I have a PCI DAQ but my NIDAQmx detects a PXI DAQ
I work with linux Mandrake 10.1 and I have a PCI 6229 DAQ, I have
installed Labview 7.0 and NI DAQmx base 1.5Of2. When I launch the
lsdaq command the system found a PXI DAQ 6229 but my DAQ is a PCI 6229.
When I launch the DAQmx to configure a task there is the PXI DAQ in the
menu but the OK buttom doesn't work and I can't save a task.
Hi GICD-
NI-DAQmx Base will usually list plug-in PCI cards as PXI, but the card will still function properly when you program with the driver API. The problem you're seeing with the NI-DAQmx Task Configuration Utility is that M Series devices are not supported for configuration using that utility. For this reason, you will need to develop your application using programmatic task and channel creation as shown in the "dynamic" shipping examples from the LabVIEW example directory.
You may also be interest to know that NI just released the full-featured NI-DAQmx 8.0 driver for Linux. If you have the option to upgrade to one of the supported ADE's (LabVIEW 8.0 or C/C++ with gcc) I would encourage you to try the new driver for enhanced functionality and performance over NI-DAQmx Base.
Hopefully this helps-

How can I acquire data in a PCI DAQ board using a SCXI rack?
Hello.
I have an acquisition system that consists in:
· 3 PCI DAQ boards:
- PCI-MIO-16-E-1
- PCI-6052-E
- PCI-6034-E
· 3 cables to connect PCI boards and SCXI modules
· 1 SCXI chassis:
- SCXI-1001
· SCXI modules + terminal blocks:
- 4x SCXI_1121 + SCXI_1320 (for voltage analog inputs)
- 1x SCXI_1520 + SCXI_1314 (for strain gauges)
- 1x SCXI_1530 (for accelerometers)
I have been trying to acquire different signals (specially voltage signals that are easier to reproduce) but I haven't been able to do it. I can't read anything from MAX or LabView. I have tested the PCI boards with a SCB68 terminal block (without any SCXI component) and they work properly. Problems appear when I use the SCXI chassis and the SCXI modules. I don't know if there is a problem with the hardware or it is a wrong configuration.
I guess channels in the SCXI modules correspond to analog input channels in the PCI board they are connected to, but I don't know if I have to read data from analog input channels of the PCI boards or from SCXI channels that appear in MAX (I have tried both posibilities, but they don't seem to work).
I don't know if I have to use Differential, RSE or NRSE configuration. I have tried all of them. Sometimes I only read noise, sometimes signal is fixed in a limit value (maximum or minimum, it depends), sometimes it's fixed in a value near zero,... I have changed connections and configuration options so many times I can't exactly say when one thing or another happens.
I have tested only one PCI board with only a SCXI module in order to avoid interaction and confusion. Nothing.
I think I have tried changing almost every option in MAX, but it doesn't work.
I'm sure I'm missing something and solution is quite simple, but I can't find it.
Can anybody explain to me how to connect and configure my system to read any signal? I only need a few steps or highlights. Maybe some clues about what the problem can be.
Thanks!I have several comments and suggestions:
A) Have you "added a device" in MAX and actually added the SCXI chassis? This step is necessary to get the chassis to work. Click on "add a device" and choose the 1001 chassis . Do this for one DAQ card and one module only initially. The Set Up wizard should walk you through the configuration. If you are unable to add a chassis within MAX, I suspect the chassis is not working correctly.
B) Once configured, you can examine the SCXI channels in MAX as follows:
1) Open the DAQ card in MAX and Open the Test Panels
2) For the SCXI channel to view, use the following convention OB0!sc(n)!md(m)!ch where the letter (n) corresponds to the chassis number in MAX (usually = 1), the letter (m) corresponds to the module number (slot) where the module is located in the chassis, and (ch) represents the channel(or channels) you wish to view. So presuming chassis ID=1, and a module in slot 1, and you wish to view channel 3, you would type the following in the channel field for the DAQ card channel to view:
OB0!sc1!md1!3 (note OB0!sc1!md1!3:6 will display channels 3 through 6)
All of the SCXI channels for a given DAQ card are multiplexed through channel 0 of the DAQ card, Channels 1 and up are not used, hence the initial three characters in the SCXI call refer to "On-Board Channel 0 (OB0)"
C) For the subsequent set up, it will be necessary to first add the additional modules to the chassis (when powered off). Then open MAX and update the chassis. (If you get an error then simply delete the chassis reference in MAX and add a new chassis). You will then be required to set the interface mode of each module as either parallel or multiplexed. In parallel mode, you associate a distinct module with a distinct DAQ card in the host PC. For those DAQ cards that will address multiple modules, you must first configure the modules to be in adjacent slots in the chassis and then assign the first module to the cabled DAQ card - then all of the modules assigned to that DAQ card should be configured in "multiplexed" mode.
D) Once the chassis has been properly configured, you can click on each module and set the gains, filters, and terminal block types.
I hope that this helps to get you started. -
Controlling Brushless maxon DC motrs using NI 6221 PCI Daq card
Hi ,
I have a NI 6221 PCI Daq (M Series) card. I need to know how to use it to control a brushless DC motor from maxon with digital encoder? Also I need to know how to access the daq from matlab 7.0 as i am not familiar with labview and i need to know where i can get the matlab drivers for the card. Also i am trying to learn labview in the course of time. So it would be great if someone can give me some good tutorials in labview for motor control.
Thanks

Message Edited by venkata83 on 11-24-2005 03:30 PMThe lowest cost servo control option from NI is the PCI-7342 board which allows you to control two servo motors.
Please have a look at the datasheet for a detailed description.
Both, the 6221 and the 7342 provide synchronisation capabilities through the internal RTSI-Bus interface. This makes it easy to correlate e. g. analog values and motor positions.
As the 7342 doesn't provide power you will need to connect the board to an external drive.

RS-485: PC can send/receive data from PCI card, but LabVIEW can only send to card.
I have a master/slave setup with a 2-wire RS-485 connection via a StarTech PCI2S485 card http://www.startech.com/product/PCI2S485-2-Port-PCI-RS-422-485-Card-with-DB9. A Vista PC running LabVIEW 2010 is acting as the master to 6 slave devices. I am running a driver VI supplied by the company that made the slaves.
I've used a terminal program called Termite to monitor the ports during operation and have concluded that both the PC and the slaves are sending correct data packets (i.e. correct protocol and reasonable data). Termite indicates that the slave's response is being received by the PCI card, but the problem is that LabVIEW simply isn't reading the response from the card. Each time the driver VI is run it returns a "timeout waiting for slave to respond" error.
The VI and slaves I am using are designed for both RS-232 and 485 communication. I've verified the VI to run in 232 mode on a different COM port. I also wrote a simple VI using the VISA functions to test the ports on the PCI card, but I've had the same results. Hardware connections have been looked over carefully, but the fact that the card actually sends a correct message and receives a correct message indicates a different problem.
Any idea why LabVIEW can talk to the PCI card but can't hear it? Is there anything I can do about this, or does LabVIEW generally not like StarTech's PCI2S485 cards?
Thanks,

RS232 interface consist of 2 indipendent communication crossed lines between 2 devices (9DSub connector: Pin 2-RX Pin 3-TX pin 5-Gnd)
RS485 interfaceis a bus, shared between 2 or more devices. (like ethernet or CAN Bus)
This means that an incorrect use of the bus can lead to a "packet collision" if 2 or more devices try to send a message on the bus at the same time or at least their messages, partially "overlap"
About 10 years ago I have used a PCI 2 RS485 port: I remember that I have to change the status of RTS serial control line to switch between transmit and receive mode.
This can be done using the serial VISA property:
Serial Settings --> Modem Line Settings --> DTR State
or using the VI
<LabVIEW dir>\vi.lib\Instr\_sersup.llb\serial line ctrl.vi (LV 8.6.1)
The result was that the slave device connected, send me the response after few nanosec. causing the lost of the answer.
because LabVIEW use more than some nanosec. to change RTS property after sending message on the 485 bus calling a VISA Write.
So for me there was 2 possibilities:
- use 2 RS485 port (1 for transmit 1 for receive echo transmit included)
- use this converter
http://www.advantech.com/products/ADAM-4521/mod_2E78D425-8B08-43F6-81B0-1B924E53E075.aspx
this converter, after sending a message on the bus, electronically switchs back to receive mode without losing a byte.
But the question is :
what does it means
"RS-485 mode supports Auto Transceiver turn around (ATTA)"
of your card?

How can I connect my 3gen apple tv with HDMI to my BUSH LCD32TV022HD
This does not have an HDMI port but does have:-
1) S-Video I/P,
2) Video I/P,
3) Audio Input (Left & Right)
4) Audio In jack (for VGA and DVI source)
5) DVI input
6) VGA inputWelcome to the Apple community.
The Apple TV doesn't officially support a DVI connection, however you may be able to get it to work. You will first need to check that your TV supports either 720p or 1080p as well as HDCP. If you are able to get the video working over the DVI connection, you may also require a DAC in order to connect with Apple TV's optical audio output to the TVs audio imput.
You may well wish to make sure that the DVI connection works before spending any money on a DAC.. -
About 2 weeks ago I plugged my wife's iphone 4S to our pc to update it to IOS 7and backup her iphone info to icloud. When I was done my wife's iphone had my daughter's ipod info on it and I can't find my wife's info on icloud anywhere. My wife has about 6 years of business contacts on her iphone so she is rather upset. Is there a way to recover her contacts?
You don't have to wipe anything, but when you get a chance make sure you backed up to icloud.
What that means is your contacts inside of the phone either physically or liquid damaged. To check
which, you can look inside and if you see a little pink, that would give you a water damage. If you don't
see pink it means that you to many times plugged in that charger the other way or tried to. May be
used some other things to plug in. If you flash the light in you may be able to see those contacts.
If I were you, i would not believe me, good luck! -

I have so many questions but I guess I can only ask a 4G one here-.
Hello-
I have a basic MOTO phone that was free when I signed up with Verizon 3 years ago and after I wanted internet access when I was traveling I purchased the Mifi2200. Now, when I sign in it says I can have $30 for the New Every Two for the phone (I do not understand how I can get a decent phone for $30, but at least I have something since I hear they are getting rid of the New Every Two. Moreover the MiFi 2200 account is due for the New Every Two and a product upgrade (whatever that means) too. I heard the New Every Two amounts are going away so I better use them (They might have already gone away)
In looking for a smartphone or an iPhone (I have never had either or text messaging or a phone that can hook up to the internet), but my main questions here is about this 4G. I will just spell the questions out and hopefully some should will feel sorry for a person like me who does not understand most of the techie stuff and really has a hard time using it. But here are my questions.
1. What is the difference between 4G and 4G LTE?
2. Why are they selling 4G USB devices, phones, notebooks, etc. if the 4G (I will use 4G to mean both 4G and 4GLTE since I assume the 4G LTE is a better service) network is in such a small area of the country besides every airport? When I read about 4G devices to surf the internet, I keep reading posts that say if you have a 4G device and 4G is not available or you are traveling and going in and out of 4G areas, that the connection is dropped if you were hooked up with 4G and suddenly entered a 3G area without 4G. This seems like a major hassle and I am wondering if this is true?
3. If I purchase a 4G device will it automatically connect to the 4G network if it is available or do I have to know if it is available or not and connect a different way depending on if 4G or 3G is available?
4. does anybody know (I have asked Verizon and have been told no, but I seem to get random answers for most questions I ask Verizon employees) if 4G phones are avalable and if so does the user have the same problem when they are on a call and go in and out of 4G/3G areas? (as far as calls being dropped or can the device switch automatically without any trouble)?
5. If you were interested in a 4G or 4G LTE device and you did not have 4G on your area would you wait until 4G is available in your area or would you go ahead and get the smartphone, data device, or whatever you need now and just use it and wait until the 4g network is up in your area?
thanks a ton for any help. I really appreciate it. I am not sure of I should use the New Every Two for the MIFi2200 and get a 4G usb device for my macBook Pro and use my new Every Two and product upgrade for either a smartphone or an iphone and if you think I should get the iPhone should I get the one from Apple or the one from Verizon, or does it even matter? I keep reading that Verizon's iPhone which uses something like CDME is nowhere near as good as ATT's service which can take talking on the phone and looking up something on the internet at the same time, and other things that I did not understand.
If you would not recommend I get the iPhone, what are some of the good smart phones that have apps available and are relatively easy to use?
(Not sure why but when I clicked "Post" the Message flashed and this appeared in red at the bottom; "Your post has been changed because invalid HTML was found in the message body. The invalid HTML has been removed.")OOOKAAAAYY; Your devices are over my head. The smart guys, Verizon & others, should be on the job tomorrow -Monday and you'll get better feedback.
I noticed that large parts of Salt Lake City are 4G. Zero in on the coverage map (refresh "4G data") and you'll see where you sit.
The only person I know who stays connected while traveling (or tries to) is Toughbook. I just re-connect the best I can where ever I am.
A little confusion: The 4g network -see map- is "4G here, 3G everywhere else"
The "old" usb760 3G network, though still in place, is 3G everywhere 4G nowhere.
The hardware(s) match two entirely different networks. You've gotta buy all new hardware to go 4G.
and, unless you want to pay for two plans, your old stuff is useless. I can't whip out my old USB760 and connect with it anymore. It's a Whole new game. I'm committed.
I like thePantech when I'm in 4G, but sucksfor me when I in the 3G hinterlands. The other hardware choice is the LG VL600
I don't know anything about the phones, but my earlier comment about Verizon rumors not helping comes largly from several discussions raging like this one. Happy Hunting. -

My ipad just won't let me sign in with my apple password on FaceTime or iMessage since updating to ios7 it says check my network connection, even though my iPhone works fine with the same password, can anybody help please, I have tried numerous things but nothing works. Will I have to wait for a bug fix to sort this? I hear they are working on one a the minute, I hate ios7
Try a Restart.
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
Resetting your settings
You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple.
Here is a link to their contacts with most of the information below.

i have purchased itunes match but the cloud will not load on my ipad 4.it works on my iphone 5 & it originally worked on my ipad.the only music that will show up is stuff that i bought from the itunes store.any ideas on how to get this to work?
On the MBP, in iTunes, switch to Song view and enable the iCloud Status column by pulling down View > View options and selecting the option for "iCloud Status." Close the small window. Look for any tracks that have a status of "waiting." If you see several of them disable iTunes Match while holding down the Option key. Quit iTunes, wait a few seconds, then open it again and turn iTM back on. Let it compelete the scan. Wait until all tracks that are "waiting" have a status of either "matched" or "uploaded."
On the iPad, turn off iTunes Match then launch the Music app and let the contents clear out. Power cycle the iPad for good measure, then re-enable the service once all the tracks in iTunes have been processed. -

So i went to transfer purchases and It wouldent let me. So how do i transfer my purchases before i restore my ipod so i can back it uup so i dont lose everything. Thanks
There is a backup plan after doing the Restore. Read this.
