Selecting an Input

SW USB inputs can be selected by using:
•
•
•
•
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
"Installation" section 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" in the "Installation" section for more information).
If desired, connect a host PC to the RS-232 port (see
Communication" in the "Installation" section).
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").

Using a contact closure device: If a two- or four-button contact closure device is
connected to the SW USB Contact port, press the button on the device that 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.
Using a jumper wire: On the Contact port, use a jumper wire to connect the
ground (_) pin to one of the other pins in the Contact connector (the ground [_] pin is
pin 3 for SW2 and pin 5 for SW4 models). Connecting pin 1 to ground selects input 1,
pin 2 selects input 2, and so forth.
Using an IR 102: See the IR 102 User's Manual to use the IR 102 with a switcher.
