Extron SW4 USB Plus (part number 60-954-01) - a 4-input USB 2.0 switcher with host and peripheral emulation for USB links that need to stay connected through a switch.

Standard USB switchers force devices to re-enumerate on every change, which can drop mice, tablets, or annotation devices mid-session. The SW4 USB Plus adds an optional emulation mode that continuously mimics host and keyboard/mouse communication inside the switcher, so connected peripherals see a stable link even while inputs change. Two built-in hubs and RS-232 pass-through round out a design meant for demanding shared-control rooms.

Key Capabilities

• 4 USB type B host inputs switched to a shared 4-port USB hub
• Optional host/peripheral emulation mode to prevent dropped enumeration
• Two built-in USB hubs versus one on the standard SW4 USB
• 500 mA of shared power across the four output ports
• RS-232 control with RS-232 pass-through for AV control chains
• 1U half-rack metal enclosure at 2.0 lbs
