Top Customer Reviews
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. The Keyspan is inexpensive and has proven to be 100% compatible with everything I've needed to connect to via a serial cable.
I've used it with laptops and desktops running Windows 98SE, Windows XP and Windows 7. I've used it on SLC 5/xx series processors, ControlLogix 5000 processors, Siemens/TI 505 series processors, Keyence laser measurement equipment, modems, serial printers, barcode scanners, Reliance and Rockwell/Allen-Bradley drives, and just about everything else. Never a problem. It works with straight serial cables, null modem cables, and every type of serial adapter I've thrown at it. The Keyspan USA-19HS is the cheapest piece of control system communication hardware that I own, and it's probably the most-used. It has never let me down.
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.
UPDATE 4/5/12: it appears that Tripp-Lite has made a few changes since they took over the Keyspan line. Among the changes was a decision to use a cheaper USB socket. From the outside, it looks almost the same.Read more ›
After executing "mknod /dev/ttyUSB0 c 188 0", I am happily communicating with Palms and GPSs using the new /dev/ttyUSB0 device.
The device works fine, but heaven forbid you actually need to get it replaced. At this point, I have neither my dead device nor a refund -- I mailed it in, and it's gone in a black hole.
