Installation and Use

2.6 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 ADDERview 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 ADDERview 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 ADDERview 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 2.7 for details.
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.
2.7 Re-enabling a disconnected PS/2 mouse
If you disconnect the shared PS/2 mouse from the ADDERview 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 ADDERview is fitted
with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the keypad or
keyboard hotkeys. The ADDERview detects that the mouse has been disconnected
and triggers the automatic recovery system. Plug in the PS/2 mouse and the
ADDERview will re-initialise it. You may also re-enable a disconnected PS/2 mouse
by using the keyboard and mouse reset function (see section 3.7). This function
powers down and resets the shared keyboard and mouse whilst the rest of the
ADDERview operates normally.
