Series Switcher” in the “Reference Information” section).
2. Connect host devices to one or more SW USB Switched Input type B connectors, using
cable lengths of up to 15 feet (4.5 m).
3. Connect one or more peripheral USB devices to the SW USB Output Hub type A
connectors, using USB cable lengths of up to 15 feet (4.5 m).
4. (Optional) Connect an RS-232 cable between the SW USB RS-232 port and a host
computer or control system (see “Wiring for RS-232 Communication” on page 8).
NOTE: The computer that you use for RS-232 control should not be one of the
host devices connected to any of the input ports.
