Introduction
Thank you for choosing a member of the AdderView
PRO (AV4PRO) family of professional switches from
Adder Technology. There are four versions of the
four-way AV4PRO-VGA, each of which allows a single
operator to control up to four computer systems
and share peripherals among them in a very flexible
manner. The AV4PRO-VGA can support one video head
per channel, whereas the slightly larger AV4PRO-VGA-
DUAL, AV4PRO-VGA-TRIPLE and AV4PRO-VGA-QUAD
units support two, three and four video heads per
channel, respectively.
In addition to impressive VGA video performance, these
units offer more than just straight switching between
four systems. The KVM, speakers and two separate USB
devices attached to the AV4PRO-VGA units can either
be switched in unison, as normal, or you can mix your
peripherals between any of the systems to suit your
current tasks. For instance, you could be creating emails
on one system, listening to a soundtrack from another
while a third is sending documents to your printer
and a fourth performing another task with a different
USB peripheral. The AV4PRO-VGA front panels make
it straightforward to control which peripherals should
connect to each system.
The AV4PRO-VGA units feature
True Emulation
which
ensures that the full characteristics of the connected
keyboard and mouse are passed to every system.
Multiple switching
The attached peripheral devices can be
switched collectively to any computer system,
or can be linked to separate systems to
achieve multiple tasks in parallel. Multiple
switching can be controlled from the on-
screen menu or using the front panel buttons.
True Emulation
Earlier USB KVM switches relied upon
standard keyboard and mouse templates
to inform each computer system how to
deal with the connected peripherals. The
AV4PRO-VGA range succeeds in harvesting
the true identities of the connected keyboard
and mouse and presents those ‘real’ profiles
concurrently to every system. Thus, specialist
keyboards and mice can be fully supported.
Multiscreen versions
The AV4PRO-VGA range includes
separate models to support one, two,
three or four video heads per channel.
USB Remote wakeup
The USB Remote Wakeup feature is fully
supported. Any connected computer can go
into sleep mode and be awakened (when its
channel is selected) as soon as you press a
key or move the mouse. The computer and
peripherals must support the USB Remote
Wakeup feature.
Intelligent display information
The AV4PRO-VGA units use our
EDID Emulation
feature to ensure
that all computers are supplied with
the correct information about each
connected video display.
