Figure 3 — VSC 75 front panel

Adjustments to front panel features and controls do not affect the local monitor.

1Power/signal lock LED — If this indicator...

•Lights amber yellow without blinking, the VSC 75 is receiving power, but no input signal is present.

•Blinks green, the unit is receiving power, but the input signal has a resolution that is too low or too high.

•Lights green without blinking, the input signal is within range, and the VSC 75 has locked to that particular resolution.

2Freeze button and LED — Press this button to display (or record) a still image of the scan-converted picture from both display outputs. The freeze indicator LED lights while this control is active. To turn this feature off, press the Freeze button again. Freeze affects both outputs simultaneously. The image on the local monitor will not be frozen.

The LED lights to indicate that the freeze feature is active.

All controls except Freeze will be locked on the front panel while freeze mode is active. Press the Freeze button again to turn off freeze mode and unlock the other controls.

2+ 6 Executive mode release (Freeze + Size) — Press

the Freeze button and the Size button simultaneously for 2 seconds to release executive mode. Executive mode, which can be activated only by issuing an RS-232 command (see page 3-5), prevents unauthorized or accidental adjustments to the VSC 75’s settings via front panel controls by locking all the front panel features except centering

controls. Adjustments can still be made via RS-232 control when executive mode is active.

3Test button and LED — Press this button to display a color bar test pattern on the output devices. The test indicator LED lights while this control is active. The test pattern continues to be displayed until you press the Test button again.

This LED lights to indicate that the test feature is active.

4Flicker filter button — Press this button to choose one of the two levels of vertical filtering. Select the setting that yields the least amount of flicker.

5Flicker filter LEDs — These LEDs light yellow to indicate the selected level of vertical filtering.

6Size button and LED — Press this button to activate the size feature. When Size is active, the picture can be resized vertically and/or horizontally by rotating the vertical and horizontal Centering/Pan/Size rotary controls (10). Observe the picture on screen as you adjust the controls. To zoom in, adjust the size so the picture exceeds the screen’s limits. The Min/ Max LED (11) lights red when the minimum or maximum limit of a control has been reached.

The LED lights green to indicate that the size feature is active.

The size feature affects both display outputs simultaneously. The local monitor loop-out is not affected.

The size feature remains active for 8 seconds after the rotary controls become inactive. The rotary controls then default to the standard centering and pan functions. To turn the size feature off, press the Size button again.

See Freeze button (2) for information on using executive mode.

7Vertical () and horizontal () Centering/Pan/Size rotary controls — Turn these knobs to adjust vertical or horizontal centering (when the image size does not exceed the screen size) and panning (when the image size exceeds the screen size) in the regular mode. Rotate these controls to adjust picture size when the size feature is active.
