13 Vertical ( ) and horizontal ( ) Centering/Pan/Size

rotary controls — Turn these knobs to adjust vertical or

horizontal centering (when the image size does not exceed

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 mode is active.

14 Min/Max LED — This lights red when the minimum or

maximum limit of a control (13) has been reached.

15 Burst Lock (genlock) LED — This lights green to indicate

that the VSC 150 is receiving a genlock (black burst) sync

signal via the rear panel genlock input connector. Genlock

is a sync timing reference signal used to synchronize an

entire system’s components. If this LED does not light

when genlock is active, then either further phase

adjustment is needed, or a different, more stable or time-

base-corrected sync signal must be used for the genlock

source.

16 Horizontal phase (Horz Phase) control — During genlock

setup use a small screwdriver to rotate this control to align

the horizontal phase of the composite video sync signal

with that of the genlock signal. See “Setting Up Genlock

and Vertical Interval Switching” in this chapter for details.

17 Subcarrier phase (Sub Phase) control — During genlock

setup use a small screwdriver to rotate this control to align

the color subcarrier phase of the composite video sync

signal with that of the genlock signal. See “Setting Up

Genlock and Vertical Interval Switching” in this chapter for

details.

1AC power input connector — Connect a standard IEC AC power cord here for power input (100VAC to 240VAC, 50/60 Hz).

2VGA computer input/Macintosh local monitor output connector — Connect a VGA-type computer to the VSC 150 via this 15-pin D connector (and the provided Mac-VGA cable) to use a VGA-type computer as the video signal source.

If a Macintosh, instead of a VGA-type PC, is used as a source, this connector serves as the Mac local monitor pass- through output connector.

3Macintosh (Mac) input/VGA local monitor output connector — Connect a Macintosh computer to the VSC 150 via this 15-pin HD connector (and the provided Mac-VGA cable) to use a Mac as the video signal source. If a VGA/SVGA-type computer, instead of a Macintosh, is used as a source, this connector serves as the VGA local monitor pass-through output connector.

4DIP switches — These two switches select the signal standard (NTSC or PAL) applied to the scan converted video output, and the video input termination (75 ohm or high impedance).

1 — PAL Out — Select the output standard with this switch. This switch affects both of the display outputs (composite video and one other), but not the local monitor.

ON — The output is in PAL (Phase Alternate Line) format (625 lines/frame at 50 Hz vertical, 15.625 kHz horizontal).

OFF — The output is in NTSC (National Television Standards Committee) format

(525 lines/frame at 60 Hz vertical, 15.734 kHz horizontal).
