Re: Pi Datalink 2013 Install Kit

PathWave Advanced Design System (ADS) 2021 Datalink is an add-on that enables engineers to process simulation data in the Data Display environment using customizable Python scripts. Datalink consists of a set of ADS and Python functions which, when paired together, enable automatic data transfer and script execution. The scripts are invoked using a standard Data Display equation object or a schematic based MeasEqn object, and data can be passed through this equation as well. Datalink includes a full, standalone Python 3 install which is used to execute the scripts. Adding Python to Data Display enables advanced functionality such as instrument connectivity, 3D plotting, and contour generation. Several example applications and customizable scripts are included as part of the install and the example workspaces, Datalink_Basics_wrk and Plot_Various_Meas_LP_Data_Using_Datalink_wrk. It is not necessary for the user to know how to code in Python to take advantage of these capabilities.
I have Mids installed, but the "Click this DataLink" links fall over and die. When clicking on them, I get the expected "Open mids_build.mxd" prompt with Mids Reborn as the default choice, but when I accept this, I get the error "The feature you are trying to use is on a network resource that is unavailable", with a file browse pointing to the folder where the install file was located. Selecting 'Browse' and picking the install file produces the error "The file xxxxxxx is not a valid installation package for the product MidsReborn" and then goes through three separate window closures to exit the attempt at import.
Initially, I thought the problem might be that the installation file was "MRB Setup.msi", while the file dialog was looking for "MRB_setup.msi", but that shouldn't make a difference once the file was selected. Attempting to repair the installation failed; with 'MRB Setup.msi' not producing a UAC prompt requesting permission, and therefore failing for lack of rights. Uninstalling completely worked, then downloading a new copy of the MSI file and installing (default location) worked, and the program will open builds from my hard drive normally, as well as the 'copy and paste this text' block from builds in the forums, but still produced the same failure to recognize the installer as a valid install package when I try to click on the "Click this DataLink" links.
Working a hunch, I uninstalled Mids Reborn once more and reinstalled it, selecting "Only for me" instead of 'for everyone" during the installation, and after starting up following installation, I clicked on a "Click on this DataLink" link in the forums, and the build opened correctly in Mids. Somewhere in the install for all users on the computer (not really needed, since I'm the only user), it fails to establish the proper setup to open the forum data links. It looks as if a workaround -- if you have more than one person using the computer with Mids Reborn -- is to make separate individual installs for each user, but I have not verified this.
While the creation and design changes of Crystal reports (.rptfiles) require the full Crystal Reports software, you canlet other PCs view, print, and export these reports by installingDataLink Viewer.
You may be prompted to install some of the prerequisites listed on the AquaCalc DataLink 3 Install webpage. DataLink needs several components provided by Microsoft. If you do not already have these components, the setup program will download and install them automatically.
The AquaCalc Pro Analyzer spreadsheets can be downloaded separately, it is not necessary to download and install the entire DataLink program if changes have been made only to the AquaCalc Analyzer.
The AquaCalc DataLink software is used to download, review and print reports of section discharge measurements from the AquaCalc line of discharge measurement devices. This software can be installed for free from our website.
You can then choose which measurements to download and where to store them. You can then delete measurements from within DataLink and display table and graphs of your downloaded section discharge measurements.
We have replacement parts and cables for the AquaCalc line of stream flow computers including the Digital Pygmy Magnetic Head retro fit your old Pygmy Current Meter with a new digital magnetic sensor.
The remote console data seems to be always realtime, so there is obviously realtime communication between the Cerbo and the network so where is the fault to be looked for? It is the same problem whether I open the VRM Portal in Chrome, Edge (Windows 10 laptop) or Android on my phone.
Thanks for that idea. I don't know if I am experiencing slow wifi network speeds. I would have though that all the Tik Tok and YouTube vids that the kids watch (alright, me as well) would be higher traffic than the VRM but the problem persists on a school day when the network is very quiet.
Is it helpful to think about the different things that are going on here? (apols if the below seems simplistic)
1. when you view the remote console in a web browser, depending on configuration, but mostly, you are seeing data which is sent over your local area network, i.e. the browser is fetching data from the Cerbo over your LAN, there's no internet involved. Hence, it's always just there.
2. When viewing the VRM, when it's showing 'realtime' data, it is fetching lots of data from the Cerbo transmitted via the internet to the VRM, i.e. it is uploading data over the internet. Your web browser then downloads the data processed by the VRM.
The (potentially) big difference with viewing the VRM and watching Youtube vids is that when viewing Youtube vids generally there is very little uploading going on (just a bit of browser activity with cookies and the like). Whereas, 'realtime' VRM viewing requires lots of uploading of the realtime data from your Cerbo. Depending on your internet connection, uploading can be a bottleneck. Sometimes, though, the problem is with Victron's data processing of uploaded data - that's what @kevgermany is referring to above.
It may be that your internet connection is the problem. For example, even with an 80-20 fibre-to-the-premises internet connection (80Mbps download - 20Mbps upload) I sometimes see delay in the VRM being able to display 'realtime' data. Now, if I had a cheapo non-fibre broadband deal, I'd expect upload to be a bit flaky.
Also, maybe your router is a bottleneck - again, if it's a cheapo broadband-deal-router it may have less uploading capability. Maybe worth checking with your ISP's recommended speed checking service and see what your upload spec is?
I don't know what upload speed is required - probably not that much. But the issue will also be about how stable the upload connection is. Often, broadband speed checking services show you the best available speed over a period of time, but don't show how intermittent the service is.
If you had a 5g smartphone (and decent coverage), you could try connecting the Cerbo via wifi to the phone's internet connection, for the uploading of data.
Although @nickdb is correct to advise disabling node red (presume he means to disable Venus OS Large on the VRM side menu?), some people have built complex node red based dashboards, including using memory, which could be all LAN based and mimic what the VRM does. But that is a v complex, time consuming thing - example here

As I understand it, this 'Too Busy' message is internally generated by the GX, and happens when it gets preoccupied with it's own calculations and comms to the other connected devices. It deliberately stops talking to VRM until it catches up with it's own priorities. And yours can't catch up.
I'd look there for the issue. Maybe you have a lot of devices hanging off the Cerbo, and could pull them one-by-one to see which one might be causing the GX grief. Maybe also something like a missing CAN terminator?
@usernamepasswordbs In support of this point, I have an almost 5-year old single processor CCGX on a system 6000kms away that I manage. It is remote, off-grid, has a RJ45 connection to a 3G modem. The rconsole can be sluggish at best and screen very refresh variable. The same error occured and the solution was to keep the CCGX monitor on a static screen, I do the same for the remote rconsole before closing it as the process may otherwise still continue running even after closing it. (Even on the dual cpu cerbo I typically disable the wifi hotspot and bluetooth, both from a security perspective and given unwanted comms processes can take up a lot of resources.) A bad (loose) connector resulting in errors or missing terminator as mentioned are all worth exploring. Lastly, maybe experiment with the VRM upload interval too if it is set at 1 min.
As you can see, the actual message is (to repeat this thread title) "Installation too busy realtime data link disabled". Last Dec @nickdb said on this very same topic: "If the gx has lost comms for some reason and is busy sending logs back, it can also show this error until caught up."
So, I installed the flash on a usb stick as recommended by Nickdb, unplugged everything from the Cerbo, put the stick in and reconnected the power. I waited a while then unplugged and replugged the power to reboot as per instructions, then realised I hadn't taken out the usb stick! I waited again, then unplugged, removed usb and rebooted a second time.
I had connection issues and almost brought the Cerbo and a car battery into the house (like I did when I first installed the system) to plug in network cable to do the internet password and all that. I could access the Cerbo via Victron connect with my phone so I played around with a few network settings but to no avail.
After several failures to connect to a network using my phone next to the Cerbo, going back and forth to the house and trying on the laptop, then, suddenly, it did connect and I had realtime data on the dashboard.
