USB
■ USB 2.0 compatible – Supports 480 Mbps high speed
communications and is backwards compatible with all prior USB
versions.
■ Four port output hub –Allows simultaneous connection to multiple
peripheral devices such as mass storage devices, keyboards, mice,
or other HID – Human Interface Devices. Attached devices can be
powered via the 5V, 500mA current provided on each output.
■ Port Status LEDs – Provides visual indication of port activity for
enumerated peripherals and all connected and active host devices.
■ Multiple control points – Operation via front panel, RS-232, and
contact closure offers integration flexibility into a variety of control
environments.
■ RS-232 pass-through – Reduces RS-232 control port requirements
by processing SIS commands within the SW USB while also passing
them through to other controllable Extron video switchers.
■ Front panel security lockout – Prevents unauthorized use in non-
secure environments. In lockout mode, a special button combination
is required to operate the switcher from the front panel controller.
■ Host and Peripheral Emulation Mode – SW4 USB Plus model –
Offers increased system reliability by emulating uninterrupted
connection between host and keyboard/mouse devices. This
selectable feature enables devices to “keep alive” when switching
between inputs.
■ Rack-mountable 1U, half rack width metal enclosure
■ External universal power supply included
The SW USB Series are two- and four-input USB switchers that provide
integrator-friendly solutions for implementing USB 2.0 compatible
switching in today’s A/V environments. A number of specialized
features help further streamline integration, such as: port status
indication, RS-232 pass-through, front panel security lockout, and
multiple control points.
All of the SW USB Series switchers act as active USB hubs, supplying
5V, 500mA to attached devices, per USB specification. In addition, the
switchers are USB 2.0 compatible, and are backwardly-compatible with
all previous USB data rate specifications, including low speed 1.5 Mbps,
full speed 12 Mbps, and hi-speed 480 Mbps.
RS-232 pass-through reduces RS-232 control port requirements by
processing SIS commands within the SW USB while also passing them
through to other controllable Extron audio and video switchers.
The SW4 USB Plus model features Host and Peripheral Emulation Mode,
which provides “keep alive” functionality by continuously mimicking
host and keyboard/mouse device communications within the switcher.
This emulation eliminates the need for enumeration, and reduces the
chance of failed device communications throughout the switching
process.
The SW USB Series incorporates rack mountable, 1U, half-rack width
enclosures for simplified integration. All models include an external,
universal power supply for worldwide power compatibility.
SW USB with Interactive Whiteboards
Extron’s SW USB switchers are well suited for implementation
in interactive whiteboard applications for both corporate and
education environments. These popular applications will benefit
from the high number of integrator-friendly features, offering
streamlined design capabilities and increased reliability.
Simplified operation and control
• Variety of control locations offers exibility and convenience –
Front panel and contact closure for operation in the most basic
systems and full RS-232 integration through MediaLink, IP Link,
or other third party control systems.
• RS-232 pass-through offers increased exibility, allowing other
Extron controllable switchers to be incorporated into designs
that require additional signal switching.
System reliability
• Host and peripheral emulation in the SW4 USB Plus provides
“keep alive” functionality by continuously mimicking host and
keyboard/mouse device communications within the switcher.
This emulation eliminates the need for enumeration, and
reduces the chance of failed device communications throughout
the switching process.
• Port Status LEDs provide real-time visual indication of
connectivity and operational state of attached hosts and
peripherals
