Easy conversion
Worked as claimed. Need to install the drivers that come with it, but that was easily done in Windows7.
USB to Serial Adapter Cable that works.
I installed the software on two computers, A) Windows 7 pro and B) Windows XP Pro SP3 with no problems. Adapting older hardware to newer systems can be frustrating but so far this has allowed me to use a 10 year old serial writing/drawing tablet rather then tossing it out.
Nice connector
Arrived quick. Works like it should. It comes with a 9-25 pin adaptor, too.
