Keyspan High Speed USB Serial Adapter (USA-19HS)

Bought this to work with Allen Bradley PLC's and it worked great. AB can be some of the most difficult to communicate with but the adapter worked flawlessly.

Did not come with a Windows 7 driver although there is one available for dl. Had to install/uninstall a few times but now it works well.

This product does exactly what it is supposed to do: converts your USB port to serial port. Hassle free, easy setup and use. I use it to connect to console port of Cisco routers using my laptop. Reliable, solid piece that works when you need it.

I did not even have to install a driver, since Windows 7 already has the driver as part of the operating system. Works really well without any problems.

I use this product to extend my usb range to the server room in order to transmit key card information. I like that the product is strong, easy set-up and does the job trouble free.

I'm using it on a 7 year old Mac PowerBook G4 computer to communicate with a vintage Tandy CoCo3 computer. Zero configuration on my part. Worked on first attempt and ever since!

Pros: Works great for a variety of applications. The driver support is one of the best for this type of the device.Cons: Cost.Works great for a variety of applications. The driver support is one of the best for this type of the device. Cost.

I needed a serial port to hook up my computer to my computerized telescope. This worked right out of the box on my Windows 7 32-bit PC...no drivers from the CD required. I ve read online that this is one of the most reliable one of these out. Costs a bit more, but in my opinion well worth it.

I was looking for USB to serial adapter which will work under the Windows 7 and this adapter does exactly that. Even better - Windows 7 already has built-in driver for this adapter!

I bought this in the hopes of being able to use an older (large and once expensive) Wacom Intuos GD graphics tablet on a newish Mac Pro running OS-X (10.5.8). Initially, the combination did not work but then I found a freeware program called Tablet Magic that got the devices talking to each other. (I have no connection with that software maker but was pleased to find it). Some of the pen responses can be a little twitchier than I'm used to (with my USB tablets) but otherwise this adapter (and that software) has made it possible for me to use an old serial connection Wacom GD tablet on a current Mac. So, the product seems to work as described for this use. That's impressive when one considers that Wacom says this should not be possible (with usable results).

So far the best of any USB-Serial adapter we've used. Fewest issues and conflicts. Not cheapest but worth the extra $ to be able to eliminate it as a problem source. We use them in marine navigation electronics integration.

It's good. It was little hard to install it on my Windows 7 OS. If you are not tech savvy, I wouldn't recommend it to you.

Pros: Easy to install, with drivers supplied. Seems to work OK most of the time.Cons: Occasional BSOD's with "IRQL_NOT_LESS_OR_EQUAL (a)" message, about once a month or so. Debug information points to keyspan usa 19hs.Easy to install, with drivers supplied. Seems to work OK most of the time. Occasional BSOD's with "IRQL_NOT_LESS_OR_EQUAL (a)" message, about once a month or so. Debug information points to keyspan usa 19hs. Get an FTDI USB - Serial adapter instead; they work perfectly.

The only USB converter that I found that works with Windows 7 64 bit. Just plugged it in, windows went out and found the driver (did NOT have to use the CD that came with) and it works it works, it works!!

My new PC doesn't have a serial port, so I googled USB/Serial Port and the Keyspan looked like the one that would do the job at a fairly reasonable price.

Pros: High quality piece of equiptment. Does exactly what it says.Cons: I needed it to connect a serial Intuos1 to a Win7 machine. Even thought I read multiple people saying this was the only adapter that would do it, I was not able to to even after trying all options and combinations of drivers. No fault of the equiptment, it's a limitation in Wacom's drivers apparently, the adapter DOES see the tablet in Win7.High quality piece of equiptment. Does exactly what it says.

Works wonderful and just the way I was hoping it would work. Easy to install and use!

Pros: supposed to offer best compatibility??? 3 days ago, before purchase, I called in to keyspan to check compatibility. Tech offered that they were waiting for Certification of their Win7 driver and might come out end of month. Also said the device uses a TI chipset (I wanted to make sure it was not prolific).Cons: Will not work with Quick Basic V4.0 compiler. Same program works with a Cables-to-go prolific adapter (with XP driver as win7 driver has bug). On Keyspan, the blinking light will not go solid when opening the com port in Quick Basic. (Will open with FreeBasic, but no good for my app.) Called Keyspan and got no help. I was told if the adapter works with something else, then, it just is not compatible with QuickBasic. Even running the "immediate" mode of QuickBasic, opening com2 does nothing. That's it. I will send in an email to see if I can get help.supposed to offer best compatibility??? 3 days ago, before purchase, I called in to keyspan to check compatibility.

Used to interface a serial port multiplexer w/ a new USB only computer. It was plug and play after adjusting baud rate.

Excellent product for what I use it for. Much better then others I have tried and have not been able to provide the speed required.

Required CD to install drivers; has worked perfectly ever since.

Pros: Excellent product, works flawlessly with XP, Vista (32/64) and windows 2003. The supplied drivers allow a great deal of flexibility with port configurations.Cons: None.Excellent product, works flawlessly with XP, Vista (32/64) and windows 2003.

I use serial communication to control equipments. Have problems with 4 other brand usb-serial adapters until I got this one.

Pros: Works great with OSX, Solaris and Linux. I own a few of these, and they have come in quite handy for getting serial console on Sun servers, switches, routers and so on.If you use something other than windows, this is the usb-serial adapter you need.Cons: Requires Driver to be loaded first.Works great with OSX, Solaris and Linux.

Requires Driver to be loaded first. Wish it came with a longer USB cable, but at least it's detachable and you can use a standard USB cable to replace it.Wished it was a bit cheaper, but then this adapter just works, never had a problem with any of the ones that I own--unlike some of the cheaper knock offs.

Got this device, loaded the software (CD included) on my Vista 64 bit machine, plugged the unit in, and it worked great with my Garmin GPS 12. No muss, no fuss, no drama. No searching around for 64 bit drivers. The only thing is to pull up the quot;Keyspan Serial Assistant quot; software and note which COM port it has assigned itself to (in my case, COM6). If you have a Vista 64 bit machine, you can try other brands and models, poke around the web for official manufacturer drivers, beta drivers, or third party drivers. Or you can use this and just get to work

Pros: Works as expected. Works great with the mac for which I needed this for.Cons: Should have gotten one soonerWorks as expected. Works great with the mac for which I needed this for. Should have gotten one sooner

This USB serial adapter worked with all of my applications whereas the Belkin adapter did not.

I recently bought this USB adapter to connect to my G5 Mac server's serial port with my other Mac. It just worked like charm out of the box.

Actually seems to fully comply with RS232 standards, and so works with any remote RS232 equipment. Has associated test and setup options for getting USB behavior for…

I bought this to connect my MacBook to a Parallax BOE board. Within 15 minutes I was programming the Basic Stamp module on the BOE.

Works as advertised. Works with both Windows and Mac. Works in VMWare too! Perfect!

Pros: something that is well put together and whql certified drivers.Cons: could use a slim down versionsomething that is well put together and whql certified drivers. could use a slim down version if you want something that is sure to work 100% of the time then this is the one. It is not a cheap adpater, but it includes a CD with the driver on it, which is WHQL certified. this is a must for any network engineer who types show ip int brief on a daily basis.

No problem with this device, the software is well designed. You can view the status and change port number to match your applications.

Pros: Easy to use and small enough that it is easily portable. So far has been really reliable.
It has worked with a variety of equipment that I have used it on.Cons: None so far

I installed it on a 64-bit Windows Vista environment without any problems. It works as described.

Works with Mac OS X with Intel processor. I use it to connect my GPS.

Pros: Quality and compact design with a status light during data operations. Excellent user documentation as well as extensive testing, monitoring and "debugging" capabilities.Cons: Have not encountered any negatives for this product. It performs as advertised.

I have used the adapter with nothing but great results. It has worked seamless no matter what security system i seem to be working with. Thank you Keyspan for your excellent sales ann service with my product and I wish you all the best.

Bought this to connect my eTrex Legend to my iMac - worked perfectly with minimal fuss, unlike other USB-serial adapters I tried. The price is a bit higher than those other adapters, but worth it due the the minimal headaches. It just works.

Great product and support. Easy to load software and interface to PC.

Pros: I have had many of these. Works right out of the box with windows XP & Vista.Cons: Plastic overhangs rs232, makes it hard to plug directly into a plugI have had many of these. Works right out of the box with windows XP & Vista. Plastic overhangs rs232, makes it hard to plug directly into a plug how about a software null modem setting?

Received product, plugged it in and it worked fine. Couldn't ask for more!

This USB to RS-232 adaptor worked perfectly. It solves the problem of how to get a good old-fashioned serial port when today s PCs only come with USB ports. The software was easy to install and use. Changing the COM port number is a breeze.

Pros: I'm sure this product may be fast but you are trying to use a device that requires serial i doubt you need to worry about that.Cons: Not fully plug and play. If you are running windows you actually have to go to Keyspan's webpage, download and install the software. only after this is it truely plug and play. If you are running Linux you need to be sure to have selected support for this before compiling your kernel. This product is way to expensive to go through all this hassle.I'm sure this product may be fast but you are trying to use a device that requires serial i doubt you need to worry about that.

Not as nice packaging as some of these cheaper units (all in one). Had issues with 2 units based on prolific chipsets. Both had issues. This unit as well as a socket IO PCMCIA card version worked flawless. If you need reliable RS232 signals, this beats the other ones.

Pros: It got my 12-year-old Wacom ArtZ graphics tablet working on XP. The adapter replaces a PCI serial card, to free the slot for a sound card in a slot-challenged MB.Cons: More expensive than the Prolific-based serial adapters.It got my 12-year-old Wacom ArtZ graphics tablet working on XP.

I've tried the cheaper adapters but they won't work with my Wacom serial tablet.

Pros: Turns a USB port into a 9-pin high-speed serial port, no muss, no fuss. Drivers work fine, and Keyspan updates the drivers fairly quickly as OS updates cause problems, even when they discontinue a particular model and replace it with another - the old model still gets driver updates.Cons: Wish it was cheaper, but I'm willing to pay extra for stability & reliabilityTurns a USB port into a 9-pin high-speed serial port, no muss, no fuss. Drivers work fine, and Keyspan updates the drivers fairly quickly as OS updates cause problems, even when they discontinue a particular model and replace it with another - the old model still gets driver updates. Wish it was cheaper, but I'm willing to pay extra for stability & reliability I had used one of these Keyspan adapters with an older Mac for over 5 years now, any time I had a problem I checked the Keyspan site and they had an updated driver available that quieted my piehole.

Pros: It works solidly when others don't. USB A to B connection a minor plus.Cons: I haven't broken it yet, but it's just a matter of time. The case is 2 shells held together by integral finger clips. These generally break easy. I suppose for some, the ability to take it apart easily could be a plus, but is outweighed vastly by the danger of breakage. This can be overcome by taping or gluing it, but shouldn't be needed on at 3x the cost of competing units.It works solidly when others don't. USB A to B connection a minor plus.

This can be overcome by taping or gluing it, but shouldn't be needed on at 3x the cost of competing units. I didn't list cost as a con because the magic of this thing is in the driver. A great many times this kind of device is needed, it's used by a software app that may not have passed the highest commercial test rigor. Also, directly accessing hardware, which windows only 'tolerates', has the makings of crash written all over it. The standard Prolific driver that comes with most of these adaptors crashes apps and bluescreens occasionally. This one does not, at least for our uses. Thirty bucks is nothing compared to the business cost of even rare crashes, so stability gives it 5 eggs - 1 for a flimsy case.

Worked fine. Then I upgraded the laptop. No serial ports. Bought the Keyspan High-Speed USB/Serial Adapter, USA-19HS. Worked perfectly Back in business.

Pros: Works fine with Garmin eTrex GPS. No problem recognizing my GPS in MapSource. I know that some other devices like this don't work with this particular GPS.Cons: Price.Works fine with Garmin eTrex GPS. No problem recognizing my GPS in MapSource.

Pros: I use this on an AOpen MP965-D with Vista Ultimate with SP1 OS. The Keyspan device installed without problems. The serial port shows up as COM3. The com port may be reassigned. The MP965-D has no serial ports however I've left it as COM3, personal choice.It works. Period.

Pros: Allows you to add a serial port to your laptop.Cons: I had a pretty challenging time getting this to work with my Mac, through Parallels. Would work sometimes, not other times.

Not worth the trouble for my purposes, but it's nice to have just in case.

This is the only usb to serial convertor that I have found to do true two way communication. It works great. I have to use it with older programs that require modems and as we all know getting a computer with a db-9 is about inpossible.

I have a special application that requires 115,200baud with handshack. I could not get this product to work for this aplication even though I know the chip inside is capable of working for this application.

As another review I spotted also noted, the Keyspan accompanying software has a nifty port mapping indicator which shows what you have currently or, better yet

The device seems a little bigger than the photos show, but installation is simple. After installing the driver, the configuration applet made the set up of the virtual COM port quick and easy. The tool tips in the applet give helpful explanations and suggestions for all the various settings, but the tool tips must be enabled first on the Help tab. Once the serial adapter was configured, I plugged it into a Keyspan US-4A USB server that I already had and now the serial console port on my modem is connected through my LAN. The two devices, the serial adapter and USB server, work together flawlessly and provide transparent access to the modem s serial port. I m so impressed with the USA-19HS that I just bought another one.

Pros: Looks like a good product, but DOA.Cons: Device DOA. Device manager shows "TUSB 3410 Boot Device", which according to Keyspan's FAQ and "it indicates that you have a defective Keyspan USB Serial Assistant.
