STILL CAN NOT CONNECT V2


David Eckhardt 2020/12/08 20:40

Here is the first activity that I can activate:
[image: image.png]
On clicking on COM1, this is the error message I get:
[image: image.png]

In NANO-SAVER 3.8, all I get is "NOT CONNECTED"

Any ideas? I've run out of ideas. I have two USB cables, but are good.
HELP!

Yes, the recommended USB driver is installed.

David can you see com port number in Device Manager ,check when you connect VNA to computer,hope it helps ,Dave 73

Here is what Device Manager sees for USB controllers:
[image: image.png]
How should the proper controller show in the list?

David ,stay on that page ,connect and disconnect usb cable to computer you should see which usb device it is ,then you can right click the device and check comm port number ,it looks like it’s USB to UART device ,bit late now but I’ll check tomorrow,Dave

David Eckhardt 2020/12/08 23:47

How can I confirm the USB controller is properly installed?

I have an AMD 6-core processor running at 3.6 GHz. Is all of this
compatible with AMD processors? I have no problems with the pre-V2 NANOs.

Did you plug in and switch on tge device before fire up qt??

Did you try to click on refresh?

Did you check in device manager if driver installed and on what comport number
the device is found?

Mine appears in USB Controllers as "USB to UART adaptor" and opens up a
new COM port 9. This unit is a V2Plus4.

This is the driver installer I used

Yes, the device was on before launching either Saver or QT.

Did you try to click on refresh?
Yes, I clicked refresh. Nothing happened. I've also tried manually
entering com1 through com10 with no results.

Did you check in device manager if driver installed and on what comport
number the device is found?
How should the driver show itself in device manager? When I click on the
driver downloaded info, it goes through the install as expected and I see
it under Program Files (86). There is an install there for both 32 and 64
bit. When I click on that, all I get is a very, extremely short screen
flash with no additional information. I doubt it is properly installing.

All I see is COM1 whether the NANO is on or off. I do not detect the
presence of the NANO at all.

Are you going directly into a USB port or a hub?

Is it a usb 3.0 or 2.0 port?

Have you tried disconnection of all other usb devices and restarting to eliminate port conflicts?

You should see it show up in device manager as a *serial port* (not
under the USB devices - although it will also show up there).

If you plug it in, and the device manager screens don't change (and you
don't hear the "chimes") then it's not recognizing it. That points to
USB device driver issues (assuming that the box itself is working, and
the cables are good, and the USB connector on the board didn't get damaged).

I assume you rebooted after installing the USB driver (that's part of
the driver install process usually).


There's a note on the Windows answers site:


https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/issues-with-usb-to-serial-on-windows-10/72b7d5e8-865b-4fc4-bc48-e6a13eea2f7e


Go to the Device Manager and type “Device Manager” in the lower left
corner of the screen.

Locate the USB to Serial Converter Settings. After plugging a USB device
into your machine, expand the “Universal Serial Bus controllers” list in
Device Manager. Click on the “USB Serial Converter” and open the USB
Serial Converter properties.
Enable the VCP Driver loading by opening the “Advanced” tab within the
USB Serial Converter properties. Make sure the “Load VCP” option is
enabled and then click OK to load the VCP.
Re-connect the device. Unplug the USB device and re-connect it to your
computer. At this time, Windows 10 should recognize the device and load
the Virtual Com Port Driver.

This appears to be similar

I haven't been following this thread, but has he ruled out any subtle win10 file corruption, by using sfc /scannow at the Powershell (Admin) command prompt?

Ken Sejkora 2020/12/09 04:26

Hi Dave,

Going out on a limb here.  One of the other members of this group reported that on his nanoVNA V2 he found the USB signal lines were swapped between the UART chip and USB socket.  He was able to cut, swap, and resolder the two lines on the circuit board and restore functionality.  I don't know if swapped data lines would result in the device not being seen, but it might be worth checking.

Take a look at the message thread associated with Message #735.

Good Luck --  Ken, WB ØOCV

Siegfried Jackstien 2020/12/09 14:53

if the device is found in windows (say as com9 or com 32) then the usb
lines are sure not swapped

otherwise windows would not show it as a valid comport number

and .. if found in windows (say above example com32) ... it will show in
saver, nanovna_app ... or vna_qt also as com 32

maybe some fancy security setings in his windows (or an antivir soft or
similar) was causing the driver not to be installed correct??

here it worked right out of the box ... on a core2duo with win7 and on
an atom tablet with win10 ... with all 3 soft ... and with 3 different
analyzers (i have a v2, a v2plus and a plus4)

Hi Dave,

I ran onto the same thing.  As it turns out it's a pretty easy fix.  The following from my notes:

"Activating the NanoVNA and NanoVNA Saver (also known as `SAVER`)"

Powering up the NanoVNA and NanoVNA Saver software can be a little troublesome. The major issue is getting a Windows PC to connect to the NanoVNA.

There’s a little trick to get the PC and the NanoVNA reliably connected via a USB cable. Initially DO NOT POWER-UP the NanoVNA.
--------------------------------------------------------------------------------------------------------------------------------------------------

*First* , on the PC (Win10, in this case), launch NanoVNA Saver v3.7 or v3.8 (preferred) and verify that the driver load screen appears followed by the
graphic screen.

*Next* , connect the USB cable to the PC then to the NanoVNA *BUT DO NOT POWER UP THE NanoVNA*. *SAVER* will show an empty Serial port
dialog box. (which is what you probably noticed)

*Now* , power-up the NanoVNA. You should see the default NanoVNA graphic screen on the NanoVNA.

On the PC’s *SAVER* screen; the Serial port control box should be ‘blank’. Click the *Rescan* button and an available serial port should appear.
For example, “ *COM8 (S-A-A-2)* ” or similar should appear in the Com box. (it's available but NOT connected)

In the *SAVER* application, click “ *Connect to device* ”. Take a moment and look back at the *NanoVNA screen.* It should change from graphical display to a
'connect status screen' showing the installed NanoVNA version number and “ *USB MODE* ”.

The PC graphical screen should now be active and ready to accept configuration commands. SAVER will probably display the previous powered up
state and the graphic charts should be active. The displayed data and graphics sections are just plots from the NanoVNA and are not valid.  Just ignore the
traces BUT mentally note that uncalibrated traces are displayed.

The very top line on the *NanoVNA Saver screen* will indicate the version number, mode, date/time and current graphical plots.

For example, the very top line on Saver might show something like:

NanoVNA Saver 0.3.8 (Sweep: 2020-12-11 17:04:55 @ 101 points)

As mentioned earlier, the graphic windows on the right will have erroneous plots but that’s normal.  They just haven't been updated. Also, the sweep text
data sections will display old data.

The system is now ready for you input and operation.  You might want to run through this procedure a few times so that it's embedded in your head.

Enjoy,

Larry, K7JQL
