Gearmo USB to RS-232 Serial Adapter w/LED Indicators, FTDI Chipset, Cross-Platform Compatible, 36in Cable

I needed an RS232 port for work that I do. I wanted it for an old laptop I had. As soon as I got my software, (a C++ compiler) set up for this new port it worked instantly and I was away and programming. That is the kind of product I want. No fooling around with special setting or anything, it just works. 5 stars and worth every one.

I needed these to connect to my Rigblaster M8 Digital Interface and my Yaesu FT-1000MP Mark V HF Amateur (Ham) Radio Transceiver to use for doing digital modes such as PSK31, MFSK16, Feld-Hell also known as Hellschreiber, and other numerous digital modes. I used the Prolific cables and drivers with Windows XP and Vista with no problems, but they would not work with Windows 7 Home Premium (64 bit). My PC would either freeze up after a few seconds when running MixW or Ham Radio Deluxe or Digital Master 780 which is built into Ham Radio Deluxe and sometimes would give me the blue screen of death crashing the PC. As soon as I plugged these in (I had to buy 2, one for the Rigblaster's CAT port and one for the Yaesu HF radio's CAT port) Windows 7(64 bit) automatically found and installed the FTDI drivers without having to use the driver disk included with the cable and all is working great now! I'm very happy with them and am back on all the digital modes. About the only thing I didn't like about them is the cable could stand to be about 1 foot longer. I use them on a Dell 17R (N7010) laptop and can sit it pretty close to the radio, but if I were using them on a desktop PC I don't think they would have reached without a little bit longer cable than the one provided here unless I had the CPU sitting on the same table as the radio. They would probably not be long enough if you have to sit your computer in the floor beneath the table the radio sits on. Amazon has longer ones available although they also cost more. I also had to purchase a DB9 female to DB9 female adaptor to adapt the one on the HDMI cable to work on the Yaesu FT-1000MP Mark V radio due to Yaesu being the odd man out and them installing a "male" CAT port on their radio although every other amateur radio manufacturer has a female CAT port on their radios. I had to also purchase a DB9 female to DB25 male adapter to use on the old West Mountain Radio Rigblaster M8. The newer digital interfaces currently available have USB ports installed and USB ports on most newer model HF radios as well. Also, you can now buy interfaces that have their own built-in soundcards which reduces the need for audio cables to run between PC and interface altogether.

I've purchased a number of these and they work great, at 250Kbps and under.The current advertising states that it uses a ZT232E transceiver that is good up to 920Kbps (at least, that's what I assume "Ultra Fast 920K ZyWyn ZT232E" to mean). In reality, the unit I received has a ZT213LEEA, which is only rated to 250Kbps. Side note, the ZT232E is also only rated to 250K, the ZT232F is rated up to 1Mbps. Other than that, the units work great.

Those of us who do embedded development are probably all familiar with the FTDI chips. They are supported on Mac, Linux, and even Windows. When I needed to order a USB/RS-232 cable it dawned on me to look for one which used the FTDI chip family, since I would already have the drivers in place on all of my machines. A quick search here on Amazon for "FTDI" led me to this product. I have only just received it, but since no one has previously reviewed it, I thought I would go ahead and share my first impressions.As I hoped, it was compatible with the FTDI drivers I already had installed, so no additional drivers were needed. It is a good thing that they weren't because the drivers which shipped with it were on one of those annoying (and in my machine unusable) mini-cds, a fact which caused them to get four stars instead of five.Overall, the unit is nicely constructed. It has an LED activity indicator, which is a very nice touch. The electronics are housed in the translucent blue shell for the DB-9, and it is ever so slightly on the bulky side. This shouldn't be a problem normally, but if you had a tight squeeze on your serial connection, it could be an issue.I'm very happy with my purchase, and plan to order a couple more to have on hand. If you need drivers and can't use the mini-cd, they are readily available at the FTDI web site - Mac, Linux, or Windows.If you need a usb/serial cable, especially for Mac or Linux, I believe this one would be a good choice.

Have multiple PL2303 Prolific based adapters which no longer work with Windows 10. This adapter, with the supplied driver, works perfectly! The blinking tx and rx lights are fun as well! Some of the reviews have discounted the drivers supplied (on tiny DVD), but I found them useful. Great product for those of us will legacy software that still wants RS232!

Purchased to replace my older PL2303 Prolific based adapter. The old adapter still works great and has been passed on to a coworker, but it's difficult to get a real Prolific these days with all the cheap knockoffs that won't function. Choosing to avoid that whole headache, I went with this FTDI based adapter. As others have said, ignore the cd that comes with it and download the FTDI drivers instead. I've had no issues with the drivers or the hardware at this point.

This works beautifully in Windows 10 if you ignore the funny little CD rom that comes with it. Even if you can read it (you probably need to use a laptop machine to be able to) it shows about 10 or so manuals, none of which match the model number at hand. On a guess I simply inserted the USB connector, and Windows installed the driver for me. Very simple, but a little scary since for some devices it is critical to install drivers prior to insertion.

the product work great, but always have high shipping cost and import duty to payif it was not the only one dealer recommendation certainly go with another one cheaper

good product, good seller
