Help with niSwitch example of DMM switch Handshaking

I have a bit of trouble getting my stint of PXI-2575 multiplexer and PXI-4071 DMM talking to each other.  "" They are located in a PXI-1045 chassis on which I am currently running the "niSwitch DMM Handshaking.vi switch ' example.

At the moment all I'm doing is read in a DC using this example.

SWITCH

Topology: 2575/1fil 196 x 1 Mux

List of Scan: ch0-> com;

Trigger entry: front connector

Advanced analysis of output: front connector

DMM

Type of measure: Volts DC

[...]

The destination full measure: external

Source of relaxation: external

Then try to run the VI, I get the following error:

Possible reasons:
Driver status: (Hex 0xBFFA6B9F) DAQmx 89120 error has occurred:
Terminal of source routing is not found on the device.

Make sure that the name of the terminal is valid for the specified device. See Measurement & Automation explore valid names of terminals.

Property: DAQmx_DigEdge_AdvTrig_Src
Property: DAQmx_DigEdge_AdvTrig_Edge
Source device: PXI1Slot7
Terminal of source: TrigIn

Status code :-89120

Of course, I'm new to this.  Help, please!

Thank you.

Hey Sean,

Looks like we have a differential of 2 volts. We will use 2 wires 98 x 1 and the following connections:

The help of switches:

On this basis, we can see in the lower right that CH0 + is pin 1 and CH0 - pin 2.  We need to hang the signal of 2 volts at pin 1 and pin 2 land.

We hang the DMM HI COM + (PIN NUMBER 173) and the DMM Lo-COM (PIN 174).

Now all we have to do is open switch Soft blanks Panel ('start' programs' National Instruments' OR-Switch), select topology (98 x 1 2 son) and connect CH0 to Com.  If we take a DMM measure, we should now read 2 volts.

Now that we have all this work, we will make it faster by using the example of transfer protocol you mentioned previously:

Suppose we want to connect channel 0 to com, take a measure, then connect the way com 1, take a measure, and then connect track 2 com, etc. all the way up to channel 15 to com.  A scan list that performs this operation is: "ch0-> com; CH1-> com; CH2-> com; Ch3-> com; CH4-> com; CH5-> com; CH6-> com; CH7-> com; CH8-> com; CH9-> com; Ch10-> com; CH11-> com; Ch12-> com; ch13-> com; CH14-> com; CH15-> com; ».

We can simplify this scan to help list of ':', the following: ch0:15-> com  This is equivalent to the same actions as above, but is much easier to watch.  I hope this is enough information to get started.  Let us know if you have any questions.  Have a great day!

  • Help with PXI OR 4070 DMM and OR PXI MUX 2501

    Dear alls,

    Sorry to post a simple question, but I couldn't understand it.

    My PXI1033 chassis has NI 4070 Flexdmm and NI PXI MUX 2501, block of connection OR-TB2605, 1 thread by MAX-mode configuration.

    I'm trying to measure 3 voltages (from 2V to 5V) by connecting them to ch0, ch1, ch2 MUX2501 (Terminal screw for example 67,66,65 and common screw terminal 27).

    Any device passes self-test to the MAX.

    I then use NOR-DMM/Switch Express, swap the added devices and also scan list.

    Trigger is PXI; Handshake (PXI trigger 0 and 1 PXI trigger)

    However, I could not measure all the signals.

    I also try with other examples in LabVIEW help, but have still no results.

    Am I missing something?

    And, although the trigger section is very clearly explained, I have no idea how the DMM to run his measure through switching and multiplexing. How DMM connected MUX?

    I noticed that the DMM and the switch share the same trigger bus (two of them bus trigger 1), but their local buses are different (DMM: local bus left/right = 2, 4, and buses premises MUX left/right = 3.5)

    Your advice is much appreciated.

    Thank you.

  • Help with hard drives and the "switch" statement

    All the

    I was wondering if you could please help? It's probably more to do with "powershell" than powercli but are... What I'm trying to achieve is the ability to create a function that runs through all my VM - counts the number of hard drives by VM - crosses EACH hard drive and gives me the ability of each of them. He then returns to a csv file (which iknow how to do). The segment below is pretty well what I want, but I was wondering if there was a way to reduce the amount of code! I tried using a foreach statement, but got stuck (PS - the maximum number of hard drives of our virtual machines can have is 5)

    I'm just using a switch statement, because that is what I "thought" answered the problem. However if there is a way I could get the same result without so much 'code' that would be ideal.

    Switch ($vm.harddisks.length) {}

    ($vm.harddisks.length - eq. 1) {

    ($obj |) Ajouter-Membre Noteproperty 'Disk 1' ($vm.harddisks [0] .capacitykb))

    }

  • need help with ojTree example of Cookbook

    Using NetBean 8.1 with Jet Plugin, I create a project called 'ojTree' locally

    replacement of home.tmpl.html and home.js (see 2 attachments).

    the tree widget is rendered, but no info is displayed as a result div, why?

    Html and js codes have been cut-and-pasted from Cookbook.

    Also, I noticed two things:

    (1) require is replaced thanks to define

    (2) No () ko.applyBindings is allowed (this application then?)

    Thank you

    Wen

    Hi Wen,

    I misread your question.  Sorry about that.  You have the ojTree component rendered correctly, just the relationship between the ojTree and the 'result' div that does not work is.

    From the quick start model you use, using the ojModule function to load different pages, this module handles all calls to ko.applyBindings for you.  The ojModule function provides a lifecycle of the API, you can learn more about of the located JSDocs to the:

    JSDoc: Namespace: ojModule

    You can either set the function that is listed in the cookbook, in one of the functions of reminder of the cycle of life, or you can use the 'optionChange' on the ojTree itself component event make the connection between the two components.

    I think that the optionChange event is the best way to do it.

    Your code would look like this:

    HTML

    link data = "ojComponent:"

    {

    component: "ojTree."

    optionChange: changeHandler.

    selectionMode: "multiple."

    data: {data: getJson},.

    DND: {rearrange: "enable"}

    }">

    JavaScript

    In the viewModel, add the callback like this function:

    self.changeHandler = function (event, ui) {}

    If (ui.option == 'selection') {}

    display selected nodes

    var selected = _arrayToStr (ui.value);

    $("#results").html ("");

    }

    }

  • Need help with network home using Airport extreme

    I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

    Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

    My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

    Any help you can provide would be great.

    I would like to get the return tech to help you to...

    But it is likely that something (or someone) has tampered with the settings.

    The layout is fine... but you can cause problems with the network by creating a loop.

    This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

    Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

    Unplug the two AE you have that function as extensions...

    Turning off everything else... then it works again...

    Do it in this order.

    Modem... Wait 2 min

    AE... Wait 2 min

    Switch.

    Now check that the network is working properly... power of customers in various locations and make sure everything is good.

    If so, then manually reset the two AE of factory and redo their installation.

  • Need help with the data storage store, local array and network connections

    Need help with my ESXi 4.1 installation

    My hardware:

    I built a server with an Asus P6T whitebox, i7 920, 12 Gig RAM, NIC, Intel Pro1000 PT Quad, 3ware 9650SE-12ML with 8 1.5 TB SATA green in a raid 6 array gives me about 8 + TB with a spare drive all housed within a NORCO RPC-4220 4U Rackmount Server chassis.  I also have a 500 GB SATA drive which will hold the ESXi and virtual machines.

    The network includes a firewall, Netgear Prosafe FVS336G, GS724Tv of Netgear ProSafe 24 port Gigabit Managed Switch on a dhcp cable modem internet service provider.

    I also have 2 old NetGear SC101T NAS disks (4to) I want to connect to the system how some - at a later date have... data on them and want to transfer to the new storage array. I always looking into the question of whether they will work with ESXi 4.1, or I might have to only access it through Windows XP.

    My Situation:

    I have already installed ESXi 4.1 and vsphere client with no problems and it is connected to a dhcp cable internet service.  I've set up host via a dynamic DNS service name give me a static hostname on the internet.  I installed three machines to virtual OS successfully at the moment and now want to first start by creating a multimedia storage server which will use some of this new 8 TB array, then separate data storage for use with a web server small overhead storage and a backup.  It is a domestic installation.

    Help with the data store and network:

    I was doing some reading, because I'm new to this, and it looks like I'll probably want to set up my table via ESXi as a nfs disk format.  Now, the data store is usually in another physical box from what I understand, but I put my readers and ESXi all in the same box.  I'm not sure that the best way to put in place with grouped network cards, but I want to make this work.

    I understand that in ESXi 4.1 using iSCSi LUN must be less than 2 TB, but nfs - I should be able to add a bigger partition then 2 TB (for my multimedia) in nfs, right? or should I still add it separately as a separate 2 TB drives and then extend them to get the biggest space.

    Any suggestions or direct resources showing examples on how to actually add some parts of the table as data warehouses separate nfs.  I know that to go to the configuration tab, and then select Add to storage, and then select nfs. I have not my picture, but it's here that I don't know what to do because ESXi 4.1 system already has an address, should I put the same thing to the new data store array also (will it work?), and what should I use for the name of the folder and the store of data... just do something to the top.  I thought to later install Openfiler (for a multimedia storage using this table server) as a virtual machine, use the table with esxi so that I can access the same storage space with widows and linux-based systems.

    I also know I have to find a way to better use my quad nic card... put in place of virtual switches, grouping, etc HELP?

    Any direction, assistance, similar facilities to sample, suggestions or resources that would help would be great. I did a lot of hunting, but still a little confused on how to best to put in place.

    You must think of VMDK files of large databases with records of random size guest go read some data (a DLL or an INI file), maybe write some data back, then go read other data. Some files are tiny, but certain DLLs are several megabytes. It's random i/o all and heavy on the search time. IO Opsys is small random operations that are often sequential (go read data, write data, go read other data,...) so that deadlines are critical to the overall performance. That's why people say OPS are / s of reference and forget the MBs flow. The only time where you bulk transfers are when you read media (ISO files).

    Well, now forget all this. Actually the disk activity will depend on the specific applications (database? mail server? machines compiler?), but the above is true for boots, and whenever applications are idle. You should see the profile to know.

    RAID 10 is faster (and often more reliable) than RAID 5 or RAID-6 except in certain specific cases. In General RAID 10 is ideal for many random writes, since the calculation of parity for RAID-5 and - 6 adds to the overall latency between command and response - latency is cumulative if a little slow here and a little slow it adds up to a lot of overall slow synchronous especially with e/s on a network. OTOH RAID-5 and -6 can produce faster readings due to the number of heads, so you can use it for virtual machines that transfer bulk. Test. You may find that you need several different types subdashboards for best results.

    You said 3ware, they have some good grades on their site, but don't believe it. With my 9650 that I found myself with only a couple of their recommendations-, I put the (simple) table for allocation size 256 k, nr_requests at 2 x the queue_depth and use the planner date limit. I had the habit for the Ext4 file system formatted with stride and stripe-width synced to the table and used the options large_files with fewer inodes (do not use the huge_files option unless you plan to have single VMDK files in the terabyte range). Use a cache of great reading in advance.

    Virtual machines use VMDK files in all cases except raw iSCSI LUN that they treat native disks. VMDK is easier to manage - you can make a backup by copying the file, you can move it to a PC and load it into another flavour of VMware, etc. There could be some features iSCSI to your San as a transparent migration but nothing for me. NFS has less chatter of Protocol if latency lower times to complete an operation. NFS is good to read and write a block of data, that's all it boils down to.

    UPS is good, but it won't help if something inside the machine explodes (UPS does nothing if the PC power supply goes down). If the RAID card has an option for a battery backup module, so it can contain some writings in memory and may end up the disk i/o after replacing the power supply. 3ware also limits the types of caching available if help is not installed, and you get just the right numbers with the module.

  • I'm suddenly needing help with my browser Firefox (6.0.2)

    Hello
    I'm suddenly needing help with my browser Firefox (6.0.2)

    (OS: I use Windows XP).

    When I open the browser, I don't see is a totally white screen of white, with all the toolbars at the top.

    I know that my physical connections are very good: I have tested the modem, turned the pc market etc and I can also receive/send emails.

    This problem started today, September 8, 2011 and has never happened before.

    Is it a coincidence that Firefox itself to day before I disconnected yesterday evening? Could this be something to do with this particular new update?

    I also noticed that just before I "opened" Firefox, I now get a small box indicating:

    [JAVASCRIPT APPLICATION]
    Handl exc in Ev: TypeError: this oRoot.enable is not a function

    This never appeared before - I hope that it offers a clue has what is wrong.

    The browser not be stuck in Mode safe, said by the way.

    Of course, I can't find solutions to the problem on the internet, I don't physically see all Web sites!
    (A friend sends this request in my name from their pc)

    Any light you can throw on this problem of confusion would be much appreciated. I'd rather not have to uninstall and reinstall Firefox if possible.

    If the only option is to uninstall Firefox and reinstall from your site, I'm also in trouble (I can not see the internet or download).
    In this case, would you be able to send the .exe file as an attachment to my e-mail address? In the affirmative, please let me know and I'll give you more details.

    Thanks in advance.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  • Help with the Structures of the case

    I have a problem switching between the true and false cases between the structures of the case. I'm writing a VI that generates a random number between 0 and 10 once every 0.5 seconds, and then adds the numbers until the total reaches or exceeds 100. At that time, it should start to subtract the number generated at random until it reaches 0, then switch again adding etc.

    I have a problem switching to the case of 'false' once the sum exceeds 100. If anyone can help with that would be great!

    To make things more simple exchange the Boolean value for an enumeration with only two values you can call "Count Up" and "Count Down".

    Create a second shift register to hold the enumerated value specifying whether to "Count Up" or "Count Down". Initialize the new register shift to count up, and in the case of "Count Up" in the structure of the case, increment the value of data and test to see if it is greater than 100. If this is not the case, do not change the value in the registry to shift direction. If data has exceeded the limit, change the values in the shift of direction register account to "Count Down".

    In the case of 'Count Down', decrement the value of data and test a value less than 0. When the value of the data is less than the lower limit, change the values in the change of direction of the County Register to "Count Up" and you're done.

  • Help with multitasking it please?

    Since I got my phone (Moto G 8 GB), multitasking has been terrible. I love the phone, but it's his left out major. Switching between the 2 applications at the same time generally involves having to reload the entire application, even some of the lighter applications such as contacts. I looked in the settings and everything is OK, as the apos as the default background. Also, I don't seem to have any heavy applications running in the background. Facebook is the heaviest app I have on my phone. I wonder if there is anything I can do to remedy to this or if anyone else has this problem?

    When you switch between applications, they restart because the system runs on the RAM. You see the message to reboot on some of these processes because the system killed these processes in order to keep others running and to free some RAM when its need is why you always have a bit of free RAM.

    Even the Air iPad with 1 GB of RAM, even that bike G, has problems, keeping applications running in the background. I'm afraid that this problem is quite normal if you have applications that run in the background taking up RAM. The system kills just the process relatively little important, as Google play music and display of WiFi, to keep others running and have at least a little memory available when it is needed.

    So you're an Android user average above that you have several applications that won't install average consumers, so I recommend going with a phone in the future who has at least 2 GB of RAM.

    P.S. I read in places that Motorola is aggressive with background applications to help with the battery, so maybe that is why the system cannot even keep apps simple people in memory, even if you have still a few available RAM.

    just install XP Home on a computer and having some problems.

    use a disc of SP2, and then immediately installed the SP3 update. then, I installed IE8 .exe Microsoft site. After that, connected to Windows update and DLed all until was completely updated and there is no more updates.

    Well, it seems a little weird. one of the services is named wrong. "Human Interface Devices" Department is still called 'HIDDEN', when it should be the former since SP3 should change the name. and some updates seem to be missing from the Add/Remove. It just does not match when comparing it to another computer that has XP SP3 perfectly up-to-date. for example, IE8 has only 3 security updates listed (compared to my other computer 12 or so updates), is it because unless it is installed with the .exe file and it already included more updates?

    a little worried. you want to make sure that my computer is completely up to date and it is not all the current problems.

    Usually, if you are installing the stand-alone package of SP3 more updates including security and critical updates are installed. This may also depend on the features and programs installed on the system.
