To connect the tiptoi pen with a computer, it is not necessary to use a special cable. The tiptoi pen generally works via the tiptoi Manager application, which must be downloaded and installed on the computer. Make sure that the computer meets the system requirements, such as an x86-compatible Intel processor, Windows or Mac OS X, and an Internet connection. If you have any problems, check that the pen is switched on and that the batteries are inserted correctly. In the event of automatic disconnection, disconnect the pen briefly and then reconnect it.
