• Sort channels

  Hello

  I now have the names of channel group:

  Max Freq offset

  FREQ Drift

  FREQ drift rate

  Offset1 Max Freq

  FREQ Drift1

  FREQ naturel2 drift

  And when I use the script sort Channel:

  C:\Program FILES (X 86) \NATIONAL INSTRUMENTS\DIADEM 2014\Examples\documents\SortChannelGroups.vbs

  He is not sort her properly.

  But if I rename the names of test instead of the rate of drift in Freq DriftRate Freq then it works properly.

  Concerning

  Hi René

  Sorting is correct, because it uses the code ASCII of a white (32) is smaller then the ASCII code of '1' (49). I fear that you will you rename (temporary?) groups. You can add a blank space in front of the number or replace white by another character.

  You can use this little feature to replace the temporary vacuum and add the call at the beginning and the end of the script:

  Void RenameGroups (sSearch, sReplace)
  
    Dim oChnGroup
  
    For each oChnGroup in Data.Root.ChannelGroups
  
      oChnGroup.Name = Replace (oChnGroup.Name, sSearch, sReplace)
  
    Next
  
  End Sub
  
  

  
  

  If Data.Root.ChannelGroups.Count > 0 then
  
    Dim oGroups
  
    Call RenameGroups ("§","" ")
  
    Set oGroups = Data.Root.ChannelGroups
  
  Dim saGroupName()
  
    ReDim saGroupName (oGroups.Count)
  Dim iLoop
  
    iLoop = 1 to oGroups.Count
  
      saGroupName (iLoop) = oGroups (iLoop). Name
  
    next
  call QuickSort (saGroupName)
  If oGroups.Count > 100 then call MsgBoxDisp ("Kanalgruppen werden farblich...", 1 ")
  iLoop = 1 to oGroups.Count
  
      Call Data .move (oGroups (saGroupName (iLoop)), oGroups, iLoop)
  
    next
  Call RenameGroups ("§","" ")
  
    call MsgBoxCancel
  
  end if

  I hope this helps!

• Remove or replace (NOT append) data channels PDM

  Is there a way to delete the channel that has already been written to a TDMS file data?

  Simply write the tot data new data channels appears to add the new to the old.

  I don't see a way to remove OR replace the old with the new dat.

• TOSHIBA 32AV933G loses control of channel list

  Hi, I bought this TV 3 months ago and I have a problem with SORTING CHANNEL function.

  After reorganization channel as a result of my personal list (I use the same order with all my TV) the av933g has lost the order without apparent reason, forcing me to reorganize all the channels every time.

  The order is usually 4 to 5 days before scramble

  I installed the latest firmware but the rest of the problem

  Hello

  In my opinion, you should contact Toshiba service to verify your TV.
  As much as I know there not many options that could enhance or fix this problem.
  You can try to reset the TV and could update the firmware, but it's what you could do. Everything must be done by the technician.

• Some USB flash drives REFUSE to work in this 40TL963B

  Hi all. I recently bought a new 40TL963B and so far I have found nothing wrong with her.

  Except that... when I listen to it all the Satellite channels, I noticed thay were very different from my FreeSat box. Duplicate the layers, randomly arrested... etc. It made me want to not use the built-in satellite feature.

  However, I found a program called ToshibaEdit which allowed me to manually change all the digital channels on the TV. Grand... I though. Until I met this problem-->

  Inorder to change the ads, you must copy the TV channels on a USB flash drive, you can edit them on your PC. Now, it took me AN HOUR to do, because of two flash readers I used, none of them worked... I kept getting a "Write Fail" error. WTF?

  The disks are formatted in FAT32, one is a 8 GB is 2 GB.

  Finally, I tried an external 2.5 "USB 120 GB hard drive. Even if the disc is defective... This WORKER. I expect flash drives to work, to be honest, but all of them... the external USB hard drive worked.

  In any case, I spent another hour sort channels, until I was ready to transfer the data back. And. Yes... the same problem. This time, I received an error "failed to read". Again, tried the external USB HDD... worked the first time.

  Now, this HARD drive is faulty, so he'll be thrown... so I'm going to need a flash player to do it again if something happens.

  And then... can ANYONE tell me why on Earth two appropriate, fully working almost brand new USB flash drives REFUSE to work in this TV, but a former, fairly well defective USB external drive MADE? In addition, the same flash drive that I tried to copy the data from digital channel with was also used for a backup of the Firmware... and it WORKED perfectly. It works also for use with the media player.

  While this TV has a hatred of Flash drives all of a sudden?
  Anyone can shed some light on this?

  In addition, very quickly, TV seems to lose its TV settings every time that I bring the TV out of Eve. I'm going to the TV Dynamic and adjust all the settings, but he returned to AutoView and all settings back to 0. Is it a fault or is there something I need to do to 'save' the settings per channel?

  Any help at all will be appreciated greatly.

  Hello

  > And then... can ANYONE tell me why on Earth two appropriate, fully working almost brand new USB flash drives REFUSE to work in this TV, but a former, fairly well defective USB external drive MADE?

  AFAIK the 40TL963B TV supports a common HS USB 2.0 interface and memory flash can be formatted in FAT16 or FAT32 file system. So there is no specific requirement for USB flash memory

• Sort the channels in Toshiba 47L7453DG

  Hello

  I recently bought a new Toshiba 47L7453DG TV and I tried to sort the channels, but it was impossible. I found in the user manual, the following note:

  "Renumber, move, sort, and delete functions are not available for the antenna channels. Renumber, move, sort, and delete functions are only available for the DVB - C in Germany. »

  However, as I read in other posts, Toshiba recommends the use of this software (version 1.04) ToshibaEdit.

  I followed the steps described below:

  1. I transferred the list of channels of TV on USB
  2. I have compressed files
  3. I opened the in ToshibaEdit
  4. I reorganized the channels
  5. I saved the zip file
  6. I unzipped the files to USB
  7. I transferred files from USB to TV

  So far so good. However, although the list of channels is changed, the TV shows 'No signal' message across all channels, and I have to re - set my TV or load the original files that were exported from the TV (the first time).

  Have you already tested ToshibaEdit L74 series? I saw a similar post somewhere on this forum and a user had the same problem, but you have not proposed a solution. What seems to be the problem after you have saved the files in ToshibaEdit? I followed all the steps exactly as described in the manual here, hereand here.

  Please for more help I've been banging my head for 3 days now and I can't find a way to sort the list of channels, which BTW, is a very basic feature for all TVs.

  PS. I upgraded TV for the last firware (T8_1_97_09_01_1).

  Best regards

  Recovery of the subject.
  I have the same problem on the same model.

  Maybe somebody has already invented how to sort strings?

• Toshiba 32EL933 - DVB - T channel list is not sorted in hotel mode

  Hello

  I have over 100 of these TVs, and I have problem with hotel mode.

  I use USB drive and one TV (find paths and creating a new list of channels sorted, with my order), and then I use usb for programming other TV sets. And I have no problems with that...

  But after a few hours/days, my list of created channel becomes not sorted. Without reason. I all schedule them again! We use the DVB - T signal. Poland in the country. And this problem does not appear on the 3 other TVs (not TOSHIBA)

  Help, please

  Sorry for my bad English

  Hello

  I read in a different thread that the activation of the option + "Control Panel lock" + menu would solve the problem with the chains unsorted.

  Not sure if this would help you but it s worth a try.

• Channel import from time to tiara from a PDM file

  I have a generated Labview tdms data file has the timestamp clock computer written in the file as a string. When I add this tdms file to the portal in DIAdem data it is important this time string channel, and I can't trace this as the x-axis data. I would like to import this time string of the tdms as a weather channel file easily. Is this possible?

  The work around I have found is to import the tdms file in excel, and then save as an excel file. I can then import this channel since the Excel using the Excel Import Wizard and specifying the time stamp column is a weather channel. Surely, there must be a better way.

  Thank you.

  Hi PRinOR,

  Here is a VBScript script that converts each text string "Time Stamp" in the data portal to a 'Time Stamp' datetime string.  You can run this VBScript manually whenever you load one of these TDMS files in the data portal, or we could implement to run automatically on your computer as an event of BROWSER loading custom.

  If you can convince the controller LV for a Brown wire entry datetime to the PDM file, then this new channel of data will appear as a column of values datetime correctly recognized in Excel, even if the display in Excel will be different from the datetime string in your TDMS file because Excel does not this default format (I think it's possible with a custom display Excel datetime type) display type.

• Read specific channels of an existing PDM file

  Dear users of Lab View,

  I would like to ask for help using the PDM read Vi to read specific channels in existing TDMS files.  I know to use the "contents of list TDMS" vi to that group names and channel list, but I don't know how then use this information to read identified specific channels.

  the problem, I'm trying to work around is to read a file of PDM with data from two channels, each with a different amount of data taken at different speeds. I would like to read a block of data from a single channel.  However, this data block contains more elements than the other channel. So, end of file error almost everytime I meet because the read PDM Vi tries to read this block of data for each channel.

  How can I specify the channel for the PDM read VI?  I tried to create a constant and fix them on the node "channel name" on the PDM read VI, but it gave an error.  I guess I don't know how to format.

  is attached the VI I'm trying to implement

  A sample file is too large to attach.

  Thanks for the tips

  I think that the problem may be that you close the TDMS of origin reference in each iteration of the loop, try to move outside as shown in the snippet.

  Note that I don't really went through the logic for the rest of your code.

  

• Channels of naming when writing to PDM

  I am acquiring several data acquisition systems data and write it in a PDM file. My goal is to have names for each channel that will appear as a header for the data in the PDM file, but I also want to allow the user to change the names of channel if he wishes.

  The question I have is this:

  I wire a control in port TMDS "channel names. It gives me a table I can input names of channel in... well.

  The problem is I want to be able to save these channels for when I close the VI, but also whether they are adjustable upon request. I know that to be able to do what I have to select the Option "use selected default values. Lets say I made the names of channel, T0, T1, T2... etc., once I selected the "Make selected by default" all channel names, I wrote are now default to T0 (IE, T0 T0 T0 T0), not, T0 T1 T2 etc...

  How can I make sure that the default straings to T0, T1, T2, etc and not T0 T0 T0.

  Thank you for your help and your time.

• PDM - reading of a single channel

  

  I taste ten channels AI DAQmx and write to a file of PDM using "DAQmx Configure Logging (PDM) .vi" with 'logging mode' value 'Log '.

  Each channel has 1.8 seconds of data that has been sampled at 1 MHz.

  I later analysis data of each channel (one at a time) but it wants to optimize my code for the effectiveness of memory, since I sometimes come against the dreaded error "out of memory".

  Ideally, I'd like to be able to specify only the channel I want to read, but using the ".vi DAQmx Configure Logging (PDM)" does not tell me the names of channel.

  Can I use the express vi to read, but all the data comes out and I need to select which channel to retrieve dynamic data. What I do not know if it is dynamic data already effective memory or is there another method I can use?

  If I use the 'PDM open file' followed by 'PDM read' years use 'index array' can I have one channel too but all channels read puts all data in memory at the same time when I want to only read one channel.

  When you playback of PDM, you can specify which group (s) and or channels to read from.  You can first use a PDM read properties for a list of the groups and channels and then browse the list of strings for the treatment both.

• PDM-file: how to set the description of the channel?

  Hello

  I use the "DAQmx Configure Logging.vi" to capture the raw data from the measurements of May. Which works very well.

  

  At the end, after the acquisition of fiishing, I want to save the PDM. To do this, I want to add some properties to the PDM file. Using "TDMS Set Properties.vi" works, but ot for all properties. I'm able to add the name, description, title, author and date/time (yellow cells in the screenshot). How ca I add the description of the channel (see green cells in the screenshot).

  

  My real simple code to change the properties of PDM:

  

  Thanks for your help.

  Better subject.

  Michael

  If you want to write a property for the channel, you must provide a group and a channel for the service to know which channel the property goes with.  If a group is provided but no channels, it assumes that the properties for the group.  If neither are provided, it assumes that the file.

  Oh, and you should go give this idea a Kudos: Additional metadata TDMS
