Power LED — This LED lights when the SW USB has power.

Exec Mode LED — This LED lights when the SW USB is in

executive mode, indicating that the front panel is locked and

commands cannot be entered through it.

Input Selection buttons and LEDs — Press these buttons

to select inputs 1 and 2 (SW2) or 1 through 4 (SW4 and

SW4 Plus). The LED at the right of each button lights when the

corresponding input has been selected.

These buttons also can be used to initiate executive mode and

to reset the unit. See “Enabling front panel lockout (executive

mode)” and “Resetting,” later in this chapter.

Active USB LEDs:

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.

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.
