 Works great!Jul 22, 2010
I purchased the Keyspan unit to interface between my laptop and Argo navis telescope guidance computer.
No problems at all....installed on an Xp OS.
Keyspan is Great ProductJul 06, 2010
I purchased a converter from usb to Serial at the lowest price point I could find and it was a waste of money. I bought the keyspan converter and it worked perfect the first time with no work on my part at all
It WorksJul 04, 2010
What more can I say. It just works as advertised. It works on a Macintosh computer running OS 10.4.6 and on the same computer running Windows XP sp3. It works even on a Windows PC as well. The only time you may run into problems will be using the adaptor and your computer with a device that has ancient hardware/software that will not work with any RS-232 to USB adaptor. In this case you will need to find an old computer with a dedicated RS-232 connector.
Keyspan USB Adapter and Windows 7Jul 02, 2010
Apparently the drivers for Windows 7 have not been written for the Keyspan USB Adapter, after searching the web and not being able to find drivers I used the ones provided on the disc from Keyspan for Windows XP instead and they seem to work fine.
I have not had any problems with the Keyspan Adapter which we use for communications to security panels and access control devices.
OS X (Snow Leopard) CompatibleJun 30, 2010
I bought this for a MacBook Pro (no serial port) so I could console into servers and network equipment. I installed the drivers, plugged everything up, and consoled successfully into a SunFire server via the LOM without issue. For the technically inclined: With the driver installed, when you attach the device you'll get a new device (/dev/tty.KeySerial1). To console into a system, simply open a terminal (Terminal.app) and issue the command:
screen /dev/tty.KeySerial1 9600
