20 Most Recent Belkin USB/Serial Portable Adapter (F5U409-CU) Serial Adapter Questions & Answers

The F5U409 will not work with 64-bit editions of Windows Vista or Windows 7. Most Windows 7 installs are 64 bit.

Hello,

What version of windows are you running on the machine it doesn't work on? This adapter does not work with windows vista 64bit or windows 7 64bit. It only works with 32 bit operating systems such as windows 98, xp vista 32 or windows 7 32. If you need one that works with 64bit you can buy the Belkin F5U257.

If you have a 32bit OS try uninstalling the software and reinstall with updated drivers from here:
http://en-us-support.belkin.com/app/answers/detail/a_id/308/~/f5u109%2Ff5u409-usb-pda-adapter---drivers

Now plug the device in and try to communicate again with your serial device. Most devices only recognize com1 or 2 so make sure the usb device is set to emulate either of those ports.

I had the same issue myself. I purchased this device (that has Windows 7 drivers) - http://www.amazon.com/Keyspan-USA-19HS-Hi-Speed-supports-Sequence/dp/B0000VYJRY

call belkin and see if they have drive for this device.

Download the appropriate Windows 7 driver from here:

Use the 64 bit one if you have a 64 bit OS, and a 32 bit one if you use a 32-bit OS.

Or you can download both, start with the 64 bit one. If it is not compatible, the installer will complain and abort.

in the device manager click on (ports lpt com) double click on belkin usb adapter the properties will open then click advanced ant set the com port. you will find the driver here https://www2.belkin.com/support/product/?lid=en&pid=F5U109&scid=1

try this http://www.belkin.com/support/articl...id=5368&scid=1

first of all you be sure that you do not have Vista on 64 ..cause this device is not compatible with Vista or windows 7 on 64..
If your vista is on 32 ..and the driver for both the adapter and the pda are installed than and only than will the computer communicate with the pda..
So be sure that you use the disk that came with the pda. and install the driver ..and be sure that the operating system that you have in use is not on 64 ..bit ...

hello, No this model is not compatible with Vista 64 bit. its compatible with only 32 bit Vista.
However there is a similar model which is compatible with 64 bit Vista and the model number is F5U257 (USB-to-serial).

link from Belkin confirming F5U409 not compatible with 64 bit.

According to a tech support person at Belkin, this device is compatible with OS8x and OS9x, so it is not going to work with OS10 unless new drivers are released.

The drivers available so far are listed here:

You need to isolate the problem. You may need to connect the USB-Serial adapter into different USB port of your computer or you may want to try connecting it into different computer. If you get the same problem after using different computer, you may need a driver for it. Or it could be defective.

Have a great day!

make sure that both the cable and the software that you are using are set to same Com ports.

Ex. the cable set to Com4, the software must be set to Com 4

To change the Com ports of the cable you just got to Device Manager under System Properties then on the properties of the serial cable there is an option to change the Com port settings.

To change the Com port setting of the software just simply go to its settings or preferences.

You can download the drivers for your device on the link below:
