- USB 2.0 compatible - supports 480 Mbps High Speed communications and is backwards compatible with all prior USB versions
- Four port output hub with 5 V, 500 mA available on each output - allows simultaneous connection to multiple peripheral devices such as mass storage devices, keyboards, mice, or other HID
- 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
- Rack-mountable, 1U half rack width metal enclosure
- Energy-efficient external universal power supply - provides worldwide compatibility, low power consumption, and reduced operating costs
- Host and peripheral emulation mode - offers increased system reliability by emulating uninterrupted connection between host and keyboard/mouse devices
The Extron SW4 USB Plus is USB switcher that allows switching between multiple host devices and multiple USB peripherals. It provides integrator-friendly solutions for implementing USB 2.0 compatible switching in professional AV 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. The SW4 USB Plus model features host and peripheral emulation mode, which provides "keep alive" functionality by continuously mimicking host and keyboard/mouse communications within the switcher. This emulation eliminates the need for enumeration, and reduces the chance of failed device communications throughout the switching process.
All of the SW USB series switchers act as active USB hubs, supplying 5 V, 500 mA to attached devices, per USB specification. In addition, the switchers are USB 2.0 compatible, and are backwards 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 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.
