• Satellite L870: Problem with USB to serial interface with FTDI chipset

  Hi all

  bought a L870 year last to run software amateur radio via USB to the serial interface.
  Interface uses the FTDI chipset.

  The problem I have is that the switch on the led on the interface flashes green to red several times to indicate that it works, but then must remain on green but task on every minute she goes through the same process again.

  All the controls on the drivers and the Manager of devices indicates that everything is ok. No problem with interface on computers laptops happens or advent.

  Is there anything on the Toshiba laurys usb ports every minute.

  Thanking you in advance for any ideas

  First of all, I must say that there are different models of L870 Satellite on the market supporting different hardware and software. Some are preinstalled with 8 and some Win with Win 7.

  In addition the L870 supports USB 2.0 and USB 3.0 standard.
  If you recommend to check the different USB ports and check if your software works correctly with the USB 3.0 standard.

• Communication with the niVisa (GPIB) do not work next to a serial interface

  Hello

  I programmed an application in C++ (Visual C++ with MFC, running on XP). On the one hand, I control devices of different measure (also from different suppliers). All communication is done with niVisa (Version 4.6). On the other side, I send remote commands to a generator via the serial interface. To do this, I use CSerialPort, it's a Wrapper MFC of the Windows API. Thus, niVisa is not used for the serial connection.

  It works without any problem until I connect the measurement equipment (any type of) via Ethernet.

  When I now connect the scope via GPIB (I use a NI PCI-GPIB), communication works without any problem as long as I wouldn't send anything on RS232. After I send something to my generator (and close the com-port), the next Commander of VISA will give me an error (VI_ERROR_ABORT). Now, I can log in again and everything works normally again (until I have again send something on the com-port).

  For me, it's a really strange question. Any ideas? Any help?

  Best regards

  Michael

  OK, I finally found the problem.

  When you use the serial port, you can write data with normal writing (WriteFile()) function or with the tip (WriteFileEx()). Do not now ask me for more details on the difference, it's something with the mode "" overlap...

  After I send all the data with WriteFileEx, VISA-connection via GPIB produces an error. So I went to the basis of WriteFile() and everything works. Don't ask my consistency betwenn VISA (with GPIB and just GBIB) and the connection series. I'm just happy right now...

• Wayne Kerr 7720 Impulse Tester (serial interface) driver needed

  Anyone know where I can find a driver of Wayne Kerr 7720 Impulse Tester LabVIEW. The tester has a RS232 interface. Also useful would be a good source to learn how to write such a series driver where I can't find one.

  Thank you.

  I don't know what you mean. The I tried is a self-extracting zip with a couple of files llb and those are certainly valid extensions.

• Arduino restarts my PC when it is used for the serial interface

  Hello

  I use the example of continuous series read/write and other simple programs to read data from the Arduino board, but I am facing a problem that my PC restarts wih blue screen when you read data from Arduino for 5 minutes.

  I don't know the reason and tried various solutions, including adding the number of bytes to Serial Port to connect with the VI series of reading.

  Kindly guide me what could be the possible reason for this problem.

  Concerning

  I had this problem too - my PC would crash on average about once a day when connecting an Arduino data.

  Someone on these forums proposed defining the synchronous and not asynchronous read VISA. Right-click in the VISA reading and select ' E/s synchronous Mode' > 'synchronous '.

  I tried this and it seems to have worked - I have not had a crash for about a month now. I have no idea why it would make a difference, but it seems.

• serial interface port with xilinx Board with LabVIEW

  Helllo everyone,

• Keithley 6517 helped serial interface

  Hello

  I use an instrument, the electrometer Keithley 6517 A, to control using Labview and am very new to this software (1 week). All I have is a RS232 cable. I downloaded the driver, but it is for cable IEEE 488.2 (GPIB), which does not work with RS232. I did some research and discovered that you can use the SCIP language to control the instrument using RS232.

  Can someone please help me to write a simple program that uses the RS232 cable to control the instrument?

  The program I want to implement is essentially to measure the change in voltage between the two wires, while incrementing the voltage source integrated instrument by all about 0, 1V.

  For ex, the source voltage will increase by 0.1V, wait for about 3 seconds to stabilize the blood reading, read and record the voltage in a file, repeat after increment of 0.1.

  Information that may help

  Instruments: Keithley 6517 has

  Cable interface: RS-232

  Software: Labview 8.5

• I reformatted computer that had vista on it, but did not come with cd how vista back on it?

  OK so I got my computer and I've had for about 2 years with no problems then I have a virus and I need to reformat it but I forgot that the computer came with a vista installation CD or recovery CD, so I don't know how to get it back, but I don't have the thing to sticker the serial number on the back of my computer vista It was still Vista Home Basic 64 - Bit thank you.

  Vista Media recovery obtaining and/or using the Vista recovery on your computer Partition to factory settings .

  There is no Vista free download legal available.

  Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

  Normally, they do this for a cost of $ small.

  In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

  See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

  Normally, you have to press F10 or F11 at startup to start the recovery process...

  Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

  Also ask them if it is possible to do the recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

  They will tell you how to do this.

  Every computer manufacturer has their own way of making recovery disk/s.

  Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
  A good Vista DVD contains all versions of Vista.
  The product key determines which version of Vista is installed.

  There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

  If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

• Factory reset for VGN T37GP and how to back up the files of windows before hand

  I have to do a factory reset for VGN-T37GP (Australian model?)

  I need to reload the Windows operating system and delete the previous owners files.

  There is 1 link on which I can click on the Sony site that will do it without too much hassle?

  I don't have a copy of the Windows operating system either, I was wondering if Sony which will provide once I click on the link? (There is a sticker windows with serial details on the back of the Vaio, so I think that Sony will provide it).

  Can someone direct me to where I can find a link to the question above? Thank you.

  Also noticed a lot of heat in the upper left rear of the Vaio. I'm guessing that it may break soon.

  Model VAIO: VGN T37GP

  What is the life expectancy of the Vaio model: VGN T37GP? On average?

  I don't have the recovery disks. They are free to download?

• Determine the type of serial, 485 interface or 232

  Hello

  How can I determine the mode of a serial interface wiring? Another way, if it's a 232 or 485.

  The approach to try to connect with different threads is not the problem, 232 COM caught if we try to use a 485 mode. Solution, reset the onboard computer.

  Kind regards.

• imitate running a script to run Labview tera - serial communication

  Hi I have an anemometer which I am trying to communicate with via the serial interface. I am connected via a USB converter to 485. The manufacturer of the anemometer provided two scripts of term tera to communicate with the device. When I run scripts in tera term anemometer reacts as expected. When I imitate (or so I think I'm) orders in Labview, I get no response.  Please see the attached document for more information.

  I'm not familiar with the language of terms of Tera, but what I found on the internet I guess that there is more information (CR & CRLF variable defined by the code2str function), which is in fact the echo back on display "00TR 00012 '.

  Any ideas?

  Thank you

  -Scott

  It is probably sending a return trolley/line.  (or just one or the other).

  I suggest using a program like Portmon using Teraterm to see what is actually sent and received.

• Tecra M11 - 17V - identify the serial port on the docking station

  I have a laptop Toshiba Tecra M11 - 17V, which I often use with the docking station that accompanies it.
  There is a DB9 serial port at the back of the docking station, but I don't know what COM Port.

  I use Windows 7.

  In the device, COM9 Manager - COM22 are identified as Port BT (bluetooth). Com7 - COM8 are RIM Virtual Serial Port v2, COM17 is Prolific USB-to-Serial Comm Port and COM18 is USB-Serial CH340.

  I thought that COM17 or COM18 were the most likely candidates, but have not been able to get to answer using one of them.

  I connect a Psion 5 (Comms app) to him and have developed ports and the Psion 8bits, 19200 baud, no parity, 1 stop bit.

  Hello

  > There is a serial port DB9 on the back of the docking station, but I don't know what COM Port, it is

  I think you have misunderstood something wrong
  COM ports in Device Manager are virtual com ports
  There is no link between a serial port and a virtual com port.

  I have a question: what docking station you have exactly?

  I had an express port replicator and this device required an additional serial port driver installation.

• NEITHER 9870 Serial Port Communication

  Hello

  I have the module 9870 serial rs232 on 9073 cRIO chassis. I have watched the series loopback example, added to my project, changed the entry node to point to the serial port on the right. It works fine when I use a closure connected the cable to the serial port.

  However, when I connect the port to the serial port on the back of my pc (using the cable series of woman to woman) and run the "Serial Loopback DMA Rd (host) .vi" I see no data being sent on my PC com port hyperterminal. Also if I type any character on hyper terminal I see their receipt by the LabView program.

  Why is this happening? that is, the example works well with a loopback adapter and not when it is connected to other serial port?

  Any help will be appreciated.

  concerning

  Bastien

  Hello

  You have all the details on the cable you are using? You may need a null modem cable.

  All in hyperterminal settings the cRIO? IE: Baud rate/parity/start and stop bits etc.

  Could you take a screenshot of the hyperterminal settings and the windows serial port settings? Could you attach your cRIO VI?

  Thank you very much
