To program a specific camera select button for a switcher
camera number:
1. Press the front panel PGM button on the AD1202.
The PGM LED illuminates steadily, and the Channel Select
button 1 LED flashes repeatedly.
2. Press the desired AD1202 Channel Select button for the
specific camera input to be programmed.
The associated Channel Select LED flashes.
3. Press the desired camera select button on the switcher. The
switcher should indicate the selected camera. (Refer to the
appropriate switcher installation manual for the camera
selection procedures and indicators).
4. Confirm that the AD1202 Channel Select button LED and
the switcher selection indicate the desired choice. (Either
selection may be changed prior to the next step.)
Note: Do not program two different AD1202 buttons to the
same switcher camera number. If two buttons are
programmed for the same camera number the
AD1202 selects the lower numbered button for that
camera, and the other button is ignored.
5. Press the front panel SEL button. This accepts the choices
and programs the AD1202 external camera selection to
respond to the switcher camera selection.
The flashing Channel Select LED advances to the next
sequential Channel Select button to permit further
programming.
6. To program another channel select button repeat the above
steps from step 2.
Note: All programming of the select buttons will be held in
non-volatile memory and will not need to be re-
programmed upon a power failure.
Preset Scene Programming
Camera pan/tilt and lens units with preset capability can be
programmed to move automatically to preset scenes using
AD1640/1680 Series Receivers. A suitably equipped camera
site Receiver can store 72 preset scenes for subsequent recall.
The AD1202 can program and call any of the first four preset
scenes (1 - 4). Preset scenes are stored at the respective
camera Receiver, not in the AD1202.
Note: The front panel controls must be enabled for preset
programming (see Programming Blocking, page 5).
To program and store a preset scene:
1. Select the desired camera by pressing the corresponding
front panel Channel Select button.
2. Using the AD1202 front panel controls, adjust the camera
pan, tilt, zoom, iris, and focus to obtain the desired scene, as
viewed on the MON video output.
3. Press the front panel PRESET SET button.
The SET LED illuminates.
4. Enter the desired preset number (1 - 4) by pressing the
corresponding Channel Select button.
The Channel Select LED illuminates briefly to confirm the
selection, then both the SET and Channel Select LED’s turn
off, indicating that the preset scene is programmed.
If no Channel Select button is pressed within five seconds
after the SET button is pressed, the function is cancelled
and the SET LED turns off.
Programmed preset scenes 1 - 4 may be called by front panel
commands any time the associated camera is under control of
the AD1202 (see Calling a Preset Scene, page 9).
If Preset Scene 1 is programmed for a camera by the above
AD1202 procedure only, that preset is automatically called by
the AD1202 when an alarm is received on the Alarm Input
associated with that camera (see Alarm Response, page 10).
Note: All presets are held in non-volatile memory and will
not need to be reset upon a power failure.
Video Input Termination
The termination of each video input to the AD1202 may be
individually selected as terminated (75 ohms) or unterminated
(Hi-Z) via a rear panel DIP switch, labeled TERM (see Figure
6). Four separate switches are provided, labeled 1 to 4, one for
each corresponding video input channel. The factory default
setting of all inputs is Terminated, 75 ohms.
To change the termination of any video input, push the
associated slide switch (switch 1 for input channel 1, etc.) to
the appropriate position: up for terminated in 75 ohms, or
down for unterminated at Hi-Z.
