Handshaking Scanning with PCI DMM and SCXI

Hi,
I am trying to implement handshaking scanning with hardware that I have. Here's my setup:
My software : NI-DMM 2.5, NI-SWITCH 3.0.49161, NI-DAQmx 8.0.0f0, NI-VISA 3.4, VC++ 2005 Express.
My hardware : PCI 4070, SCXI1000, 2 SCXI1127, SH9MD-AUX cable and SCXI 1359 kit.
First I am trying to run the example called niSwitchDMMSwitchHandshaking.c. I am getting an error message that says:
"Sample trigger or trigger source cannot be set to external when the device is configured for SCXI control"
My setup uses PCI-4070 as a chassis communicator, but this is not something that I can change. How can I solve this?
Another related question is do I need to make any additional electrical connections? One of the functions sets trigger attributes to FRONT_CONNECTOR but the "Scanning Switch Modules" document explains that "AUX I/O can be used to control an SCXI chassis and to sent and receive triggers", and that would be my prefered setup. What do I need to do?
Thank you for your prompt help.
Jerry.

You are correct, I had missed this detail of the SCXI-1127's
operation. Since you are using a PCI-4070, it is not possible to
use the PXI-1011 chassis with your current DMM. The best solution
I could recommend would be to use another device, such as a USB-1359 to
control the SCXI chassis, then the AUX Connector on your DMM will be
available to make the trigger connections needed for handshaking with
the SCXI-1127 switch. Keep in mind; however, that you will only
be able to handshake with one of your switches using this method.
I believe that you are already working directly with another Engineer
at NI, so I will allow him to assist you from this point forward.

Scanning with external DMM with Agilent 34970A using Labview

Hi,
I am a relatively inexperienced user of Labview. I have written a VI to
scan several channels on a 34970A using the 34901A multiplexer module
to take voltage readings. I want to use a more accurate DMM than the
internal one however so I have hooked up a Fluke 8840A to the agilent
and I want the scanner to simply switch between the channels while the
fluke actually takes the voltage measurements. How do I modify my
existing VI so that it uses an external DMM? One of the driver VI's is
'configure external instrument' which i assume is the obvious option
but i'm not sure where to insert this to modify the VI.
Thanks
Tom

What you do kind of depends on the capabilities of the external DMM and how fancy you want to get. If you at the section called 'Scanning With an External Instrument', you'll see how the connections can be made for an automatic scan. The 34970 will issue a trigger to the external instrument and when the measurement is complete, the instrument will send a signal back to the 34970 to close the next relay in the scan list. If you can do this, then the Conf Exteranl Instrument would replace the Conf Scan List and Conf Scan functions in the Advanced Scan Example. I'm not sure about the Conf Trigger but I suspect you would need to set slightly different parameters for that. The Read function would have to be replaced with a read of your external instrument. Some additional functionality may have to be added to take a reading after each relay closure if the DMM cannot save a series of measurements.
I had to once use an external instrument and didn't do any of this. The external instrument did not have external triggering or a an output that could be used to advance the scan so I just used the HP34970 Switch function to close a relay exclusively and a dmm read inside a for loop. I created an array of channels and the for loop auto-indexed them. This was simpler to program but the scan took a bit longer than what is described in the manual.

Data acquisition and frequency generation togather with PCI-6251 and LV8.2

Hi friends,
I am a new user of Labview. I am using LB8.2 with PCI-6251 .
I have to generate frequency and then measure the data and then for next frequency and so on.
i know that for this i have to use looping and that is not a problem. The real problem for measurement is to identify whether the frequency is been generated. if yes then measurements starts otherwise it should wait until it started. then after finishing the measurements send a signal to generator for changing the frequency and amplitude.
Now these two things {generation and measurement} togather are not working correctly for me. so i make 2 diff file, one for generation and other for measurements <by modifying the examples>. I can run both file togather and it works. But it need lots off effort and time. I have to measure from 10Hz to 1000Hz in 2Hz frequency step and i cannt leave in between .
can anyone help me how to syncronize these two togather .
Trying to attatch. both the files here ..
main_v1.1.vi --> for Measuring
Oscilloscope.vi --> for waveform generation

Problems scanning with HP printer and Mavericks

I recently installed the GM version of Mavericks and tried to scan some stuff and it came up with this error "An error has occurred saving the file because it could not be written to. Check the properties for the file to make sure it is not read-only." I tried repairing permissions and reinstalling the scanner software, but to no avail.....I'm not certain if it is because of Mavericks or something unrelated to that...any suggestions?

Hi burdell1,
As I am sure you know, OS X Mavericks has not yet been released by Apple. Gold Master is only a version of the Mavericks and was released to developers but not yet to the public. The HP software you are using is not compatible with the OS X 10.9, it was designed for the 10.8. This is likely why you are experiencing the issues you are having.
Maybe try scanning with he system preferences rather then the HP Scan software. How to Scan without HP Software.
Method one: Scan from Apple Preview
Method two: Scan from Apple Image Capture
Method three: Scan from Print & Scan
With any luck on of the above options will enable you to start scanning again. Hope the information I have provided is helpful!

Work with PCI-6052E and PCI-6601 simultaneously

Hi, I'm working with PCI-6052 for bufered data output and PCI-6601 for read two encoders at same time, when I work with single board I don't have problems but when I work both simultaneously I have a problem only I can out data or only I can read the encoders but not both at the same time. How I make this?

Hi,
You probably have one task in LabView running in series after the other. Both of these tasks require a loop. Your buffered data output needs to be written in continuous fashion in a loop (I believe) and your encoder measurements are being read constantly as well (should be in a loop). Try experimenting with these two suggestions.
I would copy both programs into 1 VI and keep them running completely separate. LabView will be able to assign each a different thread so they should be able to run completely in parallel. Therefore you would have 2 parallel loops that are not connected at all.
You can also create two completely different VIs and run them in parallel. There is no reason why the two different programs would interfere.
Hope that he
lps. Have a good day.

Scanning with Kodak i65 and Vista

Hi,
I am having trouble 'Creating a PDF from Scanner' with a Kodak i65 scanner. Everytime I attempt to scan a document with Acrobat 8 and Vista I receive a scanning failed message. The 'Scan Validation Tool' scans documents fine to the .tiff format however when I try to scan documents with Acrobat 8 it doesn't work and I get 'Scanning failed.'
Any help would be greatly appreciated.
Thanks,
Andrew

I have the exact same problem. Except I have the Kodak i30 Scanner. I have Adobe Acrobat Professional 8.1.2 (with the Security Update 1 installed).
In the past, I ran the following configurations on an older computer with no problems:
- Windows XP & Adobe Acrobat Professional 6.0 (with all of its various updates)
- Windows Vista & Adobe Acrobat Professional 6.0 (with all of its various updates)
- Windows Vista & Adobe Acrobat Professional 8.1.2 (with the Security Update 1 installed)
However, when I built a new computer, installed Windows Vista Ultimate, installed the Kodak i30 Scanner, I receive a "Scanning failed." error everytime I try to scan directly into Acrobat.
BTW, I HAVE "tried with latest Scan Validation Tool and firmware update from Kodak site." Updating the SVT and firmware neither helped nor hurt.
Has anyone had a successful fix to this issue?

Windows will not let me remove a bad version of the Firefox program so I can install a good one. I have an infected/malfunctioning Firefox. I have scanned with both Malbytes and SAS. I cannot remove the program so I can add a good version.

I received a trojan malware. I first scanned with Malwarebytes. Then downloaded the Super Antispyware Portable Scanner and scanned with it. I want to remove the once infected Firefox and install a new one, but when I click "Remove" in the Add/Remove program, it will not proceed.
How do I remove the once infected Firefox so I can install a new one?

Take a look at:

but you must delete the malware too.

Kollmorgen Motors with PCI-7342 and UMI-7772

Hi,
I am trying to connect a pair of third-party servo-motors (Kollmorgen AKM11B-ANCNC-00) and drives (Kollmorgen AKD P00306-NBAN-0000) using a National Instrument motion controller NI PCI-7342 and motion interface NI UMI-7772.
Ever since the setup has been connected to a new computer, the motors aren't moving even though they are connected. The motors are detected by the GUI for the motors (Kollmorgen Workbench) but the program shows that the hardware is not enabled.
It has also been noticed that the LED indicating 'Interlock' shows red, and so do the LEDs indicating the 'Disabled' for both the axes on the UMI.
The 'Axis Configuration' for both axes on the NI MAX program indicate 'Enabled'.
Since only the PCI board has been switched from the old computer (where the setup was working well) to the new one, most cable connections have been left untouched.
Any help/suggestions on why the motors aren't working is welcome.
Thanks in advance,
Subhabrata

Could you explain a little more on what you mean by 'current settings on limit switches' ? Anyway in accordance to the link you attached to the previous reply, we changed the settings on the NI MAX program to correspond that on the switch (on the UMI) and now we don't get the error (70119). Thanks for that.
But we still cannot get the motors to work. The 'interlock' light is still on. We took out the 'control' and 'feedback' ports that go into the UMI for the two axes and probed the voltage between pin 6 and pin 9 on the control port. One link (from the Knowledgebase) had suggested that we would get a voltage around 24V, but we did not. It was the same for both the axes. Does that suggest anything ? Should we look into replacing the cables connecting the UMI and the motion controller (even though the they were working fine before we moved set-up) ? Or could it even have something to do with the motion controller itself ?
Thanks in advance,
Subhabrata

Impossible to scan with à MP610 canon and a Airport express

I print with à canon MP610 on a Airport express, but it is impossible to scan withit.
help me .....

Sorry, but Canon and other manufacturers have not provided full featured drivers to allow advanced functions when their devices are connected to the USB port on the AirPorts......which is how I assume that you are connecting.
If you need advanced features like scan, copy, fax, maintenance etc., you will need to connect the All-in-One directly to your computer.
You might want to contact Canon Support directly to ask them if they plan to offer full featured drivers in the future.

Scanning with Image Capture and HP C4780

I am using Image Capture to scan photos from my HP Photosmart C4780.
When I "hide details" first an overview scan performs and then the scan performs and saves to the chosen folder.
When I "show details" I run into problems. An overview scan will perform in the same amount of time that it takes when I "hide details." However, when it performs an actual scan to save the photo, the time it takes to scan is much greater: approximately two minutes longer than above. Then, once the scan is complete it does not save the photo nor does it allow me to do anything within Image Capture. It simply shows a completed "scanning" bar and no photo in the background. At that time the only button available is cancel and nothing happens when I click it. (However, the cancel button does work if I do it in the middle of the scan.) Additionally, after quitting and reopening Image Capture I receive a message “Trying to open scanner session” then “Failed to open a session on the device.” The same problem persists when I shut down the computer and printer and then restart both.
I have tried reinstalling the HP software and drivers.
Also, I have changed the settings on "show details" and then went back to "hide details" to perform the scan and found that the new settings are applied. Therefore, I don't believe that it is the actual settings causing the problem.
I can scan using "hide details" since it seems to be a workaround, but I was wondering if someone else has had this problem, and/or if it is a sign that there is a bug somewhere that could mess up my scans. I'm planning on scanning lots of photos and wanted to make sure everything is working properly before I get too deep into this project.

Why use Image Capture when HP's software can do the same thing?

Will DAQ with PCI-4474 and a Kinemetrics Episensor ES-U sensor work?

We are planning to setup a DAQ system measuring some low level vibration. The system considered will be a PC based card, PCI-4474 and a Kinematrics Episensor ES-U accelerometer. Before purchase,we would like to find out is there any compatibility issue between these two devices or any complicacy in setting them up. Suggestions are welcomed. Thanks.

Hi Zenz,
I just want to ask how is your project going regarding the PCI-4474 and a Kinematrics Episensor ES-U accelerometer. I am using the same model of accelerometer from Kinemetrics but now it's power by an old ADC from Kinemetrics also. Now were planning to shift to NI DAQ including the power supplies. Were more on vibration testing.
Thanks

HP 6520 won't scan with wireless connection and new router

My printer scanned fine before. Got a new internet provider=new router and now I can't scan scan anymore. The computer is connected wirelessly. The computer says it cannot communicate with the scanner. Same if I try from the printer front panel, it says it can't communicate with the computer.
The router seems like the obvious cuprit, but nothing in the router settings or manual suggest anything that could be blocking the scanner communications. The router firewall is turned-off.
Printing works fine, and I can connect to the printer through its IP address. The user interface can see the printer status, check ink levels, everything. Everything works but scanning. I've re-installed software multiple times, tried turning off firewalls and tried HP Scan and Print doctor. It's not much help.
I'm at wits end.
-ETC

Hello @etcottle , and welcome to the HP Forums!
I see you are experiencing scan connectivity issues. I would like to help!
I would recommend powering down your computer, disconnect the power cord from the printer and the power outlet, and remove the power from your router for 60 seconds.
After 60 seconds, plug the router back in. Once the router has begun broadcasting, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
After the printer is on, re-run the wireless setup.
I'd also suggest this document:

Scanning with Epson RX500 and trying Image Capture

I have an Epson RX500.It prints and copies fine. It was scanning fine, using Photoshop Elements,for two years but now it is not recognized (I think this has something to do with updated Tiger 10.4.8. I've tried to reinstall the TWAIN and scanning software but that was useless. I've tried to use Image Capture but get the message when the Scan Setup opens up that "The scanner EPSON Stylus Photo RX500 is in use by another application..."
Can anyone help?

Eric,
There are one, or more files (plist, I think), that need to be purged, so that new copies can be made. I don't have those listed anywhere, that I can remember, but if you call Epson, a tech should be able to lead you through them. I only had this problem when I upgraded to 10.4, from 10.3, so memory is hazy.

Can't scan with snow leopard and canon pixma 850

I think I downloaded the newest driver but though I can print wirelessly I con't see my scanner utility so I can't scan. Ideas?

The inability to scan is caused by a limitation with the Airport device. The USB port of the AirPort Base Station and Time Capsule does not support printer utilities or other special features, such as scanning, that requires a direct proprietary connection.
