P275 FM Analyzer / Re: Unable to install on Win 11
« Last post by Jan on July 12, 2026, 09:41:10 am »
You don't mention which version of the P275 FM Analyzer you have, so I'll answer in general.

We're not aware of any compatibility issues with Windows 11. We use Windows 11 ourselves and all of our USB products communicate in the same way. The driver is included with Windows as standard, or Windows installs it itself. There is no need to install the driver manually.

The virtual COM port is only present while the analyzer is connected and powered on. This is normal Windows behavior, regardless of the Windows version. (Windows remembers the previously assigned COM port number, but it is only available while the device is connected.)

Could you please check the following?
  • Is the analyzer powered on when you connect it? Windows only creates the COM port while the device is connected and powered. In other words, is the power from the USB cable working? If not, the USB cable or port on the PC is faulty.
  • Does anything new appear in Windows Device Manager after connecting the analyzer? Please check both Ports (COM & LPT) and Universal Serial Bus controllers. If you see an Unknown device or a device with a yellow exclamation mark, please let us know.
  • Please try a different USB cable or a cable supplied with the device (if this is that case).
  • If possible, also try a different USB port (preferably directly on the laptop, not through a USB hub).
  • If you have another Windows PC available, please check whether the analyzer is detected there.

If nothing at all changes in Device Manager when the analyzer is connected or disconnected, Windows is not detecting the USB device at all. In that case the problem may be the USB cable, USB port, or a hardware issue.

P275 FM Analyzer / Unable to install on Win 11

I need to install the FM 275 onto Win 11 Home laptop, but am unable to get a com port to show up.

I have installed the usb drivers from https://ftdichip.com/drivers/vcp-drivers/ but I do not get a com port shown.

Any assistance would be great.

This is not standard behavior, but if you email me, we can work it out. I've reset your account to allow further key generation.

I'm aware it's been a long time coming ;D
We've had a lot of requests and a lot of small bugs to fix. It's basically done now. I expect to release at least a beta version in the next few days.

Gradually, everything will be unified to line breaks immediately after the last character of the text. In the UECP implementation this will happen in following Magic RDS 4 version.

Hi Jan, on the topic of 0x0D, will/can a switch be added between adding the CR character as the first one or last one for all connection modes (uecp, etc.) in the 2A group? Something like this  :)

Registration is not tied to an IP address, but to the specific computer hardware and specific Windows installation. If these elements change, for example due to a system reinstallation, you can simply generate a new license key under your existing user ID. If these elements are changing on each start-up, for example due to virtualization, then unfortunately the Magic RDS 4 cannot be used on such a configuration. You would recognize this in advance by the fact that Magic RDS 4 shows you a different installation ID every time you start the system.
However, we have never encountered this problem before. Try to set up a stable environment for the program from the perspective of the above. If you have no other option, we can use simple diagnostics to determine where the problem is. It probably won't be appropriate to use a preview version of Windows.
