is ON, indicating communication. However when I try to capture the data on screen, there is not data at all.
Hello DCU STUDENT,
It sounds like there may be some conflict between the NI VISA and Agilent drivers, which can occur between certain models; considering when you use the NI cable data can be collected when when you're using the Agilent you cannot. Please tell me what versions of both drivers you are using so I can determine whether or not there are any known incompatibilities between the two if you're still receiving the same error after following these instructions.
Can you also please go through this instrument troubleshooting guide to see if your installation matches the expected configuration of a functional device so we can confirm that your driver has been installed correctly from the previous guides.
For a IEEE488 Agilent Device Card, as you mentioned that you have the NIVISATulip.dll enabled, for this GPIB configuration to work you must ensure that the 488 Programs must be activated with NI 488.2 (At the Enable Agilent GPIB cards option) through the Agilent Connection Expert.
You've mentioned that you've been able to establish a connection with the device and see communication transfer, yet you are getting no returned communication. Do you see a similar response when you view the device through the Measurement and Automation Explorer?
If it is possible, could you test your configuration with any other Agilent devices with your current configuration and see if the error persists?

Je viens d.installer Time capsule airport , il fonctionne correctement pour les sauvegardes mais la connexion ethernet pour les autres appareils ne se fait pas pourtant j.ai bien branché un câble ethernet entre airport et ma box ?

Je viens d.installer Time capsule airport , la connexion pour internet se fait correctement
J.ai bien créé un réseau pour mes autres appareils mais la connexion ethernet ne se fait pas, l.ordinatueur indique que le câble n.est pas branche, alors que j.ai bien installé un câble tout neuf entre airport et ma box Sfr
Donc je peux sauvegarder mon Mac et c.est tout je ne peux relier mon iPad et mon iPhone à airport
Que faut il faire ?

Ok, i finally succeeded
Now the TC is linked by WiFi, but as you said, now, it's just an external device, impossible to join it :/
And it's not what i want because i need to access to it outside
If i'm right now, i say thank you, you really helped me even if it's not what i want exactly.
So Ethernet :/
Thx
---------------------------------------------- Translation
Pour les français, en gros, je dois utilisé le logiciel AirPort Utility version 5.6 (mais il me semble que le 6.0 le fait aussi en faite, j'ai pas trop regardé du coup) pour pouvoir non pas créer un nouveau réseau sans fil mais en rejoindre un
Grace à cela, la TC se connecte à la box sans fil mais devient un appareil externe, ce qui veut dire qu'on ne peux pas se connecter dessus en sans fil ou même y accéder de l'extérieur (comme moi)
Juste y accéder comme une clé USB et accéder au donnée, rien de plus.

Does anyone know yet if the new iPad will support a USB microphone plugged into Garageband via iPad's USB Camera Adapter?

Hi,
I've ordered a new iPad 64Gb which will arrive early April. My hobby is making music, so does anyone know yet if the new iPad (3rd generation) will support a USB microphone plugged into Garageband via iPad's USB Camera Adapter? I am hoping to use such a portable setup to record live performances of voice & acoustic instrument.
Thank you,
John.

When in doubt, try it out. I bought the Apple camera connection kit & used it to connect my Blue Snowball usb mic to my new iPad 3rd generation. It works just fine. I made some test recordings in GarageBand on my iPad 3 using my Snowball mic. They sound great.

Emulation d'un port com via un port USB en LabView

Bonjour,
Dans le cadre d'un projet, un FPGA (vertex V6) m'envoie des trames de données à interpréter dans LabView. Le soucis qui se pose est le suivant, voulant traiter les données dans LabView, comment est-ce que je peux paramétrer le NI-VISA pour recevoir les trames ?
Le soucis réside dans le fait que mon matériel FPGA n'a pas d'identifiant propre et que je n'arrive pas à le configurer proprement . Doit-je passer par un adaptateur USB-Série ou bien existe-t'il une solution purement logicielle ?
Merci d'avance.
Résolu !
Accéder à la solution.

Bonjour Sylvain_j05,
Le driver VISA propose un jeu de fonctions haut niveau qui permettent d'appeler des fonctions bas niveaux. Si vous utilisez un port USB en partant de votre PC, vous devrez avoir également un port USB disponible sur votre matériel contenant le FPGA et permettant de récupérer ses valeurs. Sinon, un adaptateur Série-USB peut être envisagé s'il n'y a qu'un port série disponible sur votre matériel.
Vous pouvez également essayer un adaptateur USB-Série sur votre PC (si ce dernier ne dispose pas de port série directement intégré) qui vous permettra d'avoir des ports série directement disponibles depuis votre programme sous LabVIEW.
Exemple d'adaptateurs existants : NI USB-232, NI USB-232/2, NI USB-232/4
N'hésitez pas à fournir davantage d'informations et notamment à répondre aux questions d'Helmut O'Brian.
Cordialement,

AT300se...can I connect to TV via the micro USB port?

Hi, I was wondering if I can connect to my TV using the micro USB port on the AT300SE model tablet. This version does not ahve the micro HMDi port so i was wondering if I could use an adapter to conenct to my TV via the micro USB? Thanks, Nikos
Solved!
Go to Solution.

Looking at the specs, this tablet does not have HDMI. So I see no way you can connect it to your TV. Some of the newer TV's may be able so share your network to play files that are on your tablet.

Is GPIB-USB-B compatible GPIB card? if yes, which card and driver?

I have my codes written while I was using GPIB-USB-B to communicate with HP-4145 from my PC win-XP.
Now I want to use a GPIB card rather than the USB version.
1- Can I use a GPIB card without changing my codes?
2- if yes, then which GPIB card( and which driver) should I use?
Thanks
Solved!
Go to Solution.

does any one know the proper location to use firmware upgrade for GPIB-USB-B
$ rpm -q kernel
kernel-2.6.18-274.7.1.el5
------ result from exe command line ---
[root@gb095 ni_gpib_usb_b]# fxload -D /proc/bus/usb/003/001 -I niusbb_firmware.hex -s niusbb_loader.hex
can't modify CPUCS: Broken pipe
README FILE CONTENTS
The firmware files can be uploaded to your NI GPIB-USB-B adapter
using fxload. Example:
fxload -D /proc/bus/usb/001/002 -I niusbb_firmware.hex -s niusbb_loader.hex
If you wish for the firmware to be automatically loaded through hotplug,
copy the firmware files to the /usr/share/usb/ni_usb_gpib/ directory
(or wherever the /etc/hotplug/usb/ni_usb_gpib script expects to find them).
Thanks go to Michael Ritzert for figuring out how to extract the firmware
from a usb sniff log. The log that was used is included
(file name is "ni-usb-b-initialization-log.txt"), as well as the perl
script for creating the hex file ("firmware_extract.pl").
what i have to do is upgrade these cards to latest firmware to see if the work with this level kernel
$ rpm -q kernel

Nokia N78 fails to connect to PC via CA-101 USB ca...

Hi everybody.....
Please let me tell the story from the begining..Recently I purchased a China made N78 phone
with firmware ver. 12.046 / custom ver. 12.046.051.1 .When I tried to connect it to
PC via CA-101 USB cable & Nokia PC Suite ver. 6.9 (both are contained in the retail box)
it failed to connect.Although the phone does recognise the connection as a connection
icon appears on the left upper corner of the phone screen and the phone asks me to set
the connection profile e.g. PC Suite to use , while the PC tells me that a problem occured
during installation of a new hardware (the phone) and it cannot be used properly hence no
connection occures. First I factory resetted the phone , then did hardware format by
keys: (* + 3 + m.media key + power on ),then updated the Nokia PC Suite programme to
ver. 7.1 and I updated cable drivers from Nokia website and reinstalled them ,then I
updated the phone fimware using phone device manager to ver. 21.002 / custom ver. 21.002.051.1
and lastly reinstalled the Win.XP on my PC BUT THE PROBLEM IS SAME AND NO CONNCTION in every single step done respectively.On the other side the Bluetooth connection with the PC and Nokia PC Suite
works very fine. I think I checked and fixed every possible issue I could ,and the phone package is brand new and made under the authority of Nokia corp. hence its genuine one and purchased from a registered Nokia distributor in Middle East.So why this problem happens ?! I DONT KNOW , SO PLEASE HELP..HELP...

Did You install PC suite to your computer before connecting? Which mode are you using to connec PC Suite or data transfer? Data transfer shouldn't require drivers but you can get the cable driver just in case. It should be on the disk that came in the box with your phone. If you have installed PC suite make sure it's running when you plug the phone in
Show your appreciation. Hit that kudos button real hard
