Locking and Unlocking the Front Panel (Executive Mode)
Front panel lock mode (executive mode) disables all front panel controls, locking out the
user from those functions. Putting the switcher in this mode enhances security by protecting
against inappropriate or accidental changes to settings. When the SW USB is in lock mode,
RS-232 and contact closure remain available.
•
To lock the front panel: Press input buttons 1 and 2 simultaneously and hold them
until the red Exec Mode LED lights (approximately 5 seconds).

Press and hold simultaneously

To exit lock mode: Repeat the procedure described above. When the SW USB is no
longer in lock mode, the Exec Mode LED turns off.
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.
