PRODUCT DESCRIPTION

Do you need a cost-effective and reliable solution for connecting a serial device to your USB computer? Keypsan by Tripp Lite's USA-19HS USB High-Speed Serial Adapter is the easy way to add a serial port to a computer without the hassle of installing a serial card, turning off the PC or connecting an external power adapter. The USA-19HS draws power directly from your computer through the USB connection. Simply plug it into the USB port of your computer using the included cable, install the software and you're ready to connect a serial device. An LED shows adapter status and data activity at a glance. Featuring data transfer rates up to 230 Kbps, the USA-19HS can be used with any RS-232 serial device—modems, GPS devices, cell phones, hand-held scanners, point-of-sale systems, touch screens, medical and scientific instruments and more. The USA-19HS is broadly recommended by serial device manufacturers due to its dependability and “Best in Class” compatibility.

Wide Compatibility

Tripp Lite's USA-19HS USB to Serial adapter supports Cisco break sequence, whereas many, if not all, other USB to serial adapters do not. This allows the USA-19HS to be compatible with a much wider range of serial devices than competitors' products, and is a much more trustworthy and reliable product.

Bus Powered

There's no need for an external power adapter! The USA-19HS draws power directly from your computer via the USB connection.

High-Speed Data Transfer

The USA-19HS supports data transfer rates up to 230 Kbps—twice the speed of a standard built-in serial port.

LED Indicator

A green LED shows adapter status and data activity at a glance.

5 out of 5 eggsExcellent

Pros: It just works, period.

Cons: None.

Other Thoughts: I just purchased on of these for a fellow technician. I've had mine for years and it's performed flawlessly. The USB cable did fail about a month ago but the device is just fine. Keep in mind that the cable failed after several years of use, so that's not bad at all.

5 out of 5 eggsOnly Adapter For Mac to Vinyl Plotters

Pros: If you are running a Mac, and you happen to be doing vinyl plotter work, with a plotter that isn't over $5000 and has it's own USB plotter drivers, then this adapter is for you. I've now used this exact adapter on 4 separate set-ups. From Chinese import plotters to a GraphTec. This is the only USB to Serial Adapter that will work consistently. I've tried going with the less expensive models, only to be left frustrated and still with a non-working plotter.

Cons: The price is high, especially if you just bought an import plotter, chances are that you have vinyl to cut, no extra budget or days to wait for another device before you can get started. Been there, and it sucks. So I will now never be left without one of these. Hopefully they continue to make them for years to come.

Other Thoughts: I've heard this also works with Mac to Laser Cutters as well. I haven't had the opportunity to try that, but when the time comes you can bet that me and my KeySpan USB to Serial Adapter will be right there in the trenches. Proving that Macs can be viable workplace machines that can actually output tangible and profitable objects, and not just a designer's choice.

5 out of 5 eggsThe best there is.

Pros: This is the best converter I've used or seen used. It has worked every time. The serial assistant software it comes with is very helpful when trouble shooting connection issues.(I'm not big on OEM software usually but this time it is actually good!) I have connected to most all AllenBradly equipment from PLC 5 to the most current drives, I've also used it for connecting to RFID readers, etc. I have never had any issues with the device.

Cons: None, I tried to think of some and I cant.

5 out of 5 eggsPerforms Better Than Prolific-based Adapters

Pros: Until recently, I've always used adapters with Prolific chipsets for connecting to the ECU in my race car and they have always been flaky at best. My previous adapter (one of the better Prolific-based adapters) was so bad it was actually corrupting the data going to and coming from the ECU, which presented itself as large gaps in data recorded while the car is on track. As soon as I installed the KEYSPAN adapter, all subsequent data logs were fully intact. I can finally review the data log and make sense of what's going on inside the engine again.

Cons: The adapter doesn't have thumb-screws, it only the nuts. This is only a problem if you're trying to connect to something which also only has nuts and no thumb-screws. A simple fix is to add a serial cable between the adapter and the device. But this is, of course, simply another piece of hardware that can go bad.

2 out of 5 eggsWas once the best USB serial port adapter for use with control system hardware

Pros: I've been using the Keyspan USA-19HS for years. The first one was purchased after reading recommendations from several control system experts, and I haven't been disappointed. Rockwell Automation sells their own version of a USB serial port adapter (PN 9300-USBS), but it's about $130. Don't bother.

I've used it with laptops and desktops running Windows 98 through Windows 7. I've used it on all types of equipment. Never a problem. It works with every type of serial cable adapter I've thrown at it.

Since I first started using the Keyspan adapter, I've bought over a dozen more for service techs, co-workers and even a couple of bosses. The Keyspan is extremely configurable, fast, reliable, durable and easy to use. The Keyspan adapter comes with a driver CD and a USB cable and takes just a few minutes to set up. I keep one in my laptop bag at all times.

Cons: Tripp-Lite has made a few changes since they took over the Keyspan line. They now use a cheap USB socket. From the outside, it looks almost the same. The only notable difference is a lack of molded numbers (1, 2, 3 and 4) on the end of the plastic tab in the middle of the port. Unfortunately, the cheaper USB socket doesn't retain the cable connector as well as the older ones did. The weaker spring conductors allow the cable to be pulled most of the way out of the socket very easily, resulting in a lost connection and possibly a BSOD (blue screen of death).

Whereas the old Keyspans would easily support the weight of the adapter + a 10 ft. coiled-up serial cable, the new Keyspans cannot. I tested 3 of the new Tripp-Lite adapters and all performed equally bad.

I replaced my USB port with an FCI port (PN 61729-1011BLF - about 54 cents). No more problems. The quick fix is to either glue the USB cable into the port or use tape or a heavy rubber band to retain the cable.

Other Thoughts: Don't buy this adapter if you plan to use it anywhere but on a desktop. The old versions are great for field work, but the new ones simply can't hold onto the USB cable well enough to keep a good connection. It's a real shame that Tripp-Lite would ruin the USA-19HS by skimping on parts, but that's what happened.

I've had good luck with the Digi Edgeport/1 USB-to-serial adapter. The one I have uses a high-quality USB port that grips the USB cable very well.

Manufacturer Response:

We sincerely apologize for the inconvenience and will promptly replace any units affected by the issue you describe. We recently discovered that some USB connectors supplied by a component contractor were out of tolerance. As a result, the cable did not fit into the connector as snugly as it should. As soon as we detected this issue, we immediately took corrective action, including recovering as many of the affected units as possible, changing suppliers and adding a revised testing procedure to our production process to prevent any future issues. Unfortunately, some units reached customers before we were able to retrieve them. Please contact the Chicago based Tripp Lite support team at 773.869.1234 or techsupport@tripplite.com so we may assist you. Thank you.

5 out of 5 eggs

Pros: This was the only adapter that worked well with my application which included; windows 7 64 bit, xp mode, and digigate hardware and software(gate system for storage facilities which are compatible with xp only!). In order to attach my digigate hardware, i had to bridge the port from my windows 7 into xp mode. From xp mode, i attached the usb device which worked flawlessly with both my digigate software and hardware.

Cons: Since im working with xp mode, i had to manually attach the usb on the xp mode every time xp mode is turned on or restarted. But thats rather a problem of xp mode.

Pros: Got it connected to a windows 7 machine and a 1995 brother embroidery machine. The software was a bit odd, but very configurable and ended up working out great.

Cons: high price, but worth it if you really need it

5 out of 5 eggsReliable under Mac OSX, Windows and Linux

Pros: I've carried this piece of hardware in my backpack for several years and it has never failed me or several of my coworkers. I've used it to console into Cisco, F5, Sun, HP, and IBM equipment, PDA sync, configure DSL modems w/o issue. It works under Mac OSX 10.7 (Lion). Make sure you have the 10.6 32/64 bit drivers installed.

Cons: Requires Mac and Windows drivers
