2.9 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 LINDY CPU Switch Multiscreen 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 re-boot the PC to regain normal operation.
Unplugging the mouse from the LINDY CPU Switch Multiscreen will also cause it to
stop operating when it is plugged back in. RS232 mice can usually be unplugged
and plugged back in provided that a mouse was connected when the operating
system initially booted. The LINDY CPU Switch Multiscreen is fitted with a PS/2
mouse recovery system which allows you to disconnect and re-connect the shared
mouse without powering down the system (although this is generally not advisable) -
see section 2.10 for details.
Keyboard and mouse mode switching - The LINDY CPU Switch Multiscreen
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 LINDY CPU Switch Multiscreen channel is switched
thus ensuring maximum software compatibility. The keyboard num, caps and scroll
lock states are an obvious example of this process.
2.10 Re-enabling a disconnected PS/2 mouse
If you disconnect the shared PS/2 mouse from the LINDY CPU Switch Multiscreen
by accident during operation then the mouse operation will be lost when the mouse
is plugged back in. To avoid having to reboot the entire system in this situation the
LINDY CPU Switch Multiscreen is fitted with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the keypad or
keyboard hotkeys. The LINDY CPU Switch Multiscreen detects that the mouse has
been disconnected and triggers the automatic recovery system. Plug in the PS/2
mouse and the LINDY CPU Switch Multiscreen will re-initialise it.
Alternatively you can reset the keyboards and mice by holding down the front panel
