2.11 Other useful installation information
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. It is necessary for the AdderLink to be attached and powered on during this sequence so that it can give the required responses and keep track of all the modes and settings requested by each of the connected PCs.
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 AdderLink keeps a log of the keyboard and mouse mode and resolution settings requested by the connected PC(s). These settings are automatically communicated to the keyboard and mouse as required to ensure maximum software compatibility. The keyboard num, caps and scroll lock states are an obvious example of this process.
2.12Hot plugging the AdderLink 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 AdderLink before installation. However if this is not possible then most systems can be hot plugged by using the AdderLink’s mouse restoration functions. The keyboard connection will normally restore itself automatically.
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and plugged back in whilst the PC is running. Mouse movement can then only be restored by rebooting the PC. This is because the mouse drivers only setup and enable the mouse when the PC is initially booted.
If you have switched off your AdderLink or you are attempting to ‘hot plug’ it into a system that is already running, you may be able to restore lost mouse movement using the AdderLink's mouse restoration functions.
