LOCAL UNIT OPERATION

5.2 Operation of Dual Access Local Units
Models ACU1009A, ACU1008A and ACU1005A offer dual access with a second console at
the Local Unit. This operates on a first-come, first-served basis. When one console is in use,
the system blocks out the other console until there is no keyboard or mouse use at the active
console for a set time: the
Inactivity Timeout Period . Thereafter, any keyboard (and,
optionally, mouse) action at the other console switches console activity.
Inactivity Timeout Period
You can set the Inactivity Timeout Period to 2 seconds (the default) or 15 seconds using
switch 2 on the SW1 DIP switch block on the Remote Unit’s main circuit board (see Figure
13).
Console Switching Method
Switch 3 on the same block (see Figure 13) determines the method of switching between
consoles. The default method uses any detected keyboard action only. By moving switch 3 to
the OFF position, the system will also switch consoles if there is any detected mouse
movement at the inactive console.
When the PC is booted, the local console is active.
When you are activating a console, the first key or mouse press is not passed
to the PC.
ACU1008A only: Serial communication across the Extender system
continues even when the local console is active or in a Private Mode session.
Scroll Lock Function
The Remote Unit supplied with ACU1009A and ACU1008A systems redefines the function
of the Scroll Lock key (on both the local and remote console keyboards) for system use (see
page 32).
You can restore normal Scroll Lock activity by setting switch 4 on the SW1 DIP switch block
on the Remote Unit’s main circuit board to ON (see Figure 13). In Dual Access systems, this
will disable Private Mode operation. In addition, if you need to reset/recover a console’s
keyboard and mouse, you may need to reboot the CPU or repower the Remote Unit.
SUN versions: ACU1005A uses key combinations for system commands (see page 33).
Switch 4 on the SW1 DIP switch block is not used.
