Transceiver mode on 485 card set to 2 Wire TxRdy Auto

our pcmcia card is set as above but the FIFO transmit buffer is dissabled in the port options is this correct?

Correct - on PCMCIA-485 cards, the 2-wire auto (txrdy) mode disables the transmit FIFO.

  • How to set transceiver mode to 2-wire TXRDY Auto from Visual Basic

    I am using a PCMCIA-485 adapter to interface to some RS-485 sensors. The sensors are connected using a 2-wire interface. I have developed an application in Visual Basic to control the various sensors. However, the application is dependent on the PCMCIA-485 adapter's transceiver mode being configured into the "2-Wire TXRDY Auto" mode. Presently I require the user to configure the transceiver mode by opening up the advanced setting dialog within the device driver for the adapter and manually setting the transceiver mode. I would prefer to have my application take care of this directly. Unfortunately, I cannot find any references that document how to do this.
    Can I use Measurement Studio Tools for
    Visual Basic to control the transceiver mode of the PCMCIA-485 adapter?

    Hello-
    There is a registry key in Windows that can change this mode:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Serial\Parameters\Serial1000X\TransceiverMode
    Try experimenting with it by hand first. It may also be necessary to reboot after changing this value.

  • Can I use two RS-485 cards over one bus?

    I have two PC's with a PCI-485 card each, controlling several FieldPoint modules. I want to implement some sort of redundancy where the inactive PC takes over the RS-485 if the active server fails.
    When connecting the RS-485 line in parallel, I get an error accessing the FieldPoint devices.
    Is there a known way of havinf two RS-485 controllers in the same line, or do I have to implemement some kind of switching to isolate the two controllers?

    If you are using NI's PCI-485, then you can setup a system like you described by setting both system's RS-485 ports to 2-Wire Auto. In this mode, the port will only drive transmit when it has data to send. Then your inactive PC watches for activity from the active server (either via the RS-485 port or some other mechanism like a network ping), and takes over when the active server goes down.
    By setting the transceivers to Auto mode and making sure the inactive server doesn't transmit unless it knows the active server is dead, you won't double-drive the bus.
    Note that 2-Wire auto turns OFF the receiver when transmitting (for 2-Wire communication). Even though you may be using 4-Wire cabling, this could impact your communication. If this is th
    e case, you could use 2-Wire DTE w/Echo which uses the DTR modem line (you have to assert/deassert this manually) to control TX Enable, but RX Enable is always asserted.

  • How can I use a PCMCIA RS-485 card from a LabView .exe?

    Hi all,
    We are going to be taking a LabView application and compiling it into an executable (.exe) for use by someone who does not have LabView.  This program requires use of either a National Instruments PCMCIA RS-485 card or possibly a USB RS-485 card.  The question is this - how do I use the card since we will not be able to run the MAXX software ahead of time to "install" the card?
    Thanks,
    Jason

    Hi Jason,
    On this deployment machine, you will need to have NI-Serial, NI-VISA, and the LabVIEW Run-time Engine. The version of the LabVIEW run-time engine will need to be the same version as the application was developed on. This can be downloaded from the Drivers and Update page or an installer can be created to install your application as well as the necessary run-time engine.
    If your application has RS-485 communication, you will need to install both NI-Serial and NI-VISA on this deployment machine. NI-Serial is the driver for the NI PCMCIA-485 or NI USB-485. The NI-Serial driver allows the devices to be properly configured and recognized in Windows. NI-VISA gives you the programming capability in LabVIEW. You can add both the VISA run-time engine and NI-Serial to your installer. You will need both of these drivers with the NI Serial hardware.
    You will have to run through the "Found New Hardware" Wizard when you install the hardware initially on this deployment computer, but setting up the baud rates and communication configuration should be done in your application as normal.
    I hope this helps!

    Note: If you have screen shots or documents. kindly share me.

    HP's support site has a doc on installation and removal of the SFP+ tranceivers:
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03421066&lc=en
    Figured I would post it since I found your question before I found the doc.

    I recently wanted to update my phone and so when i put it in recovery mode and tried to set it up it said that i had to enter the apple id that i used to set up the phone the first time but i dont know the information to my old account what can i do?

    You will need to remember or find the id that you used, without it you won't be able to re-activate your phone - if you are on the activation screen then does that show the first letter of the id and the email provider's name ?
    Do you know if you have any of the account's downloads in computer's iTunes library - if you do then you can get the id form that : Recovering a forgotten iTunes Store account name.
    If not then see if you can find it via http://appleid.apple.com : Apple ID: How to find your Apple ID.

  • Can not change transceiver mode in CVI

    Hi,
    I have two NI PXI 8431 serial boards installed in my PXI system. I can change the transceiver mode of one of the ports by using NI MAX (Attachment1).
    But I cannot change it by using CVI. My sample code is below.
    Before running the code, I change the transceiver mode of ASRL12 to "two wire auto" by using NI MAX. I save the configuration and close the NI MAX. And then, I run my sample code below. Status returns 0 all the time. But when I check in NI MAX, the transceiver mode is still "two wire auto".
    The software installed and versions are attached (Attachment2). My serial hardware can be seen on Attachment3.
    If you have any idea please let me know.
    Regards,
    Gökhan

    I want to use Visa Test panel to explain my problem. I write down what i did step by step.
    1. Open NI MAX and select one of the serial port (1.jpg)
    2. Click on "Open VISA Test Panel" (2.jpg)
    3. Select attribute "VI_ATTR_ASRL_WIRE_MODE" and note that current value is 0. (3.jpg)
    4. Enter 3 as new value and click on "Execute". Note that the current value is now 3.
    5. Close the VISA test panel by using the cross at the top right corner. 
    6. Open a new VISA test panel and select the attribute "VI_ATTR_ASRL_WIRE_MODE" again. And note that the current value is still 0, not 3. (5.jpg)
    So, I expect to see that current value as 3 at the last step. If I do something wrong please let me know. Any help will be appreciated.

  • LabView and Blue Heat RS-485 cards

    I am trying to get LabView to talk to a Blue Heat RS-485 serial card. Any comments from anyone.
    Bob Seegmiller
    NG UMS Ryan Aeronautical Center

    Scrapheap,
    Thanks for contacting National Instruments.
    Assuming you are using LabVIEW 5 or later, you will want to use NI-VISA to send commands to the card. VISA is a software interface that lets LabVIEW communicate to serial ports, parallel ports, GPIB ports, and other interfaces to instruments. The RS-485 card's ports should show up as COM resources just like any other serial port. You will most likely need to install the driver for that card provided by the manufacturer to get the ports detected.
    As far as the VISA programming goes, here is a link to a document which describes how to get started with VISA and serial:

    I hope this helps you get started wit
    h your application. Have a good day!

  • How can I set the insert date to auto update in Pages 5.2.2

    how can I set the insert date to auto update in Pages 5.2.2
    I am attempting to have the date in header auto update in a Pages file.
    I can insert it, but where is the AUTO UPDATE selection
    OS10.9.4
    thank you

    Apple never included the auto-update feature for dates in Pages v5.2.2. You would have to single-click the date, and deliberately update it.
    If you have Pages ’09 v4.3 in /Applications/iWork '09, then it will allow you to configure auto-update of the date field. Right-click on the date, set the format, and click the selection for automatically update on open.

    You are writing that in the perspective of having read about it here already. Repeated often enough that you encountered it somewhere in the posts.
    Users are flooding in here and don't know any of this. Of course we have to repeat everything endlessly.
    Because I like to give precise, understandable and workable answers to repeated questions, and Apple doesn't allow sticky posts here, I created a separate forum which users can consult to look up real answers, and contribute for themselves if they have something valuable to add:

    There is a section purely devoted to Pages 5. Add whatever answers you feel will lighten the problems of Apple's 'upgrades'.

    * Where have they acknowledged anything?
    ** They have barely anything listed, compared to the massive list of deleted features, and nothing but an extraordinarily long time frame considering they created the problems here and now. Apple has not said they will do anything at all about fixing the real issues, the biggest of which is that the new iWork apps break virtually all the work of existing users.
