Works 1A. tested with iMAC 10.9 and Win7Pro

iMac running Mac OS 10.9 (is improved)
After I had my difficulties to bring the equipment up and running, I turned me to support or manufacturer and that was helping me, and steps are needed to explain it to connect properly to an iMac. Actually, it is also everything so far in instructions, but unfortunately the easiest method will not function correctly. The device is indeed coupled but constantly caused transposed digits. Man must use second method and it works then also with scanning.

The guide is edited according to the manufacturer again and improved, my tip for each. Charge down the current manual from the manufacturer website and it will run everything. And if it does not work, contact the manufacturer, there is help you quickly and competently.
