Setting Left and Right Scan Limits
Scan Limits allow you to set left and right boundaries for use with the Auto Scan, Frame
Scan, and Random Scan functions. If the scan limits are not set, the dome pans continuously
to the right when these functions are activated.
I M P O R T A N T
You must program the Left Scan Limit setting before programming the Right Scan Limit
setting. This procedure erases any previously programmed Right Scan Limit setting.
To program the Scan Limits:
1. Select the camera number assigned to the SpeedDome Ultra VII dome.
2. Use the pan/tilt control to position the dome's pointing direction to the Left Scan Limit.
3. Enter Set Preset 92 to save the setting.
4. Position the dome's pointing direction to Right Scan Limit.
5. Enter Set Preset 93 to save the setting.
Activating Auto Scan
Auto Scan allows the dome to continuously pan between the left and right scan limit settings.
When reaching the right scan limit, the direction is automatically reversed. If no scan limit
settings are programmed, the dome pans to the right continuously.
To activate the Auto Scan:
1. Select the camera number assigned to the dome.
2. Enter Go To Preset 99.
The Auto Scan runs until stopped by selecting the camera and entering Call Preset 96.
Note: Entering a pan/tilt or lens command also stops the scan.
