The US221A / US421A is a 2/4-port USB 2.0 Peripheral Switch that allows up to 2/4 computers to share the use of a
single USB peripheral device (such as a printer, scanner, mass storage drive, etc.) on a one-at-a-time basis.
The peripheral focus can be given to a computer manually by using pushbuttons on the switch, using the software-
based conguration utility, or by the Auto Switch function.
Compatible with both Windows and Mac, and with multifunction printer support, the US221A / US421A is the ideal way
to share the latest USB 2.0 peripherals in a multimedia ofce environment.
