4. Installation

Switch OFF all computers and USB devices to be connected. Connect the computers and USB
devices with suitable cables. The computers connect to the USB type B sockets found on the
AutoSwitch. Please note that cheap USB cables si milar to those found on USB mice are not
suitable for use with the AutoSwitch. Poor quality cables may cause transfer problems and
eventually lead to the loss of data!

If you intend to connect any high-speed USB 2.0 devi ces, then it is important that you use high
quality USB 2.0 cables. Poor quality cables can usually be recognized by their smaller cable
diameter compared with high quality USB 2.0 cables. The maximum cable length at each input
