3.3 Operating the DV2000

Power on
When power is first applied, the DV2000 will boot its operating system and will then run its
DV2000 application program. This process takes about 15 seconds. After the application
program has started, a DV2000 status screen will appear at the VGA output; nothing appears
at the monitor output other than the video source which is connected to the monitor input.
Menus / cursor keys
Front panel control of the DV2000 is accomplished using the cursor keys and on-screen
menus. The menus appear at the monitor output BNC and/or the VGA output. Pressing
brings-up the main menu. Pressing the left and right arrow keys brings you to other
ENTER
menus. Pressing the up and down arrow keys allows you to scroll through choices within a
menu. Pressing within a menu allows you to make changes to settings. Every menu
ENTER
screen has help messages to guide you.
Settings
Many aspects of the DV2000 may be customized by way of user settings. One example of a
setting is closed caption waveform amplitude—the user has the ability to set the waveform to
compensate for video sources that may, or may not, have 7.5 IRE pedestals added. Settings
are made from the front panel, or they may be done via a script file, network, or serial port.
Settings made from script files are active only while the script file is running. When the
script finishes, settings revert back to the previous settings: the ones set from the front panel,
network, or communications port. Settings may be "locked-out" from certain sources. For
example, you may prevent the closed caption line to be changed from any source other than
the front panel. You enable or disable settings in a command acceptance table that is ac-
cessed from the front panel.
The DV2000 stores all current settings on its hard drive in a file called "settings.cfg". To
restore factory default settings, simply delete or rename this file.
Over Temperature Alarm
DV2000 contains an over temperature alarm that produces a continuous beeping if the
internal processor overheats. This could be caused by a dirty filter element, restricted air
flow, or fan failure. Operating DV2000 in an over-temperature condition will result in erratic
operation.
