• How to connect several GPIB-usb-hs instruments?

  I want to know how can I connect several instruments and acquire their signals with a GPIB-usb. I m using 2 multimeters, 1 temp. controller and 1 power supply and I have all the drivers I need. I just need to gather all the drivers 1 prog. to control via GPIB. I have 1 gpib-usb-hs, but I need to read that data from those equips. Any help and advice are welcome.

  Thanks in advance.

  No, what you're asking is done all the time. It must just be a little careful about the management of your written and reads as in most cases, you can connect to only one instrument at a time.

• I have two devices gpib-usb-hs; two of them work in MAX, but will only work in labview, help please?

  Hello

  For my application, I need to communicate with two instruments by using both devices gpib-usb-hs. I use Windows XP, Labview 6.1, MAX 5.1 version and NI488.2 version 2.42. I checked and this ni488.2 driver should be compatible with my devices gpib-usb-hs and my versions of windows and labview. I also tried versions older and more recent NI488.2 without success.

  I can communicate with my instruments properly in MAX, tell me that the devices themselves are functional. When I try to connect with my instruments using labview (using the example of gpib of labview), only devices gpib-usb-hs communicates with success. The other device returns the EDVR error: connection to the device or driver error.

  I don't really know where to go from here. The only thing I found strange was that the gpib-usb-hs work was has an alias name assigned visa while the unworking device does not. I tried to give him an alias name, but this did not help.

  Any suggestions would be greatly appreciated.

  There are many free tutorials on GPIB. It should explain how the various instruments can be connected to a single controller.

  That being said, even if it's unnecessary, you should have no problem with multiple controllers on the same pc. The two being connected, they pass all the tests in MAX? You are using an old driver and seem to have tried several different versions. I suspect a driver issue, and I advise you to uninstall all the drivers GPIB and VISA and then start again. But not all necessary can be done to satisfy your curiosity.

• Connection of an instrument with GPIB-USB connection.

  I am trying to use a GPIB-USB adapter to control a unit of Source of LabView. However, I have problems my instrument drivers to recognize the GPIB address specified for the device. I have attached an image below the address specified by IO Keysight connection Expert. I am currently trying to initialized the EMS with the GPIB driver I have attached below. Because of my knowledge limited in LabView instrument control, how should I approach of collecting the correct address of GPIB and recognize it in my VI?

  Hi wyattcurtis824,

  Before we dig into the LabVIEW code, I would recommend a Test Panel of max aperture and trying to communicate with. Are you able to send orders via Keysight connection Expert or NI MAX and see the valid data?

  In addition, when you run the vi in LabVIEW, is pilot it returns an error in the error on the box? If so, what the error is?

  This shoule information help us to the root of the problem.

• Connectivity of VISA GPIB/USB Agilent 82357 B

  Hello

  I'm under LabVIEW 8.5 on a 8106 PXI controller.  I connect to an Agilent E3632A DC Power Supply via an Agilent 82357 B GPIB/USB cable.  I installed the Agilent IO 15.5 Library Suite and have NI-VISA 4.4.1 installed as well.  All my gear of PXI chassis and NEITHER appear in MAX.

  LabVIEW is currently not able to see my 3632 on the bus A VISA, but the Agilent connection Expert he sees very well.  I am at a loss as to why NI-VISA do not.  Help, please!

  Thank you

  Sean

  Thanks for the replies, but I found it finally.  The Agilent IO 15.5 Suite library helps:

  Activation of the NI-VISA for Tulip Passport

  For software OR recognize the Agilent material, you must activate the Passport NOR VISA for Tulip. It is a software module that is included with NI-VISA for support of Agilent material and is not enabled by default. Use the NI Measurement and Automation Explorer (MAX NOR) to activate the passport for Tulip.

  In versions 3.0 and later of NEITHER MAX, you can do:

  Beginning NOR MAX
  Click Tools > NI-VISA > VISA Options...
  In the tree, select passports.
  Select the passport for the Tulip checkbox.
  Click Save to save the settings
  Output OR MAX, wait a few seconds and restart NI MAX (you must restart NI MAX for your changes to take effect).

  For details specific to your version of MAX to OR see documentation of NOR.

  It worked like a charm.

• Agilent E3640A PSU with GPIB-USB-HS

  Hello all, I created an Agilent E3640A power control software standard interface GPIB. It works very well. Now, I want to replace the standard GPIB interface (with GPIB card) with GPIB-USB-HS adapter cable, so that I can send commands via USB connection, eliminating the need for GPIB card. How can I use my existing application to work with GPIB-USB-HS adapter cable? Is this a change? or I completely rewrite the code, and if so, are the drivers available for GPIB-USB-HS adapter cable? Thanks Jeet

  More information please.

  Have you removed the PCI interface before you try the USB interface? If this is not the case, your program may still try to access the E3640A on the PCI card.

  What is the USB HS recognized in Explorer measurement and automation as GPIB0?

  The E3640A knows if scan you for Instruments to MAX?

  What (number) error is raised during the execution of your program with USB HS?

  It would also help if you could show us NI SPY logs saved when executing your program with PCI and USB-Interface Card

  Usually you don't need to install different drivers, because the package NOR-488. 2 installs drivers for all variants of the NI GPIB hardware.

• Streaming (record) data of Agilent 6674 interface GPIB-USB powered

  Hello

  I would like to save the output in more than 200 HZ to my power supply CC 6674 A Agilent with LabVIEW 8.2. Agilent 82357 A GPIB-USB interface is used to connect the power to the computer. And I used the instrument for Agilent 66XX driver I downloaded from OR.

  For reading continuous data, I put the read.vi in a while loop and data saved by writing in the file lvm. (just for the starter, not a good sense, though) Please see the attachment.

  The problem I have is that I can only save data in ~ 10 HZ then that what I need is at least 200 HZ.

  It's my first time to the instrument control and I just had a little experience in the acquisition of data before. I had some confusion as below: no I have gained a point each time the while loop is executed? If so, I guess that the time for each loop (and therefore my data rate) depends on my operating system and the computer I have.

  How many points will be acquired whenever the read.vi is run? That depends on the set 'count bytes' in vi or a single point anything? Are there other ways to get the data more efficiently? (want to write your own driver etc...) Any help would be much appreciated.

  See you soon,.

  Bohan

  The rate at which you can run the VI is dependent on the instrument/GPIB bus and use of Scripture on a Measurment file. Yes, you get a voltage reading and a current reading with each iteration and the number of bytes read is so that you can get a complete reading.

  I suggest you delete the entry in the file of the measurement of the loop to see how long takes of the instrument. That would be your maximum rate. If it's fast enough, use a different method to save the data. Architecture of producer/consumer if you pass the data to another loop via a queue would be a way.

• GPIB-USB-HS will recognize any instrument in LabVIEW but somewhat done in MAX - help

  Hello

  I'm having a problem getting my GPIB-USB-HS device to recognize instruments in LabVIEW.  The unit has been running year last on many instruments.  I tried the GPIB-USB-HS other materials too just to make sure it wasn't a defective unit.

  NOTE: I installed the latest drivers for NI-VISA 5.1.1 and 300 of NOR-488. 2 for Windows XP

  See the images below:

  It's the idsplay to the MAX:
  I'm not sure why there is a yellow "!" next to GPIB0::INTFC, I think it's an indication of my question.  However, note that the instruments connected to my GPIB-USB-HS are counted in MAX.  As you'll see LabVIEW 8.5 does not recognize them.

  

  I get this error Max warning when I try to open TOOLS > NI-VISA > VISA INTERACTIVE CONTROL:

  

  It comes to the image of my LabVIEW 8.5 window when I try to select a VISA of an instrument (including MAX recognizes):

  

  Any help would be much appreciated

  Thank you all for your help,

  Problem solved after hours of uninstallation and reinstallation of all devices/software from National Instruments.

  Once all programs have been uninstalled (with a disk cleanup on my unnecessary hard-maybe records)

  LabVIEW 8.5.1 has been reinstalled

  NOR-DAQ has been reinstalled

  NI-Visa 5.1.1 has been reinstalled

  NOR-488. 2 worm 2.7.3 has been re-installed (correctly)

  Now, LabVIEW recognizes all ports/devices and connects to the instruments properly once more.

  My question must have been installing LabVIEW 8.5.1 after already installing LabVIEW 2009.

  Somewhere during the installation of 8.5.1 - main post problem occurred.

  Thanks again

• Can I use a USB hub to connect to more of a GPIB-USB-HS USB ports?

  I have an instrument that has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple computers to connect with USB hub in their respective USB ports? If so, how many computers can I connect using the USB cable?

  I downloaded the latest Driver NI-VISA from the Web site.

  You must first a hub which allows to switch between multiple PCs and PCs as one would at once be connected and in control.

  When you buy this particular type of hub, one of the specifications is how many pc connections there.

• MAX does not detect my instrument 488.2 GPIB-USB-HS, but Windows XP Device Manager only

  Hello

  I have a problem when you use the 488.2 GPIB-USB-HS, I see the device in Windows XP Device Manager, but it is not visible in the MAX, I do not see even a section for devices GPIB. However, when I try to install a new device, GPIB, the Wizard MAX tells me that it is one of the instruments GPIB installed on the computer which GPIB0 - USB-GPIB-HS. Do you know what is the reason to do this, because I want to use a multimeter in LabVIEW via GPIB, but I can't access it, I don't even see that there is a GPIB connection in the computer (in LabVIEW).

  Kind regards

  It's the kind of old. Have you tried the last?

• Agilent 82357 B GPIB/USB, problem with distributed applications

  Hello everyone,

  I am developing software that communicates with an instrument, with USB, RS232, Ethernet and GPIB interface

  On my development PC, I can communicate with my instrument using a 82357 B Agilent GPIB - USB converter, without any problem. (and other interfaces as weel)

  I have deployed the application using the Installer application on the target computer Builder. The application works with USB, RS232 and Ethernet interfaces, but I don't see the GPIB interface in the control of VISA resource name.

  I followed the advice given by OR when you use a converter USB GPIB of Agilent (Tulip active...)

  I did the following tests on the target computer:

  -J' installed MAX, and I can communicate with the VISA test panel using the GPIB-USB converter.

  -J' made a small application with the VISA resource find included

  -If I unplugged the converter USB/GPIB instrument, the VISA to find the function return resource: GPIB0::INTFC, COM3, COM4, LPT1 COM7

  -If I plug the converter to the instrument, the function of resource VISA finds return nothing.

  -If I run the interactive command of VISA, I got the following error:

  Cannot find the resource by using expression? " »

  error: BFFF003A

  Name of the State VI_ERROR_INV_SETUP

  I'm using LabView 8.5 under windows XP.

  I have included in the installer

  -Run LabView 8.5

  -VISA 4.4 duration

  The target computer is running Vista.

  Thanks for your help and your support.

  Hello everyone,

  For your information, I have solved the problem in desinstalling then reinstalling my installation software on the target computer.

  I still don't know where the problem was, but it's working now. (even with the version of the driver 15.0 agilent)

  Thanks anyway for your help.

• GPIB instrument legacy Microlink 4000 using GPIB-USB-HS

  Hi all

  I face three recorders of older data, Microlink 4000, connected through GPIB and interfacing with my PC through GPIB-USB-HS.

  There is no drivers for data loggers...

  Their main in MAX addresses are displayed and I am able to send commands, but I'm not sure what to do now to begin to read the data recorded by each module.

  I think that I am just not access to the secondary address of each module or using the wrong commands. I've scoured the web for the manuals and orders 488,1 but they do not work in the interactive control of VISA.

  that is (Hex 0xBFFF0015) Read error occurs whenever I ask devices...

  Specification of the system:

  • power supply 3 x 4301
  • control units 3 x 4300
  • basic unit of time 1 x 4010
  • 34 x 4030 (12 Bit A - D converters)

  I apologize if I have not attached enough information still very new to LabVIEW and MAX.

  Please advise!

  Thank you very much

• Problem of earthing GPIB-USB-HS connecting to a laptop?

  Hello

  The installation guide for the GPIB-USB-HS asks to "ensure that the computer and the GPIB devices are at the same potential on the ground."  I was wondering if there could be problems with the connection of portable computers (because they float)?

  What should / could happen if the computer was at a different potential on the ground?  A short circuit?

  Where the potential of the Earth is different, the installation guide also mentions to use isolated a GPIB bus isolator/Expander or a USB hub.  I guess that laptop USB ports are "isolated" and so should be good.  Is this true?

  Thank you!

  Meister,

  Because your laptop is "floating" it's referance (mass to the chassis) has nothing to do with your referance of material (Earth) unless you take measures to link the laptop chassis to earth potential.  Attach a GPIB cable to your laptop and your equipment will provide a way to fulfil the potential difference between your laptop and chassis of the Earth through the GND signal on the Gbspecifications FOR bus.  The GPIB bus is not intended to carry large currents (great potential of discharge) and you can force entry on the laptop protection circuits or equipment when you connect the GPIB cable.  Its kind of like touching a doorknob one day dry after you walk on the carpet of wool - you will get a 'static' shock when make you initial contact.  Do it at your equipment and laptop often enough and you will damage them.

  A worst case is when the chassis of the laptop is linked to a different potential that the grounded equipment (usually due to strengthening of wiring errors).  In this case there must be a current constant circulating in the commonly known GBIP GND signal ground loop.  Noise and / or damage will be celebrated according to potintial unlike.

  The cure is ALWAYS connect the chassis of the laptop on the chassis of the equipment by an external wire before connecting the GPIB Bus.

  I hope that clarifies the reasoning of 'Warning' that you see in the installation guide.  Kudos to you for reading your guide and to pay attention to the warnings!  Never be afraid to ask when you don't understand warnings

• Interface and installation of my instrument with lab view and keithely, GPIB-USB-HS

  Hai...

  We have 236 Keithleu and software vision lab and GPIB-USB-HS. I had the GPIB software installed is OR-488. 2 3.1.1

  Now, I had the indication like that.

  1. in Kethely no indication

  2. in GPIB +'s got orange led in ready icon.

  3 but if I runt the program I found no results.

  So can you me the interfacing of the keithlye and alo for the GPIB and also computer.

  The pilot here can help you. I suggest you first learn how to set up the action manually. Then study the programming guide to understand what commands you need and the settings for them. Good luck.

• GPIB-USB-HS and USB-8451 communication issues - appearing only in VISA

  Hello

  I recently started a new job and have had communication problems between my adapter GPIB-USB-HS, my VISA or MAX-Labview and USB-8451 I2C/SPI interface.  I installed LabView to 32 bits, OR-488. 2, the driver for the 8451 on my windows desktop and VISA 16.0 7.

  In the windows Device Manager, the 8451 appears as a device USB of NI-VISA and Gbspecifications FOR-USB-HS presents itself as a GPIB Interface of NOR.  Two of these instruments are recognized NI Max so but communication Gbspecifications FOR add-in adapter (and connected instruments) fails and he can't find the instruments and the self-test fails with a hardware error unknown gpib (-37052).  The watch also neither device VISA Interactive Control.

  The ready light is lit on the GPIB-USB adapter and the 8451 flashes green as if nothing is wrong at the end.  I uninstalled all the software of NOR and reinstalled, and I run MAX as an administrator.  Is there possibly some computer settings I could neglect or need to change to open a communication?  Any other ideas on why I can't communicate with devices?

  Thank you!

  Trey

  This is a device-Lock software that my it was preinstalled on the computer blocks the USB port.  SHE has added features like confidence, and now it works.
