• Difference between FFT LabVIEW and Matlab FFT

  Anyone know why there is a lag in the absolute levels of the results of the function in LabVIEW and Matlab FFT?

  See the VI attached for an example of my code to LV.

  Also attached is the plot generated in Matlab, which seems to be compensated by ~ 37dB.

  This was generated by using the command "plot (10 * log10 (abs (fft (x))))", where x is the same as in the VI input array.

  Thank you very much

  Dan

  I see you are using the VI of spectrum FFT which returns a unique range of face.  To convert a transformation both sides (IE FFT) in one spectrum sided with RMS units there is a standardization of sqrt (2) / n, where N is the number of points in x (t).  You can prémultiplier your x (t) by N/sqrt (2) and get the same results as Matlab.  Or, you can use the FFT.vi so you compare transform to transform instead of spectrum to transform.

• Communication between HP eprint and Google Cloud Print

  Hello

  communication between HP eprint and Google Cloud Print seems to be broken. At least for me.

  Documents to print when I print vio Chrome browser or Cloud Print dashboard - but the State in the clouds print remains "submitted". It seems that somehow the HP eprint status doen't get referred to cloud print. In HP eprintcenter paper says "printed".

  Well, I wonder who will take care of this problem...  (Hope this does not lead to fingerpointing only...)

  Thanks for your support!

  Best,

  Started more work, a few weeks ago. All is well now. Don't know who that sets well.

• The interface of LabVIEW and matlab

  Hello, I want to interface LabVIEW with MATLAB using the TCP/IP protocol for data transfer. Can anyone, please give me an instruction step by step how to do this? If not, can point out you where I can get them? Thank you.

  Hi Gilles,.

  TCP/IP is a generic protocol then you should easily be able to build enough interfaces TCP/IP for your LabVIEW and Matlab code and data transfer on ASCII or variants, etc., depending on what kind of data you are trying to transfer. I'm not too familiar with Matlab, but on the end of LabVIEW, there are a few examples of server and client very good TCP/IP provided with LabVIEW.

  Another option you may want to, and the reason why I answer it is that I did recently a project through which we took some legacy code MATLAB which we wanted to transpose into LabVIEW, so that we can automate then completely a test system that we use TestStand. A big part of it, we have been able to derive equivalent LabVIEW, but some functions where LabVIEW does not have an equivalent appropriate, or where it was simply more effective, simply copy us and paste Matlab code in any event in the first instance MathScript nodes (not dependant on Matlab) or Matlab script nodes (which will return if all goes well at a later date to transpose in full) LabVIEW for that is no longer dependent on a Matlab license).

  In both cases, the facility to do this was very impressive, and we were able to wrap huge amounts of code Matlab LabVIEW with very few problems. As an idea, have you considered your functionality of Matlab of packaging in this way and keeping all the customer TCP/IP and comms server in LabVIEW?

  Note: If you have not found it pick up the palette "Matlab Script.

  Good luck

• Encrypted L3 Communications between the TOWER and WLC?

  Hi all

  I work with a client who wants to put the towers away to their WLC (a 4402). The problem is that communications between the TOWER and WLC must be secured, even through their private Wan! I have a few questions that result, if someone is able to help you;

  1. I can't know if and what method of encryption is (is it AES etc.?) used on connections between towers and the WLC and what are the steps?
     1. The terminology can be a problem here, it's not a wireless mesh, just classic LAP for WLC
  2. EXTENSIVE customer network is already encrypted (IPSec VPN via VPLS) in parts - what is the consequence of execution of AP<-->WLC with end to end (if possible) on a network encryption EXTENDED with IPSec, i.e. double encryption?

  Strange but true - pointers will be greatly appreciated... Phil.C

  With a controller of the 4400 series, the control traffic between the AP and the regulator is already encrypted AES.  The user traffic is not encrypted.  If you use a 5508 controller all traffic between the AP and the controller is encrypted AES.

  For what is running the traffic through a VPN, it should work.  The issue I see with this is with the MTU in general.  The controller will drop all packets with a payload of less than 32bytes data.  According to the MTU over the VPN I've seen packets getting fragmented and it is a question.  If you use one of the versions CAPWAP (5.2 or newer) discovery dynamic MTU is part of the Protocol and this MTU problem does not really exist.

• Disable communication between the host and the virtual machine

  I have VM Server 2.0 and one of the virtual machines has the same name as the server and even if the virtual computer is connected to the host only network it generates the Windows error message: duplicate names exist on the network.

  is there a way to disable communication between the host and the virtual machines? I just need a virtual network that is isolated from my network complete and host also.

  Thank you.

  The GUI Server2 is not to choose the other unused vmnets.  Then edit your file VMX use a different vmnet of 0, 1 or 8.  (which are bridged, host-only and NAT)

  Thus, for example, if your VMX has a line that says:

  Ethernet0.VNET = "VMNet0.

  change to:

  Ethernet0.VNET = "VMNet2.

  (This assumes that you have not used the network Editor to fill the vmnet2 either).

• communication between master blocking and blocking fowarding sensor sensor

  1. how the communication between the master sensor blocking and blocking fowarding sensor take place?

  RDEP or SSL or SSH? Which one?

  Forwarding of blocking sensors will use RDEP more 443 (https) to communicate with the master blocking sensor.

  To ensure that the sensor of blocking of the Master to allow connections from sensors transfer blocking under the hosts permitted configuration section.

  Here's a link for how to do this with VEI:

• 2012 of LabVIEW and MATLAB use

  Hello.

  I am using the Matlab data plugin (http://zone.ni.com/devzone/cda/epd/p/id/4178) with LabVIEW 2012. I installed the plugin and the installer says that the installation was successful. However, the plugin does not appear in the list of plugins in LabVIEW. I rebooted the system, but that did not help.

  Data plugins are incompatible with LabVIEW 2012? I also tried to add the plugin using the vi of the data plugin manage the palette. Although the vi does not return an error, the plugin still isn't available. Decommissioning of 2010 is not an option for me, because I need some of the new features.

  Thanks for your help.

• How to set up communication between Netgear DG834 and Equium M50?

  Can't get Netgear and portable to commmunicate wireless, the amount of the fine if I use the cable between them or fine if I installed the driver for the unit provided with the Netgear Wireless USB plugin. But the wireless card built-in to do not or cannot see the netgear router? Anyone has any idea why

  Hello

  Perhaps is the card not activated correctly? Check the status in the device under network adapters Manager. If everything is ok check FN + F8 key connection and select Wi - Fi is the ACTIVE option.

  After that, you should be able to see WLAN network if the router works well.

• 2012 LabVIEW and Matlab script server error

  I just installed LV 2012 and upgrade the code that runs Matlab scripts. Now when I run it, it gives me an error of server script (1047). I'm using Matlab 2007. Someone at - it the same problem? Anyone know of a solution?

  I guess it has to do with the server script does not properly. But I can't exactly run the same code in LV 2011 without problem while LV 2012 gives me an error. Same computer, etc.

  Thanks in advance for any help you might be able to provide.

  Thank you "transfererror", this helped me identify workaround.

  For those who struggle with this, that's what I learned:

  1. This affects only the variables that are passed in a sub - VI in the connector pane (that is, local variables are not connected to the connector pane apparently do not have this problem).

  2. it seems to only affect as vectors 1 d or 2D paintings. The reason why the screws inserted by Sev_K example applies to this problem is that the types of data that are not arrays do not have this problem.

  3. Thus, to solve my problem, I inserted just an addition of 0 to all vectors and matrices that have been passed in the Sub - VI. I guess what it doesn't copy the variable in a local buffer and it is perhaps the reason why he fix it?

  In any case, workaround seems to work. I don't know what it costs in terms of speed or memory, but I do not have much about it for my application (some real-time applications that use Matlab scripts eventually consider it).

  Perhaps this information can help identify and fix this bug.

• communications between IPSec VPN and AnyConnect SSLVPN

  Hi all

  I have 2 ASAs and interconnected with ipsec VPN.

  one of the ASA has SSLVPN users to access intranet resources.

  but do not know how to get inside the network on an another ASA

  my network architecture is less to:

  192.168.1.0/24---ASA1---Internet---ASA2---172.24.0.0/16

  SSLVPN use 192.168.55.0/24 ip on the external interface

  L2L IPSec VPN is established between ASA1 and ASA2

  192.168.1.x could access 172.24.0.0/16 via NATing to of ASA2 inside the ip interface

  But now I want 192.168.55.0/24 access 172.24.0.0/16, some set up but does not work...

  Are there any suggestions?

  Thank you very much

  Hi the split tunnel, you add with the ASA2 network should allow vpn clients send the traffic through the tunnel when they want to reach the remote subnet.

  Can add you this too

  nonat_outside ip access list allow

  NAT (outside) 0-list of access nonat_outside

  Also in the config you have not added the crypto to ASA1 acl entry. who is 192.168.55.0 to 172.24.0.0

  See if that helps
