Rated 5 out of 5 by from Horrible support. Does NOT maintain its drivers. Company REFUSES to acknowledge that their driver signature is no longer VALID and does not work with Core Isolation turned on. Company bought 8 of these and they are worthless. Find a company that actually supports their product and doesn't continue to use a driver from 12 years ago ( Current driver for Win 10 says May 22, but is from 2010.

Rated 5 out of 5 by from Need OS X Lion support This is a great product but we really need that new driver for support under OS X Lion. I have a number of people who are holding off on purchasing the 19HS until then. The device is very reliable and performs well. Nice multi-platform support overall.

Rated 5 out of 5 by from AV Industry must have A lot of legacy and even current AV equipment still uses serial cable communication. I have a MacBook Pro running Yosemite, with Windows 8.1 running in Parallels. MOST of the AV configuration software is Windows only. This device allows my Virtual Windows PC to talk to an external serial device with this adaptor as if it were all native on it's own machine. Fantastic!

Rated 5 out of 5 by from Communicates Successfully Every Time I have hundreds of clients who have equipment with which I occasionally I have to communicate. I use an Apple laptop with the latest OS. Because the client's devices use only PC Windows, I use Parallels to convert to the Windows platform. Then I use the Keyspan serial adapter and a special modem to get the signal onto the phone lines. The Keyspan works every time.

Rated 5 out of 5 by from Rock solid compatablity. I use the 19HS and the 49WG (4 port) with my ham radio gear. I have never had any type of issue where the software did not recognize the adapter as a native serial port. I went through about a half dozen other brands giving me some sort of problem before I found this adapter. The software is also in a class of it's own. I will not buy nor recommend anything else.

Quit working for some reason. I have tried everything I know to make the signal active between the device and the Lenz DCC control system. The computer sees the hardware, the drivers show in Terminal and go away and return when plugging and unplugging the Tripp Lite device. The Tripp Lit worked on this computer for several months and the computer upgraded to Catalina OS 10.15.7 then nothing works any more. if you have any answers I am open to try them.

Rated 5 out of 5 by from null The plug and play driver for this causes BSOD's on just about every computer i tried to use it with. Not sure if TrippLite ever got around to releasing a functional driver for this, but this is not ideal for recovery/service hardware if you have to chase down a driver.

Rated 5 out of 5 by from null If you configure network gear and you are using a somewhat slimmed-down laptop/ultrabook, then you absolutely need one of these. If you have a USB port, you can plug this in and use something like Putty or TeraTerm to connect to your network devices for serial configuration. An absolute must-have for any network admin worth his salt.

Rated 5 out of 5 by from One of the most reliable USB to Serial adapters we've seen... I buy these for our techs 5-10 at a time. We've tried a few other USB to Serial adapters, all of which we had issues with. Not the smallest, but these have been rock solid, work every time. The software makes it easy for the user to see what Com port the device is using. The connector is a USB A connector held in by friction, and won't take too much cable weight, but if not put under strain stays in fine - if you swing it around a server room a lot you could add heat shrink, cable ties, or a rubber band to make sure it stays in tight. We've had fewer issues supporting our techs with these than any other adapter. We have over 100 mobile techs around the country and world using them to program routers, or load firmware in various types of devices...

Rated 5 out of 5 by from Reliable and consistant Service This serial to USB adapter cable was bought as an interface between my laptop and controller on my model train layout. It was a model recommended by the manufacturer for this use. It works flawlessly and consistently. It is a little more costly comparing it some other manufacturer's models but in my opinion was worth the extra cost.

Rated 5 out of 5 by from I like that it just works with little effort. most pc's and laptops no longer have serial adapters but many pieces of equipment still need a serial connection to configure them. the Keyspan USB Serial Adapter is just what I need to get this done.

Rated 5 out of 5 by from This USB to DB9 Adapter Works Great w/ Fire Panels If you are working with a Gamewell-FCI panel, I recommend purchasing this product as it works great when downloading your HyperTerminal reports and/or downloading programs to the panel. This is also recommended by Gamewell-FCI tech support and I can see why.

Rated 5 out of 5 by from works on Mac OS-X 10.6, XP etc. On my MacBookPro with VMware Fusion, the device is working on both OS-X (native) and XP (VMware). On the Mac, you have to figure out with the serial assistant how to name the port. Next I worked smooth with SecureCRT. Then I upgraded to OS-X 10.7, waiting for the driver now...

Rated 5 out of 5 by from Best USB / Serial Adapter Out There Contrary to other posted comments, this device does work with El Capitan. I have two that are on two different computers (an iMac and a MacBook Pro) that receive daily use. About to purchase a third for a relative to use on a Mac Mini. I've deployed these on several Windows systems too. Absolutely 100% reliable and works without a hitch on both Mac OS X and Windows.

Rated 5 out of 5 by from The most reliable adaptor for PLC's, Automation and Drives As an automation company specialising in upgrading obsolete PLC's from Toshiba, Siemens, Rockwell and Drives from Parker, Siemens and other ancient kit this is the only adaptor that has been proven to work across so many hardware platforms. We use these to connect via VM's, directly from the OS and they've never let us down. We've tried other units from maufacturers like St@rt3ch to name just one and they either don't communicate correctly or fail prematurely in a harsh industrial environment.

Rated 5 out of 5 by from Product worked well on my Mac and now it doesn't I use this product to connect to a broadcast device and transfer small amounts of data. It used to work fine until I upgraded to MacOS Sequoia. It's very very slow now and when I contacted support I never heard back. I wish support for this product was better since even to install the drivers you have to do a workaround that's not documented on this website. I hope they fix the bug soon though or at least contact me back.
