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.

I’ve used this product for years, it’s been great until now. I’ve called support and they do not have an eta if at all to continue support for OS X.

This product is used with a TriCaster 8000 for control of a Sony PTZ camera.

I purchased this as an adapter for my datalogger as per that manufacturer’s suggestion. Unfortunately, the only thing this adapter was good for was frustration and wasted time. Following all the directions for installation and trying five different computers was no help. Neither was my phone call to the manufacturer as after troubleshooting by phone I was told that it ‘could just be an individual malfunction.’ With five different computers? I finally found a dusty old computer from my grad school days that had a port allowing me to connect directly to my datalogger without the Keyspan. So, the bottom line is that a dinosaur of a laptop was more useful than this adapter.

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…

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

I needed a serial port on a new Windows 7 (64bit) machine. This usb serial adapter did the job with no problems. It installed as COM3 but I needed either COM1 or COM2 due to application limitations. The instructions showed how to resolve this and make the configuration change and all worked fine.

Tried many of these in the past with varying degrees of success. This one is the best! It does require a driver and software (included) but it is easy to setup and stays setup even after reboots and different USB locations.

Works great. The only thing I have problems with is with the rounded end of the actual case doesn’t allow it to make good contact and kept vibrating out. I took a file and filed the end of the plastic case flat and have not had a problem since then.

I bought this adapter to use a serial port on my laptop, for use with my weather station with my laptop. It functioned perfectly and allowed me to provide weather information. If your computer has a USB port but lacks an RS232 port then this is for you!

My line of work involves a lot of communication to a wide variety of panels and controllers through RS-232. I have had issues with devices in the past and my USA-HS19 has been amazing compared to the other devices I have tried. There are others with the cable containing the communication chip, they are everywhere, but this one is the real deal. I have yet to meet a panel/controller this guy won’t talk to. Highly recommended by myself and most manufacturers, try it, you won’t be disappointed. Worked with XP through W7 64 bit. Thanks for a great product!

The driver which I tried to updat from your site will not download properly on my laptop. It downloads however it does not load when i open the application. I selected the Windows 7 Beta driver for my USA-19HS interface unit. My laptop does not recognize the unit when i plug it in. The power on indicator lamp (LED) does not come on.

I’ve used this on several installations and at home. Works Great!!

I have an old Bonding Resistance tester that blows out modern serial ports. I think it must use the old 25V RS-232 signal levels. I got a whole box of random serial adaptors hoping at least one would work with the instrument. After blowing out 8 of them, the USA-19HS worked. Hopefully they keep making these. Some of my customers have legacy equipment that they need to keep going.

I purchased this to get my OLD Wacom 12×12 working with my mac, no go. Oh well. However it did solve a problem with an old Calcomp plotter we have. Works on modems too !

I have used many USB-serial adapters over the years, and this Keyspan product is by far the best. It is the most reliable adapter I have used. I also like the software that comes with it, which allows you to actually see the data that is being transferred through the serial port.
