Audio Hold
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.
Status display
The secure nature of the switch entails that all USB
communications are uni-directional. This means that the
keyboard num, caps and scroll lock indicators will not work.
Therefore, the secure switch provides such indications on the
optional remote control unit.
The status display also shows the current channel number; the channel from which audio
is being derived and also the remote control unit status.
Operation
The secure multi-viewer switch allows the user to view the video outputs of up to four
host computers simultaneously, either on a single display or dual displays. Keyboard and
mouse control is assigned to a single host computer at a time and is switchable using a
number of methods (see page 19).
