Calling a Preset Camera Scene
A suitably equipped AD Receiver can store a maximum of 72
preset scenes. The AD1202 can call any of the first four preset
scenes using the front panel PRESET buttons. See Preset
Scene Programming, page 7, to program preset scenes.
To call a preset scene:
1. Select the desired camera (manual or external selection).
2. Press the front panel PRESET CALL button. The CALL
LED illuminates.
3. Press the Channel Select button corresponding to the
desired preset scene number (1 - 4). The Call LED turns
off.
If no Channel Select button is pressed within five seconds,
the function is cancelled.
Note: If a preset is called and no preset scene has been
programmed for that preset number, the camera
movement may be unexpected.
Activating an Auxiliary
The AD1202 can activate any of four auxiliary functions at a
camera site (lights, gates, etc.) using the front panel AUX
ON/OFF buttons. These buttons control either momentary or
latching auxiliary actions. The number and type of auxiliary
functions at a camera site depends on the options installed in
the camera Receiver at the site.
To activate an auxiliary:
1. Select the desired camera (manual or external selection).
2. Press the AUX ON button on the front panel. The AUX
ON LED illuminates.
3. Press and hold the Channel Select button corresponding to
the desired auxiliary number (1 - 4).
4. Release the button when the desired action is achieved. The
AUX ON LED turns off.
• If the auxiliary is a momentary type, the action stops.
• If the auxiliary is a latching type, the action continues
until the auxiliary is deactivated, as described below.
To deactivate a latching auxiliary function:
1. Select the desired camera (manual or external selection).
2. Press the AUX OFF button on the front panel. The AUX
OFF LED illuminates.
3. Press the Channel Select button corresponding to the
desired auxiliary number (1 - 4). The AUX LED turns off.
Alarm Response
There are four alarm inputs on the rear panel EXTERNAL
connector (see page 3). Each alarm input corresponds to one
of the four video input BNC’s on the rear panel. The alarm
inputs can be connected to any device that produces a contact
closure on alarm.
ALARM RECEIPT
The AD1202 detects and responds to external alarms when
there is a contact closure at any alarm input.
1. The camera corresponding to the alarm is selected by the
AD1202. In External camera selection mode, this
selection follows the switcher alarm response selection.
2. If preset scene number 1 has been programmed for this
camera by the AD1202 (see page 7), this preset is called.
If preset 1 was not programmed the preset will not be
called.
3. A pulse is output on the Alarm Out pin (see page 3).
The alarm pulse is held active until the alarm input
clears, with a minimum duration of five seconds.
4. If the AD1202 is in camera selection mode:
The Channel Select button LED corresponding to the
alarm input flashes until the alarm is acknowledged
(see Alarm Acknowledge, below).
If the AD1202 is in camera selection mode:
All active alarms are indicated by the external switcher
connected to the AD1202.
ALARM ACKNOWLEDGE
If the AD1202 is in camera selection mode:
• Press the AD1202 Channel Select button associated with
the flashing LED to acknowledge the alarm. The LED
stops flashing and remains illuminated until a different
channel is selected.
If the AD1202 is in camera selection mode:
• Acknowledge the alarm at the external switcher.
(Refer to the appropriate switcher installation manual for
alarm acknowledge procedures.)
In either mode, the alarm output pulse is reset only after the
alarm input is cleared (contact is reset), with a minimum
pulse duration of five seconds.
AD1202 OPERATION
Note
For proper alarm response when used as a control follower
camera selection mode, all alarm inputs must be connected
in parallel with both the external switcher and the AD1202.
