Slow data transfer during the reading of the GPIB (Horiba CCD 3000) device

Hello to everyone.

I'm trying to connect with a CCD camera (CCD 3000 - company Horiba (formerly Jobin Yvon)))

The connection is made on the GPIB (PCI)

The CCD device is old enough and will not support orders GPIB standard (p. ex. * IDN?)

The problem I have is that after I take a picture, when I want to read data from the CCD

It takes about 10 seconds before arrived it all the data to the computer

the delay is proportional to the size of array of pixels:

When I take the data of the entire area of the CCD (1024 * 256 pixel * 16 bits = 512kB)

It takes 10 seconds

When I consider 4 x 4 pixels 1 pixel (this is done by the hardware) (256 * 64 pixels * 16 bits = 32 k) it taks about one second

What can be the cause of this kind of problem

How can I solve it?

Thank you

As you say, the camera is quite old.  Maybe 50 kB/s is the maximum data rate (probably very 56 Kbps).

  • How much data transfer during the thin VMFS copy to NFS, which does not support thin?

    1. I copy using - VMFS volume thin for a 2003 hosted server NFS volume.  However, there is no indication that the destination in charge it is thin, and the size of the file becomes the size declared.  When I copy the NFS share that does not support thin volume VMFS does, the file becomes thin.

    a. when I copy volume VMFS volume NFS, the amount of data actually traverses the network?

    2. I have two identical servers with the same 5.1 ESXi on them.  When I copy one of them, starts immediately to 0% and charges while the other starts immediately to 10% and progressive count.  I have never seen this on another server.  If anyone has seen anything like this before?

    Thank you!

  • Update ATML report header with the data collected during the execution of the test?

  • Slow data transfer between computer and HP Laser Jet 1320n

    I recently bought a laptop with windows 8.1 and successfully connected to 1320n times via LAN and wireless networks. Problem is when I try to print .pdf files, data transfer from my computer to the printer seems very slow and that's why it takes several minutes to print 10 pages. On the print window of my system, it tells me the data to transfer a file from pdf page 14 are about 75 MB.

    My questions are:

  • Sudden slow data transfer

    Hello

    I am happily using my 3 GB Time Capsule for the last 18 months with no problems. I use it almost exclusively as data storage for my Plex server. I use it wirelessly to my Macbook Pro 2014, in the same room.

    Yesterday, without change to explain it, it has become very slow to transfer files to it.

    I am at a loss, as most of the solutions I looked for people who have had problems of speed from the beginning, mine was a sudden appearance.

    Speeds do not seem to affect my streaming quality that I can still watch a 1080 p 5 gb + video file without stuttering or offset. The problem is isolated to the data transfer it seems.

    Any suggestions where to start?

    I use it almost exclusively as data storage for my Plex server. I use it wirelessly to my Macbook Pro 2014, in the same room.

    The plex server is connected by ethernet?

    Speeds do not seem to affect my streaming quality that I can still watch a 1080 p 5 gb + video file without stuttering or offset.

    It would be difficult to know if streaming is more... and more through your Macbook wireless...

    So I just need to know what is connected by ethernet and what is connected by wireless.

    Wireless is seriously affected by a number of things. So I guess that the first test is to connect the laptop to the TC by ethernet and make sure that it works very well. If your ethernet Mac buy a crush on ethernet card... a necessity, in my humble OPINION... as trying to fix wireless more wireless resembles sawing off the branch that which you are sitting.

    If you can determine the network of the question... Then we can do the simple things...

    Run the diagnostics wireless...

    Just restart the entire network, which I am assuming that you tried but did not mention.

    Simultaneous copy of a file on the hard drive while also streaming can also be stressing the TC... If the tests should be carried out without any other use of disk passes.

  • The data transfer between the processor host RIo for PC

    I have two tables of data that I need to send to the sound card so I can listen to. Data on the processor of Rio. I realize I can write a file wav or something else, but I need the data streaming in. I can do this easily on the single PC of course, read and write to the card sound (or ADC/DAC etc.), but on the processor of rio, there is no card sound for obvious reasons and so I need to transfer data from a level to the PC. What is the best way to do it?

    More information, these data were acquired of a RIo FPGA and transferred via FIFO for Rio processor.

    Hello

    There are several available network protocols to transfer data from your target in real time to the pc. This article covers the pros and cons of those commonly used with LabVIEW Real-time.

    For dissemination of data tables between LabVIEW screws (one on the RIO, one on the host computer), I recommend the network stream if you use LabVIEW 2010 or later.

  • Envy 14: HP Envy running very hot (slows down periodically during the video)

    Hello

    I would like to get information on how to properly clean my HP Envy 14 laptop fans, number of product B4B14UA #ABA. I tried to use boxes of air through the ventilation openings, but I'm able to accomplish turns too fast the fans. I'm unable to remove dust. It is a laptop I've owned for about 2 years.

    I suspect that the fans/vents are blocked because the winds blow warm air and the base of the laptop is almost too painful to sit on my legs. The upper part of the keyboard runs hot along the strip of aluminum above the function keys.

    Although the use of the battery for several hours, now it takes an hour, running minimum settings due to the heat. In addition, while playing video, the computer will freeze and cause the video to stutter occasionally. I tried a computer laptop cooling pad, but it doesn't seem to be the problem.

    So, in summary, I would like to know whether or not to clean my laptop fans would void its warranty (if it still exists) and whether or not fans of cleaning would be possible for a layman.

    Thank you for your time.

  • Slow data transfer between PC and Agilent N3300A

    Hello

    I use a N3300A of Agilent connected via Serial-> USB to a PC running LabVIEW 2012.

    In my tests, I found that the time required to recover data from is very long. The example below, supplied with the drivers, I measured each of the subVIs 3 who read the instant action takes about 11.7 seconds to complete.

    Therefore, this example VI does not work out of the box, I need to increase the maximum time constant and to also connect the two subVIs away. In otherwise, a time-out occurs, the device no longer and needs a reboot to be controlled by the PC (have not found another more elegant way to get the control).

    Is it possible to speed up the process of data recovery? And as a bonus question, how to control remotely again the instrument after a timeout place?

    Thank you for your time

    What is the data format?  Instruments can usually transfer using ASCII or binary.  Binary would be more effective.

    GPIB would fill a lot faster (can reach 1 Mbps).  At 9600 baud, you run 1200 b/s, excluding the start and the stop bits.

    Assuming that the binary format to 4 bytes/data point, your serial communication should take about 3.3 seconds.  Assuming ASCII with 12 bytes/data point (pure guessing here), which is 10 seconds.  11 seconds for a transfer is therefore not out of the question.

  • Slow data transfer for USB flash drives

    When I transfer a file to a USB flash drive, the transfer is very slow. I checked my USB host controllers and they work very well. There seems not to be of hardware problems. Here is the Dell gx270s, the two XP Professional SP3 running computers. I didn't find any solution on the support site for anyone. Controllers are Intel. I used the Driver Max and it does no problem - but I wonder about the accuracy of this program.

    Anyone who has ever had this problem and figured it out?

    1. What is the brand and the model number of the flash player?
    2 is this problem limited to this flash drive?
    3 are. what transfer speed you now?
     
    Check if the transfer rate is the same on another computer. Also, try using a player different flsah on this computer and compare the transfer rate. I would ask you to update the drivers for the chipset on the Dell site.
     
    I hope this helps.
