3. DIP switches
The K4u
+
has a two sets of DIP switches fitted to the underside
of the case. A label alongside these switches indicates the
function of each switch. This section describes the individual
switches.
A1 and A2: Set Hot-key Combination
Factory default: A1=OFF, A2=OFF
These switches define the hot-key combination. This is two
pre-assigned keys which, when held down together with a
third key, activate a special feature of the K4u
+
switch. The
factory default hot-key combination is Alt + Space. Three
alternative combinations are listed on the configuration label
on the underside of the unit.
Hot keys are described in section 4.
A3: Mouse Channel Changing
Factory default: A3=ON
When A3 is ON, users can change channel focus by clicking
the mouse buttons.
To change channels, hold down the centre mouse button.
Then click the left or right mouse buttons to scroll around
the channels. See section 7.1.3.
A4: Audio Mix / Switch
Factory default: A4=ON
When A4 is ON, the K4u
+
mixes all four stereo audio inputs
through to the single output on the front of the unit,
regardless of the focused channel. When A4 is OFF, the audio
output follows the keyboard and mouse focus, switching
channels when the focus changes.
Audio switching and mixing are described in section 7. 3.
A5: Active Sensing
Factory default: A5=ON
When A5 is ON, the K4u
+
only switches to channels that have
an active computer attached (ie, connected and powered). It
will not switch to empty channels and skips them when a
user changes channels using the mouse.
A6: Confirmation Beeps
Factory default: A6=ON
When A6 is ON, the K4u
+
gives a confirmation beep
whenever there is a change of state (eg, a channel change or
some other hot-key function has been invoked).
Even when A6 is OFF and confirmation beeps are disabled,
the switch still gives warning beeps eg, when the unit resets
or when a new keyboard is plugged into the front of
the K4u
+
.
A7 and A8: Sun™ / USB Keyboard Country Layout
Factory default is country specific.
For users with a Sun workstation but a non-country layout
reporting keyboard (this includes PS/2 and most USB
keyboards), these switches inform the Sun workstation of
the layout of the attached keyboard.
B1 and B2: Shared Channel Selection
Factory default: B1=OFF, B2=OFF
If a computer is shared between two K4u
+
switches, use B1
and B2 to specify which channel is shared.
When a K4u
+
(with keyboard and mouse attached) detects
that a second K4u
+
has been connected to one of its front
panel USB ports (A to D), it automatically enables sharing
mode. This allows two users to share the computer on the
channel specified by B1 and B2.
Channel sharing is described in section 7. 7.
B3 and B4: Sharing Timeout
Factory default: B3=OFF, B4=ON
If a computer is shared between two K4u
+
switches, use B3
and B4 to specify the sharing timeout. The timeout can be
from zero to 10 seconds.
When a shared computer is being controlled by a user,
the other user is automatically blocked from accessing it.
If the shared computer is left unused, it remains locked to
the controlling user until the timeout expires. The shared
computer then becomes available to either user. See
section 7. 7 for details.
