(although this is generally not advisable) - see section 2.9 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.
2.9 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.
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
AdderView, press the front panel key again. A complete power off reset of the
connected keyboards and mice will then be performed. This function only resets the
shared keyboard and mice that are plugged into the control port. It does not affect
the status of any of the other ports on the switch or the CPU connections.
2.10 Hot 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.
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and
