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.)

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.
N
The 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
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.
