    DAQman got a reaction from Gislain Tefeu Fotsing in MCC 128: Voltage Measurement DAQ HAT   
    The MCC 128 is a multiplexed board, which means the input shares time with a single A/D converter chip. Using a single channel is the only way to get 10us timing; otherwise, the time between each channel is 10us.

    DAQman got a reaction from JaxTech in DaqView Data Acquisition File Conversion Types   
    Personal DaqView does not convert to a *.CSV file. As mentioned previously, the nearest file type is ASCII text. The software is discussed in Chapter 4 of the user manual. 
    For direct logging to *.CSV, consider upgrading to the DASYLab software.

    The MCC Linux driver runs in the user space. We use the libusb library to communicate with our devices. I think you need only to install uldaq inside the docker container.

    DAQman got a reaction from JaxTech in DaqView Data Acquisition File Conversion Types   
    For the conversion process to work, each IOtech BIN file must have an accompanying DSC file. The ASCII Text format is the closest to a CSV file.  It uses a tab, not a comma, as the delimiter.
    DIAdem, DADiSP, DASYLab, MATLAB, and Snap-Master are third-party software packages.
    WAV are sound files.
    PostView binary does no conversion.
    UFF is a universal format supported by third-party software like sound and vibration analysis.

    The link you provided downloads our DAQ Software CD. The programming support is added when you install InstaCal and can be found in ...\Public\Documents\Measurement Computing\DAQ\C\.
    I've zipped the *.h and  *.lib files and attached them below for convenience.

    DAQman got a reaction from gfrigo in Upgrading a DASYLab License-Will Worksheets transfer?   
    Although we label it an upgrade, it's a complete installation. The newer version gets installed in a separate folder, and it is possible to have multiple copies.
    I suspect you have either Windows XP or 7 running DASYLab 11.0 FULL. If you want to update this PC, I recommend DASYLab 13 because it was the last version to work with XP. 
    A DASYLab 2022 serial number can be used to install DASYLab 13 (or 2016 and 2020), but not vice versa. DASYLab 2022 is incompatible with Windows XP or 7. Older versions are archived here. 
    Your older worksheets are forward compatible, but once saved in the new version cannot be used with older software.

    DAQman got a reaction from Creation Test Solutions in Trying To Config Two USB-1024LS in System (Using Universal Library)   
    VB6 examples are included with the InstaCal installation from the MCC DAQ Software CD. The typical location is ..\Public\Documents\Measurement Computing\DAQ\VBWIN\. The easiest way to augment your program would be to create a BoardNum1 and BoardNum2 variable and assign them the board numbers assigned by InstaCal.  Then, all you have to do is duplicate the various functions, like cbDConfigPort and DOut, DIn, DBitOut, or DBitIn that you may be using.

    The Steinhart–Hart linear approximation used by the USB-TEMP is accurate only over a limited range. Measuring temperatures above 120 degrees C is not recommended or supported.

    DAQman got a reaction from kseidl3 in MCC USB-205 Sampling   
    There is no sample-hold circuit before the analog inputs. The time skew from channel to channel is the inverse of the aggregate rate, 500k or 2us. It's more noticeable at lower rates. For instance, sampling four channels at 1000 S/s is 1 / 4000 or 250us. However, this can be good because it allows the channel more time to settle down before the measurement.

    Use the Signal Adaptation module set to Linear Interpolation. Connect the faster channel to input zero and it will adjust the slower USB-TC data stream to match it.

    You could have the thermocouple wired backward. That would explain the temperature drop when heat is applied.

    Now that you have installed DAQami on Windows 11, you must update InstaCal, too. Run the following installation, and then try DAQami again.

    DAQman got a reaction from EKT in How to upgrade the USB-1608G firmware?   
    If the USB-1608G is plugged in, InstaCal should automatically detect it when started. If you've started InstaCal before installing the device, hit the refresh button or restart InstaCal. If it is not found, I encourage you to try another USB port or even another computer. If a second computer has the same issue, it's probably defective.

    DAQman got a reaction from dodge_neon in ERB24 'No Error' stopping Time Control measurement in DASYLab   
    The USB-ERB24 can be susceptible to electrical and magnetic noise -RFI and EMI. If the USB cable is close to equipment that may radiate noise, reposition it elsewhere. Also, get a USB cable with ferrite filters like this: https://www.amazon.com/Tripp-Lite-Hi-Speed-Ferrite-U023-003/dp/B008VOPCGY/. The ferrite on both ends absorbs high-frequency noise and will help.

    DAQman got a reaction from Anatoliy in USB-1602HS-2AO not recognized by PC (Win11)   
    You must run InstaCal with the USB-1608HS-2AO so that it is added to the board list. When InstaCal is closed, it creates a file that LabVIEW reads, which is read once it is first started. So, always close LabVIEW before making changes to InstaCal, and always close InstaCal before starting LabVIEW. If you do this and LabVIEW cannot find the device, check your computer for duplicate copies of our files. Check your whole system for cb.cfg, cbw32.dll and cbw64.dll. The correct locations for these are:
    C:\ProgramData\Measurement Computing\DAQ\cb.cfg
    C:\Program Files (x86)\Measurement Computing\DAQ\cbw32.dll
    C:\Program Files (x86)\Measurement Computing\DAQ\cbw64.dll
    If you find files in other folders, delete them. 
    Regarding the TracerDAQ error, it uses DirectX9, and the error typically means your video card is unable to run DirectX.

    DAQman got a reaction from OscarP in Voltage not 0 in analog inputs (USB 201)   
    You can test the input (CH0) by connecting it over to the +V pin, which is +5 volt signal. Then connect the input to the ground (AGND) and it should read close to zero. Assuming this all work, connect your sensor's -U to AGND and +S to the input.

    DAQami cannot redirect the value from an analog input to an output. Instead, consider the DASYLab software, which can. If you have C or Python programming skills, you could do it using our Universal Library API. LabVIEW is another possibility.

    DAQman got a reaction from Vasanthakumar in USB-CTR08: High-speed counter/timer device with eight counter I/O   
    The USB-2416-4AO (and AI-EXP32) inputs can be individually set to either differential or single-ended. However, the device has only one A/D converter, which is shared among the channels. Because of this, the measurements are not truly simultaneous. For example, if the sample rate is 100 Hz, the gap from channel to channel is 10ms.
