LTC 8100, LTC 8200, LTC 8300 Series | Instruction Manual | Keyboard Operation

12.4.6 Recalling a Camera Pre-position Scene

Select the camera to be activated. Press Shot, enter a

previously stored camera position number via the

numeric keypad, then press [Enter]. The camera

automatically returns to the previously stored position. If

a second pre-position is called prior to the completion of

the first, the camera will move directly to the second shot.

If the AutoDome Series camera is being used, certain

pre-position commands are also used to activate

operational features/functions. Refer to the AutoDome

operation manual for complete information.

12.4.7 Activate/Deactivate Auxiliary Function

When using IntuiKey keyboards, press Camera Control,

on the main Allegiant menu screen, to enter a menu

containing this option. To turn on an auxiliary function of

a remote camera device, press Aux ON [ON], enter the

number of the auxiliary you wish to activate, then press

[Enter]. Holding the [Enter] key down causes the

auxiliary function to be sent repeatedly. This capability is

useful when the auxiliary is activating a housing window

washer function, or a temporary light source.

To turn off an auxiliary function of a remote camera

device, press Aux OFF [OFF], enter the number of

the auxiliary you wish to deactivate, 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

4 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 will stay

on once activated, until turned off. If configured as

momentary, the auxiliary remains on only as long as the

[Enter] key is depressed. 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. Auxiliary 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 2 minutes, the receiver/driver

automatically pans right for approximately 0.5 seconds.

Tw o 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 auxiliary 5. When first enabled, the pan/tilt

unit makes one short left/right cycle to indicate 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.

12.5 Alarm Commands

12.5.1 Arm/Disarm Individual Alarms

Alarm commands control the system's automatic video

switching capabilities, in response to alarm signals.

When using IntuiKey keyboards, press Alarm

Control, located on the main Allegiant menu screen,

to enter a menu screen with these options. To arm an

individual alarm on the monitor currently controlled

by the IntuiKey, press Arm Alarm, enter alarm

number to be armed via the numeric keypad, and

press [Enter]. To disarm an individual alarm when

using the IntuiKey, press Disarm Alarm, enter the

alarm number to be disarmed via the numeric keypad,

and press [Enter].

To arm/disarm an individual alarm when using

LTC 8555 Series keyboards, press Alarm, enter in the

alarm number to be armed via the numeric keypad, and

press [ON] to arm the alarm, or [OFF] to disarm it.

Using default settings, the camera activated by an alarm is

normally the same as the alarm number, although this

relationship can be changed via the optional Allegiant

PC-based MCS package. When the alarm number 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

(camera/alarm armed) whenever an armed camera is

selected.
