Application of specification USB-TC01 for clarification

Dear people,

We want to clarify a few accurate data on the temperature measurements using the USB-TC01 + thermocouple type J.

We're just not sure how to use the specifications given to predict the available precision (and resolution) in the following scenario:

the housing of the sensor is placed with the wire of type J in a laboratory room, and the room temperature may vary between 20 and 25 Celsius degrees. What is the available accuracy and resolution in this case (since comp. cold welding circuit is "in the room")?

Furthermore, we need to measure the temperature in our experience with Celsius at least 0.05 accuracy and the same resolution.

If USB-TC01 is not able to meet our needs, you can recommend a product OR different?

Thank you very much!

Standard thermocouple are usually accurate to only a few degrees, what are the specifications of your J proposed type?

EDIT: I suggest to use a platinum RTD with 4-wire as the topology of the sensor connection.

  • USB-TC01 gives error-201165 "firmware for this device is too recent.

    Not sure where else to this post, but the USB-TC01 DAQmx uses, so maybe someone recognizes this.

    I plug it to the USB port and it lists very well.  It runs the application very well canned.

    But when I try to take data under DAQmx 9.1.5 I get this curious message, as well as boards "Downgrade of firmware for this device" I don't want to do that.

    EDIT: I see that the firmware of the device is 1.1.0f 1

    The specifications of the USB-TC01 don't say what version of DAQmx is necessary, although 9.1.1 supports the device.

    I tried on XP and Win7 with the same result.

    TIA

    I guess that "ancient" is relative.  Budget and LV9 story of me and I have to stay on the DAQmx version.  But NEITHER finally took me in his Web and it's time for an upgrade.  A trial version of new LV and 9.9 DAQmx solved, of course.  I just wish that error message had been less weird.  At least, it is here for someone else could find an answer, no matter how obvious.

  • Run a specific USB device automatically when AutoPlay is disabled?

    Very well. I decided to turn off the automatic reading and I want to control what makes a program when a CD/DVD or a USB device is inserted on my PC.

    How can I start a device specific USB automatically runs with AutoPlay disabled?

    The USB device, I am trying to run automatically is a USB from Magic Jack phone; Magic Jack program should start automatically and I have auto play off it takes about 1-2 minutes to load the application once I plug the device into the USB port.

    I hope I'm lucky and there is a solution. :-)

    Hi ByteBowser,

    Welcome to Windows Vista answers Forums!

    From Windows XP SP2, AutoPlay is enabled for removable drives also. This includes ZIP drives and USB mass storage devices. If you activate the settings disable AutoPlay, you can disable AutoPlay on a CD player, on removable media, on all players readers.

    When you set the option as options to disable automatic execution, it is set as default and no change is possible.

    However, in order to disable specific Autorun features in a selective way, you must change the NoDriveTypeAutoRun entry in one of the following subkeys in registry keys:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\policies\Explorer\

    The following table shows the settings for the NoDriveTypeAutoRun registry entry.

    Value

    Sense

    0x1 or 0x80

    Disables autoplay on drives of unknown type

    0x4

    Disables autoplay on removable drives

    0x8

    Registry warning:
    Sometimes, this problem is due to two Windows that have been corrupted registry entries. To resolve this problem, you must use the registry editor to delete the corrupted registry entries.
    However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

  • Connection 12 '' Macbook to Thunderbolt display does not work (USB - C for HDMI / Lightning)

    I have connected a retina 12 '' Macbook to a Thunderbolt display via two adapters, and no video is coming through.

    Here is what I use:

    1 USB - C for HDMI: (Apple USB - C to HDMI adapter)

    2 HDMI to Thunderbolt (Monoprice adapter)

    Any ideas what's happening? The Thunderbolt display is without a doubt, since power is to come via USB when I plug my phone directly on the back of the monitor. The Apple adapter works because I could try to connect directly to a LG monitor with HDMI ports.

    The present model 2015 MacBook 12 inch Retina does not support the Apple Thunderbolt display

    what I read.  The other models Apple Cinema can work if they are used with correct adapters

    as other brands. Some adapters support the audio, while others do. Note there is

    limits for the specifications of display supported; This can limit their usefulness if it is not better configured.

    Special adapters and cables can allow to configure some display options for use with the MacBook.

    The graphical support through MacBook, MacBook Air, MacBook Pro varies with the specifications.

    The absence of a Thunderbolt port, use of adapters to provide only what it can bear MacBook 12 plug-in software component.

    and the mini-display port cannot connect or transfer at frequencies Thunderbolt usage views. The

    cure should be taken as built-in support for this; If the adapters could carry signals. A new model

    could understand such an improvement; but there is nothing of this specification in the Apple Store again.

  • Update of the USB-TC01 Firmware

    I have a USB-TC01, and whenever I try to use it on my Windows 8 tablet it gives error-201168, with the text of 'Possible reason' doing this:

    "Firmware for this device is too old.

    Update the firmware for this device. »

    I get this error when you use LabVIEW 2011 so while trying to run the automatic test within MAX.  The unit currently has firmware version 1.0.0f1, and I found a page (https://decibel.ni.com/content/groups/tc01/blog/2011/05/23/ni-usb-tc01-101-firmware-update-now-avail... , indicating that he has a 1.0.1 version available, but ideally the download link no longer works.)  This unit works great on my Office Windows 7 in the Office last week, but now that I'm in the area I can't make it work.  I don't remember what version of NOR-DAQmx, I'm running on my desktop, but my Tablet has NEITHER-DAQmx 14.5, and I noticed that the only versions of DAQmx listed are 9.1 thanks to 9.9.  I can't imagine they took the features of future versions, but none of this makes no sense to me.

    Any suggestions?

    Edit: It seems that 14.5 DAQmx always supports the tc01s after checking the hardware compatibility list, so I don't know why the more recent editions are not listed on the download page for the driver for the tc01.  And it does not help my situation, where I assume that new versions of DAQmx will require an update of the firmware available to work with the tc01s.

    Hello Macraw83,

    In fact, updated the firmware of the device and DAQmx 14.5 and later version will seek this newer firmware.

    You can download the utily to update the firmware of your NI USB-TC01 from the following link:

  • How to make a USB-TC01 temperature data a global variable?

    Hi all!  I have a simple question (probably).  I bought the box USB-TC01 and with the software came a VI called LabVIEWTempLogger.  This VI reads a thermocouple voltage and internal conversions using DAQmx and a CYC edge to give a reading of simple temperature.  My problem is that I want to use this temperature in an another VI, then I want to make a global variable of temperature of LabVIEWTempLogger.  How to set a global variable such as temperature of LabVIEWTempLogger?  Thank you!

    You must get out of the recorder temperature VI the DAQ Assistant. Put it in a Subvi if you wish.

    Your main VI has some problems. The first fact a comparison is equal to the current temperature. Never make an equal comparison on a floating point number. Use in the range and force.

    The local 'Set Temp deg C' should be replaced by a wire from the Terminal. All local variables should be replaced by a wire. You can easily have the cable terminals from outside the main loop.

    Can't the difference in code in the States True and False when you read voltage.

    Don't use VISA bytes to the Serial Port. It's just bad style. You programmed it for a terminal character LF to get rid of fixed forward and set the number of bytes to read at a high number. Playback will wait until the stop character is detected and then automatically end.

    Finally, you have already created a world so I do not understand your questions about it.

  • 64 bit Windows7/8/8.1/10 USB drivers for Palm Desktop

    Thank you people much more to Aceeca.com (Palm OS Garnet NEW manufacturers), the USB drivers for Vista, Windows 7 and 8 Win 64 bit operating systems are available.  There are many users Palm Desktop 4.x strives also to the declaration.

    I have synced my TX my Vista64 laptop computer bits and Windows 8.1 HP spectrum X 2 hybrid successfully through my USB cable.

    The drivers are located here:

    Aceeca Driver Downloads

    (NOTE: as of today, 01/08/2016 Aceeca site to be down for 'construction'.)  Drivers can also be found here: http://www.palmdr.com/windows-7-64-bit-usb-drivers)

    Installation instructions for Windows 7 (from Aceeca) are included in the download.

    Basic instructions:

    1 download the drivers and extract them in the same folder.  Remember the folder that you extracted to.

    2. try to HotSync your device.  It will fail.

    3. open the Device Manager and look for the yellow Triangle next to the other "Acceca" or "'Palm device ' in the"Other devices"section."

    4. right click on the device and choose "Update driver software".

    5. choose "Browse my computer for software" and guide them to the folder that you extracted the drivers Aceeca.

    6 choose 'Next' in the driver and then file location window tell him 'Confidence always Aceeca Ltd. software', then click on the button "install".

    7. I received an error message (Vista64) who told me "the drivers have been installed, but the device could not be opened." I realized my TX had expired, and fell asleep.  I tried a HotSync and it worked!

    Good luck!

    NOTE: Palm Desktop 6.22 may only multimedia show and install.  Here's how to fix this:

    If Palm Desktop 6.2.2 shows only the media and installation, try this: right click on the shortcut for Palm Desktop, and then choose 'run as administrator '.  Other modules should appear.

    To Palm Desktop run as administrator every time in Windows 8 / 8.1:

    Close to Palm Desktop, if it is open.  (This is a very important thing to do when you use 6.2.2 - it has been known to lose data when a computer is shut down without closing the program!)

    Right click on the desktop icon of Palm in the metro screen, then choose "open file location".  You will now see the actual file for the shortcut.

    Right-click on the file "Palm Desktop" shortcut, then properties.  Now, choose the tab compatibility at the top.

    At the bottom of the Compatibility tab is a checkbox: "run this program as an administrator", click OK.

    Try to open the Palm Desktop, all parties must appear.  You can see a box opens when you close the program asking "did the program runs correctly.   I chose 'Yes', and it has been working fine since then!

    If you are using a much older PalmOS device and try using Palm Desktop 4.x, you will need this additional patch Pimlico Software:

    Palm HotSync configuration

    Forum member bobboffin has added this message:

    "After you try your first HotSync and failing (as expected) you may be unable to find any trace of the device in Device Manager, making the next step very difficult. It is me, and after some research, I discovered the following trick that allows Device Manager to display hidden and devices not present.

    Open Notepad and paste the following two lines are:

    Start devmgmt.msc

    Save it as SetDev.bat in My Documents.

    Open My Documents in Windows Explorer and double-click SetDev.bat. Device Manager opens.

    On the view menu, select Show hidden devices.

    You can now see in the other position of the device with a yellow triangle against it.

    You can now proceed to install the drivers according to the instructions.

    Has anyone tried installing the USB drivers for the 50g on Windows 8?

    Conn4x installed well but USB drivers comes. I tried all available troubleshooting options using the features of Windows 8 compatibility (XP, Vista and 7) and none of them worked.

    So I was wondering, maybe someone here may have already installed and could share some tips.

    Thank you

    I read messages in other forums indicating that the conn4x and the USB driver peut be installed.

    The post on the forum indicated that Windows 8 comes pre-configured with the possibility for signed drivers enabledapplication.

    In order to install the USB driver, signed driver enforcement must be disabled.
