SmartView Multiscreen Installation and Use Page 18
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 SmartView 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 SmartView 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 SmartView 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 SmartView 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 SmartView 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 SmartView 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
SmartView 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 SmartView Multiscreen detects that the mouse has been
disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse
and the SmartView Multiscreen will re-initialise it.
Alternatively you can reset the keyboards and mice by holding down the front panel
key for 5 seconds. When the character ‘C’ is displayed on the front of the SmartView
