24 Pelco Manual C1487M-D (7/99)
POWER-UP DISPLAY
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.
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.
