• Device series problems

  Hey everybody,

  I am quite new to labview

  I plugged a device series 232 rs to my computer and installed the drivers for it and all that good stuff. I open hyperterminal and had no problem of communication with the module.

  When I open one of the example screw series in labview, I tried to send commands and I kept getting an error message saying that it had expired.

  BUT

  When I sent the same command 5 or 6 times at the same time IE

  VM 1-0

  VM 1-0

  VM 1-0

  VM 1-0

  VM 1-0

  my module receives the command and functions very well.

  What hurts?

• Max and LabView can communicate with the device series

  I'm trying to connect a balance Mettler - Toledo JL - 6001 to my computer as an entry for a LabView program through a RS-232 to USB line.

  In MAX, I get sometimes (but not always) the error message "the resource works correctly, but VISA cannot currently access."

  On the general tab for this port, I get the message' VISA returned this camera when searching for resources, and MAX was able to use VISA to analyze the resource name.  The resource was busy, so MAX could not successfully log on VISA to the device. »

  In LabView, the program runs, but I get all zeros as output which is definitely not correct.

  I tried deactivation and activation then the port. I tried making sure that no other program is using the device, and then restarting the computer.

  I'm not sure I have the correct driver installed for this scale (MTT coach), (they do a lot of balances and some pilots and was not sure than to use). I don't know if that makes a difference in MAX.

  A few tips for how to get balance and the MAX to communicate? Also, I know almost nothing about the transfer of digital data / series a response very dumbed down would be greatly appreciated.

  Thanks in advance,

• Can LabVIEW control a device series (RS232) via a USB port on a Mac?

  Using LabVIEW 6 and operation of G4 Mac OS 9, it was once possible to use a USB port for control and acquisition of data of a pH meter in our laboratory. Only, we used "Serial Port Init.vi" and wired to port #0, which referred to the USB port. We connected the connector DB9 to the pH meter to the Mac's USB port via a USB-to-DB9 adapter. LabVIEW 6 could then send commands to the pH meter and acquire pH values of him using the serial port, reading and writing icons. I try to do the same thing now using LabVIEW 8.6 on a Mac Pro OS 10.5.6 and leads nowhere. The simplicity of LabVIEW 6 is long gone, and it seems to be necessary to use VISA icons. When I write the vi using the icons series VISA, three potential serial ports appear to be available. However, the vi gives an error message, except when I choose a specific of these, ASRL2::INSTR, under the name of the resource, in which case the vi runs, but there is no communication with the pH meter. I can't understand what physical connector on the chassis Mac corresponds to ASRL2::INSTR, but it is does not seem to be the USB key. I tried to write the vi using the icons of VISA USB of LabVIEW, but which requires knowledge of USB communication protocols which is beyond the expertise of this chemist. So, I'm almost at a loss what to try next. I could buy a serial RS232 card to install in a PCI Express slot in the Mac, hoping that he will be recognized and can be resolved by using the icons series VISA. However, as it was once trivial to perform this task of communication via the Mac's USB port, it seems that it should not be necessary to buy another card. LabVIEW continues to become more and more complicated, and if she doesn't get any more improved, it may not work at all. I've been programming LabVIEW on Mac for almost ten years and she became gradually more frustrating. In any case, is - anyone out there fought USB / communication series battle on a new Mac and won? If now it is impossible, no matter which allowed to pass through a RS232 serial installed in a Mac Pro card? Any help will be appreciated. Thank you.

  Ken1,

  I don't have a chance to see the USB-serial last night.  I'll make a note to try it again tonight.

  Dennis is right.  You need to focus on the determination of what works or not in communications.  Look at the system information (Apple menu > about this Mac > more info...).  Then select the USB item in the list of the contents of the left column.  See if USB devices to look like they could be serial port emulators.  I don't remember exactly what they are called.  If the device doesn't appear like USB Raw, it probably means that no driver has been installed.  You can unplug the unit and see what are the changes.  This will tell you if the operating system sees the device.

• How to connect the port device series to the Blackberry without Martin Simulator

  Is there a program that can interface with the Blackberry Simulator to connect to a device connected to the serial port of the computer to simulate a Bluetooth connection?  I can't believe that Martin is the only way to do it.  Martin offers a free demo version sort of their program?  I searched everywhere but found no one.  I don't need a bluetooth receiver real but just the software in order to supply data from serial port to the Simulator (and I guess that convince the Simulator data from serial port to a Bluetooth device).   Thanks for any help that anyone can provide.

  I'm not aware of any device that will help with this.

  Two suggestions:

  (a) you can write some sort of test, that will feed a data script as if it came from a Bluetooth device.  I got it done in the past - it does not test the treatment of Bluetooth, but it allows you to drive the application program.

  (b) it is not really difficult to test on the device.  Little painful to recompile and reload, but if you have a test drilling (a), then you are only testing the Bluetooth part, which you won't be able to test a connection series anyway.

• Problems with USB pnp devices series Tecra

  Hello
  I have a lot of problems to install usb flash drives as pnp devices. It should install automatically as it did on my desktop and other mobile colleagues.

  I am running xp professional and all that happens is the found new hardware wizard appears, and fails to install. I tried to update the BIOS and Chipset with downloads from this site but nothing works. I ran the diagnostics and the usb drivers and features are ok.

  Any help would be appreciated.

  Hello

  Everything you wrote is really mysterious. It will be interesting to know what model Tecra you have exactly, and this occurs when you install the operating system using recovery DVDs delivered.

  I can't really imagine that this issue occurred all of a sudden.

• I want to compare live data that leaving a device series after every two seconds.

  Hello

  He is Mohammad. I am new user of labview.

  I'm working on an instrument of communication in series. In two seconds, I coded for a single data point of the instrument. My problem is I want to compare the current data point with the previous immediate. How can I compare each time that the current data point with the previous. Can someone help me please?

  With impatience.

  Mohammad

  If you graph these data:
  Replace the while loop with a loop For.

  So if wire you the data out of the loop, it will be automatically built into an array.

  This array can be passed to a chart in Microsoft graph if you want.

• Is it possible to simulate a XNET CAN device in MAX?

  I ordered one material OR 2 ports 9860-selectable OR XNET C Series Module and 2-wire transceiver capable of CAN - FD.  Of course, my time line for implementation is tight.  I would like to write the driver I need before that happens the hw.  For the many materials OR I can go to MAX and simulate the device.  It seems that this option is not available for communication devices series like the one I ordered.

  Is it possible to simulate my device in order to create a session and debug my driver?

  Thank you

  Mick

  Hi sherlieferdilus,

  There is no way to simulate actual XNET like DAQ hardware modules. For our simulated DAQ hardware, we are able to return dummy data (for example, a simple sinusoid to the analog inputs), but XNET will have something completely different on all buses and behave differently on this basis. More, to use a XNET database for tests must be frames or signals corresponding to the information contained in the database from your CAN Bus.

  That being said, OR XNET is fairly simple to use with a large number of examples in our search example LabVIEW for you to investigate and begin to work from. Also, you should be able to start working on your OR-XNET database, if you have not already and that you plan to use a (this is required by all Sessions of XNET except framework flow Sessions). If you are not already familiar with XNET, I would take this time to study some of the examples and take the time to view our material OR XNET and the manual of the software. In particular, learn about the different types of Session and the types of synchronization you can use so that you are already familiar with them once you receive your material.

• The PXI-8512 does support the series 2 filter or a similar mechanism to filter the messages?

  Hello

  I need to buy a couple of cards CAN interfaces for my test application and I wonder what you choose

  I already used a PXI-8461 to obtain data of the customer model under test, and due to the fact that sometimes the client bus can be very busy, but most of the messages is not interesting for my system that I use currently series 2 comparator/mask/filter to filter only the interesting messages.

  Without this filter, the PXI-8461 often returns an error due to overloading of the bus. With the filter, everything works perfectly

  Now I need to implement several testbeds with this same feature, and I plan to move to the new PXI-8512 for new.

  My question is: is the most recent PXI-8512 a device series 2 institutions? Support the filter 2 series or any other mechanism to avoid problems on the busy bus?

  Thank you for your support.

  Kind regards

  Davide

  Hi Davide.

  the PXI-8512 isn't a series 2 device. The PXI-8512 is a device of the X-NET family. X-NET is the technology whose use OR in support of CAN, LIN and FlexRay with a driver API. Series 2 devices use the former NI-CAN driver that only supports the CAN. All of the new devices are devices X-NET.

  Take a look to the following document:

  NI-CAN for NOR-XNET application migration
  http://www.NI.com/white-paper/9717/en

  On this page you will find the following statement for the function that you are already using:

  Transceiver filters were traditionally indicated for applications where only a few CAN IDs have been considered on a bus high load. In some cases, material NI-CAN support the bandwidth of the full bus, which leads to a buffer overflow. The hardware architecture OR XNET uses the engine NOR-XNET DMA-driven to eliminate the occurrence of buffer overflows. CAN of NOR-XNET interfaces are able to handle high load bus and transmitting at the maximum rate without coupling to buffer overrun. If your applications use the hardware filters extensively, NOR recommend setting up CAN opposes, or by reading the bus while using Network Interface objects. The best option for these applications is to modify your code to use the API OR-XNET native.

• Device requires two characters of endpoint to complete the "READ" command

  Hello, I'm the Labview programming, an application to receive data from a device series. One of the problems is that the unit always displays CR + LF after each measurement. However, in Labview, it seems that a single character is allowed. This causes problems for me, because when I choose LF as the stop character and I'm scanning the reading string, it contains the other termination character, who is sent to my data table, file and waveform, and it also fails to plot the data in the table of waveform, since the digital channel is not pure numbers.

  Is there a way to get around this? Thanks for any help.

  Define LF as your character to terminate employment.  Search for the string of the CR function and return the data before the CR.

• reading and writing series sometimes works, sometimes expires

  I use the series on the VIs VISA to acquire data through an instrument.  After you have configured the port, I have send the instrument the order "AZK" followed of a newline (string hex "2A 61 7A6B 0D").  This brings the instrument to trasmit data.  When I do this in Hyperterminal with the same port settings, it works every time when I repeat the command as quickly as I can without any problem.  When I start my VI in LabVIEW, sometimes it works and sometimes it isn't (work maybe 25% of the time).  When it works, the data are displayed in an indicator very quickly.  When it doesn't work, I get a timeout error (10 seconds).

  I think the data string is ~ 330 bytes; Since I'm troubleshooting, I have it reduced to 20 bytes in order to ensure that the reading series is not waiting for more of bytes.  I also tried to extend the timeout, but it doesn't help.  Thinking this was maybe timing, sequence, or buffer related, I also tried to write and read in frames separated from one frame of the sequence and also tried an initial framework with clear VISA to clear the buffers before writing and reading, but none of this has helped.

  Any ideas why this might work a while but not others?

  I have attached a VI that I use to try to get this working.  (Note some data, the analysis of operations, as well as the VISA read a previous VI, but they have not been configured for this instrument of entry again and only the input string of reading indicator is significant at this time).

  If I can't get this to work, my rescue is rule automatically the instrument on trasmit on a certain frequency (like 1 sec) and acquire these data.  I was able to do this successfully with another device series.  But I wanted to be able to have LabVIEW to control the timing of transmission data as this unit has this capability.

  Thanks for any help.

  You can try adding a delay between characters like Hyperterminal does.

  And please don't say that you use the continuous run button. That would be a mistake.

• FirePOWER vs 7000 Series Appliances Cisco Cisco FirePOWER 5000 Series Appliances and Security more

  Good evening

  I put this thread to better understand that we enter firepower vs FirePOWER 5000 Cisco Cisco 7000 series devices Series Appliances are stronger for AMP, IPS and URL protection.

  It is accurate to say that Cisco FirePOWER 7000 series devices is more powerful and safer such as defence AMP IPS and url vs Cisco Appliances of series 5000 firepower?

  about security Plus (a feature of the router ASA5506H-SP-BUN-K8) whose security it provides?

  have a good answer

  8000 and 7000 series devices are devices that came with the acquisition of Sourcefire. Strictly, they perform the Sourcefire software only and do not have the features of the ASA (routing, AnyConnect VPN and many others). They usually also provide larger flow capacities during execution of all services of firepower (IPS, AMP, AVC and characteristics of the URL). So if you don't need all the features ASA then the 7000/8000 series devices is probably a better choice.

  The ASA5500-X series includes the best of both worlds. The ASA and Sourcefire software are running on the same box. So you can still use all of the functionality of the SAA and then also re - direct specific traffic to the Sourcefire module for additional inspection.

  I hope this helps!

• How to make multi-function devices under linux (composite) in windows

  I was able to compile my Linux machine to a composite widget. (Series + mass storage)

  When I plug the unit on a Linux PC, the operating system was able to detect and use the two functions. But when I plug it into Windows, it is just detected as a "Gadget Composite multifunction" and I can't use it as either a mass storage or a device series.

  How can I do to make this work in Windows. Deploys a really essential custom driver for this task? If so, how this is achieved the way less "painful"?
