Connections
Operation
Connect all peripherals and computers to the KVM unit. Ensure that the video monitor(s) are
switched on before powering on the KVM unit.
Switching between computers
Select a computer by either moving the mouse between channel windows, using an RCU or the front
panel buttons (AVS-4224 only). The console peripherals will be switched to the chosen computer and
the corresponding indicator will illuminate.

Audio Hold
(for model AVS-4224)
The Audio Hold button prevents switching the audio port when changing the other console
peripherals (keyboard, mouse, video) to another computer channel. This function is useful when you
need to listen to the audio from one computer while working on another.
Using the front panel computer channel buttons, first connect the console peripherals to the computer
from where the audio feed is required. Press the Audio Hold button on the front panel. Then press the
channel button for the computer that is required for the other peripherals. The audio association will
be signalled by the right indicator on each channel’s front panel push button.
To release the audio from hold status, press the Audio Hold button again.
Power on self-test
When the unit powers up it performs a self-test procedure. If the self-test fails for any reason, including
a jammed button, the unit will become inoperable. The front panel indicators will show an abnormal
display. Contact technical support and avoid using the product.
Remote control unit
The RCU provides a way to manually switch
computer channels when the Adder unit is
located away from your desktop. The RCU
connects to the rear panel of the main unit
and replicates at least the channel buttons.
Communications are based upon the
standard RS232 protocol.

RCU Splitter
The AVS-42216 is controlled by two
8-port Adder RCUs (AS-8RCU) that
are connected using an Adder RCU
Splitter (AS-SPLRCU) to the remote
control port of the switch.
The first RCU is used to select ports
1-8 and the second one, ports 9-16.
