• Choose the network protocol for CRIO-9024 to PXI on Ethernet

  We are in the design phase, implementation of an embedded controller for CRIO-9024 to send data captured at an SMU-8105 on ethernet controller. The data will be arrays of double-precision 2D. These data should be sent to the pxi at the end of each test step. Each stage will have a different number of channels and sampling frequencies.

  For example, Test step 1 will have 5 channels of analog inputs that will be sampled to 100,000 KHz for 1 second. These data will come from the CRIO FPGA. Data will be get dealt with by the CRIO-9024 and analyzed post to pass or not not metric. Then, the CRIO controller will send the data 2D (data points 500 000 5 X 100 000) table and the results of all the measures (a table 1 d) for PXI.

  The connection with the PXI will use Ethernet.

  Do not forget that the PXI should also send the CRIO certain values to tell the CRIO when starting the test, and when the test sequence is completed.

  I thought that TCP/IP would work better because of communication 2-way necessary. But then I was watching streaming network or even using shared Variables.

  If anyone has any ideas or suggestions please please post them.

  Hello

  You can use either.  If you are more comfortable with really.  The STM method will be a little less overhead on my style XML tagging data, but it will be very short given the size of the data.  Probably go with STM has it right most of the work for you.

  Regarding the size data the you must normally transfer data as this is to flatten to a string.  If you convert a string of numbers readable human you will either lose accuracy, increase the size or both.  Because the string after that flattened will be the same size as the original array anyway for the quick calculation based on your previous post 500 000 double (8-byte) is 4 miB (3.8 MB)

• DASYLab Lite, CompactDAQ Ethernet, "the stream blocked by a later module" error

  I receive the message 'the stream blocked by a later module' and then the execution stops. I tried to remove the modules without change. He usually stops 8 minutes, 20 seconds (500) in the race. It happened on two different computers (same network, however). How can I get my program to run longer (forever?)?

  I am using a cDAQ NI 9188 (CompactDAQ Ethernet chassis), NI 9237 (strain gauge module), NI 9211 (thermocouple module), OR-DAQmx 9.5.1 and DASYLab Lite 12.00.01. My program of DASYLab affect strips from 100 Hz sampling frequency. The calculation of the average (reduce) block performs an average arithmetic with the size of the interval of 100 and a block size of output of 1.

  

  Thank you!

  Which module complains about being blocked? Look at the title bar of the message - it should show the name.

  You can observe the locking by turning on pre-trial block view-Animation-FIFO.

  I am suspicious that average organizes blocks more were awarded.

  One thing to try and really monitor your computer after doing this...

  Go to the Options menu in the spreadsheet view, then open the General preferences. Change these two settings - see the image - turning them off. The risk is that your application uses too much memory, so, please, provide oversight.

• HP m8120n no Ethernet in the Device Manager and not detected

  Hey all:

  I have a desktop HP Pavilion Media Center m8120n (product sheet here) and I recently did an installion of installation clean factory, Windows 7 Pro 64 bit with a DVD retail of Windows. I managed to get the drivers for almost everything, but there are some persistent problems.

  The most serious of them is Ethernet. I can't find drivers ethernet for this machine, even after the update of Windows running several times, no hardware drivers have been found. The ethernet controller/port is not still appear in Device Manager at all!

  I tried to use the driver for this calculation pager on the HP support site, but there is no mention of all the Ethernet/LAN drivers at all.

  I read that sometimes it is important to update the chipset first driver in order to get the job of ethernet. Since HP provides no chipset driver, I decided to try updating the chipset 8120n with theutility to update Intel drivers Intel's Support page.  I have updated to version 9.4.0.1017, once the Web page has scanned my system. However, even after the update the chipset and Windows restarts, I have still no Ethernet at all.

  Depending on the product specifications page, under the section network, the computer uses a controller Ethernet Intel 82566DC. However, after trying to install the driver for the Intel 82566DC since the Intel, the installer website told me that no network controller Intel were present on the system.

  What is really worrying, is that not only does the Device Manager does not even see an Ethernet controller, but the Intel drivers update utility didn't recognize it under the section "Wired" after that the latter had analyzed my computer. Ethernet controller also does not appear under system information.

  I'm starting to wonder if it is a hardware issue and not a driver problem at all! The Ethernet port may be damaged or does not work for Windows do not install the drivers, or even recognize it.

  Does anyone have advice or steps I could take to rule the hardware problem and find a driver that works for my installation of Windows 7 on this computer?

  "Violence is the last refuge of the incompetent." -Issac Asimov, from its roman Foundation.

  Good new! It worked! It was really the BIOS that was causing the problem.

  On the Advanced Settings tab, there is an entry called Onboard LAN off, just like the desktop I have to work!

  After booting, Windows installed the drivers for it right away, and now I get to enjoy this sweet Gigabit speed on my network!

  I'm so happy that it was not a hardware problem, and that it was a simple change to the configuration of the BIOS.

  Thanks for all your help!

• Image sequence Ethernet to check the value 0 x 00000000

  I see intermittently frames ARP (requests and responses) equipped with a FCS set to all zeros.

  On one VLAN, ~ 300 000 ARP frames in an ~ hour, including 1100 ~ contained an FCS all zeros.  Occasional inspection suggests that only Windows VMs produce these odd ARPs.

  I have seen this all first capturing using Wireshark loaded on a virtual Windows machine.  However, the trace that I reference here was taken using a Fluke Optiview XG (one of its Ports 'network', i.e. material custom able capture rate).

  Seems to me that any frame with a FCS of all zeros will be abandoned by receiving guests ("bad FCS").

  We are short of vSphere 4.0.0 build 385281

  Here is a screenshot of such a framework.

  

  For a trace, see https://Vishnu.FHCRC.org/bad-FCS/

  I'm trying to understand how to capture images (not only ARPs) containing a FCS set to 0x0000, to see how widespread is this issue.

  Looking for the communities 'Frame Check Sequence' site, I didn't know all the signs that correspond to this

  Suggestions for other search strings?  Someone at - he seen already?

  I don't think this is really a FCS of 0, but instead Wireshark bed trailer all 0 of the framework of the FSC.  The first thing to check is if the capture actually includes the FCS. According to the http://www.wireshark.org/faq.html#q7.10 most of the BONES are not. support capturing the FCS.

  The second thing is to take a look at your preferences of Wireshark. In the menu, select Edit-> preferences, expand the Protocols section, scroll down to Ethernet and check the setting of the packets is suppose to have FCS. If this box is checked, Wireshark will do exactly as it says for example, assumes that the package has a FCS and will give you the FCS incorrect error message you see.

  This isn't an inverse logarithm, it is one logarithm using any other basis as the existing buttons for base 10 or base 2 logarithms.  The "y" is any basis you want to use for the logarithm.

• After the upgrade to USB 3 Hub Ethernet Sierra is no longer works

  On my mid-2015 15 "MBP, I have a Sitecom CN - 340 USB 3 Docking station. Apart from all kinds of outputs, it has an Ethernet port, which I've been using for the last 6 months without any problems... until the update for Sierra. Since then, the report of control center that the cable is not connected. I am now connected via Thunderbolt. Has anyone noticed this too? And then knows how to fix? The latest drivers are February 2016.

  Kind regards

  Oliver Holmes

  It turns out that the problem is so the driver being old-fashioned. The chipset is the AX88179 and the manufacturer provides its own drivers here: http://www.asix.com.tw/download.php?sub=driverdetail & PItemID = 131

  So, all is well again.

  Ethernet USB adapter does not work after update to mac sierra.

  Please solve this problem as soon as POSSIBLE

  Hello guatamshah,

  If your USB to ethernet adapter does not work now that you have upgraded to Mac OS Sierra, there are a number of things we can try to get it working again.

  The first thing we want to do is to reset the SMC and the NVRAM on your Mac.

• Leave my Calculator only recording not in the latest issue

  I have been using the calculator that comes with OS X to keep my checkbook balanced for a few years. In general/system preferences, I don't have not 'Close them windows when you exit an application' checked. This should I want to open the calculator with the last number still saved. He has in the past, but since the upgrade to Mac os Sierra, calculator saves what I had (except on the Strip). Is there something I can do to recover this feature?

  I can check your results even if I do not remember if she previously recorded the last number. I don't know if it's a change of function or a bug etc, but I think it's something Apple should change. You could install PCalc for the App Store. It is not free, but it does a lot more.

• Ethernet to the airport also on?

  I have my Mac connected directly to our home Airport Extreme via an ethernet cable. That same Airport Extreme acts as our main wifi router. Until recently, I didn't cause to turn on the wifi of the handiest airport on my Mac, but I have to if I want to use the new Sierra "unlock with Apple Watch" and copy and paste between the characteristics of devices, that which I want to be able to use.

  My question is, is my default Mac using the connection of the cable as my internet source or have two internet connections active will complicate things?  Is there a way to prevent the Mac to use the wifi for the internet, but still have it on for the other features it offers?

  Thank you.

  Nevermind, I found the answer outside this area communities:

  http://www.Macworld.com/article/3039842/Macs/can-you-use-Wi-Fi-and-Ethernet-on-a - mac-to-the-same-SystemRoot\Cluster\Reports\Validation

  You can dictate the order of preference for which network source is used in settings > network on your Mac. By moving "Ethernet" upward, your Mac always uses the Ethernet Wifi or any other sources listed below, as long as the Ethernet is an active connection. If something happen with your Ethernet connection (cable comes off, maybe) your default settings for Mac to the next source in the list that has an active connection.

  Apparently there is nothing wrong with having active ethernet and wifi connections at the same time.

• Ethernet questions

  So I don't know what is happening but I had an internet outage the other day for about 36 hours when some construction cut my ISP ADSL line and never feel things acted like weird, but from what I can tell it's my 4th gen time capsule at fault.

  Only 1 of the 3 ethernet ports seems to put on the internet. I use the other to my basement, and it sometimes says it's on the right of the network with no internet access, but most of the time just says unidentified network, no internet access. He worked all day but seems to just decide he doesn't want to chance.

  The other problem is that the TC itself appears to be loss of connection randomly with flashing orange. When reset, it works again. Don't know what is happening here. I use a PPPOE set up to connect via the TC; the ADSL modem is connected via Ethernet. Nothing has changed on my end, this could be a service provider because of the failure?

  Thank you

  Also, the modem is a router?

  What is the make and model?

  I use it as a router and try again with just the bridge the TC.

  PPPOE can be problematic.

  Ethernet ports can blow... If you get a tip to the top of the line... then we can take any ethernet port connected to both... If that includes the Port of the TC WAN no longer functions as a router.

  You have a little work to understand the question... but another router is key.

• Unable to connect to the internet using Ethernet

  I have a Mac mini as I try to connect via Ethernet cable to a modem Comcast Arris TG862. I was connected via Wifi without problem (with the exception of the slower speeds). I know that the Ethernet ports on the back of the modem seem to work, since I can listen to my TV, etc. In settings > network Ethernet shows as green and connected and gives me an IP address, but as soon as I turn off Wifi no web page doesn't load.

  What I am doing wrong? I thought that it would just connect. On the Ethernet port lights, which I think means data transfer. Otherwise, I need to tell Firefox or Chrome to turn to the Ethernet connection?

  Thank you!

  The default configuration is to have the WiFi over Ethernet in the Service order.

  The order must be set such that the (desired) primary service is at the top of the list and the backup service is below.

  If you look at the order of service when it is connected to the network, the higher is the provision of access Internet one (or at least, he thinks Yes).

  To set the order, click on the menu of the machine and choose the order of Service. Move Ethernet to the top of the list. This should make it primary unless he loses the connection.

  However, it must move up Ethernet and provide a connection when you have turned off the WiFi. When you disable WiFi on the Mac, the Ethernet connection move to the top of the list and show a green connection?
