Power connection
When you are ready to apply power to your SW8/12 VGA Ars unit, connect the
female end of the power cord to the AC outlet at the left edge of the rear panel,
and connect the male end of the power cord to a 120/240 VAC power outlet.
When power is applied all front panel LEDs light for one second, then go out.
The LED for the previously selected input then comes on and remains lit until the
current input is de-selected.

Figure 2-7 Video input connectors
SW8/12 VGA Ars switchers monitor each input port for the presence of a
horizontal sync pulse, which indicates the presence of a video signal. When
detected, the video signal’s presence is reported on the switcher’s RS-232 control
port. See chapter 3, “Operation and Control” for information on the Simple
Instruction Set (SIS ™ ) commands which can be used to communicate through the
RS-232 port.
The SIS command 0S requests the switcher to report the status of all inputs at once.
The SIS command xS requests the status of specific port “x”.
