  I have problem to find the code example. So far, I can only build a counter edge without a controller trigger like below. Could someone help me?

  

  
  

• Multichannel relaxing break

  Hello world

  I am a beginner with LabView. I'm able to acquire several analog signal of my PCI 6221 using DAQ Assistant, but my requirement is to measure only all my entries with relaxing break for example I need to acquire data only when my example PFI10 is Hawaii. Whenever the PFI10 is Lo, the break of the measure.

  I found an example to reach the break here. However, it is only for 1 channel unfortunately. I do not understand about the flow, but I tried several times to add another channel to my purchase, but without success. Maybe my knowledge is limited and only able to start the project of the DAQ Assistant, but not this type of project.

  I tried to add another channel to DAQmx create Virtual Channel.vi but he couldn't accept two inputs. Maybe I need some kind of multiplexer?

  If the question above can be done, how do I add another measure DAQx Read.vi inside the while loop?

  Can someone tell me how to add channels (I need at least another 2 analog channels) on this vi? I think, any other user who are in the early phase like me will all benefit your respons.

  Sincere greetings,

  Hague

  Hello

  Found the solution (vi attached). But it is only from 2 channels.

  Kind regards

• DAQmx how to control the level of tension AO paused for a relaxing break?

  I have an application where I need to generate a waveform of a fixed frequency (~ 200 kHz) and the amplitude, but for differing them burst lengths and different lengths of time between bursts. These bursts and these delays are controlled by a line of DIO to generate the relaxing break. I also need to have the output voltage analog voltage controlled between bursts of waveform. I explored using various trigger options, the break seems to be the best solution, but I'm difficult to control the particular point of the end of the waveform during the break occurs to make sure that the break is at the same specific voltage when the wave is hidden. I try to adjust the position of the example 'Analog output Pause for the periodic Signal with regeneration on specimen' but cannot get regular tension during the break I'm after. I use a card Series DAQ. X is there a simple way to pre-set the tension that will be broadcast during the paused state when using a relaxing break? I was not able to find it in the examples or documents. I can't use the code of reference AO set example because it is a software-driven and does not fit into the model of schedule I need to generate.

  Hello

  I don't think there is a way to establish a certain level on the analog output, based on a relaxing break.  I watch using a redeclenchables task analog output and do every hour of beginning to the required voltage.

• Sync to external trigger in conjunction with a nearest pulse frequency device fixed...

  I am writing an application running a scan frame. One axis of the scanner runs at a fixed frequency. I use a scanner high speed 5105 to get the data. The slow axis of the scanner is controlled by a servo with an analog input. I have will probably use an M-series card for analog control, but can also go with a 6713 (output only) or another Board. Fixed frequency Analyzer provides a clock line, I want to use to drive the 5105. In addition, the analog card must be synchronized in this. The entire system should be able to accept a trigger external devices, as it starts scanning at the edge of clock on next line.

  I'm not quite sure about what would be the best way to do it. External triggering from other devices will be an indeterminate pulse width, so I can not just use it as a portal for the line clock. I am reluctant to do it in software (IE via the detection of changes on a digital line) because I want to be reliable started the next clock pulse. I have taken into account things like a counter/timer with a relaxing break, but which could lead to drift between the narcotics control and frequency scanner fixed. It seems just more complex that I think it should be, and it feels like I'm missing a simple way to do it.

  Any suggestions?

  Hi cshl,.

  Good to know - the 5105 has a duty cycle of tolerance of 45-55% (mentioned on the page of the form), so that is why you cannot change clock speed from 3 to 12 MHz on-the-fly (though if you make small incremental updates over time, it would be theoretically possible).

  With the additional information in mind, you might want to try the following on the 5105:

  Use the external trigger as a trigger of departure (arm of acquisition).

  Use the line as a signal reference clock (with a position of 0 samples for reference ~ 7500 are after initiation).

  The problem with this is that you will have to re - trigger on each line - 5105 has a 2.4 rearm us time (also mentioned in the page on record).  If this is unacceptable, another way that I can think of is to use a clock to external reference in PLL internal clocks of the bezel to.  If you can provide a stable, a clock accuracy 50 ppm which is synchronized with your scanner within reach, would solve the problem of drift over time without having to re - trigger on each line (only acquire data continuously).  This clock frequency must be between 1 MHz and 20 MHz in steps of 1 MHz.

  We have no Council can take in an external variable clock up to 12 MHz (on-the-fly), but if you wanted to compromise a little bit the 6115 can enjoy up to 10 MHz, and has no obligation to cycle to 45-55% so it's maybe interesting look in.

  As far as AO goes, I assumed that the clock line is declared after the quick scanner has completed his turnaround (ideally you do not update the zone of OCCUPATION during the lead time).  If you have a signal Analyzer that you can use instead probably easier.  If not, our peripheral series M and X series (but not the series AO 67xx) offer reference clock feature so if you go with the idea of reference mentioned above clock it may be easier to simply PLL the clocks together.  These cards in a PXI chassis or are they PCI form factor?

  I don't know what you mean by the sticking point about the need for two triggers.  I think the idea is that we use the external trigger to arm the 5105 and clock line to trigger each record.  However, if you do not need to generate a pulse double based on the clock of your line then you can use counters to do (our counters are redeclenchables with time to rearm in the ns range).

• In v31.0, I can view is more 'raw' XML files with line breaks and ' < ' and ' / > ' characters. Is there a setting that will give me this option?

  Until a few days ago when I opened a file XML with Firefox, I see the content of the file appears with line breaks and ' < ' and ' / > ' and elements. Like this:

  fixed image in < typeOfResource > < / typeOfResource >

   <genre authority="marcgt">picture</genre>
   <genre authority="nmc">Print, Photographic</genre>
   <originInfo>
     <dateIssued encoding="marc">1884</dateIssued>
     <dateIssued encoding="marc">1884</dateIssued>
     <issuance>monographic</issuance>
   </originInfo>
   <language>
  

  Now, it will display like this:

   still image picture Print, Photographic 1884 1884 monographic eng electronic
  

  No tags or line breaks. I need to see the entire XML file. How can I configure FireFox to display this for me? One of my colleagues uses v31.0 and XML views with tags and the line breaks for him.

  For example, I was looking at files sitemap.xml (search Google for inurl:sitemap.xml). For those who have not declared a style sheet, you should always see the classic "source highlight: presentation

  Example: http://www.website.com/sitemap.xml

  Are the files that don't appear as similar planned by not declaring a style sheet?

  As a temporary workaround, you can view the source to see the original. Either:

  • CTRL + u
  • Right click > view Page Source

• Redeclenchee HW with line Enable Pulse Train

  I am using the 'Multi-multifunction-Ctr Retrigg Train generation of impulses for the Clock.vi sample' in the Finder for example LabVIEW to sample a waveform. It worked great, but now I need to sync my purchase with another piece of equipment. The material defines a "Enable" high TTL line when it is ready to acquire and I need to start my purchase at the pulse of available next synchronization. The option "Activate" is low and I have to stop acquiring after than the gust / the current image is complete. I tried to use a line of 'Pause' and a 'Digital Plan' trigger but doesn't seem to work with a finite pulse train. Since it kinda is diffficult to explain in the text, I have attached a waveform.

  Any suggestions? I use an inLabVIEW DAQPad 6016 8.5.

  I would treat differently the digital. If you watch the digital parallel and just read single points, then you will have a quick way to signal to the loop to HAVE the enable option has been low. I added an untested VI which should give you the idea. There is probably a better way to manage stopping both loops, I just did a quick and dirty method. After watching your VI it dawned on me that you could build a machine of the State where he's just looking for available samples then actually starts reading, and once there are no samples available after a certain period of time you would stop. You would still need the door AND but would not need to worry monitors the enable line. This would be probably as fast that monitors the line to activate it if.

  For a door AND every door TTL AND must accept a 5 V power supply. If I remember just a 74LS08 should work - if you only need the one you may be able to get a free sample.

  see you soon,

• As a router WRT54GS cascading with IP fixed address block

  Hello

  I read several threads on the routers in cascade and the Knowledge Base, but none seems to fix my script with a router with fixed IP address block.

  My current setup is an ADSL circuit with a block of 8 fixed IP addresses. Of them the first xx.xx.xx.137 is assigned to interface the router, the second xx.xx.xx.138 for the router itself WAN xx.xx.xx.139/140/141/142/143 leaving as usable IP addresses. Connected to the ADSL circuit is that a D-Link DSL-G604T router with NAT disabled to allow IP addresses to be assigned to my web servers and ftp. Of course, DHCP is disabled on the LAN interface.

  Unfortunately, the transmitter wireless on this router is defective so I would my Linksys WRT54GS (Firmware v1.50.6) D-Link router cascade so that I can use it (with active DHCP) as a point of access for multiple wireless devices.

  This thought through to logically I've named WAN 54GS with one of the xx.xx.xx.140 to static IP address available, a subnet mask 255.255.255.248 and the door entry xx.xx.xx.138. I left the LAN settings like the beach 192.168.1.xxx and DHCP active. I then connected the interface WAN of the 54GS to one of the LAN connections on the D-Link with a straight ethernet cable.

  I can connect to the admin 54GS via a direct ethernet connection and wireless interface but not to the internet.

  I can ping that is the xx.xx.xx.140 of the interface wan of the 54GS since a laptop computer connected wireless but not the IP address of the gateway of the network xx.xx.xx.138. D-Link router.

  Am I missing some other settings in the router. Especially in the routing section advanced? I guess that the device must be set to a router rather than the bridge, but if there are parameters of dynamic routing?

  Any help would be appreciated

  Thanks Brickmonkey,

  Just thought I would update this post. I tried from you suggestions, but to no avail. The frustration I did a hard reset of the router D-Link and set it up again from scratch and... Hey presto it now works.

  I can only think that there may have been some settings left from when the router has been initially implemented for Nat and I had configured port forwarding. In any case it now works OK then thank you very much for your answer.

• Muse CSS output with line breaks?

  Is it possible to go back to the way Adobe Muse written CSS in how it used to, with line breaks and not one long stream?

  I use Muse to build quickly to the HTML and elements CSS that I take in a custom CMS that I built for my client basically build, modify and maintains its Web site. It works really well, but now I've upgraded to a newer version of Muse the CSS seems to appear as a constant stream no line breaks. I guess this is to draw down the size of the file, but it is extremely difficult to isolate and alter some elements. Y at - it an option to export the CSS with line breaks?

  {{I could use a search and replace in a code editor to replace the} to} \n, but I like Adobe Media and it doesn't support \n apparently.

• Button - ranging from relaxing break time

  Captivate 8.0.1.242 - Windows 7 64 bit - format swf

  
  

  I add a button that runs a term action advanced exactly like this post (CP8 - add a replay on a slide button for). I have a 1 minute video CPVC. Now, I want this to exist always replay button, but not pause the slide. I have other buttons on the slide that takes care of pause before dragging the output. But this BACK button comes with a break. Anyway, like any other button, I'm trying to move the break in the timeline using the mouse slip and fall at the end of the timeline around 59 seconds. But whenever I drag beyond the current view threshold line time including 17 seconds when captivate is maxed out, the break dates back to about 3 or 4 seconds in the timeline panel. It's so weird. I don't even need this break and if I try at least to go beyond the length of the video, I am facing this problem.

  

  CP8 stupid Newbie UI! The suspension and the duration are more in the properties panel, but in this Panel of timing:

  

  I never use the Newbie UI where everything is controlled by CP (I don't like be). Maybe you will see it in the docking station right when you select the button? Or he must go to the window menu, and then select properties for synchronization?

  Suzi,

  I changed the code for page 1:
  I don't know that is what you want, but it works :)
  That's what I did

  1. deleted tags
  2 P1_RESULTS element created to keep results
  3. $x_Value ("P1_RESULTS", myNewString) occasion; to fill a new element

  You cannot set the value P1_S2I in dynamic Action (onchange) - it looks like the code calls herself and kills the browser

• binary file with line break

  Hello

  Today, I need to import data from a binary file / mixed text. The structure is

  CH1 octet1 Ch1 Ch2 Ch2 octet2 CrLf octet1 octet2

  CH1 octet1 Ch1 Ch2 Ch2 octet2 CrLf octet1 octet2

  CH1 octet1 Ch1 Ch2 Ch2 octet2 CrLf octet1 octet2

  My first attempt was a DataPluginExample3.VBS updated the

  Void ReadStore (File)

  Sun block: SetBlock = File.GetBinaryBlock)

  Dim Channel1: Set channel 1 = Block.Channels.Add ("Low-Timer", eU16)

  Canal2 Dim: Set Canal2 = Block.Channels.Add ("High-Timer", Ue16)

  Dim canal3: Canal3 Set = Block.Channels.Add ("CrLf", Ue16)

  Dim ChannelGroup: Set ChannelGroup = Root.Channelgroups.Add ("ESR_Timing")

  ChannelGroup.Channels.AddDirectAccessChannel (Channel1)

  ChannelGroup.Channels.AddDirectAccessChannel (Channel2)

  ChannelGroup.Channels.AddDirectAccessChannel (Channel3)
  "(Kanal 3 ist nur $OD$ OA CrLf)"

  End Sub

  Unfortunately, each odd sample, the data are corrupted and then become misaligned. And the beginning of data entry does not exactly start a new line.

  So I would use the CrLF to re-sync.

  How can I mix the approach of the ASCII-readline with binary data?

  The following does not work: I try to tell the trainer to use vbNewLine (= CrLf = $0D $0) to separate lines and use the channels of direct access with the data type of U16. But when you use the line break, apparently the import filter also expects the delimiters instead of raw binary values.

  Void ReadStore (File)

  File.Formatter.LineFeeds = vbNewLine

  File.SkipLine () ' Sicherstellen, dass erste wird ignoriert line unvollstandige

  Sun block: SetBlock = File.GetStringBlock()

  Dim Channel1: Set channel 1 = Block.Channels.Add ("Low-Timer", eU16)

  ' Dim canal3: canal3 Set = Block.Channels.Add ("CrLf", Ue16)

  Dim ChannelGroup: Set ChannelGroup = Root.Channelgroups.Add ("ESR_Timing")

  ChannelGroup.Channels.AddDirectAccessChannel (Channel1)

  ChannelGroup.Channels.AddDirectAccessChannel (Channel2)

  End Sub

  Thank you for your comments.

  Hi Michael,

  I think this use made the rounds.  I had to ignore all partial to the first row of values in order to keep the correspondence of the line of the high and low timer values.  Also note that by default the U16s are read with LittleEndian byte order - you can change that with File.Formatter.ByteOrder = eBigEndian.
