DAC8568: DAC80508EVM software installation problems on Win'10 64 bit.

Part Number: DAC8568

Hi, (Paul)

I've received USB2ANY and DAC80508EVM. Thanks.

It is not possible to run EVM software due to NI RunTime engine installation problems.

I've tried NI RunTime package versions (32&64bit) from 2014 to 2019. No effects.

After installation NI soft the message is always as in attached file.

I use Win'10 64 bit.

Regards

Andrzej

  • Hi Andrzej,

    Thank you for your query. Does the USB driver get detected in Device Manager?

    Hi Uttam
    Yes it is detected and also green LED on USB2ANY is ON.

    Hi Andrzej,

    I am glad you received the EVM. 

    We have seen this issue before.  Please uninstall the DAC80508EVM software and any runtime engines still on the PC, then install the labview runtime engine 2015 SP1 64-bit.  When you install the RTE, make sure you launch the installer with the "Run as administrator" option. 

    https://www.ni.com/en-us/support/downloads/software-products/download.labview.html#301182

    Then, reinstall the DAC80508EVM software.  Make sure you install it with the "run as administrator" as well.

    Can you let me know if that works?

    Thanks,

    Paul

    Hi Paul

    Thanks for your help / answer.

    No success.

    I've removed entire old packages and DAC80508EVM soft.

    Then I've installed: 2015 SP1 64bit NI RTE, restart, installation of DAC80508EVM soft as Admin, restart

    and finally the error message is the same as above.

    USB driver is installed (HID type user defined device I think).

    Regards

    Andrzej

    Hi Paul

    The first, NI RTE 2014 32 bit should be installed because DAC..EVM soft is in 32 bit version.

    After that software hangs-on the following screen (see file).

    I think you should know this screen, no solution has been proposed to this moment.

    I've spent many hours for nothing, but my time is a very valuable as well. 

    Regards

    Hi Paul

    Below is Help text for people who purchased totally fatal and not checked DAC80508EVM board and have Win'10 64 bit in use.

    1) Do NOT install LabView NI RTE 2015 or another.    Only LabView NI RTE 32 bit 2014 is OK and should be installed.

    2) Next please install DA80508EVM soft as described by TI.

    3) The third  - please disable Windows Defender Antivirus from  Windows Security as follows:

       a. Select Virus & threat protection

       b. Under the "Virus & threat protection settings" section, click the Manage settings option.

       c. Turn off the "Real-time protection" toggle switch.

    Solution mentioned above help me and DAC80508EVM board is working now.

    But it is NOT GOOD solution.

    Windows Defender should be always active !

    I do not know what information and actions done by DAC80508EVM soft is blocked by Windows Defender ! 

    This is important question to TI but not only one.

    Regards

    Andrzej

    Hi Andrzej,

    1. Your point about the RTE is correct.  Initially, we elected to not include the RTE in the installer to reduce its file size (including the RTE makes the installer >200MB), but seeing the frustration this has caused has led us to question that decision.  I am pushing to get installer for this software recompiled to include the RTE, though that will take a few weeks to get it through sign-offs.

    2. If Windows Defender is blocking the startup of the software, then I suspect it is in regard to the network port the software uses to interact with the RTE.  Most LabVIEW software uses a network address to allow multiple threads to communicate.  I recommend you add an exception to Windows Defender.  If it is the firewall settings, please open network port 3363 and 3364, which are commonly used for LabVIEW software.

    I have marked your post as the solution so it will be easier for future users to find it.

    When you get a chance to evaluate the analog performance of the device please post another thread with any questions.

    Thanks,

    Paul

    Hi Paul

    I've unblocked/open I/O ports UDP and TCP No. 3363-3364.

    It did not help at all.

    Maybe the ports numbers are not correct or them type (TCP, UDP ?) or the problem is OTHER.

    Please note that if I disconnect PC from network the DAC80508EVM program is working OK too  if I previously switched off Virus protection.

    As you see the network and ports blocking state is not relevant for "Loading.vi..." error.

    Maybe in the future I'll have some questions to you regarding DAC80508.

    The example is - how to connect external reference voltage to this DAC since its output is as default also configured as output?

    In DAC8568 chip the internal reference was disabled by default.

    Regards

    Andrzej

    Hi Andrzej,

    The network port is not really to access the web or anything, but the port is used to allow process threads to communicate with each other.  If you add an exception for the software exe in Windows Defender, can you still run the software with Defender enabled? 

    In regards to the reference, we anticipated the case where the user wants to use an external reference.  The reference current capability is fairly low (±5mA), so during startup, the internal reference and your external reference will conflict with each other but only with this low current.  The DAC will either sink or source current depending on the voltage of the external reference. As long as the abs max table is not being violated, there will not be any damage.  This conflicted state will exist until the reference is disabled.

    Thanks,

    Paul

    Hi Paul

    Adding exception of DAC80508EVM.EXE program do Windows Defender is doing nothing. It is not good solution of our problem.

    I've tried some other solutions. No success at the moment.  But I think at this time it isn't so important. 

    Only turning off the "Real-time protection" toggle switch in "Virus & threat protection settings" section helps.

    In regards to the reference. It is very strange and unusual solution to connect output to output 

    especially given the fact that external source of reference voltage is unknown

    e.g. it may be very strong output of OPA or super precision/delicate/expensive external reference voltage source.

    Best regards

    Andrzej
