Any technique to use two instruments vi together

hi,
i am using labview to control arc monochromator and photon counter. i want to know is there any technique that i can use in lv 8, so that i dont have to control this two instrument with two differrent set of vi. That mean there should be one vi to control all the setting of this two instrument and this all process works in synchronization.
if it possible how can i do that?
josan

Of course. You just have to put the VIs you're using now into a top level main VI and create controls/indicators for the subVIs. Any VI can be a subVI to another VI.
There are hundreds of shipping examples that have subVIs in them. You might want to take a LabVIEW basics course. Go to http://www.ni.com/devzone/lvzone/fundamentals.htm and check into the various options including official training classes, books, and on-line tutorials.

Is there any way to use two video resolutions in one project in Pre10?

i looked up this question but didn't find what i was looking for. Pre10 on XP or on Win 7 64 bit( i have Pre 10 on two machines) both with lots of RAM. XP has a dual core processor and Win 7 64 has a quad core.
I shot a concert video with a Sony HDR-XR160 (1920 x1080 16:9) on tripod in back of room for my main camera and used a Panasonic Mini-DV as my roving camera (640x480). i am using the HD on video/audio 1 in timeline and want to use the Mini-DV on v/a 2... but when i cut to the mini-dv footage it plays fine but I see the edges of the HD footage on both sides.... is there any way to make this work??
can i resize the mini-dv footage or will that look weird? should i make a new project and make it 640x480 and what would that do to the HD footage? I thought that the 640x480 footage would look cool as cutaways as it's different res.
(I have another question. in Pre3 i could click on a video track and hold the alt key and use the arrow keys to shift the video track right or left by a frame at a time and that doesn't seem to work in Pre10 I have a matrix audio track to sync with the video. do you want me to start another thread for this question?)
thanks

If the SD material is not filling the Frame, which will happen in an HD Project, you will then need to Scale the SD footage to fit. This is what Steve was warning about, as the Scaling will degrade the SD material. One possible option would be to use a program, like Red Giant's Magic Bullet Instant HD, to do the Scaling. While still less quality, than having shot HD to begin with, many users find it pretty good for the up-rezzing.
Good luck,

How can i use two monitors in my application?

Hello,
Background
I have a dual monitor card and two monitors which I want to use in my LabView application. The application gathers data from a complex sensor and calculates a number of results which need to be displayed graphically, this happens every 10 seconds or so. There is an awful lot of graphs which may be needed to be seen at some time but not routinely. The idea is that one monitor will display all the standard routinely displayed things and will not have any user input whilst the second monitor will display a tab control which has all the other graphs pickable.
Question
What I want to know is how I can programmatically tell labVIEW to put one vi up in one monitor and another vi in the other. I would then have them both maximised (which I know how to do). I would rather have the monitors set up as individual and that way I could keep the windows control bar on one monitor only. Thus one monitor would be a true user interface and the other simply a display.
Basically how do I tell LabVIEW to use one monitor for a specific vi and not the other.
The card I have is a matrox p650. Any comments would be appreciated.
Regards
Kevin

Hallo,
with new version of LV its more easy, but it also hasn't any troubles with LabVIEW 6.x or 7.x.
Especially with Matrox P650 you will get no any problems (we using
exactly this card together with G550 and our application supported
three monitors at the same time.).
I recommend to you following sequence:
- After installing driver turn on option for supporting different
resoluton on different monitors. As result you will get two absolutely
separate monitors.
- In Windows define which one is primary and which one is secondary.
(On primary monitor located taskbar and all messages dialog boxes will
appear.).
- Arrange secondary monitor in display properties - where he located (left from primary, or right)
- In your VI (which must appear on second monitor) use
FrontPanel.PanelBounds Property Node for positioning. You must set four
values for two corners. Easiest way to found right values is following:
read this property node in while loop and put indicator on front panel.
Then run VI, drag front panel onto second monitor and resize if
necessary, and then you will see right values for PanelBounds. You can
write this property node programmatically in run-time too.
hope it help,
good luck.

Using two displays with Mac Mini

Is there any way to use two seperate monitors with a mac mini-primary and secondary? If you find a device, please let me know

I had seen this blog a few months ago. They used a Matrox DualHead2Go with two 1024x768 capable monitors to achieve dual screens
http://voice.firefallpro.com/2006/02/mac-mini-dual-monitors-using.html
You will have to add a custom display / resolution using SwitchResX in order to use them both, but it works.

Two graphics card together (eGPU)

Hi everyone,
I'm trying to use two video cards together. I don't want to switch between / use only one of them... both should be ON at the same time. The first one is an Intel integrated GPU and the second one is a Nvidia Quadro NVS 450. The integrated should display only laptop LCD screen and the eGPU Nvidia should display 2 DisplayPort external monitors.
xf86-video-nouveau is installed with everything related to Intel GPU and i'm running default kernel 3.12.0-1. i915 and nouveau are added to MODULES inside /etc/mkinitcpio.conf and vmalloc=512MB added to Grub command line.
Firstly I followed instructions from here : http://superuser.com/questions/117239/h … k-on-linux
Now here I am, both of them are detected with lspci :
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
08:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 450] (rev a1)
And that should work ! But not at all :-( The computer starts but external monitors (plugged on Nvidia card) stay black/off.
And xrandr doesn't show the second screen :
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 2720, maximum 32767 x 32767
LVDS1 connected 1280x800+0+1920 (normal left inverted right x axis y axis) 261mm x 163mm

I'm using pages 5.2 and feeling completely stupid by not knowing how to link two text pages together. Can anyone help? please...

Hi there, I'm trying to use pages 5.2 for the first time and I cannot find how to connect two consecutive pages together as I use to do with earlier versions of Pages... Any help?

Word Processing templates have what is called a Document Body.
That is the area defined by the margins and holds a default text area which flows from page to page.
Examples of WP templates are the Letters, Reports, CVs etc.
Layout templates have that switched off and require you to add Textboxes or Shapes into which you can type text. Each page is an individual Section and no text flows from page to page.
Examples of Layout templates are the Brochures, Business Cards, Posters, Newsletters etc
In Pages '09 you can manually link Textboxes to flow in your own set order and across pages. Pages 5 has dropped this along with 100 other features.

Is there any way to switch between using two different phones?

I know when phones have SIM cards (like with ATT), you can use two different phones by simply moving the SIM card from one phone to the other and ATT is none the wiser.
Is there any way to do that sort of thing with Verizon?
I currently have an iPhone 5 but would like to start playing around with Android (I'm a gadget nut). So, assuming I find an unlocked Android phone, is there any way to bounce back and forth between using different phones (obviously only one at a time)?

Michael_F wrote:

yes, assuming the phones use the same size SIM card (otherwise, you'll need an adapter or a new SIM card; the cards are free at your local Corporate Verizon store).

Thanks for the reply Russ.
Yes, I've considered adding titles and/or generators in the FCPX storyline, but this creates a need to render the entire timeline. As I'm juggling library locations and hard drive spaces I just didn't want to add a new render that will occupy a lot of space. It's also a bit of visual clultter for me, so my goal is to find the best workflow for adding this stuff on or after export.

Using two bluetooth adapters (not devices) together in OSX?

I was wondering if its possible to allow OSX to use two bluetooth adapters at the same time? In windows, when you plug in two adapters, it places two bluetooth icons in the system tray. It seems when I try this with OSX, the main adapter is used, and the secondary adapter gets listed as a keyboard im guessing, as a window pops up saying it doesnt recognise my keyboard (even though i own no bluetooth keyboards), and it shows up with an improper mac address with the main bluetooth adapter, but not as its own. Is there any way to make OSX notice the second adapter?
EDIT: I guess I should specify my reasoning for this. on windows, because of the way bluetooth works, ps3 controllers need to isolate the bluetooth adapter, rendering a bluetooth adapter solely for the ps3 controller. obviously this works in osx without isolation, but I noticed that since the ps3 controller pairs by mac address, using the same adapter results in only having to pair the controller to osx and windows once, rather than having to pair each time i switched between systems. Also, I would still like to use the second adapter as its own for pairing other devices.

Hi,
Thank for posting in Microsoft TechNet Forum.
Based on my research, two Bluetooth adaptors can work at same time.
In your case, the major problem is the dongle can’t start. I suggest you could test if the new Bluetooth adapter could work in another computer?
Meanwhile, the Code 10 error pertains mainly to hardware and device driver issues or to compatibility issues between hardware drivers and additional software
that is installed in Windows. Therefore, we recommend that you troubleshoot these issues by focusing on device drivers, on device configuration issues, and on hardware compatibility issues.
I recommend you could refer to:
Description of Code 10-related errors that Device Manager generates in Windows-based computers
Hope it helps.

Hi,
I am using two models with diffrent diffrent jcos for that. Is there any problem in that ?
Regards,
Gurprit Bhatia

Hi,
JCOs are made per system (R3).
If your two models are calling two different R3 system then it is fine. But if both of your models are pointing to the same R3 system then you should have only one JCO.
This will improve the performance as JCO connections are pooled in the application server and re-used.

For each iPhone...
From the Summary tab select: Sync only checked songs and videos.
Under Options in the Summary tab select: Sync with this iPhone over Wi-Fi
If you want you can select: Manually manage music and videos.
Select the music you want synced from your iTunes library, same with Contacts.

Using two backplanes together

Hi, can I use to backplanes together using just a Controller cFP-2020 or, if I wish use these two backplanes I'll need to use two Controllers cFP-2020?

cFP can only support 8 cards, so if you have an 8 slot backplane there is no point in getting another.
If you have a 4 slot backplane, you can try searching this site to see if NI has some sort of extension cable, but I doubt that.
In the future, you should post such questions to the Fieldpoint board, because you will be more likely to get an answer.
