Using the AD2089 in Operate Mode
16 AD2089 Operator’s Manual
The AD2089 joystick controls the panning and tilting of cameras connected to the switching
system. As the joystick is moved to the left or right, and is moved towards or away from the
operator, the camera will pan and/or tilt accordingly.
For cameras with variable speed pan/tilt capability, camera movement speed is proportional to the
positioning of the joystick. The further from the stationary center position the joystick travels, the
faster the camera will move. There are eight independent speed levels for the up, down, left, and
right directions.
Center the joystick when the camera has been positioned appropriately.
Locking and Unlocking a Camera
After calling a pan/tilt camera to view and control on a system monitor, an operator can prevent
other operators from controlling the movements of the called camera. This is referred to as
“locking” the camera.
To lock a camera:
1 Enter the camera identification number on the numeric keypad (the number appears in the
ENTER display).
2 Press [2], [F1]. This locks the called camera.
To unlock a camera:

ENTER display).
2 Press [1], [F1]. This unlocks the called camera.
Controlling Camera Zoom
Zoom refers to the apparent action of moving closer to or farther away from an object, as seen
through the camera lens. Zoom functions are controlled by twisting the control knob of the three-
vector joystick. Twisting to the right (“TELE”) enables the camera to zoom in. Twisting to the left
(“WIDE”) enables the camera to zoom out.
Controlling Camera Focus
Focus refers to the action of adjusting the clarity of the camera image displayed on the monitor. To
focus the camera on a distant object, press the FAR key. To focus on a closer object, press the
NEAR key.
Controlling the Camera Iris
Normally, the brightness of a picture is controlled by the camera's auto gain and the auto/manual
iris functions. However, there may be times when you would like the picture on the monitor to
appear darker or lighter. To brighten the picture, press the iris OPEN key. To darken the picture,
press the iris CLOSE key.
