MAX can't see my Agilent 82357A GPIB/USB converter
I have a LV 8.5 program that talks to an Agilent 34970A through the subject converter and generally works well except I often lose comm. Also when I first start my LV program it can't establish comm until I run the Agilent Connection Wizard, then LV and MAX comm ok with it. I've tried a different converter with same results. I'm using the Agilent Initialize vi, which is where the error occurs. The error I get is "Error 1073870264 occurred at VISA Clear in HP34970A Initialize.vi.....(Hex 0xBFFF00600) The interface associated with this session is not currently the controller in ...MAX can't find Agilent 82357A GPIB/USB converter
I'm having intermittent problems communicating with my Agilent 34970a through the Agilent GPIB/USB converter. My Labview 8.5 program uses the Agilent Initialize vi, and cannot recognize the GPIB/USB converter unless I first run the Agilent communication wizard, which successfully communicates with it,then my LV program and/or MAX can see it. Sometimes while debugging my LV program I lose comm, then have to run Agilent wizard, or unplug/replug the USB cable to re-establish comm. I've been on the phone with Agilent tech help who, after trying a lot of things, suggests I update my Agiletn...CORRECTION : Can't connect to Xserver SHOULD BE Can't connect to XVNCserver
I've got a RH 9 machine running, with x/kde.
From 2 different Windows machines (Win2k and Win98), I can't seem to
connect to the vncserver on the RH system. (failed to connect to
server is displayed, when I connect from the client)
After looking at the System Service Configuration tool in KDE, the
Status for vncserver shows "Xvnc is stopped". When I restart the vnc
service, "VNC server start was successful is displayed in a message
box, yet the staus still shows "Xvnc is stopped"
What am I doing wrong ?

I can't get LabView 7.1 to read data from the serial port. If I use the original examples, the examples given hier, VISA or not, I just get the error -1073807202 straight after the Configure vi.
Is it possible that LabView just can't communicate with Serial<->USB adapters?
The configuration should be correct: Everything is default, except for the baud rate. It is 38400 bps. Also, I *can* read characters via Win32 CreateFile() and friends. It also works with Hyperterminal. I use WinXP Pro if that matters. And yes, I use the c...Why can't I communicate with both of my GPIB devices?
I have 1 NI PCI GPIB board in my computer
I have 2 identical devices (keithley 237) connected one at address 15
one at address 16
and 2 different programs one program to connect with 15 and 1 to
connect with 16
after I tell the 1st labview program to communicate with 15 then I
tell the 2nd labview program to communicate with 16. then both
communications come back with error device timeout. one at a time, I
can communicate find with either device.
Why can't I communicate with two different GPIB devices at the same

My company has a new walkie talkie system called TETRA. Nokia THR850
is the TETRA handset model we are using. According to the user manual
of the handset, it can be used as a modem. Please click the link below
for some information of the handset.
If LabView could control my remote GPIB instruments with this handset,
I would be able to acquire data from anywhere to my office, which
would save me a lot of effort. Please let me know if this is possible?
If yes, what is the simplest way? I am a mechanical engineer with

...Why can't I run my VI.exe stand-alone when I can run it from LabView
I made a pretty simple VI in LabView (7.1 on WindowsXP) that uses the NI USB-6009 multifunction I/O device to display 4 AI channels to read voltage (simulate a 4X digital multimeter).
The VI works fine from LabView, but when I built the stand-alone application with the Tools menu feature, it won't run. I get the following error:
VISA: (BFFF000E) Given session or object reference is invalid.
Any idea what would cause this? Under Support Files, I only select the single VI (which is included in an .llb file). Should I be including a...can't connect RT target in LabView project
I use LabView Real Time 8.5 on a Desktop PC. I see the target in MAX in

Thanks in advance
Thanks for posting on the National Instruments forum.
Have you checked if all the software...LabVIEW 7 can't open source code based on LAbVIEW 6.1.
LabVIEW 7 can't open source code based on the LAbVIEW 6.1 with an
error that some VI doesn't have block diagram and can't be converted.
What to do in this situation.
You are stuck, unless you can get the source code for the VI with the
missing diagram. However, you can still open the rest of the
application. Delete the "bad" VI and replace it will new code,
assuming that you know how it works.
Jim is right.
There is no way of converting/upgrading a VI to the newer version of
LabVIEW without its block diagram. Below are a couple of KBs that
discuss this issue:

I'm trying to use a Prologix USB GPIB controller to control GPIB
instruments, and I would like to have a virtual serial (VISA) port for
*each instrument*, as is the case with a normal GPIB controller with a
standard NI driver. However this is not what the Prologix driver
provides -- it provides a single VISA virtual serial port for the
entire controller. To address the instrument with GPIB address 11,
you first send "++addr 11" to the serial port, and then you're talking
to instrument 11. However, this means I have to change all old
