Setting front panel switches
Set the front panel switches before cabling and testing inputs.
These examples will show 2-gang size interfaces, but they apply
to both 2- and 4-gang sizes and to the EC models.
Front panel features — RGB 500 series, RGB 508 series
1 Horizontal shift knob — Use this knob to adjust the horizontal
sync to move the picture left or right to center it each time the
interface is powered on.
The horizontal shift control has no mechanical limits to
rotation. When the minimum or maximum limit of the
control is reached, the picture ceases to move on screen.
2 Power indicator LED — The RGB 500 Series interfaces have a
built-in autopower feature. When a signal is present at the
input, the interface will power on, and the green front panel
LED will light.
3 Audio input connector — Use this 3.5 mm stereo jack to connect
an unbalanced audio source to the
interface. Wire the plug as shown at
left.
4 Video input termination toggle switch — The toggle switch on
the front panel allows you to select video input impedance that
provides the best picture.
• Set this switch to High Z if a local monitor is connected, a
laptop breakout cable is used, or if the picture is too dark.
