2.7 Other useful installation information
Intelligent cables – The USB and Sun cables contain miniature active circuits that are moulded into the ends of the cable assembly. These circuits intelligently provide signals to your computers that make them think that a keyboard and mouse are continuously attached, even if the AdderView is not connected or powered on. This increases the reliability and robustness of the installation.
PC boot up sequence - When your PCs are powered on they communicate with any attached keyboards and mice and setup parameters required by the particular operating system.

Mouse characteristics - do not unplug a PS/2 mouse connection from a PC whilst the PC is on. Due to the design of PS/2 mice communications the mouse function on the PC will be lost and you will have to
Keyboard and mouse mode switching - The AdderView keeps a log of the keyboard and mouse mode and resolution settings requested by each of the connected PCs. These settings are automatically restored to the shared keyboard and mouse when the AdderView channel is switched thus ensuring maximum software compatibility. The keyboard num, caps and scroll lock states are an obvious example of this process.
2.8Hot plugging the AdderView into running systems and re- enabling disconnected CPU PS/2 mouse connections
It is adviseable to switch off the systems that are going to be connected to the AdderView before installation. However if this is not possible then most systems can be hot plugged by using the AdderView’s mouse restoration functions. The keyboard connection will normally restore itself automatically.
