error 1073807343 ELVIS II

[samewings]

Greatings, everyone!

When I try to execute function generator or scope exaple in LabVIEW, I have this message. 

ELVIS II is identified in MAX and I can run applications in LabVIEW, that use analog inputs and outputs, but I can't use instrument drivers.

Error 1073807343 means, that I have problem with VISA.

Indeed, I don't see any of instrument descriptors in VISA Interactive Control, and I always have a message "Unable to open session to "ASRL10::INSTR"".

I've created and installed .inf file according to that topic: http://www.ni.com/white-paper/4478/en/rating/4,  but it didn't help.

Now I have no idea about, what is that. Maybe somebody can push me to think.

I got all compatible versions of instrument drivers for LabVIEW 8.6, NI DAQ Device Driver  9.5.1, NI DAQmx Base 3.2, NI VISA 4.4.1, NI ELVISmx 4.0...

Best regards, 

Anton

Sorry, that makes no sense. What instrument driver are you trying to use with the Elvis and why on earth you would do anything with creating your own USB driver for it? That page you linked should only be used when you do not have an existing driver (like you do for an Elvis) and when you have access to the very low level USB protocol (which you don't).

I did it, because i'm new in work with VISA, and didn't kmow what kind of problem I have.  I just was reading NI VISA Help and doing something. Maybe later I will grow up in this area and will not do stupid things.

But I can't understand, why in VISA Interactive Control I don't see anything.

The question is, why would you expect to see something? If you created your own USB driver, then it would be in conflict with the driver that is supposed to be used with the Elvis, even if you created the inf file correctly.

You would need to restore the system to a point before you tried to create your own. Possibly would need to reinstall the Elvis software.

The NI ELVIS II, NI ELVIS II+, and NI myDAQ only require installation of the NI ELVISmx driver (which will install DAQmx if it is not already installed).  There are no external instrument drivers that are needed.  Everything goes through DAQmx.  The easiest way to get started with the instruments is to use the express VIs installed into LabVIEW on the Measurement I/O»NI ELVISmx palette.  This will create a block for using each instrument with the settings you configure in a dialog.  If you then want to modify how the block works, you can always convert express VIs to regular subVIs and look at the code (but once you do this, you lose the ability to configure through the dialog).

However, given the current set of software you mentioned, this palette may not show up in your LabVIEW version.  LabVIEW 8.6.x support for these express VIs was not included until NI ELVISmx 4.0.1, so if you have 4.0.0, you will not see these.  The latest version of NI ELVISmx that supports LabVIEW 8.6.x is 4.3.1.  The latest version, 4.4, has dropped support for LV 8.6.x.  You'll need to make sure you have ELVISmx 4.0.1 to 4.3.1 installed to get this palette and the express VIs.

It's me again.

I've installed NI ELVISmx 4.3.1,  as you said, but now MAX can't find or recognize device. Below "Devices and Intefaces", instead of "Dev1/NI ELVIS II", I see "NI ELVIS II "USB0::0x3923::0x73A6::01395B8D::RAW"" with icon of USB device. When I try to open some instrument from ELVISmx-> Instruments, it can't find device.

It sounds like the system is addressing the device according to the driver you set up for a generic USB device.  It should be using the DAQmx device descriptor, which would just be something like Dev1.  After you create a driver like that, I'm not sure how to disable it, but you might take a look at the following links about configuring the Resource or Instrument Descriptor in MAX to see if you can get it to show up as a DAQmx device.

System Restore point as long as a restore point was made before doing the changes. Manually, the inf and pnf files can be deleted.
