• How do troubleshoot you a USB virtual COM port?

  Object

  Send orders of Labview to an Arduino board using the Advanced Serial write and Read.VI.

  The problem is that no orders are received by the Arduino.

  However, I can use the Serial Monitor built into the Arduino IDE to send commands to the Arduino and get the required result.

  I checked baud rate, the designation of COM port and the command is a simple as string 600,0.  The VI shows no error message.

  So, I'm looking for suggestions on how to troubleshoot a USB virtual COM port.

• How can I connect the HOST PC COM port under cRIO 9074?

  I can't find any HOST PC COM port on my cRIO.

  I tried to use the global variable, but it was useless.  Is there a solution?

  And why should he?  A cRIO is really another computer.  You expect your PC to see serial ports to another PC on your network?  No, you wouldn't.

  If you really want the cRIO again the serial port of the PC communication, then you will have to apply on the PC that can communicate with the cRIO, usually over TCP/IP or network stream.

• How can I create a simple virtual machine with the CD in a newWorkflow

  I created a new workflow with simple virtual machine and added a cdrom workflow but an error is shown.

  How can I reuse of so that the new created VM add a new cdrom in a workflow

  

  Help me please

  First of all, you only need a single attribute of type VC:VirtualMachine, not two as in the screenshot. You don't need to specify its value; When the first workflow completes, its output should be attributed to this attribute, and then the assigned value must be passed as input to the second workflow.

  To check/edit links, open the first workflow to change, go to the 'Visual links' tab and make sure the workflow output is line connected to the attribute. Do the same for the second workflow, and then make sure that the attribute is connected to the line to the corresponding input parameter.

  Take a look at the workflow attached if you don't know how the maps should look like.

• USB/Virtual COM port Communication problem with ESP301/LabWindows/CVI

  Hi all

  I have gone through different threads posted in this forum for similar issues and all tried, but nothing helped.

  I'm trying to communicate to the ESP 301 training monitor via a USB port configured as a serial COM port using a CR. Have it ' command is to get the version of the controller. The "write" "ComWrt" command works fine but the read command throws and error ("-99 operation e/s timed out"). I tried all the suggessions; with delays etc... who has explained (resolved by Mr. RobertoBozzolo) in the thread posted here, which explains an issue similar to that of the mine, but the help couln t.

  The code is attached.

  I am using 2012 LabWindows/Windows7 64 bit multi-hearts

  int Get_Version () {}

  comport = 3;

  BaudRate = 9600;

  parity = 0;

  DataBits = 8;

  error = GetRS232ErrorString (status); Error message "e/s timed Opération" out

  return the situation;

  }

  Can anyone suggest where I am doing wrong?

  Thanking you in advance.

  Another thing you should check is baud rate.  The ESP301 by USB is expected than the baud rate to 921600.  The function for OpenComConfig() group implies that it does not support this baud rate setting, but it seems to work perfectly.

• How to access a host USB Virtual Serial Port from a VM Application?

  I have a Linux VM running under VMware Player 5.0.2 on a Linux host machine.   I have a development system running on the computer, virtual trying to download the code on an external device connected via a virtual serial port USB host (ttyACM0).   Anyone doing programming Arduino device will be familiar with my software/hardware config.  Dev VM system does not directly hear the ttyACM0 port I need to establish some sort of connection bridge between "ttyACM0" host port and the port of VM-configured "ttySx"?   Someone did something like this with a VM Player?

  FYI, I found the answer to my own question in an old post on a similar topic. Here's a response provided by the user 'Worker' in the former post office that was the solution to my problem.  I followed its general approach and mounted my own virtual *.vmx machine configuration file to change the serial port set of ' / dev/ttyS1 "to" / dev/ttyACM0 ' I can now download code on my device directly from the Arduino IDE running on the guest VM system.

  Worker (1 positions since November 23, 2010) November 23, 2010 12:56 am (in response to AnthonySowden)

  A bit of an old thread here, but I wanted to say that I was able to do exactly this yesterday using VMware Server 2.

  It wasn't easy, but I managed to hack in there.  I guess that this trick works also on VM WS but I have not yet tested.

  Here are the steps:

  Start your VM turned off.

  Add a serial port of your virtual machine through the normal interface. -J' I just let it use/dev/ttyS0.

  Go to your virtual machine folder and edit the .vmx config file.

  Find the line:

  Serial0.filename = ' / dev/ttyS0 ".

  Replace:

  Serial0.filename = "/ dev/ttyUSB0 '.

  and off you go.  The guest operating system sees it as a real physical serial port and is fortunately out my system through series console!

  Hope that helps other people.

• How to create a Virtual Com Port in Windows 7 for Palm HotSync

  I've just updated wo Windows 7 Pro 64 bit.  Because Palm does not support USB synchronization under a 64-bit system, it tells me that I need to create a virtual com port for my bluetooth device to synchronize.  I can't understand how to create this port under Windows 7.

  Hi Sonmox,

  Welcome to the Microsoft Answers site!

  In the Sub in view of the link you need to download the Palm Desktop and HotSync Manager. This software allows you to synchronize your device Palm with your computer, for your info is backed up and easily editable on your computer.

  Visit the following is given link of Palm and configure your Bluetooth device.

  http://KB.Palm.com/wps/portal/KB/common/article/49229_en.html

  When you set up your Palm device to synchronize using Bluetooth technology, you create a 'Bluetooth partnership' between your devices your computer (also known as "pair" or "trusted device"). This allows you to synchronize your device wireless and your computer have to authenticate each other, every time that you synchronize.

  Follow the steps in the document to sync your Bluetooth device.

  Hope this information is useful.

• How can I create more space in my virtual memory

  How can I create more space in my virtual memory

  In fact this post with this link is pretty bad.

  Virtual memory used by xp as ram memory, however the memory or

  swap file is on the hard drive. For a pc of refrence memory from a hard drive is very slow

• How can I get my USB printer doesn't work?

  I am trying to install a Dell 3000cn laser printer in my computer. He started by putting a virtual printer in my control panel that would not print it had nothing on the Hardware tab, under its properties and real hardware was still on the list of unknown devices in the bottom.  I removed both and removed the driver and tried to install the printer before I plugged it in which does the same thing as before so I went into the Device Manager and there was no printer listed. I've uninstalled the usb printer support and removed everything that are associated and tried. Now I get support of usb error has a printer driver problem.

  I tried to support the customer of Dell they got hung up, I tried Windows customer, they want me to pay.
  I've exhausted the research online and can't find 5 people with the same question online all back in 2008 to 2010 which was never resolved.

  How can I get the USB printer to work?

  Generally, printers do not appear in Device Manager.  You will see, however, registrations for "IEEE 1284.4 devices ' or ' IEEE 1284.4 compatible printer" in particular for HP printers.  It is possible that your Dell printer is really a re-badged HP.

  What exactly did you delete when you have uninstalled the "usb printer support '?

  Please provide the full error message text that you do when this error.

  Why do you think you had a 'virtual' printer is installed?

  Click Start, click devices and printers.  What are the items in the category 'printers and faxes '?

  Did you download the driver appropriate for your version of Windows (including 32-bit or 64 - bit) from here--> http://www.dell.com/support/home/us/en/04/product-support/product/dell-3000cn/drivers?

  Did you follow these installation instructions:

• How can I create nested VMware ESXi in vCloud 5.5

  Hello

  I how can I create a VM ESXi nested within vCloud 5.5.

  I followed the instructions below, but it does not appear as an OS selected in the database, it creates only an option, but the drop-down list displays the 'other' os.

  http://basraayman.com/2012/03/01/enabling-nested-64-bit-virtual-hosts-on-vCloud-Director-1-5-using-MSSQL/

  Kind regards!

  I just stumbled upon this problem sort of.  I had it working in 5.1 vcloud, but upgrading to vcloud 5.5 caused all sorts of havoc.

  Looks like vCloud 5.5 added a drop down for the esx hosts in the family of the 'other', but it does not appear when you create a virtual machine, you must create it with some other reviews and then change the properties of the vm created for select esx guest.

  If you have added the SQL statements from this link, it will completely break vCloud because there will be two entries in the database for esx and he complain of a unique key.  You must change the database and remove what you added in the link above.  The tables are guest_os_type and guest_osfamily.

  Good luck!

• How can I create a new presentation of shop e-commerce in British Colombia? The default layout is inadmissible and who do not steal! :)

  Hello to everyone.

  I've been building and development using BC for awhile but avoids the functions of e-commerce like the plague, because of all my knowledge and trial a mistake, I couldn't adjust available outside the columns of the table how much I can add. I'm looking to create some sensitive stores but feel completely constrained by the store layout because it can't be adjusted. Yes I tried the same and adjustment module style sheet styles declare my rules with "!" important"with no luck. I then asked the team to BC online chat. If it was still possible, and they said 'no' dish. Then I saw 'light at the end of a tunnel' If you want by browsing a few Business Catalyst models (I honestly can't bring myself to use models that I like a lot of this building and landscaping my own pages). With this model here, the cameras and accessories you can see the shop features sensitive so I know it's possible (Damn you BCGurus and your mad skills). I also found some amazing layouts by Enough of Pollution , which has also made a few sensitive shop like this Web sitelayouts.

  Overall, how can I achieve this? How can I create a fully customized store page layout and virtually any custom also available? I have the feeling that I needed to learn the programming language for this liquid, but seriously, the indications at this point would be greatly appreciated! If I learn liquid programming, I'd love to learn where there might be some amazing courses / tutorials / documentation. I have the feeling, it comes down to create my own model of liquid layout and rerouting of the off-set modules in the new model... I'm on the right track?

  Sorry, so many questions. Let me tackle that I really want to know haha!

  
  
  

  • How can I create a layout of the sensitive shop in British Colombia?
  • What would be the necessary steps?
  • If I need to build models of liquids, where can I learn all this? (I know that the BC user guide has much butI will not lie, it's a little overwhelming)

  Thank you all so much for your time in reading this and I greatly look forward to learn more about Business Catalyst. Honestly, I'd love to try and use this platform for all of my clients.

  Hello

  Support will be have not said you that it was not possible, they would have told that it is outside the scope of their support. Is this possible? Of course, it's, it's the foundations of basic BC, HTML and CSS more then anything else.

  Honestly, it has nothing to do with incredible skill, amazing code or anything else.

  First of all, BC is just tags and you should use reference material:
  The developer reference

  Here you see the overall plan and tags. If you look at the list of product tags you see that you can set in a list schema (no tables).

  From there allows you to encode your small layout, large presentation cart layout, provision of registration (payment) because you need to and code the CSS to adapt.

  -You can float elements so float the li of the store

  -The basics of the CSS to make the elements of fluid width of code etc.

  -Questions from the media CSS code to make sensitive matters

  All pretty much toast front-end html, css, nothing special here development stuff. You have classes on the points for each element of a line in British Colombia according to the parameters that you set on the tags and so on.

  If you want to take the next step you enable liquid markup in the characteristics of BC and take things further.

  Hi LaserShore,

  Think you that you added the 64-bit platform settings target according to this page? : http://zone.ni.com/reference/en-XX/help/372636F-01/mstudiowebhelp/html/64bitcore/

  Already running 32-bit application? Have you changed references to the 64-bit version?

  You use Measurement Studio? If so some features are not supported with 64 bit.

  Also when you say that you have added the NIDAQmx.lib, did you follow this KB:http://digital.ni.com/public.nsf/allkb/38F67B28D995C6958625706E000C580C
