APPENDIX A - SATELLITE SYSTEMS

A satellite system configuration is usually used for a

large distributed system, or to obtain extremely large

matrix sizes configured more conventionally. Typically,

a single Main control site can be used to view/control

cameras located both locally and at various remote

satellite sites. Since many satellite sites can be linked to

a single Main control site, very large, distributed

systems can be achieved. If the satellite systems are

located at the same site as the Main system, the result

is a large conventional-type system. In a satellite

configuration, the Main control site can view/control

any camera in the entire system, but the remote

satellite sites can only view/control cameras associated

with their own site. Satellites may be configured to

operate either independently or, with no local

viewing/control capability.

The Main site must consist of any Allegiant Series

switcher (LTC 8100, LTC 8200, LTC 8300, LTC 8500,

LTC 8600, or LTC 8800). Satellite site switchers can be

any Allegiant model switcher. A LTC 8780 Series Data

Converter is required at each satellite site, to perform

address decoding and data conversion for the

switching system. If the satellite site contains

pan/tilt/zoom cameras, a LTC 8569 Code Merger is

also required at the satellite site. All products are

standard models, and the only required option is to

use either the Master Control Software for Windows

LTC 8059/00 or the LTC 8850/00 GUI software

package for initial programming of each Allegiant

system.

Each satellite site must have an Allegiant control data

line from the code distribution unit at the Main site.

This data line carries all pan/tilt/zoom control

commands, in addition to the switching commands

generated by the Main site switcher. The control data

line should be connected to a LTC 8780 Series Data

Converter to provide address decoding functions for

the satellite site. If operators at the satellite site are

permitted to control pan/tilt/zoom-equipped cameras,

a LTC 8569 Series Code Merger must be installed at

the satellite site. The Code Merger combines code

generated by the main site and the satellite site, so

both sites have control over pan/tilt/zoom-equipped

cameras located at the satellite site. The LTC 8780

Series unit can then be connected to one of the data

outputs of the LTC 8569 Series unit.

One or more monitor outputs from each satellite

system are used as trunk lines to link the remote sites

to the Main site. The number of trunk lines from a

satellite site determines the maximum number of

cameras from that site that may be viewed

simultaneously at the Main site. A satellite switcher

can provide only as many trunk lines as it has

monitor outputs.

Sufficient monitor outputs used as trunk lines must be

included in remote satellite switcher sites. The Main

site switcher must include sufficient camera inputs for

local cameras plus trunk lines. The maximum physical

number of camera inputs or monitor outputs used as

trunk lines cannot exceed the capacity of the system.

A single Main site switcher can control multiple

satellite sites up to its video input limit. If full matrix

switching is required at the Main site, the number of

trunk lines from each satellite site must equal the

number of monitors connected to the Main site

switcher. Multiple independently controlled Main site

systems can be combined to provide large numbers of

monitor outputs at the Main site. System capacities are
