VGA EXTENDER, VGA EXTENDER WITH AUDIO
4. Operation
Once the VGA Extender is installed, monitor the extender’s operation via its LEDs.
Also, use the equalizer selector switch to adjust the VGA signal for various cable
lengths and characteristics.
4.1 LEDs
There are two LEDs on each unit. On the local unit, the Power LED lights when
proper power is supplied to the unit. The Active LED lights when the extender
detects a VGA input signal.
On the remote unit, the Power LED lights when the unit is properly powered. The
Active LED lights when the extender properly decodes VGA signals for the two
local HD15 VGA ports. If the AC556A
-R2
is used to transmit audio signals only, the
Active LED never turns on.
4.2 Equalizer Selector Switch
Adjust the equalizer selector switch on the remote unit (labeled
