PRESET FUNCTIONS

NOTE: For American Dynamics controllers with only 32 presets, set switch SW1-7 on the dome drive in the ON position. When SW1-7 is ON, preset

99 becomes 32

98 becomes 31

97 becomes 30

96 becomes 29

95 becomes 28

93 becomes 26

92 becomes 25

91 becomes 24

90 becomes 23

If the limit stops are turned off (refer to the Limit Stops section), presets 23-26 can be used as regular presets.

The Spectra II™ dome is capable of going to 64 preset locations, each with a 20-character label. The presets are numbered 1-32 and 35-66. The Spectra Lite™ dome can go to 32 presets. The presets are numbered 1-32.

Refer to the documentation for your control system for programming presets.

When a preset operation is performed, the amount of error in moving to the pan and tilt position is 1/2 degree. If you command the dome to go to an undefined preset, erratic operation may result.

Presets 33 and 34 are fixed commands, meaning that you cannot program them. Preset 33 is the “flip” command, which will pan the dome drive 180 degrees from the position it is at. Preset 34 is the “pan zero” command, which will direct the dome drive to the factory- determined zero reference point.

The following presets are reserved for special functions. (An asterisk denotes

presets that apply to Spectra II only.)

In the following sections, sometimes a number in parentheses follows a preset. This second number is for 32-preset mode (conversion that lets Pelco’s presets work with American Dynamics controllers). If you are using an American Dynamics controller, use the number in parentheses.
