About the SW USB Series

The SW USB Series switchers make it possible for two or four host computers to share and

and device emulation, so that connections are maintained between host computers and
peripherals.

A number of specialized features help to streamline system integration, including port status
indication, RS-232 pass-through, front panel security lockout, and multiple control points.
