KeySpan High Speed USB Serial Adapter

I have an older 9 pin serial port Davis Vantage Pro® weather station and needed a way to hook this thing up to my USB port in the much newer Macbook Pro® (I'm all about the Pro, people.) Anyway, the device came in the mail, I installed the drivers via the included disk, and VOILA! We're in business. Sort of depressing, though, because now I can see how much rain we're getting here in Western Oregon. Bitter/Sweet, to be sure. But the KeySpan will "hook you up" (literally) to any older device. Such as older Garmin® GPS products.

I got the Keyspan USB Serial adapter to connect my old serial  PalmOne m100 Handheld  to a new  Apple iMac G5 Desktop with 17" M9843LL/A (1.8 GHz PowerPC G5, 512 MB RAM, 160 GB Hard Drive, DVD/CD-RW Drive) . The device is straightforward, connects to everything easily, and works well. The software for OS X works well also -- zero problems -- although when you begin to install it, you are warned that the software will alter your Kernal and it may damage your operating system. You are then admonished to, "Use caution". That's it. No other instructions to help you "use caution".Disconcerting at best, though I must admit that, once I bit the bullet, held my breath, and hit the "install" button, this device and its software have worked flawlessly. Very fast transfer rate too. I would give it five stars based on its performance, but I'm giving it 4 stars instead as payback for scaring me to death with the install "directions".

I needed this for a contract job to connect a Cisco Console Cable to my laptop. It worked for the job I was in. The self install was fine. No issues.

It did not work to link my JPI engine monitor to my laptop. Sent it back and got the JPI version.

Worked to program EF Johnson 5330 and 5100 radios. Connected to radios with no issues. Other USB to Serial adapters would not connect to radios.

Product advertises that it will work with WAYCOM tablet but it does not. Contacted tech support and I recived no help. Don't know how well it works with other products, but does not work as advertised with WAYCOM

I can now get my card reader to work!

Arrived quickly. Item works great. Thanks
