I have purchased a GPIB USB HS+ and have installed MAX V14. The thing is when I look under drive manager the GPIB USB HS+ and GPIB USB HS+ anyliser has a yellow exclamation marks next to them. MAX finds it but under devices and interface it has Windows does not have a driver associated with your device. so I'm guessing i need to download the driver but when i click the link it take me to MAX V14 which i have already installed. Can anyone help.
Thanks
hai,
i am razi, research scholar, pondicherry university. i have a keithley 238 source-measure unit and 2182 nano voltmeter. i want to keep 238 as a current souce and 2182 as a voltage measurement system for my samples. may i know how to make a labview program to connect both for the i-v measuremets for the same time.....
thanks for advance
Hi,
I am currently having trouble loading Cal-kit/sequence files from my computer to my 8722ES Network Analyzer. I was wondering if anyone has experience doing something like this and could give some advice.
Thanks,

Hi,
I've recently acquired a Scanivalve DSA 3217 / 16 Px system. I am trying to set this up with my PC and has directly connected the Scanivalve to the PC using a cross over ethernet cable. I am using the given softwave, which is the NI Labview as well as the DSA Labview 2009 Utility. However, I am unable to communicate to the Scanivalve using the TCP/IP address.
Help is much appreciated as I am running a project on this.
Thank you all!

I am running 64-bit LV2014 on Mac OsX (10.9.5) with VISA 5.4.0. The "VISA find Resources.vi" returns a blank array and error -1073807343 in 64bit Labview. In 32-bit Labview, I see my three devices. Anyone running similar setup -successfully?
Thanks,
Kevin
Hi,

Thanks in Advance!!!!
Hello!
I'm using the NI I/O Trace on a PC-System.
The idea is to let it start together with windwos (autostart) for all users.
The problem is that the settings I make with useraccount "x" will not be set for useraccount "y".
Is there a solution that makes settings for all users effective?
Hi,
I am trying to write a simple piece of code in C langage under windows7 64bit to test VISA on a 64bit platform.
---CODE---
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "visa.h"
/* Variables */
static char instrDescriptor[VI_FIND_BUFLEN];
static ViUInt32 numInstrs;
static ViFindList findList;
static ViSession defaultRM, instr;
static ViStatus status;
int main(void)
{
/* First we will need to open the default resource manager. */
status = viOpenDefaultRM (&defaultRM);
status = VI_SUCCESS-1;
if (status < VI_SUCCESS)
{
printf("Could not open a session to the VISA Resource Manager!\n");
}
return 0;
}
---END OF CODE---
I am able to compile this piece of code using the visa64.lib and a MinGW GCC compiler under windows.
My problem is that when I start the generated executale file, windows opens a window "test.exe has stopped working".
If I just comment the line where the VISA lib is accessed, the executable file works coorectly.
Someone has an idea to help me ?
regards
Hello,
I'm trying to implement ni4882.dll in my Visual Basic application (using Visual Studio Express 2013).
I've downloaded NI4882_140.exe to get some examples but I'm not sure the files are the right ones.
In the readMe file of the code examples, it is said to add to the project the following files :
- NIGLOBAL.BAS
- VBIB-32.BAS
but in VBIB-32.BAS, I can see references to Gpib-32.dll whereas I would like to use ni4882.dll to have an application running on 64-bit and I have errors when compiling the project (statement expected for the first line of niglobal.bas.....)
Could you please tell me how I can use ni4882.dll functions instead of Gpib-32.dll functions ?
Is there an update of NIGLOBAL.BAS and VBIB-32.BAS I should rather use ?
Thank you.
There are two type of Instrument Drivers for the same instrument, i.e. IVI Driver and VXI PnP Driver. I want to know what is really the difference between these two and on what conditions which one is better than other?
Thanks in Advance
I am trying to simulate a SR830 Lock-in amplifier input for my VI. I am unsure what series DAQ device to select. I am somewhat new to LabView and this is my first simulated device. Guidance is appreciated.
We recently installed a new NI Slot 0 controller. We have external GPIB devices connected to it. (i.e. not VXI GPIB cards.) In our old system, everything worked together properly. In this new system, although MAX sees the GPIB devices, when running our program, the GPIB devices are NOT recognized - expect when NI-Trace is running. We tried running NI-Trace to see what is going on, but everything works when NI-Trace is running. When NI-Trace is stopped, the GPIB devices are no longer recognized. But when NI-Trace is started again, the GPIB devices are recognized, and everything runs properly. Has anyone seen this before? Does anyone have any suggestions as to what or why this is working (not working) this way? We tried re-installing the drivers, reinstalling the NI Software (including Trace) and moving things around (like changing GPIB addresses, etc.) and still no resolution.
We have an issue whereas GPIB devices won't run unless NI-Trace is running. So we have NI-Trace in our start-up so it runs when we start our test station. But this big Trace Window is disruptive to users, until they minimize the window. Is there any way to have NI-Trace start up running, but also start with the window minimized? (Yes I know there's the check box to have the Trace start upon running NI-Trace, but we'd like the window to be running in the background - (minimized) so as to allow our Test window to not be in conflict with the Trace window.)
how interfacing is done using labview ?
and how xy stage og stepper motor can be controlled using labview???
Hi,
I am controlling two output channels of E3631A power supply. The voltage and current are defined in csv file and then the labVIEW will read from the file and control the E3631A. However, after some time the labView will always crash and then display the error shown below. Does anyone know what the error means and perhaps the solution?
Thank you in advance.
How xy stage can be interfaced using labview software?
I'm running LabView 2012 on Linux (kernel 3.10) on an x86_64 machine. I think that VISA is not playing nicely with my 64-bit serial driver. I have a few instuments connected through an NPort serial to ethernet converter. Instruments which output data constantly (unpolled) are working fine. I'm reading ASCII data from those using both minicom and LabView / VISA with no problem. Instruments which need to be polled for data are not working.
The same software and drivers are working fine on a 32-bit machine in the same lab (although I compiled the NPort serial driver for 32-bit on that machine). All I can think is that 32-bit VISA doesn't like the "bitness" of the 64 bit serial driver, and it's mashing anything I try to write to a serial port. This being the case:
1) Can I install 64-bit VISA for Linux in conjunction with 32-bit Labview? Would that work?
2) If I have to go for a 64-bit LabView, do I really need to downgrade my kernel to 2.x as suggested in a hidden NI compatibility document that I now can't find?
3) Why is Linux such an after-thought with NI?
I have a teststand sequence that uses several GPIB instruments.
Using the 'Open VISA Session Monitor.vi' I can see that, when it hits the initialize for the first instrument, a session for each instrument is started.
Except one instrument starts 2 sessions.
This runs fine the first time the sequence is run after a reboot of the PC and 'Open VISA Session Monitor.vi' shows all sessions have ended. But, the second time, again sessions are created for all instruments with two for that particular instrument.
Later in the second run, several calls to the instrument with 2 sessions work, but a later call fails, complaining that a required input to the vi can't be empty. (Remember this call worked fine first run.)
Is Teststand supposed to create sessions for all GPIB instruments automatically on first access of any VISA device?
Why is it creating 2 sessions for just one device?

Mac
Hi!
I'm trying to control TCP socket status by timeouts.
TCP is linking Windows server and cRIO controller both with LabVIEW applications.
As I don't know any facts about application status in my cRIO I decide to get information about physical level of connection by writing timeout and about application level - by reading timeout (if I can't send something - ethernet is not linked or socket is dead; if I did sent packet and get timeout on answer reading only - my application on cRIO is dead).
But when I disconnecting ethernet - I'm not getting writing timeout error independently of timeout value, I'm not getting any errors on writing at all; I'm getting reading timeouts only (because my system isn't getting any packets to answer) and then, after much time, error 66 on writing (I think - when my cRIO disconnecting TCP on its side and became listening TCP device by its own timeouts).
Why it's happening?
Is there any other tools to get socket status (at least on its physical level only)?
WBR,
Igor
