SW USB Series • Operation 17
Resetting
To reset the switcher to its factory default settings from the front panel:
1. Disconnect power from the SW USB.
2. Press and hold the Input 1 button while reapplying power to the unit.
The Input LEDs blink three times to indicate that a reset has occurred. The input selection
defaults to input 1, and the Input 1 LED lights.
Host Emulation (SW4 USB Plus Only)
The SW4 USB Plus model provides host emulation to peripheral devices on two of its output
ports. If a keyboard, mouse, or both are connected to output port 3 or 4, and the Host
Emulation DIP switches are set to On, the SW USB emulates a host PC to the connected
peripheral device. The keyboard or mouse connected to port 3 or 4 still responds as if it were
attached directly to the computer on the selected input.
Host emulation allows instant communication of the emulated ports when the SW USB
switches to another input, by eliminating the delay that normally occurs while a computer
recognizes a new device and establishes communication with it.
Setting up for host emulation
To enable host emulation:
1. Connect a keyboard, a mouse, or both to output port 3, 4, or both. The SW4 USB Plus
can emulate a keyboard and a mouse simultaneously. Either type of device can be
connected to either or both of the two emulation ports (3 and 4).
NOTE: The SW USB can emulate a host through ports 3 and 4 if a hub or an
extender with an internal hub is connected to either of these ports. Only a
single hub or extender is supported. If a second hub or a second extender is
connected, host emulation is disabled on one of the ports.
2. Place the Host Emulation DIP switches on the rear panel in the appropriate position to
enable emulation for the connected device. The table below shows the switch positions
for keyboard and mouse emulation.
Switch 1 (Mouse) Switch 2 (Keyboard) Emulation
Off (down) Off (down) No emulation
On (up) Off (down) Emulate mouse only.
Off (down) On (up) Emulate keyboard only.
On (up) On (up) Emulate keyboard and mouse.
Example: In the illustration at right, the DIP switches are set to enable
emulation of both a mouse and a keyboard (up).
