36 Pelco Manual C1487M-D (7/99)
To change the line synchronization settings:
1. Program preset 95 (28 if in 32-preset mode; refer to the
Preset Functions
section) to
access the main menu (refer to the
Main Menu Access
section). The main menu will
appear.
2. If the cursor (>) is not beside Line Sync, move the joystick up or down to position the
cursor beside Line Sync.
3. Press the Iris Open button on your keyboard. Another menu will appear with the Line
Sync and Line Sync Phase selections.
4. Move the joystick up or down to position the cursor beside one of the choices.
LINE SYNC - The cursor moves to one of two choices: On or Off. Move the joystick up or
down to toggle between them.
Press the Iris Open button to select the choice. If you changed to Off, the camera may
reset itself as it adjusts to the new synchronization. If the camera resets, it will only affect
the line synchronization. It will
not
change any other camera parameters, such as auto
focus or auto iris.
Press the Iris Close button if you do not want to change the setting.
LINE SYNC PHASE - The cursor moves to a numeric value. Move the joystick up or
down to change the value.
Press the Iris Open button to select the choice. The value represents the phase angle in
tenths of a degree between 0 degrees and 359 degrees for Spectra II™ and 0 to 350
degrees for Spectra Lite™. For example, 900 is 90 degrees, 1200 is 120 degrees, and
2400 is 240 degrees. Press the Iris Open button on your keyboard to select your choice.
The Line Sync setting will change to On. The camera may reset or the picture on your
monitor may wiggle when you change the phase angle. If the camera resets, it will only
affect the line synchronization. It will
not
change any other camera parameters, such as
auto focus or auto iris.
Press the Iris Close button if you do not want to change the setting.
POWER-UP MODE
This feature lets the dome resume a desired condition following power-up. The menu
includes the following choices. (An asterisk denotes items that apply to the
Spectra II™ only.)
• Default - On power-up, the dome goes through a configuration cycle and stops at zero
reference, showing “Configuration Done,” address, and mode settings on the screen.
• Park - The dome moves to preset 1 when the power-up sequence finishes. The only
text on the screen is the preset label (if any is programmed).
• Scan Auto - The dome initiates scan mode when the power-up sequence finishes.
Again, there is no text.
• Scan Frame - The dome initiates a frame scan when the power-up sequence
finishes.
• Scan Rand - The dome initiates a random scan when the power-up sequence
finishes.
• Full Pat* - The dome initiates its programmed pattern when the power-up sequence
finishes. The length can be set to 1.5, 3, or 6 minutes.
• Half Pat 1* - The dome initiates the first half-pattern when the power-up sequence
finishes. The length can be set to .75, 1.5, or 3 minutes.
• Half Pat 2* - The dome initiates the second half-pattern when the power-up
sequence finishes. The length can be set to .75, 1.5, or 3 minutes.
The default setting is Default.
