Author Topic: What USB-To-RS-232 Adapter Will Work With Windows 8.1, 64-bit?  (Read 6705 times)

Virtually all the USB-to-RS-232 (9-pin) adapters for sale on eBay have a disclaimer, which states that they will not work with Windows 7 and 8 64-bit systems, even with the software drivers supplied. Does anyone know of a USB-to-RS-232 adapter that will work on a system running Windows 8.1, 64-bit?

I'm running a program called CWCOM, which allows users to send and receive Morse code over the Internet. The only option provided by CWCOM for connecting a telegraph key is via RS-232, which of course this modern laptop does not have. So, I'm trying to create one via a USB-RS-232 adapter.

Thanks

Don't look on eBay. Go to Egghead or any of the computer suppliers. Egghead has several of them that work on 64 bit machines.

FTDI makes converters certified for Windows 8.

I have purchased 3 different ones off of Ebay, and while I didn't pay any attention to any disclaimers, all three work with Win 7 64 bit here.

I just bought this one last week:
http://www.nordfield.com/usb-to-serial-adapter
It was plug and play with my Windows 8.1 HP Laptop.  Didn't have to use the supplied CD that contained the drivers.
I use it with my Garmin GPS unit...LL

Thanks, Lauri. The mention of support for Windows 8, 64-bit, in the datasheet gives me confidence.

The hardware is the same, it's the driver that is different for different operating systems. Some of the companies have a web site where you can download different driver versions. If your mfg has Windows 8 drivers available, the adapter you have will likely work.

More than the driver, the chip itself. If the chips a Chineese bootleg (lprolific), the newer drivers in windows will autodetect its a boot and disable it. The work around is roll back to the old driver but thats a real pita, sometime windows will update the driver and "poof" your back at square 1.

Just be carefull about the cheapo USB to serials.  The best is always to use a true com port on the motherboard or in a PCI slot if you have a tower with avaiable slots.  I've solved a whole lot of issues that way for the HRD users.

My 2 cents  Roll Eyes

I didn't mean to imply that any chip set will work with any driver. Only that many of the chipset mfgs have a variety of drivers available that work with their chip set and a variety of operating systems.

That Nordfield product, is an OFF the SHELF FTDI-mfg priduct.
http://www.ftdichip.com/Products/Cables/USBRS232.htm

SHOP AROUND for best pricing on FTDI USB-RS232 cables.
My Parallax FTDI USB-RS232 cable was $17, off the shelf at Fry's.

I have used FTDI for USB conversion (UART, RS-232), for over 10 years.
WHY, due to their focus on software drivers for multiple operating systems.
The hardware part is easy, the software portion was Chinese blind spot.
==
For the Prolific (Taiwan, and Chinese counterfeits) lovers from <$10 bargain bins,
Prolific is discontinuing older PL-2303HXA and PL-2303X chipsets --
since they are not writing Win8, OSX, Android, or iOS drivers for them.

Plugable PL2303-DB9 serial adapter
Purchase from Amazon
Prolific PL-2303HX Rev D Chipset
PL-2303 family chipset for widest possible compatibility. Drivers available for Windows 98/ME/2000/XP, and Microsoft signed drivers for 32/64-bit Vista, Windows 7 and Win 8; Mac OS X 10.9-6 including Snow Leopard 10.6.x, Lion 10.7, Mountain Lion 10.8, and newly released OS X 10.9 Mavericks.
Have one currently, and it works just great for serial connections into my TS-2000 and TS-590S. Second one on order along with additional 6' DB9 F/F Straight thru cable that will arrive tomorrow.
Set up easy, just connect to rig/device and plug into USB port on PC. Windows will install the current Prolific driver automatically.
My PC is a Dell 15R Touch Laptop w/Win 8.1 and this adapter may cost a little more, but the Chinese stuff sucks...................

Hello.

I have several USB 1.1 serial cables I bought at discount years ago, GE brand.
With Window 7, 64 bit, they work perfect.
Serial is so slow that being the slow USB is not a problem.
I also have used universal docking stations, same thing, no problems.

Hi,
     Make sure you get a cable with the FTDI chip set, not some clone or counterfit chip.    You may pay $20 for the cable instead of $10 for a cable with a knockoff or Prolific chip set.  However, you will save hours and hours of time.  Windows 7, 8, and 8.1 (including 32 and 64 bit) should recognize the FTDI chip set automatically.   Not so with the clones.  Any cable that requires you to download the drivers is usually bad news.    Look at a site like Amazon or New Egg and read the reviews for the cable. 

    Repeat after me.   Authentic FTDI chip set!  Good luck.
