Operation
In operation, the AdderView Secure unit allows you to quickly and securely
switch between up to four systems. Strictly only one system may be accessed at
a time, whereupon the common keyboard and mouse are linked to that system.
Tamper-evident seals
Given the high security nature of most installations that incorporate this unit,
it may be a policy of your organisation to fit tamper-evident labels across
certain seals and/or chassis screws. As part of a best practice policy, you are
recommended to check any applied seals on a regular basis to ensure that the
unit has not been opened without authorisation.
Selecting computers
In order to guard against the possibility of malicious software and also to
minimise the chance of accidental switching, the AdderView Secure unit offers
only one method to change between channels. All switching is done using the
front panel switches.

• The buttons are clearly labelled to eliminate any ambiguity.
• Press the appropriate button to select the labelled channel.
• When the chosen channel has been connected, the adjacent indicator
will illuminate (continuously) to confirm. If the indicator flashes, then the
selected computer is either switched off or disconnected.
• Each channel uses a differently coloured indicator to provide additional visual
feedback about the chosen channel. Channel 1 has a green indicator and
is generally configured to link with the lowest security computer/network,
whereas channel 4 (or channel 2 on two-port versions) has a red indicator
and is generally configured to link with the highest security computer/network.

Error indicator
The red error indicator is located on the right side
of the front panel and is labelled ERR. Separate
microprocessors monitor each channel and any
of them can trigger an error state if they detect
unexpected or unauthorised operations. If the ERR
indicator illuminates, you will need to first locate and
confirm the source of the fault. Then you will need to
either power cycle the offending computer or remove
and replace its USB connection to the AdderView
Secure.
Smart card reader
AdderView Secure models with an optional smart card reader which allow you
to insert your security card for authorisation. The instructions given here are
general advice and may be
superseded by procedures
stipulated by your
organisation.
Note: The channel can be
changed before or after
inserting the smart card.
To use the smart card
reader
1 Align your smart card
with the reader slot,
located in the front panel
of the unit. Ensure that
the gold contacts of the
card are facing down.
2 Press the required
channel select button (if
the required channel is
not already selected).
3 Follow the on screen
instructions issued by the
selected computer.
