• How can I programmatically determine if a TCP port is still open

  I use STM to go from communication between a GUI and a reat-time target. Everything works great except if the TCP connection is terminated at each end for a reason any. How I can programitcally queries the port to see if the connection is still valid with on a read or write on the port?

  LabVIEW is not any sort of TCP 'polling' VI. You will need to perform an operation of TCP and get the error provided to indicate that the connection has been lost. What did you do once you have discovered if the connection is no longer valid? Did you want to open a new connection and start using that one? If so, the best way to handle this is by trapping the error conditions in your code. If you get the error "connection interrupted" you open a new connection and try the operation again. I don't know how your code is structured, so I couldn't really tell you the best way to implement this in your code.

• PXI-8431

  A question about the NI PXI-8431/8 serial port card: is it possible to directly control the TX (transmission) & read the RX (receive) state lines?    I need to implement a scheme of communication series using separate data and similar to SPI clock use differential line drivers.

  Looking at the example RS-485 Transceiver Control.vi, I see that it is possible to control the State of the control of serial port, CTS, DCD, DSR and DTR signals, RI and RTS.

  Hello wantacobra,

  You will not be able to directly control TX & RX lines because the PXI-8431 is specially designed for the RS-485/422 Protocol. Pass it and receive lines will be always expected a package of series. Yes, you can directly control the serial port control signals, but not the TX & RX lines. It would probably be best to get a circuit designed for the protocol you want to use.

• half-duplex configuration 9871

  I am trying to configure a NI 9871 4 ports 485 series add-on half-duplex communication with non-echo.  My problem is that I can not understand how to select the transmitter/receiver mode.  Table 3 of the manual (http://www.ni.com/pdf/manuals/372277e.pdf) shows four different modes, but it's a mystery to me how to set the mode.  The module is currently in mode 4-wire where the receiver is still active (if I connect the lines TX & RX, I recover what I send.)   I would like to be in car 2-wire mode.   Can someone point me in the right direction?

  BTW: I use a cRIO-9075 mode of scanning and using Labview 2012 SP1 (windows), in the case where that matters.

  Thank you.

  Hi Tomherron,

  If you use the Scan Mode you can set the Mode of the transceiver using a VISA property node. The process would be:

  (1) place a property node VISA on the block diagram of your application.

  "" 2) click on the property node and select: Select property "parameters set" thread Mode. This will allow you to set or get the wiring for a particular port mode. In addition, allows you to have different modes of thread for different ports.

  (3) right-click and select any change in writing.

  "(4) the method of wire with the right button and select Create ' constant.

  (5) to choose what transceiver mode you want to use, click on the constant.

  RS-485/2-EchoDTR and RS-485/2-Auto options. Those who are what you are looking for?

• PXI-8431, without going into fashion with VB6 reception

  I use a PXI-1045 chassis with a PXI-8431 RS422/485 card and communicating via a VB6 program

  Send the output of the PXI-8431 RS485 module works well when it is in mode, the signal levels are approximately 1v and 3v for high and low, but when it is in fashion, that the outputs remain to 1v and 3v instead of going in passive mode and the two floating lines at approximately 2v with approximately 300mV differential as it should receive. This means that when remote devices send, the amplitude of the signal is about half as they compete with the PXI module and the center point of the two signals are 1v and 3v respectively. Our software does not receive the signals of the PXI module that is compatible with my theory, that it is always in the mode of sending and taking control lines, or maybe he's changed 4-wire.

  I swapped the PXI card and cards remotely with our good system and the problem will not move.

  I have eliminated ALL the material on the new ring by replacing it with a 67 on the way pin 9 connector plugged D directly Ohm resistor on the PXI card. With a scope, I can see that the new system will not in passive mode, but with the same connector the old system works OK.

  The only difference I can see between the 6 platforms old we who work and the new 2 that don't work is the new ones use the the NOR-XNET-PXI-8513 and the 'old' use the card CAN PXI_8464. This software would be in conflict? Are there any other updates to the software OR which could be causing it?

  Philip,

  3.5.1 series had some issues related to the read/write mode series 2 wires, I would recommend corresponding versions of driver with your working system or upgrade to the latest driver of series.

• Web sites are to lie on the side twice their normal width so I can see only the left half of a site unless I go to view "full screen"; ideas?

  Whenever I use Firefox the page so that I can see only the left half of the some site; that is half of the info useful page (the rest is cut) poster on the half right of my screen so that half left of my screen right bottom of the site. By using the maximize / restore does nothing. If I swap the display full screen, I see everything well, but of course I lose my toolbars. I installed the latest version of Firefox with no joy. I looked for a function of setting page nothing is done. I thought that time would fix it as it is something that has already happened, but was temporary. Other browsers work fine. I thought to uninstall then reinstall but I do not want to lose my favorites etc I don't have to. Thanks for your help in advance; I hope that this hike makes some sense.
  See you soon.

  It is very likely that the provider has configured its device for 100 Mbps, which was compatible with the interface of your FE 1841. If you configure the 1921 at a fixed speed of 100 Mbps and full-duplex, it should probably work.

• How to set programmatically the current node in a tree view of the ADF.

  Hello
  

  I'm trying to understand how to set programmatically the current node in a tree view of the ADF.

  My use case example is quite simple; If we take the sample application ADF Summit where under Management Summit, we have a tree view on the left with a list of high level of the country which in turn contain a subset of customers; then, in the right pane, we the customer detail information.

  What I'm trying to achieve is a solution by which I can add a new customer, commit and then to the tree show the client newly created as the currently selected entry.

  I use a pop-up dialog box to create my new entry of the customer and everything works well in this area, and my newly created folder is saved in the database.

  I know how to force the tree to cool off, but what I can't understand is how to do so, it highlights the newly created folder.

  Any help would be much appreciated.

• Can a name cookie webgate OAMAuthnCookie_ < host >: < port > _ < suffix > be configured?

  Hi all

  Can a name cookie webgate OAMAuthnCookie_ < host >: < port > _ < suffix > be configured?

  I came across the following document registration and management OAM 11 g Agents - 11 g Release 2 (11.1.2)

  I put UniqueCookieNames = disabled in settings defined by the user in the registration of 11g webgate.

  Copied files generated and restarted OSH.

  But it doesn't seem to work! always had cookie name OAMAuthnCookie_ < host >: < port > _ < suffix >.

  Any help will be appreciated!

  Kind regards

  This setting works for me in an ECC and the DCC. After you have configured this setting I see host: port withdrew the name of OAMAuthnCookie.

  I hope that there are no fault of strike in the setting in your case.

  WebGate version at my end is 11.1.2.0.0 according to the OPatch

  Whats webgate version in your case?

  Hello
  How can set my screen resolution of firefox (I know zom in and outside zom, but when I restart my firefox it chanaged to perviose zoom level)

  Hello

  Firefox on Windows is now after display, scaling options that can make the biggest text on screens at high resolution. There are several ways to solve this problem. See the Web pages are broad and fuzzy after update of Firefox - how to fix article for a suggestion. Here is another possible solution:

  • Type of topic: config in the Firefox address bar and hit the Enter key.
  • If the warning that this might void your warranty , click I'll be careful, I promised.
  • Search for layout.css.devPixelsPerPx

  

  • Double-click layout.css.devPixelsPerPx to edit its value. The default value is - 1.0 in Firefox 22 and above. Change it to 1.0 to run as in previous versions of Firefox.

  If necessary, further adjust the value of 0.1 or 0.05. Values between 1.0 and around 0.5 to reduce the size of the elements. Use a value greater than 1.0 to increase the size. For example, a value of 1.25 will increase the font size of the 125% to account for the default DPI setting in Windows 8. Check the value that you enter. Definition of a value that is too small will take everything away and too high will explode things.

  If the web pages should always be adjusted so you can watch the extension Default FullZoom Level or NoSquint .

  To adjust the font size for the user interface, you can use the extension of theme font & size changer .
