• Sony ILÇE-7R - what is the speed of read/write in the camera

  I have several Sony ILÇE-7R cameras used for a given application where more than 80 panes in a row with 1 second interval occur.

  When you are taking pictures on a 1 sec shutter time / 1.2 s, then the camera tends to slow when writing the buffer on the SD card. (A suitable high-speed sdcard has been used).  When the buffer is disabled on the SD card, then the camera accepts no any command of the shutter (IR Led or cable gives the same question), so I'm missing components/images.

  What is the read/write speed in the camera?

  What are the compensation of buffer time?

  Are there settings that can improve the buffer time on the SD card, while taking still pictures of compensation?

  Is there firmware settings that have been implemented to improve the write speed camera?

  Thank you very much

  Kind regards

  
  

• How do you know the speed of read/write of a flash drive?

  Who knows a program to read/write speed?

  Hi Cristi,

  Thanks for posting in the Microsoft Community.

  An indication of the standard flash drives read/write speeds is the following:

  USB 2.0:

  Sequential write speed range = 4-10 MB/S

  Sequential read speed range = 15 to 25 MB/S

  USB 3.0:

  Sequential write speed range = upto20 MB/S

  Sequential read speed range = upto45 MB/S

  These reading and writing speeds offer a guide to the read/write Flash Drive performance and have been identified in recent tests. Please note that we are changing the components USB Flash Drive at any time based on the availability and cost. This means that the read/write speeds above cannot be guaranteed.

  You can use your favorite search engine to search for this application that measures the speed of read/write of flash drives.

  Warning: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

• What's wrong is the reading speed of my HARD drive?

  I have two HARD drives identical, which is bought in the same month, when I check the State of health, both work very well.

  referring to the next image, the speed of execution on top of the HARD drive is very slow.
  Someone has suggestions on what evil possible, it could be?

  Any help will be greatly appreciated :>

• NFC tags low level read/write operations

  Hello
  
  I know it's little bit offtopic question - but since you are experts in the field I will try you may ask a simple question:
  
  1 / I want to know what protocol is used to read/write for the NFC operations, tags are used. According to my understanding after that the label is placed on the NFC (NFC, USB drive phone) reader, it is powered and set to the ready state. The application protocol for read-write operation is used. As I think that the format and content of the commands used to read/write is not specified in the ISO 14443 and it is based on a material/manufacturer and will be different for FeliCa, Mifare, Innovision, etc tags, so there is no way how to handle read/write NFC tags with unique implementation operations. This hypothesis is correct?
  
  2 / are there tags, that supports the 4 7816 APDU commands for read/write operations?
  
  
  Thanks for the reply
  Kind regards

  Hello

  To read the NFC forum specifications. It will be better explained than by me.

  several protocols are used according to the contactless front-end configuration and capabilities. It includes ISO14443-A, ISO14443-B and Felica. Sometimes the other protocols are also available, for example Innovatron (not Innovision lol)

  Mifare is not a Protocol, it is a line of NXP products. These products use the lower layers of the ISO14443-A protocol specification.

  There are 4 types of tags

  (1) using the lower layers of the ISO14443-A
  (2) using the lower layers of the ISO14443-B
  (3) something related to felica?
  don't know exactly on these 3, you should read the specs. Everything is clearly understandable, not like ETSI.

  (4) something using commands ISO7816-4 on top A ISO14443 or B or others. You must SELECT, BINARY, BINARY update READ. You can implement using javacard, I did it and it works. You need two binary files, which can be hard-coded.

• Maximum latency to read/write for PCI-DIO-32HS with NOR-DAQmx?

  I was asked to evaluate using the PCI-DIO-32HS and NOR-DAQmx on MacOS X to essentially close a control loop.  My first concern is whether or not it can run fast enough.

  So my questions are: what is the maximum latency from the moment of receiving a signal strobe reading data from external hardware, then read a single 16-bit sample and sending it upward by NOR-DAQ to a user space application?  And, similarly, what is the maximum latency of sending a unique 16-bit value from a space application user down through NOR-DAQ, then write a port and affirming a strobe signal of external-data writing material?

  Thank you.

  Hi AliasMe,

  Thanks for posting and welcome to the Forums EITHER!

  Do you need to process the data in the software and generate a value on this basis?  DIO-32HS (alias PCI-6533) offers in the buffer of inputs and outputs, but you'd have a latency in your control system relying on the OS to do treatment.  Since this period is dependent on the system, I can't give a specification for the amount of time it would take.  However, integrating data in memory, processing and writing back to the card would likely be on the order of several milliseconds.

  Generally, we recommend FPGA in situations of control like this, so you can do all the processing in hardware.  However, if provide you more details on your request we can look into all the options available.

• I have a memory card reader/writer. You want to know what it takes to put photos on card

  I have a video photo frame that I put my memory card in to see photos. but cannot modify them. so I bought a card reader/writer, I have used before and had no problem. but didn't write what I did. now, I don't know how to recover my pictures on the computer to the memory card.

  If you insert the memory card into the reader and go to...
  Start / computer... you will find one or more removable
  Discs that represent the slots in the card reader.

  For example...

  Removable disk (e :))
  Removable drive (g)
  Removable disk (h :))

  Once you learn which represents removable disk
  the card slot is in you can copy and paste or drag and drop
  photos on the drive letter that you want to copy on the map. If
  you get to pictures in your folder images, you can
  Right-click on a group of photos or a folder and the
  menu choose... Send to / removable disk (? :))...)

  Tip: There is a limited number of files can be copied
  in the memory card root directory. You can see a
  error, something like:

  "Impossible to copy the XXXX: failed to create the directory or file.

  You can avoid this problem by placing the files in folders
  on the map.

• What is the network latency acceptable in milliseconds for users on a WAN to come?

  I heard number as 125ms being a number to shoot for VDI and good user experience, but what is the number of the real world?

  Acceptable latency is the right number until all of your users start to complain that this document, http://www.vmware.com/files/pdf/view/VMware-View-5-PCoIP-Network-Optimization-Guide.pdf, said shoot for less than 250 ms.

• under condition of read/write terminals on the side of the connector (basic training 3)

  Hello

  During my practice towards the review of the CLD, I examine the Core 3 online training material too. I just read a few tips of 'best practices' on the forum, for example this post:

  http://forums.NI.com/T5/LabVIEW/Community-Nugget-wired-terminals-in-subdiagrams-clearing-up-the/m-p/...

  It should be noted, that we should not use terminals (which are on the connector pane) to the inside of while loop or condition of the structure. Neither control, nor indicators (read/write terminals): "terminals conditionally read or written on the side of the connector are BAD!"

  I can find many examples in the online training materials, when the indicators and controls are placed inside while loop and the case of structures in a Subvi.

  I guess I should not do this during my review of the CLD, as they will run benchmark on my project? Should not be the core training materials updated some time? Or it's just not too important to have terminals on the outside? I would lose points during the CLD Exam my project as in the Core 3 screws?

  example 1: Core 3, exercise 4-6 design of an error-handling strategy:

  

  EDIT:

  What's even more ugly in this project, is that, in the case of 'Get empty Cue', the Cue output indicator is updated via a local variable, because the indicator is not accessible via 'outside ': wire

  

  Nice catch on the training material.  that the application would take an if subject to a review of the CLD test graders.

  As noted in the nugget: sentencing of perfomance for conditionally reached terminals is a function of the size of the data.  So, it is sometimes acceptable for simple data.  The larger point being to learn about compromise and make the right choice for your code.

  Preping for the CLD on other means of hand knowing that VI Analyzer will run on your project.  Like any other code review you walk in - know the guidelines for the review and code to ' review ' as well as 'reply spec.'

  I've not seen an instance where an example of shipping (2013 and later versions) would fail this test VIA (there are a few screws deep inside the vi.lib which can date back to before the adoption of this recommendation from style)

• Tecra A8 DVD don't read/write DVD-R 1-16 x.

  Using Sonic Record DLA, Tecra A8 DVD don't read/write DVD-R 1-16 x. Ok work on DVD - R 1-8 x and CD DVD - R 1-16 x has tested successfully on the two recent Toshiba Satellite Pro and HP Office. Have updated the Bios, software DVD-RAM and Sonic DLA.

  Hey,.

  What exactly do you mean? This means that you can t burn DVD-r with 16 x speed?
  In this case, you should check the specifications of your CD/DVD drive. Not all models support this speed of combustion. In addition, I recommend using 8 x only, he speed will give you a better quality of the burned data/average.

  You must also use different types of media. I believe that your other computers have different drives in order to test different mediums. I have a good experience with Verbatim DVD-R.

• DVD recorder is not read/write discs DVD-RAM on Satellite A200-1GH

  Hello!!

  I have the problem as the topic - my DVD drive is not read/write DVD-RAM discs (recorder: HL-DT-ST DVDRAM GSA-T20N). Unfortunately, there is no any drivers (more recent than I've got) for this recorder on the Toshiba, not even site on LG or Microsoft. What should I do?

  Greetings

  Hello

  To be honest, it's quite strange. If the laptop is preinstalled with recovery image, it should work. I tested it on my laptop 5 minutes ago and it works. The DVD-RAM disc is readable and different documents can be saved on the disk too.

  Do you use your own installation of OS, or you still have some factory settings?

• Carpet * a UJ-830 cannot read/write DVDs on Equium L10

  Hi, I have a laptop Equium L10. My DVD RAM mast * a UJ 830 cannot read/write to DVD discs. But it can read and write CDs.
  I have installed the latest driver but no luck. Any suggestion will be appreciated.

  This problem appears since day one?

  I ask because it looks like a hardware malfunction, to me it seems that the lens can not calibrate properly and that's why the drive can read and write DVDs.
  What burning software do you use?
  For the most part a burning like Nero program provides an error message if the burning process failed

• Satellite L500D - can't read/write DVD

  Hello

  About a fortnight ago my DVD drive stopped reading/burning DVD and now only times/burns CD I followed the guides to remove the upper and lower filters and reformatted my laptop to factory State and the DVD player does not work.

  I bought a new replacement drive, and is not reading the DVD either so im assuming that my original DVD player worked but there is something wrong with the hardware of the laptop itself?

  I bought the laptop in November ' 09 so it is still under warranty or is there anything else I can try?

  See you soon

  Hi mitchello,.

  > and reformatted my laptop to the factory of the State and the DVD drive has failed.
  If you have tested with factory settings and it still doesn t work it s hardware malfunction but it strange why s it doesn t work with a new disk

  What program you use to read or write DVDs? I can recommend the VLC to play all the multimedia content and CD Burner XP Media Player like burning program. Both programs are freeware and works perfectly. Never had a problem with these tools.

  Have you bought a new drive to an authorized service? I ask this question because not all readers are compatible with all mobile phones due to the assignment of the different pins. If the new drive does not work you can return it for a replacement.

• Enter a share with read rights and have read/write rights

  I have a folder with my photos on my Mac. In this folder, I have all my photos in subfolders and will add new pictures once I created the share. I want to make them accessible to my family there own PC/Mac. But only with READ ONLY. My problem is that a user (account to share on my Mac) with reading rights can access my shared with read/write rights.

  I have my Mac with 10.11.2 the following users/groups:

  • (Jens) My Admin account
  • (Erika) Account sharing
  • (Family) A group

  Group of members of the family are:

  • Jens
  • Erika

  My folder permissions to "/ Volumes/ExtHD/Bilder" are:

  • Family: read
  • Jens: Read/write
  • everyone: read

  I enabled file sharing in the system settings and the 'Pictures' folder added to the share list.

  Now I go to another Mac with Yosemite, go to network in the Finder, select the computer with the share, connect to the "Erika" and open the folder "pictures". I can generate records or files, delete files, so I have read/write rights. Why?

  Finder don't show me no option 'Erika' should have rights to write to this folder. Why is she able to delete files?

  If get you information on the drive, it is the checkbox ignore verified property?

  What is the format of the disc?
