A

Auto Switch Active LED — This LED lights when

autoswitching is enabled. See “Enabling autoswitching”

in chapter 2, “Installation,” for the procedure to set up

autoswitching.

B

IR receiver port — This sensor detects IR signals from the

optional IR 102 at a distance of up to 30 feet, and within 40

degrees off the axis. (See “Using the IR 102 remote control,”

later in this chapter, for more information.)

C

Input Selection buttons and LEDs — Press these buttons to

select inputs 1 and 2 or 1 through 4. The LED at the right of

each button lights when the corresponding input has been

selected.

D

Input EQ DIP switches — These DIP switches (one for each

input) set the equalization for the corresponding input. (See

“Setting equalization for input sources,” later in this chapter.)

E

Signal Presence LEDs — Each of these LEDs lights when a

signal is present on the corresponding input.

Operations

Powering on the switcher

To power on the SW2/SW4,

1. Connect all input and output devices to the switcher’s rear panel connectors. (See chapter 2, “Installation,” for information on the rear panel connections.)

2. Power on the display.

3. Plug the power supply into the orange 2-pole captive screw power connector on the rear panel.

•The unit performs a self-test, during which the front panel Auto Switch and Input LEDs 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.

•The switcher reads the EDID information from the connected output device and writes it to non-volatile memory on each input.

NThe EDID information is also read and stored again whenever power is recycled to the output device or the output device is replaced. You must reboot your computer and other input devices in order for them to read the new information.

4. Power on the input devices.

Selecting an input

To switch an input to the output, press the desired input’s button on the front panel. The LED corresponding to the selected input button lights.

•After an input is selected, the LED remains lit until a new input is selected.

•To determine the current configuration, check the front panel input LEDs. The one that is lit indicates the selected input.

•Only one input can be switched to the output at a time.

You can also select an input using SIS™ commands (see chapter 4, “SIS Configuration and Control,”) or IR remote control (see “Using the IR 102 remote control,” in the next section). Front panel input selection is disabled when autoswitching is in effect.
