SECTION II
OPERATING INSTRUCTIONS
2 1 INTRODUCTION
This section contains the general operating instructions and procedures for the Model
NVVN621 Video Marker.
2.2. INSTALLATION AND OPERATION
Connect a camera or other source of a composite video signal to the “input” connector on the
rear of the NVVN621. Connect a composite video monitor to the “output” connector.
Connect the coaxial power input to a regulated 5VDC, >900mA, (12VDC for “Opt-12 models)
center pin positive power source. The “Run” LED should appear steady and the “Setup” LED should
flash for about ten seconds while the unit boots. About two seconds after booting, the unit should
function according to previously saved settings.
Run/Setup: The Video Line Generator can be toggled between two modes of operation by
means of the Run/Setup button. Push the button briefly to change modes. In the Run Mode, all other
controls are locked. Controls are active in the Setup Mode. Either mode can be used indefinitely.
Adjustment: The Video Line Generator superimposes four lines. Each line's position is
independently adjustable. The two vertical lines can be tilted about a pivot point at the bottom of the
display.
To adjust the characteristics of the lines, place the Video Line Generator in “Setup” mode by
pressing the “Run/Setup” button until the “Setup” LED is illuminated.
The horizontal or vertical positions of the lines can be individually set by turning one of the
position knobs.
The lines can be set to black, white, or off by pressing the “Color” button to step through the
available colors until the desired color is displayed.
Vertical Lines can be tilted. Turn the tilt knob to obtain the desired angle.
The unit can be left indefinitely in the “Setup” mode to allow the controls to remain active. Use
the “Run/Setup” button to toggle to “run” mode in order to make the controls inactive.
Settings can be saved in order to preserve them while power is absent. While the unit is in
“setup” mode, press and hold the “Run/Setup” button. Release the button once the “Setup” LED has
extinguished. Settings will be saved until this process is repeated for new settings.
