Active USB LEDs:
d
Input LEDs — Each of these LEDs lights when a host or PC is
connected to the switcher’s corresponding USB input port and
is detected by the SW USB, regardless of whether the input is
currently selected.
e
Output LEDs — Each of these LEDs lights when a peripheral
device is connected to the switcher’s corresponding output port
and has been enabled by the selected input device or host PC.
Operations
Powering on the switcher
To power on the SW USB,
1
. Connect all input and output devices to the switcher’s rear
panel connectors and, if desired, connect a host PC to the
RS-232 port. (See chapter 2, “Installation,” for information
on the rear panel connections.)
2 . Plug the power supply into the two-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
sequence from left to right. If the self-test completes with
no errors, the LED for the most recently selected input
remains lit.
3 . Select input 1, and power up the PC connected to input 1.
4 . Repeat step 3 for all remaining inputs to which PCs are
connected.
Selecting an input
SW USB inputs can be selected by using:
•
The front panel buttons
• Contact closure
• SIS commands
Selecting an input from the front panel
To select an input from the front panel, press the desired input’s
button. The LED corresponding to the selected input button
lights.
After an input is selected, the LED remains lit until a new input
is selected.
