Pelco C1487M-D POWER-UP Display, PAN and Tilt Functions, Auto Flip, Scan Speed, Protocol C

POWER-UP DISPLAY

NOTE: The dome will stop operating if the voltage at the dome drops below 18 VAC. It will turn back on and go through its start-up rou- tine when the voltage ex- ceeds 18 VAC.

When the Spectra II™ dome or Spectra Lite™ dome is powered up or reset, the selected protocol, revision number, and other information is displayed on the monitor. For example, the screen might show the following information:

PELCO SPECT II 4.0

CONFIGURE DONE

Protocol C

The information remains on the monitor until the dome is moved. The information displayed depends on the selected protocol and the choice made on the menu for selectable power- up mode, a feature that lets the dome resume a desired condition upon power-up. As a default, the dome goes to a random position. (Refer to the Power-Up Mode section).

The control system protocol (C, D, or P) appears. C is for Pelco’s Coaxitron® control systems. D-type control is RS-422 that is compatible with Pelco’s CM6700, MPT9500 and CM8500 controllers or with American Dynamics control systems using the AD2083 Translator. P-type control is RS-422 that is compatible with Pelco’s CM6700 and CM9750/ CM9760 control systems.

For the D and P protocols, the device address, baud rate, parity (N), number of data bits (8), and number of stop bits (1) appears. For the D protocol, if the mode for 32 presets is selected (SW1-7 is ON), “32 presets” appears.

If the CM9500 mode is selected (SW1-8 is ON), “CM9500 mode” appears.

PAN AND TILT FUNCTIONS

Use the joystick on your controller to control pan and tilt functions.

Pan and tilt operation is at a fixed speed with fixed-speed controllers. The speed is determined by the controller.

Standard pan operation with variable-speed controllers will range from 0.5 to 80 degrees per second, depending on the position of the joystick. In the turbo mode, pan speed will be 150 degrees per second. When performing preset operations, pan speed will be 250 degrees per second.

Standard tilt operation with variable-speed controllers will range from 0.5 to 40 degrees per second, depending on the position of the joystick. When performing preset operations, tilt speed will be 200 degrees per second. Turbo mode does not affect the tilt speed.

(Spectra II™ Only) If the proportional pan mode is enabled (refer to the Proportional Pan section), the pan (and tilt) speed will depend on the amount of zoom. At telephoto zoom settings, the pan (and tilt) speeds will be slower for a given amount of joystick deflection than at wide zoom settings. This keeps the image from moving too fast on the monitor when there is a large amount of zoom. This slowing does not happen when going to a preset, but does occur in turbo mode when high zoom is selected.

AUTO FLIP

When the camera tilts downward and goes just beyond the vertical position, the dome rotates 180 degrees. When the dome rotates (flips), the camera starts moving upward as long as you continue to hold the joystick in the down position. Once you let go of the joystick after the dome rotates, joystick control returns to normal operation. The auto-flip feature is useful for following a person who passes directly beneath the camera.

You can disable this feature in the auto flip programming menu. Refer to Auto Flip in the Programming the Spectra II™ and Spectra Lite™ section.

SCAN SPEED

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