Pelco C1498M-B PAN and Tilt Functions, Auto Flip, Scan Speed, Zoom, Preset Functions

PAN AND TILT FUNCTIONS

Use your controller’s joystick to control pan and tilt operation.

•Fixed-Speed Controllers – Pan and tilt operation is at a fixed speed; the controller determines the speed.

•Variable-Speed Controllers – Depending on the joystick’s position, standard pan operation ranges from 0.5 to 80 degrees per second (dps); standard tilt operation ranges from 0.5 to 40 dps. When performing preset operations, pan speed is 250 dps; tilt speed is 200 dps. In turbo mode, pan speed is 150 dps, while turbo mode does not affect tilt speed.

AUTO FLIP

When the camera tilts down and just beyond vertical, the dome rotates 180 degrees. When the dome rotates (flips), the camera starts moving upward while you continue holding the joystick in the down position. Once you release the joystick after the dome rotates, joystick control returns to normal operation. Auto-flip is useful for following someone who passes directly beneath the camera. You can disable this feature in the auto flip programming menu.

SCAN SPEED

Scan speed is adjustable from 1 to 40 degrees per second through the programming menu.

ZOOM

The Spectra Lite™ dome can magnify an object up to 16 times (16X of optical zoom).

Zoom Telephoto – Press and hold down the Zoom Tele button or turn the joystick clockwise until you have the picture you want.

Zoom Wide – Press the Zoom Wide button or turn the joystick counterclockwise to increase the field of view.

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

94 becomes 27

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 Lite™ dome can go to 32 preset locations, each with a 20-character label. Presets are numbered 1-32. Refer to your control system documentation for programming presets.

When doing a preset operation, the amount of error in moving to the pan and tilt positions is 1/2 degree. You may get erratic operation if you command the dome to go to an undefined preset.

Presets 33 and 34 are fixed commands (you cannot program them). Preset 33 is the “flip” command, which pans the dome drive 180 degrees from its current position. Preset 34 is the “pan zero” command, which directs the dome drive to the factory-determined zero reference point. The following presets are reserved for special functions.

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.

RANDOM, FRAME, AND AUTO SCANNING

Program preset 97 (30) to start random scanning. Program preset 98 (31) to activate frame scanning (three seconds of scanning followed by a three-second pause). Program preset 99 (32) to start auto (continuous) scanning.
