Data acquisition problem with NI-DAQmx 9205 and SignalExpress

Hi everyone,
I am using a NI-DAQmx 9205 connected via ethernet to my computer and Labview SignalExpress running to acquire data. I am working with EMG and I use an amplifier system from GrassTechnologies (http://www.grasstechnologies.com/products/ampsystems/ampsystems.html). The way it works is the electrodes are plugged on the amplifier system and the amplifier is plugged to the NI-DAQmx 9205.
I don't know how to setup the system to be able to read properly the emg signal on SignalExpress.
Does anyone know how to use it?
Thank you for youe help
John

Hi John,
If I were an Applications Engineer I'd probably be able to figure this out on my own but would you mind elaborating on your hardware setup a little? You mention plugging into a "NI-DAQmx 9205", however the NI-DAQmx is the data acquisition 'driver', the [NI]9205 is an Analog Input Voltage module. Do you mean to be plugging into a Compact DAQ or cRIO?
Also, I'm not familiar with EMG readings or the amplifiers/electrodes you're working with.
What is the signal type going into the amplifier from the electrodes, and what is the signal type and range (amplitude) of the signal coming out of the amplifier; AC, DC? I'm assume it's all voltage?
Straight voltages are pretty easy to work with provided you can scale it to usable units.
Lets get your hardware and signal types figured out then we'll be able to tell Signal Express how to handle those signals.

Data Acquisition problem with multiple length of commands and data received.

Hello,
I need to write a program to communicate with a Data Acquisition board. There are about 10 commads and each has a different number of bytes associated with it. For example command-1 has 4 bytes which need to be send to the DAQ, command 2 has 6 bytes, Command 3 has 4 bytes etc...
When the board responds back to the commands I send, it responds back with different number of bytes for each command. For example, When Command 1 is send to the board, it responds back with 3 bytes of data, whereas when command-2 is send it responds back with 5 bytes of data.
Each data byte received by my labView program from the board, needs to be displayed after some processing has been done. This processing may or may not happen on all the bytes of data got back.
I want the program to be scalable, so that if more commands are added later on, the display and the processing changes in accordance with that.
What will be the best approach for such a system ? I want the system to be dynamic, and dont want to repeat or re-write the code for each case statement ( case statements will be decided by the commands).
Any input is welcome.
Thanks,
birapxi

Hello Dennis,
That is certainly one way of doing it, but it is the brute force method. Is there any way to use clusters and add the data bytes coming in and going out to clusters. Also when the user sends a specific command out, can I use the unbundle by name function to send the bytes corresponding to that command.
For displaying the data received, can I follow a similar approach and use unbundle by name function to just display the specific data bytes for the command i have received.
Thanks for your input,
birapxi

Data Modeler: Problems with importin from DDL and Designer

I have a few problems with importing models from Designer and DDL:
1. Can I import spatial indexes from Designer or DDL file? An index does appear in the model but it doesn’t seem to be a spatial index. When trying to import from database, the index doesn’t appear in the model at all.
2. Is it possible to import sdo_geometry data types from DDL file? I haven’t succeeded with it, instead the column's data type appears unknown.
3. Sometimes import from DDL files (that are generated with DM) failed with nothing appearing to the model. I haven’t figured out why that happens. I didn’t receive any error message, the model just opened empty.
4. DM doesn’t seem to recognize public synonym creation from DDL. View log gives the following message:
<<<<< Not Recognized >>>>>
CREATE PUBLIC SYNONYM TABLE1
FOR TABLE1
5. Sequences lose their properties when importing from Designer. They only have a name but but start with, increment by and min/max values are empty in DM. Importin from DDL works fine.
I’m using data modeler version 2.0.0 build 584

Hi Alex,
There is newer version of Data Modeler (3.0 EA2) and it is free
You can download it from here

Video -data viewing problem with diadem 10.1 and 10.2, while ok in diadem 10.0

Hi,
When viewing a video in combination with data channels (we have 3 EEG channels, tdm data, that we watch in parallel), diadem crashed rapidly when playing the video and data together in Diadem 10.1 and 10.2. We do not have any problems with Diadem 10.0. so we keep on using the older version to avoid any troubles. This just to notify, since other people may have the same trouble.
Cheers
Else

Hi Else,
We'd really like to reproduce this problem and get to the bottom of what is causing it, so that you could upgrade in the future. Would you be willing to send me a data set consisting of your TDM, TDX, TDV, and video file? You can either post here or send it directly to my email at:

Hey floridiansue,
Do you have an installed email program such as Microsoft Outlook? If your email is through an online login, such as Gmail, etc, then one will have to create an email association with a program such as Microsoft Outlook on the PC for this Scan to Email system to function.

Data Roaming Problems with Lumia 610 and 710 phone...

Data Roaming problem with Lumia Wndows 7.5 phones. We have a Lumia 710 and also 610 phones on Virgin pay monthly sim cards. We cannot get data raoming to work on either phone. We have tried in a number of locations in France and Switzerland. Virgin confirm roaming and data roaming are set up on our account.
- I have purchased Data Passes.
- Settings>Mobile Network active network shows current operator
- Data Connection is on,
- Data roaming option shows "roam",
- highest connection speed is 3G,
- network selection is automatic.
- Flight mode is off.
- Account settings are ok because everything works on Wifi.
- Connection has been full bars showing 3G.
- I have tried hard resets of phone, manual network selection, deleted browsing history,
- phone software reports that it is up to date,
- I have run Network Setup which confirms phone has been updated network settings for relevant operator.
- Telephone calls to Virgin from Switzerland could not resolve the problem.
- Discussions with Virgin since returning home have not been able to solve the problem. It seems to be an issue with Lumia phones.
Can anyone help please? Nokia - why doesn't this work on your phones?

I'm like what an OS this phone has. All I can say is that if you own MS stock dump it fast as the OS on this phone is so bad its not even funny.
I think what they are trying to do here is a last ditch attempt to capture the online services market but it isn't going to work, because they have made this OS to weird.
I'm a pretty seasoned user and I generally am able to get gadgets to work but dudes this puppy is something else. I have 14 days to exchange it so Im going to give it my best shot for another couple of days and see where it goes.
The phone itself is pretty decent otherwise I would have returned on the 2nd day. Its pretty fast and the screen is nice and bright and if not some major concerns I wouldn't be a complaining.
1st} There is no way to import your bookmarks into the phone without using a online service.
2nd} I haven't been able to successfully export my old contact list from my LG P500 Android.
The 710 seems to only use contacts that are stored on online services even though I have imported my contacts using the Contact transfer function on the phone.
3rd)The phone won't shut off while charging even if you shut the phone down , plug it in and it turns on no matter what you do.
The Zune software is all glitter and no meat too unfortunately.
I really wanted an alternative and the phone is such good value and a local new Provider has a 27 $ a month unlimited everything, but luckily they have a 14 day phone exchange policy.
I'm going to keep for a few more days and see if I can get it to work the way i want it to.

Communication problem with Adobe 9.0 and HP Printer when I scan

I'm having a problem getting a .pdf file to come up when I scan from a HP 5610 All-in-one printer. Have uninstalled and reinstalled HP software three times but when I scan and want a pdf file it won't communicate with Adobe 9.0 reader for some reason. Is there a setting in Adobe reader that's a problem?
Thanks.

Thanks...found out that an HP5610xi All-in-One will not completely communicate with Adobe 9.0 Had to go to Adobe 6.0

I have an older version of Adobe Digital Editions (around 3 years old) and was very happy with it.
Then I had problems with my Kobo Reader and asked a friend who works in IT to assist. She could not fix the Kobo but she messed up my Addobe. She downloaded version three and I have an account and a password - was not able to transfer my books from my reader to version three (and I don't like the lay-out - I would prefer to stay with the old version as I also loose all my download date info..)
But all the books I have bought over the last three years are in the old Adobe Digital and I cannot access them any more. When I use it I get the message "that the document is licensed to a different account. I can't even open the books on my computer.
When I go to my Kobo library, I cannot also not open my books and get the message "this doc is protected by adobe digital rights management and is not currently authorized for use with your adobe. please sign in with your authorized adobe id and try again"
I believe the problem is that I do not seem to have a digital id for my old adobe or that the Kobo is not in sync with it anymore.
can you please help me - going on vacation in three days and cannot go without books.

I'm having problems with CS2 (mainly illustrator and photoshop

I'm having problems with CS2 (mainly illustrator and photoshop ) randomly shutting down while trying to save a file. Reformatted my laptop for fear of a virus and reloaded... I have gotten nowhere.
Please Help!

CS3 still had issues with the preferences becoming corrupt, so a possible workaround would be to reset the preferences.
The file is called AIPrefs and is located under 'Documents and Settings/User/Application Data/Adobe/Adobe Illustrator CS3 Settings'. It is a hidden file. Delete it with Illustrator closed and when you launch the program again the file will be rebuilt.
May be it is also sounds like you need more memory for your computer. If you can navigate to your computer's memory controls, and allow your operating system to use a portion of your hard disk drive (HDD) as RAM (maybe 2Gb or so) it may solve your issue.
How is about: http://www.filerepairforum.com/forum/adobe/adobe-aa/illustrator/383-%E2%80%8Bcorrupted-fon ts-in-illustrator-file-urgent-help-need – resource has non-commercial specialty

Apple TV keeps telling me there is a problem with my apple ID and password when I try to connect to home sharing. I have checked and rechecked and re-entered several times with same message.

I just bought an Apple TV and am trying to set it up. I am connected to wireless, is having difficulties setting time and date. When I try to connect to iTunes and sharing. It keeps telling me that there is a problem with my apple ID and password. I have quadruple checked and re-entered and it won't recognise it. What do I do? Dan.

Sounds like it is more an issue of connecting to the internet. Not just the WiFi Some people have reported that performing a power cycle on their Internet router solved this.

Very big problem with JSF about FORM and "id=" for HTML form's elements and

I have discovered a very big problem with JSF about FORM and "id=" for HTML form's elements and java instruction "request.getParameterNames()".
Suppose you have something like this, to render some datas form a Java Beans :
<h:dataTable value="#{TablesDb2Bean.myDataDb2ListSelection}" var="current" border="2" width="50%" cellpadding="2" cellspacing="2" style="text-align: center">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText id="nameTableDb2" value="#{current.db2_name_table}"/>
</h:column>
</h:dataTable>
Everything works fine...
Suppose you want to get the name/value pairs for id="nameTableDb2" and #{current.db2_name_table} to process them in a servlet. Here is the HTML generated :
<td><span <span class="attribute-name">id=<span class="attribute-value">"j_id_jsp_1715189495_22:0:nameTableDb2">my-table-db2-xxxxx</span></td>
You think you can use the java instructions :
Enumeration NamesParam = request.getParameterNames();
while (NomsParam.hasMoreElements()) {
String NameParam = (String) NamesParam.nextElement();
out.println("<h4>"++NameParam+ "+</h4>);
YOU ARE WRONG : request.getParameterNames() wants the syntax *name="nameTableDb2" but JSF must use id="nameTableDb2" for "<h:outputText"... So, you can't process datas in a FORM generated with JSF in a Servlet ! Perhaps I have made an error, but really, I wonder which ?

While I certainly appreciate ejb's helpful responses, this thread shows up a difference in perspective between how I read the forum and how others do. Author ejb is correct in advising you to stay inside JSF for form processing if form processing is what you want to do.
However, I detect another aspect to this post which reminds me of something Marc Andreesen once said when he was trying to get Netscape off the ground: "there's no such thing as bad HTML."
In this case, I interpret ungar's request as a new feature request. Can I phrase it like this?
"Wouldn't it be nice if I could render my nice form with JSF but, in certain cases, when I REALLY know what I'm doing" just post out to a separate servlet? I know that in this case I'll be missing out on all the nice validation, conversion, l10n, i18n, ajax, portlet and other features provided by JSF".
If this is the case, because it really misses the point of JSF, we don't allow it, but we do have an issue filed for it
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=127
If you can't wait for it to be fixed, you could decorate the FormRenderer to fix what you want.
I have an example in my JSF book that shows how to do this decoration. http://bit.ly/edburnsjsf2

I'm having problems with Flash Videos (Youtube and ESPN)

I have been having this problem for the last couple of days now and it is really annoying. Whenever I watch a flash video like on youtube or espn my computer freezes up and the audio will make a loud buzzing sound. I have attached a video with the post so you can see what happens. I don't have problems with anything else except this. I also get this error no matter what browser I use. I have system restored my PC as far as I can go, and I've ran a ton of scans and driver update checks and nothing seems to work.

merci a tous pour les nombreuses réponse. j'ai dû mal a les lire vue que je ne lit que le français. je vous remercié encore une fois amicalement. Blanchette 2.

I have a problem with my iPad 3 and iCloud.
First. When i try to turn on the automatico downloads of apps and music on my ipad ican't. I put on the buttons but they automaticly turn into off.
Second. I have an macbook with iWork and mi iPad has iWork too but i can use iCloud because the documents that i create in the iPad doen't go online.
I did a little research and i think the troubles are because apple didn't associate mi ipad with my apple id, i had retored mi ipad a lot of times and it doen's fix the problem.
What do i can do?
I'm sorry but i'm learning english, so i'm sorry if you have a hard time trying to understand.
Thank you

Hi Omar1510,
If resetting your iPad allows it to charge, but only temporarily, you may want to make sure that you have your data backed up and try restoring the device (you may want to test the charging before reloading your data). You may find the following article helpful:

Problems with LabVIEW 7.1 and lock-in amplifier Stanford SR530?

Does has anybody had problems with LabVIEW 7.1 and the instrument driver for the lock-in amplifier Stanford SR530?
With LabVIEW 6 there are no problems at all, but with LabVIEW 7.1 it is impossible to communicate with the instrument.

Here is the code and snippet. I had it from before. It reads Channel 1 and Channel 2 from the SR530, that is whatever the display is for Channel 1 & 2. You set the display manually or programmatically, I let you figure that part out.
