Hello @Fausto, Thank you very much for your help. I was able to connect the C# program with the device and successfully read the data. I really appreciate your assistance. Best regards, Ali

Greetings, I am working on a program to read data from my MCC DT9874 Series device. I have installed the MEASURpoint Software and obtained all the necessary files and drivers. In the IVI Foundation folder, I found the examples for C#. After switching the project to x86 in debug mode, the program runs without issues. However, when I try to connect to the device, I need to enter a VISA Connect String. Based on my research, I found that the format should be: USB[board]::manufacturer ID::model code::serial number[::USB interface number][::INSTR] Using this format with the relevant details, I attempted to establish a connection but without success. I receive the error message: Initialize Failed: "Could not create instance of VISA-COM Global Resource Manager Component. Make sure it is installed properly." It's worth noting that I was able to connect to the device using the QuickDAQ program, so the drivers should be correctly installed. Which installation is being referred to in this error message? Is it the MEASURpoint Software, or do I need to install something additional? As a student, I am currently stuck and would appreciate any help you can provide. Thank you for your assistance!

hey, I have now managed to get the program running. It turned out that the issue was due to selecting "Any CPU" instead of the correct "x86" during debugging. Now, I have a new problem: connecting to the device. The connection to the device works with the Quick DAQ program (Connection via USB), so the drivers are correctly installed. In the C# example program, I need to enter a VISA Connect String. What should I enter here to ensure a connection with USB to the device? I have tried using the Vendor ID (VID), Product ID (PID), and the serial number, as I read that this should work, but it didn't. Here are the device details: VID: 0x0867 PID: 0x7198 I hope you can help me with this.

Hello @Fausto, Thank you for your previous response. I have now reinstalled everything on another computer (Windows 10) and this time it looks correct. I have the Visual Studio file and everything seems fine so far. I wanted to test the C# example program that was in the Visual Studio folder. Initially, there were errors because the necessary references were not specified. After I added Ivi.Driver.Interop.dll from the Primary Interop Assemblies folder (IVI Foundation\IVI\Bin\Primary Interop Assemblies) to the project, most of the errors were resolved. Another problem was that I did not have the target version .NET Framework 4.0. When I tried to install it, it failed because I already have a higher version installed. Therefore, I tried with .NET Framework 4.8, and that error was also resolved. Now, when running the file, I encountered another error and this time I don't know how to fix it. The error is: The "ResolveComReference" task returned false but did not log an error. DtxMeasurementApp 2005 Could this be because I am using .NET Framework 4.8 instead of .NET Framework 4.0? I also found a potential cause of the error in the references: there is an entry named IviDriverLib with an exclamation mark (see screenshot). However, I do not have a file with this name and cannot add it. Otherwise, I can't think of any other reason for this issue. I hope you can help me. Although I am currently using Windows 10, will it also work on Windows 11? Best regards, Alibumaye

Hello @Fausto, Thank you for your previous response. I use Windows 11 on my computer. Does the software work for Windows 11? Best regards, Alibumaye

Hello @Fausto, Thank you for your previous response. I have installed the MEASURpoint software version 3.3.3, but I could not find the specified folder “IVI Foundation\IVI\Drivers\DtxMeasurement\Examples\Visual Studio” (You can see it on the Screenshot). Instead, only a folder named “Data Translation MEASURpoint Software” was created. Here are the details: Installed Software: MEASURpoint Software Version 3.3.3 Installation Folder: “Data Translation MEASURpoint Software” Contents of the Folder: Several files and subfolders, including a file named “setup.exe.” I have a few specific questions: Reinstallation: Should I delete all previous installations of QuickDAQ software and the IVI folder, and then reinstall the MEASURpoint software? Setup File: Should I run the “setup.exe” file in the “Data Translation MEASURpoint Software” folder? If so, what steps should I follow afterward to ensure that all necessary drivers and examples are correctly installed? Example Codes: Is there a specific path or an alternative download link to obtain the Visual Studio example codes for the MCC DT9874 device? I want to ensure that I have the correct example codes and the necessary drivers for programming with the MCC DT9874 MEASURpoint device. Any additional guidance or step-by-step instructions would be very helpful. Thank you for your support! Best regards, Alibumaye

Dear [Support Team], Thank you for your previous response. I appreciate your guidance. However, I am still struggling to locate the example codes for the MCC DT9874 MEASURpoint device within the QuickDAQ software installation. Could you please provide me with a detailed step-by-step guide outlining the necessary steps to find these example codes and to ensure the proper setup for programming with the device? I have already installed the MEASURpoint software that you mentioned but i could not find any examples for Visual Studio.NET. Finding the Example Codes: Which path should I check in the installation directory of the MEASURpoint software to find the example codes for the MCC DT9874 MEASURpoint device? Are there specific folders or files that I need to access to retrieve the example codes? Required Drivers and References: You mentioned using existing Visual Studio.NET examples. Could you please clarify where these examples are located within the MEASURpoint software installation? Additionally, what drivers are needed to use the MCC DT9874 MEASURpoint device programmatically? Are there specific libraries or references required? Programming Guidance: Once I have access to the example codes and necessary drivers/references, are there any specific configuration steps I need to take in my development environment to ensure compatibility and successful programming? Your detailed guidance and clarification on these points will be immensely helpful in my efforts to utilize the MCC DT9874 MEASURpoint device programmatically. Thank you for your attention and support. Best regards, Ali

Dear Forum Members, I am interested in acquiring data from the MCC DT9874 Series device within a program. My primary goal is to interface with the device programmatically to read data. Could you please confirm the compatibility of the MCC DT9874 Series device with InstaCal and the Universal Library (UL) for programmatic data acquisition? I am aware that InstaCal is recommended for device configuration, but I would like to confirm if it is compatible with the MCC DT9874 Series device. Additionally, I am interested in using the Universal Library for programmatic data acquisition, preferably in C++ or C# since I have not found support for Python. I have come across older templates and examples dating back to 2005, but I am wondering if there is a more recent version available. Furthermore, I have encountered issues with missing or non-functional references in these older resources. Is there a possibility to access the device's data programmatically through a serial connection, even though there is no official support for Python? Assuming I have the necessary commands and knowledge for serial communication, would it be feasible to achieve data acquisition in Python? As a student your insights and guidance on these matters would be immensely helpful to me. Thank you for your attention and support. Note: The Software QuickDAQ is working with the device. you can se on the Screenshots the examples that i already have for c# and c++ but have problems to work with that Best regards,

Me again :) Since c++ examples are available, could you please provide any useful links or resources for accessing these examples? I appreciate your assistance.

Thank you for the quick response. I should have asked directly, then i could have saved myself some research.

Hello everyone, I hope you're all doing well. As a student, I'm currently facing challenges in understanding and utilizing the mcculw library for my MCC DT98700 data acquisition device with Python. I'm reaching out to seek guidance and clarification regarding its compatibility and functionality. I've installed the mcculw library, but I'm struggling to navigate it effectively. At this stage, I'm primarily interested in determining whether my device supports my objectives, specifically, if I can read data from it using Python. The full product name of my device is DT9874 32T-16R-00V, as labeled on the device itself (for more info look uploaded Images). My intention is to use it for temperature measurement. Could someone please provide insight into whether my device supports data retrieval via Python and how I can accomplish this? Additionally, I'm keen to learn how to correctly configure the mcculw library for my device and any resources or tutorials that could aid in my understanding. Question if Python on device is possible: I've already installed the Python library for my DT98700 device, but I'm unsure about what value to enter for the "Board Number" to correctly address the device. I've tried looking through the documentation, but it's not entirely clear to me. Maybe some examples with explanations would be helpful. Thank you very much for your time and assistance!
