Reading status of camera's connected to CVS

i have 3 cameras connected to 1 CVS.I want to read the status of the cameras whether they are healthy or not and also the CVS status to display in PC at remote location. So, how i can access(read) this data from the CVS into the labview software to generate fault message or output as alarm. please suggest us the solution.

When using LabVIEW RT all VIs are targeted to the CVS and executed by the RT Engine. The RT Development System (your remote PC) displays the front panel of the VI while the RT Engine executes the block diagram code. Therefore, to determine if the cameras connected to your CVS are "healthy", check for acquisition errors from the cameras (such as a timeout error) in the VI running on the CVS, and then illuminate an LED or display a message on the front panel of the remote PC if an error occurs.
You could also use something called a watchdog timer to monitor software on the CVS and to take action if the software is not responding. The watchdog timer is described in more detail on page 4-10 of the Compact Vision System User Manual and in the tutorials below:
NI 1450 Series Compact Vision System User Manual
Developer Zone Tutorial: Software Watch-Dog Timers
Developer Zone Tutorial: Using a Hardware or Software Watchdog in a Real-Time Application
I hope this helps! Best wishes with your application.

Image Capture connects to card reader but not camera

Image Capture and iPhoto do not detect new connected Canon camera. Will read card via card reader. Camera will connect to older macbook iPhoto and Image Capture but not my iMac. Image Capture in Mountain Lion has no perferences anymore. Tried Repairing Disk Permissions but no success. Any ideas?

Sorry, there is no setting on the AirPort Extreme card built-in your new iMac that can be tweaked to "force" a connection to the Netgear's "n" network.
Does your Netgear allow for different Network Names (or SSIDs) for each of its radios? If so, you can try an experiment by renaming the 5 GHz radio's Network Name, and then, specifically connect the iMac to it.
Also, since "n" can operate on either radio, it appears that your iMac is "locking" on the 2.4 GHz radio. Does your iMac have any trouble connecting to any other "n" Wi-Fis? If so, then there may be a problem with either the AirPort Extreme card or the internal antennae on the iMac ... and it would warrant a visit to your local Apple Store to have them take a look.

Lightroom opens when a Card Reader or Camera is connected [Windows]

Issue: Photoshop Lightroom opens each time a card reader or camera is connected, or an all-in-one printer is turned on.

Don and John,
I must be dumber than I could possibly look, but I do thank you both for your help.
Don, I have already checked and un-checked that first check item in "import" under preferences, to no avail. I have crossed refferenced it with my MacBook and regardless of whether it is the same or different the problem still occures.
John, I will admit to being smart enough to change from PC to Mac relatively recently but appear dumb enough to not being able to discover how to set the Mac to do nothing on card insert as you describe.... could you advise please.
Many thanks

I think the McAfee suite will do the trick when I pay them a one-time fee of $69 or $179 for a year for unlimited support.
Your call of course but IMO a waste of money. Please read this first:
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.

Camera Window pops the message "Cannot detect Camera, Check connection to camera, then retry"

I have installed Camera Window in my Windows 8.1 laptop. The moment I invoke Camera window, there is a popup which shows . "Cannot detect Camera, Check connection to camera, then retry. I do not have this issue in my iPAD though. Has anyone come across this issue..?Thanks

zebah_alfred,
Please make sure you have the latest versions of the software installed by downloading them from our website. Please click HERE to go to the download page.
1. Are you connecting to your computer with a USB cable or over Wi-Fi?
2. Are there any other devices connected to your computer other than the camera, aside from a keyboard and mouse of course?

Is there a comprehensive list of compatible cameras to connect via firewire?

is there a comprehensive and up-to-date list of compatible cameras to connect via firewire that will work with FMLE?
I saw this -http://www.adobe.com/support/documentation/en/flashmediaencoder/FME_DeviceMatrix.pdf
but it's out of date and limited in scope... any more information?
thanks
Josh

I'm in the process of trying to get this information for a client. Even with a paid AppleCare agreement, the only answer I'm getting is "look in the forums" and "look on the developer site" (although I have to give credit to the Tier-1 rep who's trying to help me.) The impression I'm getting is that they consider an exact list of header names to be proprietary information for some reason, and are going to great pains to try not to give out the information, but also to not create ill will amongst their customers by explicitly saying "that's proprietary".

Importing from camera into lightroom when camera is connected

I used to be able to import photos into lightroom when my camera is connected. I somehow am no longer able to do this, maybe because of updates, but I am not sure? I am using version 1.3.1 on a pc running windows vista professional, and my camera is a Canon Rebel Xti. The problem I have is that using windows to import is too slow and it has caused duplicate filenames of files. So I'd love to be able to have lightroom import from the camera like it used to. Cheers

Hello. I've seen photographers have portrait setups that have the camera connected to the computer, and as soon as they take a picture, the new image is imported.
I tried using "auto import" but it's not working properly. I'm shooting Nikon D200 and it has 2 USB modes: P2P and Mass Storage. In the former, I can't have "auto import" on because it needs to read from a folder and it's being read as a "device" instead. In the latter, I'd have to disconnect the camera to take the picture, reconnect it, but it doesn't detect a change (new picture) and so it won't auto-upload. I also have Bridge CS3 which I believe should do what I want it to do, but can't find it on there either.
Does anyone have a solution?

Read/Write problems with multiple connections using MySQL & Tomcat

hello all,
I am developing a web-based java application that runs on a 4.1 tomcat server and uses MySQL 3.23.52 as db server.
this program uses hundreds of tables with hundreds of rows each.
when two or more users are connected, we are experiencing several problems:
1. when a query is started, they get cross-results that come from both connections.
2. when inserting/updating (most queries are long and take a few seconds), sometimes data are crossed too, sometimes they are saved incorrectly but get no error message, sometimes they are not saved and get 'null pointer' sqlexception (but tables and queries are correct).
3. using SHOW PROCESSLIST and SHOW STATUS, we saw that MySQL server hosted no more than 3 max_used_connections, even when my.cnf parameters where set with more. when 3 or more users try to access the database, they get a bad handshake error until other connections are freed.
any suggestions?
thanks

I am not using a connection pool. I read that when two different connections try to access the same data simultaneously, mysql is not secure. maybe a connection pool could solve that? or maybe is it a mysql limit?

IMAP Read status - 1.3.5

On 1.3.1 and prior versions of the webOS I was used to the READ status of the IMAP messages coming into the pre almost immediately. Now it seems they stay up until another message comes in.
Let me give you an example:
You have your pre on the Touchstone, so you can see your alerts, new mails, etc. I used to be able to rely on that screen to see new email as they came in. When I read the message on my desktop, within seconds the message notification would remove itself from the Pre as it was marked READ on the IMAP server. Now the message notification appear to stay live until another message pushes them away.
It appears the IMAP IDLE functionality has changed. Has anyone else noticed this?

Post relates to: Pre p100eww (Sprint)

There was really only one thing I was hoping that 1.4.0 would fix and it was this incredibly annoying bug that was introduced with 1.3.5. It is still present in 1.4.0! Now with LED notifications finally officially supported (which I'm really very thankful for btw) this issue has become more irritating than ever, the phone will continue blinking for emails that have long been read elsewhere.
When can we finally expect a fix for this?

How to get status of an rs232 connection

Hi,
I am trying to read out the status of on RS232 connection.
How can I do this?
Moreover would it be great to make the handshake visible! Is there a way that I can do that?
I would like to make a program something like where I can push a button "connect", get the status that i am connected and then make it possible to send some data....
I would really thank you if you can help me.
Sincerely Tim

The more fundamental problem is that except for an indication of whether or not it has been initialized and perhaps the number of bytes in the port buffer, a serial port doesn't have any sort of real status. RS232 communications simply isn't that sophisticated. For what it's worth, unless the device you are working with is very old, monitoring the handshake lines probibly won't tell you anything because most modern serial device don't use any handshaking.

Can't see mounted volume of my Canon G9 when camera is connected via USB

Why can't I see mounted volume of my Canon G9 (with 8GB SD card) when camera is connected via USB. I just want to be able to download the movie files. Aperture does this fine on my other Mac but on my MBP I use Lightroom and it does not automatically download additional files a la Aperture.
Also can't read via Kensington Multi-SD reader but suspect that's because it is a little older and does not support the higher capacity SD cards

Digital cameras have several modes in which they can connect to a computer.
One mode is sometimes called "Mass Store". The camera acts like a USB disk or thumb drive. It appears in the Finder and files can be copied from it. This obviously is what you are looking for.
Another common mode is called PTP (Picture Transfer Protocol). In this mode, the camera will not appear in the Finder. You use special software to select and transfer the images. There are many applications available to do this: iPhoto, Aperture, Image Capture, the software provided by the camera's manufacturer.
Consult your camera's manual to see if you can select the mode. My Nikon cameras can be set to either of the modes I mentioned. I think I have heard that Canon supports PTP only. I don't have a Canon, so I can't verify this. In that case you could use Image Capture, or Canon's software, or use a card reader. Card readers are usually faster than the camera anyway.

Camera not connected in macbook air ios 10.6.8

Camera not connected appeared in my macbook air when I tried to access camera booth yesterday. This happened in late 2011. I took the macbook to an apple service centre and was told that it was a hardware problem. I delayed sending it for repair and in the meantime in february 2012 there was a camera update which I installed and that solved the problem. Lately I had installed several updates and now I am faced with the similar problem of "camera not connected" when I tried to access photobooth and all the other applications that require a camera. I need help as my extended waranty is about to expire in a few days time. I have not much confidence in the macs as I find that the camera goes missing after updates? Please help! Thank you

You need to take it into an Apple store to be fixed. You should of done that back when it first happened. I suggest you do it before your Applecare warranty runs out.

IPhoto launches when a camera is connected

I recently installed the newest version of iPhoto, and on the first startup it asked me if I wanted "iPhoto to start when a camera is connected to the computer". I mistakenly pressed "yes", and now I can't find anywhere in the preferences where I can turn this feature off. I'd much rather organize the photos on my hard drive before importing them to iPhoto, so I would appreciate it if this feature could be turned off.

Hi A,
Using Image Capture to download images and video clips:
Open up Image Capture which is found in the Applications folder.
When it is opened, go to Image Capture/Preferences
Under the General button choose
Camera: When a camera is connected, open Image Capture.
The next time you connect your camera Image Capture will open.
In the window that opens you will see an Options button. Click on that button to set your options.
To find out more about Image Capture (it can do a lot more) Click on Help in the menu bar when Image Capture is open.
iPhoto: How to Change the "Open Automatically" Preference
If you find you can't change any of Image Captures preferences or can't access any drop down menus or they are greyed out, check to make sure Image Capture is loose in the Applications folder and not within a sub folder.

Can't connect any CVS server

I can't connect any CVS server. every server i tried to download from , for example, when I compile from aur or abs I get "Connection timed out.
even in arch CVS:
$ sudo abs
Password:
Cannot connect to cvs.archlinux.org: Connection timed out
Cannot connect to cvs.archlinux.org: Connection timed out

I'm sure that I'm connected to the web.
How can I check the CVS port? I don't use firewall.

IMovie and Sony camera can connect, but nothing imports

My iMovie and Sony HD camera can connect fine...I can control my camera from imovie, but when i click import, it plays (plays on camera and timer on imovie starts) but the screen remains blue and no video is actually imported.

Did you try Sue's excellent suggestion of the Garage band trick anyway?
Also, try deleting iMovie's preference file...the plist found in YourUserName->Library->preferences->com.apple.iMovieplist. Close iMovie, trash the plist. iMovie will create another one when you launch iMovie again.
Do you have the camcorder plugged directly into your computer's Firewire port? Some camcorders don't work properly if they are connected into another device. And, just to be sure, you do have the camcorder set to VTR, right?
