Got the dreaded 32701 error today and have tried everything to get a connection but no joy.I have a Davis Vue with the serial to usb datalogger. I know this is not a Cumulus problem but i'm just wondering what are the steps i should take to get my station back in working order. Maybe i'm missing something. Thanks in advance,

Mike

I get the same error now and then, I just jump in to the backup folder and replace the data from last Cumulus start up and reboot the computer.


Rebooting is the only way I have found that the Station will reconnect.

No big deal

This error happens at least once per day on my system.
My "new" solution is to close Cumulus. Open the devices and Disable the Silicon Labs CP210x then Enable it.
Restart Cumulus and it continues by downloading from the virtual port.

I have turned off the Cumulus Restart if unplugged or data stops as these options do not seem to be doing anything.

The last 32701 error, 35 minutes ago, the Error light was flashing and the log window gave the times for what I assume are retries.

The 32701 errors appear to be more frequent with recent 1.9.2 builds.

The code in Cumulus hasn't changed for a very long time, and it has been using the same version of the Davis DLL (which handles the communication) for a couple of years now. If it's only an issue with Cumulus and no other software, you would expect the DLL provided by Davis to work OK with their own software - if not better than the 'write your own communication code' software. Then again, the VSP code isn't actually written by Davis.


The 'restart if unplugged' option only applies to USB stations i.e. stations where Cumulus drives them directly via USB and hence receives 'unplugged' notifications from Windows. This does not apply to stations driven via virtual serial ports as Cumulus is not using a USB protocol and does not receive any 'unplugged' notifications.

The 'data stopped' code checks whether any data has been received in the last minute. If it has, it doesn't restart.

But the fact that you have to disable/enable the VSP code means that these options wouldn't be any use to you anyway, and there's nothing that can be done about this from Cumulus.

Ever since I installed the Davis Vantage Vue and Cumulus I have been getting the "data stopped" error at least once if not three times a day.
Initially, I had the Station options "Restart if unplugged" and "Restart if data stops" enabled. These setting gave me a pop-up window indicating the error.
After Steve's report these options work on USB stations only, I disabled them.
Interestingly, if the settings are set and an error occurs, there are no entries in the error log.

Then the only notification there was a problem was the flashing error light if Cumulus was not minimized. The error log shows when the error started and the latest error time.

My solution at the time was to shut down Cumulus and Disable and Enable the Silicon Labs VP then restart Cumulus.

To say the least this process was frustrating.

In an attempt to find a cure for my computer's slow start up, I completely removed my AVG Internet Security software and installed Microsoft Security Essentials.

Wonder of wonders. There have been no 32701 errors for a week.
For some reason AVG Internet Security was either monitoring or managing the VP.

This may or may not apply to others getting the 32701 erro.

Carl, I have been running Cumulus on a Windows 7 32-bit computer for more than two years. The weather station (a Vantage Pro2) connects to the computer via the WeatherLink USB adapter and a USB cable. Inside the computer, the USB port is converted to a serial port via the Silicon Lab CP210x USB to UART Bridge VCP drivers. The Virtual VP software then contacts the serial port and make the data from the weather station available to two weather software (Cumulus and WD) - both software get their data through the 'simulated' serial ports.

A similar installation is now being tested on a new computer running under Windows 7 64-bit.

The only times I got the error '32701' was when I assigned Cumulus to the wrong port - otherwise, I have never encountered the error.

My computer is running all the time - neither the screen nor the computer are allowed to go to sleep. Also, for the Silicon Lab CP210x USB to UART Bridge VCP drivers, the power management option to 'allow the computer to turn off this device to save power' has been deactivated.

Oh, I forgot to mentioned - both computers are running the latest version of AVG Internet Security 2012 - the new computer is also running Microsoft Security Essentials, so far without conflict (MSE installed itself during one of those multiple updates).

Good morning Ray:
Other than using a Vantage Vue and Win 7 x64, my settings would match yours.

I was running AVG IS 2012 on three computers, a 32bit XP Graphics Workstation, a 32 bit Vista office computer and a 64bit Windows 7 Graphics Workstation. On the 32 bit systems AVG IS runs without too much interference, but on the 64 bit Workstation it was a real slug. That was why I decided to try a different security system.

The Vantage Vue is connected to the 64bit Workstation and as soon as I switched Internet security programmes, Cumulus operated without the 32701 error.

Therefore, my observation that the Anti-virus system may have been interfering.

Carl

Indeed Carl, too many of those safety/security software are getting so 'bloated' they are slowing down even powerful computers - what is the purpose of getting a faster/more powerful computer/CPU if the software designers are only going to add useless stuff to their software and make the computer run at a 'turtle' pace!

It is quite odd that AVG would cause such situation of either preventing the 'VantagePro.dll' from communicating with the CP210x USB to UART Bridge VCP drivers or preventing the CP210x USB to UART Bridge VCP drivers from communicating with the USB port (and the WeatherLink adapter)!

Since you have managed to re-establish communications using Microsoft Security Essentials there is no need to look for something else - and from my readings, Microsoft Security Essentials is well rated.

I think i may need to add my two pennies worth in here lol

I started using Cumulus a few weeks ago (on my older PC) although it was quad core, 64bit, win 7 etc .. i never had a single -32701 error.
I purchased a new one a few days ago, i5 win7 etc .. and now i'm getting the -32701 about twice a day at random intervals. But the weird thing is, my external harddrive also stops too. It won't spin up when i go to access the files. If i unplug the USB's i don't hear the 'nuh-uh' sound, or when i plug them back in. I have to reboot the computer to get them both working. But my USB mouse and keyboard continue to work ?
I've swapped all the USB's around and the problem still persists. The thing that annoys me most, is the fact that i never had this problem on my old PC, which isn't much different from the one i have now. So in my view, i don't see how the Silicon Labs bridge can be the problem.

Have you install all the required drivers supplied by the mainboard (motherboard) producing company - I am not writing about the Microsoft drivers but about the drivers that are specific for the mainboard inside your computer?

I am in the process of setting up three new computers, two with an Intel Core i5-2500 CPU on a MSI MSI P67A-GD65 (B3) mainboard and one with an Intel Dual Core E6600 CPU on a MSI G41M-P28 mainboard. All the mainboards came with a CD containing the required drivers for the CPU as well as all the ports on the mainboard. If the drivers are not installed once Windows has been installed, then most of the expected functions and ports are deactivated.

My assumption is that a USB driver might not have been installed on your computer. Even without a USB driver, the keyboard and the mouse will operate.

You could check the Windows 'Device Manager' to ensure that all the required drivers have been installed...

The base unit was already preasembled, just like the one before. That's all done in the shop.

Is that '9600' the baud rate? Because i see a 19200 in there, and i thought that was the default baud rate of the Vantage Vue?

But, but, that does not mean that everything is all right, that all the drivers have been installed and/or updated...

A shop/store can only install what is on their 'master' OEM installation disk ... and the people in those shops/stores are certainly are not going to test all the components of a computer for more than just a few minutes... For a shop/store, time is money - if the time required to install and test an operating system (software) can be reduced, even by a few minutes, it will be reduced ... at the expense of the buying/paying customer...

But the external harddrive, my outdoor cam, the weather software wouldn't work at all if that was the case. I've swapped all the USB connections around to test them, they still work but then the error will appear at some random time during the day or night. I can 100% guarantee you that the software for the motherboard is working and up to date.

You wrote in a previous message:
So, it is almost obvious to me that there is something wrong with the control of the USB ports - there is no reason why the USB ports should all go down at all (or stop operating) and certainly not at the same time!
The mainboard does not use software per se, it uses drivers for its different components. How can you be 100% sure that the operating system/software (which would most likely be Microsoft Windows 7 64-bit) and one of the drivers are not, under special conditions, conflicting with each others and disabling the USB ports?

Previously I had posted that Microsoft Security Essentials cleared up the 32701 error, but that is not the case. MSE just made the computer faster.

The 32701 errors are still there and at random times and yes, all of the motherboard drivers are installed. All other USB devices work properly, Wacom tablet, mouse, card writer, pen reader, Kindle, etc.

Steve states Cumulus just reads the Davis DLL, then I can only assume the Davis DLL is not stable on Windows 7 x64 because it does not matter which version of the Sil Labs VP is installed. I have installed the versions from the Davis site plus the versions from the Sil Labs site and still get the 32701 error.
