Can the progressive signal from the mini be coverted to interlaced?

Is there any way to make the video output from the Mac mini interlaced, because my HDTV will only accept 1080i?
Any help would be appreciated.

Yes, the mini for sure can output interlace. I have done this over an S-Video connection. What I am less sure of is whether it can also output interlaced video via DVI or VGA. In theory, there is no reason it shouldn't be able to. In other words, both those standards support interlace.
Programs like DisplayConfigX and SwitchRes X give you access to an interlace setting, but I have not ever had any need to try to use it over a DVI connection, so I can't tell you if it will perform the desired trick or not if that bit is set.

Why is the Analog signal from the FPGA is distorted?

Hi,
I am using the PXI-7831R board with LabView 2010. I'm trying to transmit TDMS files from the computer hard drive via the analog output of the 7831R. I've used the "Basic DMA output - R series" example and replaced the generated signal with a TDMS file. When I tried it on a synthesized pure sine file, it transmitted the positive part of the sine wave (which was a little distorted) but instead of the negative part I saw 0V DC. When I tried to use a "real" TDMS file (that I sampled earlier) the signal came out completely distorted. In both cases I used a graphic output in the host VI and checked that the data coming from the file is ok. Can anyone help me with that?
I would also appreciate some explanations on the "Update Rate" block (I suspect that he's the one causing all my trouble) - how am I supposed to use it and is it mandatory?
Thanks in advance.

It sounds like when you are using the sine wave, you are clipping the data. I am assuming that this is because you are sending it negative values. R-Series cards can not handle fixed point values, so try to offset the signal so that the lowest point of the signal is at 0. See how that works for you. As far as the Update Rate goes that controls the speed of your loop. If you do not set it high enough, the loop will simply run as fast as it can. I hope you find this helpful.

Does a second airport express extend the wireless signal from the first?

After a long search on his forum and not finding an answer, this is my question:
I have a Time Capsule connected to a Speedtouch router/modem. The Time Capsule has its own network. Because of the distances in my house, I use an Airport Express to extend the wireless range for my MBP. This doesn't seem to be enough to cover the whole distance (app. 35 meter) there is poor or no connection. So, my question is: can I use a second AE to extend the range even further? Will it pick up the signal from the first AE or do all the AE's in use need to connect with the Time Capsule?
The first AE is app. 12 meter from the TC.
many thanks,
Inge

Welcome to the discussions!
The answer is yes and no.
No, if you are using the "extend a wireless network" feature because each AirPort Express communicates directly to the Time Capsule, not to another AirPort Express. It's like the hub and spokes on a wheel. The Time Capsule is the hub and the Express devices are at the ends of the spokes. The devices at the ends of the spokes communicate directly to the hub, not to another spoke.
Yes, if you are using the "WDS" feature because this type of setup allows a "main", "relay", and "remote" device to be configured. But, there is a big penalty with this type of system:
o The network will operate at "g" wireless speeds only
o The bandwidth on the network will drop 50% for each "relay" or "remote" device. So, with two devices, the first cuts half of the bandwidth. The second devices cuts half again. So, you are down to only 25% of the original bandwidth.

How can I acquire signal from the 2 counters on my 6034e board?

I want to record one analog signal and one counter/timer signal with Diadem 8. I have a 6034e board. AI is not a problem, but when I define a counter in Diadem, for one of the two counters of the board, I get no or strange readings.

In MAX, I can only test one feature: pulse counts. So I connect a TTL signal between the source and the digital ground, and it counts a random number, of around 20-30 pulses, for each trigger. Same in Diadem. When I try period measurement (connected at the gate) or others with Diadem, I don't get anything.
I believe my wiring is correct as I'm used to counters with the PC-TIO-10 c/t board.

Laptop not able to get the wireless signal from the lightweightAP

Brief idea of the installation.
One WLC 5500 active -> second not yet installed
36 AP active, at the end they will be 45 (9 not installed)
Everything on the configuration look active and the light AP are registred to th
e WLC.
RF Channel definition done by WLC on all AP
Power definition done by WLC on all AP
Detection of rouge AP
But the laptops can't even detect the RF signal.
I try to detect the signal with 2 laptop which they where working in other sites with wireless in place.
We ara using 3 different application or client: Ippass, Odyssey, wiresquark Any of this application detect the signal.
However, on the WLC and on the light AP are up and running. Status up, channel and power automatic definition.
On the log I can see the detection of some Rouge AP around.

Did you enable "Broadcast SSID"?

Extreme Base station can't extend signal from Mini desktop ?TCP/IP settings

I have a Mac Mini connected to DSL via a lynksys 8 port workgroup switch. I had 6 rooms in my house connected to the router by ethernet wiring. Worked great for several years. Now 2 rooms cabling seems to have gone bad (mice or squirrels, maybe). To avoid rewiring the connection outlets or pulling wire again (Ugh!), we bought an extreme base station. It transmits the internet signal fine when connected to the ethernet network (roaming), but I cannot get it to allow clients to access the internet in WDS mode.
The base station is in a central location where there is not an ethernet jack. It picks up the airport signal from the Mini (with extreme card and yes, I have the MAC address of the Mini chosen).
Internet connection is "shared" on the Mini and the laptops have no trouble accessing internet within close range of the Mini. The laptops can't access the internet through the base station. I suspect it's how the TCP/IP is assigned. I have tried every possible combination in the Airport Admin Utility.
In the WDS diagrams, it always shows 2 or more Base stations, never a Desktop and a Base. Are these incompatible?

...but can't figure out how for the Mini....
When you select "Share your Internet connection with AirPort-equipped computers," click AirPort Options to give your network a name and password.
Since they are the "same" network does it matter?
If one has no encryption or is using weaker encryption it will be the weak link for others to access your entire network.
Normally, if you want to seamlessly roam between the 2 wireless networks, ensure that they are using the same network name (SSID), same encryption type, same encryption level, and same encryption password. However any wireless device connecting to the Mac mini's network will be on a separate subnet.
Now I've got to figure out how to get files off the Office Desktop from the laptops, should I set up afp for airport or ethernet?

How to output the digital clock and synchronization signal from the NI USB-6211

Hello,
I need to connect the NI USB-6211 to control a digital to analog convertor chip (AD5541). However, this chip requires three input signals :1) Clock input, 2) Logic input or a synchronization signal and 3) Signal Serial Data input (CS, SCLK, DIN).
how to output the digital clock and the synchronization signal from the NI USB-6211?

Hi SaberSaber,
You should be able to use the counters to generate a pulse train that could be used for clock and synch purposes.
Hope this helps. Let us know if you have more questions.

If I purchase a second Airport, will it strengthen the signal from the router in one part of the house , so that the printer, in a basement can see it?

I have a router in my upstairs, main floor of the house.   My iMac connects easily to the router, but the printer does not. If I purchase a second Airport, will it strengthen the signal from the router so the printer will connect wirelessly to the network?
I had the printer connected to the iMac by USB , but when I upgraded the iMac to Maverick OS10 my scanner no longer worked, the more I fussed with it the less productive it was.   Now the printer no longer is available at all.   The computer does not see it.
The message when I turn them on is that the USB is not compatible.    I unplugged the USB cable, and would like to connect wirelessly.
Thank you for any hints
Carol Havens

If you have an Apple router now providing your wireless network, you could add another....like an AirPort Express, for example....to "extend" the signal wirelessly and provide more coverage.
This is always a bit tricky, because the AirPort Express would need to be located where it can receive a strong signal from the main AirPort wireless router.
For example, if you need more wireless signal in a bedroom at the end of the house, you would locate the AirPort Express about half way between the main AirPort router and the bedroom.
On a side note......only the print function will work when you connect an All-in-One device to the USB port on an AirPort, so connect the All-in-One using wireless for full functionality.

What can I expect of my 4s with wifi connectivity. My 4s receive a signal from the same router I have always used. My 3G would pick up a signal throughout the house, and my 4s won't allow me out of the room. Is my new phone defective or just inferior.

4S at my house have stronger antenna than 3G iPhone. Reset Network Settings, tap Settings App>General>Reset, near bottom>Reset Network Settings. If still problem take to Apple for Warranty Coverage.

More generally, when you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
(You also can clear Firefox's cache completely using:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now")
(2) Remove the site's cookies (save any pending work first) using either of these:
While viewing a page on the site:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help?

I would like to tare (rezero) the input signal from a forceplate (glorified

I would like to tare (rezero) the input signal from a forceplate (glorified scale) so that the base signal is set to zero, e.g.: a button on the front panel that resets the signal to zero prior to getting a measurement from a subject.
We calibrate the force plate through labview and input our new equation into our scaling and mapping box which sets the signal to zero (or near zero) and the change in newtons (force reading) is accurate but when the application is closed and reopened the signal does not always start at zero (-400 to +1200 N), while the change in newtons is still accurate. I am NO engineer, I have Forest Gumped my way into getting some nice working VIs but I can't seem to find this function.
Thank you very much for your time.

Maybe that is the limitation of Acquire Input Data.vi.The vi can't identify the Unformal key.
You can try to use Event structure and set to listen "key down" event.
There are two terminals VKey, ScanCode will sent out the information when you press key.
There are two pictures in attached file, 2.jpg will show you the detail.
Good luck.

How can i use an ao card (pci 6723) to output data and to trigger an ai o acquire the data coming from the ao card?card (pci 6254) t

Hello
I am trying to perform AO (pci 6723) and to trigger my AO card (pci
6254) to read the data coming from the AO card. I am using LV7,1,
win2000.
Is an RTSI cable necessary or I can connect the trigger signals externally ?
I am using the LV example " multi function - synch ai-ao.vi" but i can't for some reason configure the trigger lines.
thank you in advance for your time.
Yiannis

Hello Yiannis,
If I understand you correctly, you want to synchronize your analog input and analog output that are started by a trigger on the analog input board. If you don't want to use the RTSI lines, your best bet is to export the AI Sample Clock and then read it in to the AO board. There is an example on ni.com called DAQmx - Synchronized AIAO Shared Clock. It appears to be having techincal issues so I have attached the example below. To export ai/sampleclock, use DAQmx Export Signal.vi after Get Terminal Name with Device Prefix.vi. Export Sample Clock to PFI3 (There are only connections between the sample clock and PCI3/4/8/9). Connect PFI3 on your AI board to PFI0 on your AO board (with a wire). Then change the source for the AO Timing.vi to Devx/PFI0. If you want to do triggering, stick the DAQmx Trigger.vi between the Timing property node and the DAQmx Start.vi on the AI task. I have shown how to do this in the modified version below. Please take a look at it and let me know if you have any questions. If you still get an error please take a screenshot of it and post to the forum. Have a great day!
Sincerely,
Marni S.

More and more photos progressively disappearing from the Book

Hi,
Please help me! I've invested a ton of time into this book and am hoping that someone can have a fix instead of me doing the book over. I've bought Apeture for the next time I do one, but please, please tell me there is something that can be done to fix this!
I uploaded about 700 photos to my library. Some of the photos came from the same camera and thus had the same names. I assumed this would be okay as I figured that iPhoto would append something to the name/not use the file name as the key/or however this thing works. I've also posted this as a bug and have tried all the things the genius bar people told me to do/had them do some of the things for me, though this didn't help.
Basically, after importing the photos, I put them in an album, sorted them, and deleted some of them, then I made a Book with about 170 photos in it, about 60 pages long, with several intro pages in there. During this process, I weeded out more photos from the book - I started out with more pictures then 170 and I got down to 170 by looking to see which look nicer in the layout and deleting the ones that were not as nice, just from the book, not from the album. I've also emptied my trash since then, both in iPhoto and in the trash on the macbookpro, to make room for the back up library later, to try to fix the problem as below.
Symptoms:
1. Thumbnail images in Book above page display when in page mode not updating the text on intro pages for days on end, despite a restart of the app, computer, rebuilding library, etc.
2. Pictures are progressively disappearing from my Book
Pages not updating - Thumbnail shows a page filled with pictures when in page mode, but when you are looking at the page itself, below the thumbnails, the picture is missing
3. The pictures in the thumbnails and the pictures on the pages when in page mode went missing - in both places
4. When you try to drag a picture that has disappeared into the book from the album, it "bounces back" - thinks that it's already in there. When you make a duplicate, you can drag the duplicate in (and this has been my pathetic workaround, which I am hoping not to do if you have something better!) And in any case, this is a bug and you should be able to replicate it by uploading pics with the same name, then moving some into the trash with the same name but a different photo then those in the book.
Anyway, I think that what's happening is that the Book is "confused" and thinks that the pictures deleted have been moved to the trash, when they really have not, they just have the same name. Somehow, the book is possibly ignoring the _copy that it's supposed to have in the name. Good grief! Help!

Ben:
Welcome to the Apple Discussions.
Thumbnail shows a page filled with pictures when in page mode, but when you are looking at the page itself, below the thumbnails, the picture is missing
What do you see if you try to view one of those "missing" image in the main library in the edit mode? Do you see a blank window with an exclamation mark in the middle?
If that's the case, that means that iPhoto has lost the link to the original file. Since you've rebuild the library and that didn't bring them back, I'm afraid your only option is to start over with a new library and import the original files from the old one as follows:
Creating a new library while preserving the rolls from the original.
Move the existing library folder to the desktop.
Launch iPhoto and, when asked, select the option to create a new library.
Drag the Originals folder from the desktop into the open iPhoto window.
This will create a new library with the same rolls as the original library. However dates on the rolls may be different but can be edited as you would the roll title.
Once this is completed you can delete the Originals folder from the desktop and the iPhoto Llibrary folder. If desired, you can keep the older library folder to try other fixes on it.
In the future I recommend you make a backup copy of the Library6.iPhoto file after each import and after doing a lot of editing and organizing in the library. Then if you experience a similar crash all you need to do is replace the damaged database file with the backup copy and you'll be back to the same place in the library as when you make the backup. See the tip at the end of my signature.
Hint: I create a separate library for each book that I create using iPhoto Library Manager. Then, like you, I put all of the photos I think I want into an album in my primary library and copy it to the book library with iPLM. I can add more at a later date the same way if necessary.
When the book is complete, ordered and delivered I burn that book library folder intact to a CD in the Finder. This gives me an archived copy of the library that I can use at a later date to order another exact copy of the book regardless of what I do to my primary library.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
