SETUP
Factory Reset
The AD1202 can be reset to factory default settings which are
as follows:
• resets the programmed AD1202 camera inputs (see
Camera Programming) to cameras 1 through 4,
respectively,
• cancels front panel programming block, if enabled (see
Front Panel Controls, page 5), and
• disables all presets
To reset the AD1202 to factory defaults:
1. Remove power from the AD1202.
2. Press and hold the IRIS OPEN and FOCUS NEAR buttons
on the front panel while applying power to the unit.
Camera Selection
The AD1202 selects a camera either manually, using the front
panel controls, or externally, as a switcher controller.
Camera selection is controlled by pin 21 (External Unit) on the
EXTERNAL connector (see CONNECTIONS, page 3).
Coax Controller (Stand-Alone)
To enable manual (front panel) camera selection, leave pin
21 on the EXTERNAL connector open.
In this mode, the front panel Channel Select buttons select a
camera input for control (see Manual Camera Selection,
page 8).
Control Follower (Used in External Switcher)
To enable External camera selection (from a compatible
AD switcher), connect pin 21 to Ground (pin 16, 22, or 24)
on the EXTERNAL connector.
When set for this mode, camera selection is provided by the
switcher EXTERNAL connection (BIN IN pins) only; the
front panel Channel Select buttons cannot select a camera.
External camera selection can be programmed for any four
camera numbers selected by a compatible AD switcher (see
Camera Programming).
Camera Programming
When External camera selection is enabled, AD1202 camera
selection can be programmed to respond to (follow) any four
camera numbers selected by a compatible AD switcher.
The AD1202 is factory set for operation with input number 1
set to follow switcher camera 1, input 2 for camera 2, input 3
for camera 3, and input 4 for camera 4. Each AD1202 input
can be programmed to follow any of 16 camera numbers.
Note: To program the AD1202 camera inputs, the camera
address binary output from the switcher must be
connected to the AD1202 BIN IN pins (see page 3)
and pin 22 on the EXTERNAL connector (located on
the rear panel) must be grounded..
The front panel controls must be enabled for camera
programming (see Programming Blocking, page 5).
To program all four camera select buttons 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 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.)
3. 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.)
4. 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.
5. To program the remaining camera select buttons repeat
steps 2 through 4. After the fourth camera select button has
been programmed the first LED above the first camera
select button will again begin to flash. If all the camera
select buttons have been properly programmed, simply exit
the programming mode.
6. To exit programming mode, press the PGM button. The
PGM LED turns off and the Channel Select LED’s indicate
the channel selected prior to the start of programming.
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.
