LTC 8850 | Instruction Manual | Allegiant Server

Use Default Camera

When this option is checked, whenever a user logs

onto an Allegiant keyboard, the connected monitor

will switch to the default camera for that user. See the

User Table SECTION. Otherwise, this automatic

switching will not take place.

Keyboards 1-8 on Expander

When this option is not checked, the eight keyboard

ports on the back of the main Allegiant bay are active.

When this option is checked, the system will expect

keyboards 1 through 8 to be provided by the keyboard

port expander accessory unit.

Display Leading Zeros

When this option is checked, leading zeros for camera

numbers will be displayed on the system monitors.

Otherwise, only significant digits are displayed.

Use Four Digits on Camera Overlay Display

Normally, camera numbers, displayed on system

monitors, are limited to three digits. When this option

is checked, four digits will be displayed.

Display Camera Control Status on Monitors

If this option is checked, a monitor will display a

double ended arrow <-> if the camera it’s receiving

video from has pan/tilt/zoom capabilities. A camera is

assumed to have these capabilities if its Controllable

checkbox is enabled in the Camera Table. These

options can also be set using Keyboard User Function

34 and 35.

Monitor n1-n2 Activations to Biphase Port

The system normally sends crosspoint information to

the biphase port for use by certain Allegiant accessory

units. If this information is not needed for the

indicated monitors, it may be disabled by unchecking

the enabled box. In large systems, this might improve

overall system performance slightly. The numbers, n1

n2, depend on the model number.

IMPORTANT: If switcher-follower accessory units are

being used in the system, these boxes must be

checked. These functions can also be set using

Keyboard User Function 36.

Use Logical Camera ID in Crosspoints

The system normally sends crosspoint information to

the biphase port for use by certain Allegiant accessory

units using physical camera numbers. If logical camera

numbers are required, check this option.

Limited Printing

When the box is checked, alarm messages that are

logged on the printer will be verbosely detailed. If the

box is not checked, then less detail will be printed with

a decrease in the number of lines logged to the printer.

Variable Speed Receiver/Driver

The type of control code the Allegiant system

generates depends on two settings in the CPU:

whether the variable speed operation is enabled with a

checkbox in the Parameter Options Table or by the

User Function 22, and whether the system is using the

6 poll byte keyboard communication mode set via

CPU dip switch 7.

If the variable speed operation is not checked, variable

speed keyboards, such as the IntuiKey Series and

LTC 8555, will operate all devices at a fixed speed. If

the variable speed operation is checked, variable speed

keyboards will control the AutoDome Series cameras

at a variable speed. The LTC 8560 Series and

LTC 8561 Series receiver/drivers can only operate at a

fixed speed regardless of the type of control code

being generated.

Enable Video Loss Display on Monitors

If this option is checked, a monitor will display a

message when it experiences video loss. This feature

will only work if your Allegiant system has output

cards supplied after September 1996 (not applicable in

LTC 8500 systems).

Alarm Set #n Activations to Biphase Port

This option enables special information for alarm set

#n to be sent out of the biphase port. This data can be

used by certain Allegiant accessory units to distinguish

between normal video and alarm video. These

functions can also be set using Keyboard User

Function 36.

IMPORTANT: If switcher-follower accessory units are

being used in the system for alarm-related functions,

the appropriate boxes must be checked.
