Pan and Tilt
The joystick on the HEGS5000/5001 controller is used to control the pan and tilt functions
of the ACUIX. The maximum pan speed is selectable between 120°, 240°, or 480° per
second. The maximum tilt speed is one-half the maximum pan speed. If the maximum pan
speed is set to 240° per second, the maximum tilt speed is set to 120° per second. The pan
and tilt speeds are set in the on-screen setup menus under Control Options.
Note If the pan and/or tilt functions of the ACUIX are reversed through the
on-screen setup menus, joystick up performs tilt down, joystick down
performs tilt up, joystick left performs pan right and joystick right performs
pan left.
Note The HEGS5000/HEGS5001 controller will not function properly if the polarity
of the 2-wire RS485 lines is reversed.
Lens Control
The camera/lens package in the ACUIX provides automatic exposure control. The lens iris,
camera video gain, and camera shutter speed adjust automatically to the brightness of the
scene (unless manual exposure, or iris, is selected at the controller).
Under normal conditions the camera shutter is set to 1/60s for NTSC and the video gain is
set to 1 (0dB). As the light level varies in this normal area the lens iris is opened and closed
to compensate for the variations in the light level.
If the light level increases beyond the level that can be compensated for by closing the lens
iris the camera will begin to decrease the time that the electronic shutter is opened down to
a minimum of 1/10000s.
If the light level decreases when the camera is operating at a shutter speed of less than
normal (see above) the shutter time will increase until it reaches the normal time and if the
light level decreases beyond the level that can be compensated for by opening the lens iris
the camera will begin increasing its video gain.
