Selecting an input from the front panel
To select an input from the front panel, press the desired input button. The LED adjacent to
the button lights. After an input is selected, its LED remains lit until a new input is selected or
the SW USB is powered off.
Selecting an input using contact closure
Use one of the following methods to select inputs on the SW USB and the AV switcher
(if connected) using contact closure (see
page 12 for connection information):
•
Input LEDs — Each of these green LEDs lights when a host or PC is connected to the
corresponding USB input port on the switcher and is detected by the SW USB, whether
or not the input is selected.
Output LEDs — Each of these green LEDs lights when a peripheral device is
connected to the corresponding output port on the SW USB and has been enabled by
the selected input device or host PC.
Connect all input and output devices to the rear panel connectors on the switcher (see
Rear Panel Features
on page 7 for more information).
If desired, connect a host PC to the RS-232 port (see
Communication
on page 11).
Plug the power supply into the 2-pole captive screw power connector on the rear panel.
The unit performs a self-test, during which the Exec Mode LED and the front panel Input
LEDs each blink once in succession from left to right. If the self-test completes with no
errors, the LED for the most recently selected input remains lit.
Select each input and power up the host device connected to it (see
Input
on page 16).

corresponds to the SW USB input that you want to select. The first button on the left
selects input 1, the second button selects input 2, and so forth.
