EN | 47
To turn
OFF
an auxiliary function of a remote camera device, press
Aux OFF [OFF]
,
enter the number of the auxiliary you would like to deactivate and then press
[Enter]
.
With the AutoDome Series of cameras, auxiliary commands are used to activate/
deactivate certain operational features/functions. Refer to the AutoDome camera
manual for complete information on features supported by the model.
In the Allegiant Receiver/Driver Series, the first four auxiliaries correspond to relay
outputs. Option switches in the receiver/driver can configure these to operate as
either latching or momentary type functions. If configured for the latching type, the
auxiliary stays on once it is activated until it is turned
OFF
. If configured as momen-
tary, the auxiliary remains on only as long as the
[Enter]
key is pressed. Auxiliary
outputs 2 through 4 can also be configured as a contact closure, 24 VAC, or as line
voltage. Auxiliary number 5 controls the
DITHER
function, detailed below. Auxil-
iary number 6 corresponds to an internal receiver/driver
AUTOPANNING
feature,
previously enabled by an option switch inside the receiver/driver.
DITHER
is a legacy Allegiant receiver/driver feature designed to extend the life of
tube-based low-light level cameras. Its function was to prevent bright lights in the
scene from burning a spot on the camera imager. When this feature is active and the
pan/tilt is not moved for a period of about two minutes, the receiver/driver automat-
ically pans right for approximately 0.5 seconds. Two minutes later, a pan left occurs,
and the cycle continues until disabled. The feature is enabled by an option switch in
the receiver/driver, and is controlled by the auxiliary 5 function. To activate the
DITHER
function, turn [
ON
] auxiliary 5. To deactivate the feature, turn
OFF
auxil-
iary 5. When first enabled, the pan/tilt unit makes one short left/right cycle to indi-
cate that the
DITHER
function has been activated. Note that a camera in the
DITHER
mode will accumulate a viewing error if left unattended for a long period of
time, so occasionally a manual adjustment of the pan/tilt may be required.

Arm/Disarm Individual Alarms
Alarm commands control the system's automatic video switching capabilities, in
response to alarm signals.
When using IntuiKey keyboards, press [

, located on the main Alle-
giant menu screen, to enter a menu screen with these options. To arm an individual
alarm on the monitor currently controlled by the IntuiKey, press [

the alarm number to be armed via the numeric keypad, then press
[Enter]
. To dis-
arm an individual alarm when using the IntuiKey, press [

To arm/disarm an individual alarm when using an LTC 8555 Series keyboard, press
[
Alarm]
, enter the alarm number to be armed via the numeric keypad, then press
[ON]
to arm the alarm, or
[OFF]
to disarm it. The camera number activated by an
alarm, by default, is the same as the alarm number, although this relationship can be
changed via the optional Allegiant PC-based MCS package. When the alarm num-
ber does not match the camera number, it is important to specify the alarm number
when using this command. The monitor status display (if enabled) shows
C
A
(cam-
era/alarm armed) whenever an armed camera is selected.
