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 video trunk lines to link the remote sites to the Main site. The number of trunk lines from a sat- ellite site determines the maximum number of cameras from that site that may be viewed simultaneously at the Main site. A satellite switcher model must be selected so that it provides the desired number of local monitor outputs plus the number of monitor outputs that will be used as trunk lines.

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. Multi- ple independently controlled Main site systems can be combined to provide large numbers of monitor outputs at the Main site. System capacities are listed below:

System Type	Max. Camera	Max. Monitor	Max. No. of
	Inputs	Outputs	Satellite Sites
LTC 8100 Series	8	2	8
LTC 8200 Series	16	5	16
LTC 8300 Series	32	6	32
LTC 8500 Series	64	8	64
LTC 8600 Series	128	16	128
LTC 8800 Series	256	64	256
LTC 8900 Series	4096	512	256

Since Main site Allegiant Series switchers support access to a large quantity of remote satellite cameras, they provide additional logical camera numbers for identi- fying the location of the satellite camera inputs in the system. These logical camera numbers can also include titles which would appear on the Main site's monitors for any remote cameras. Since each camera (anywhere in the system) must have a unique camera number, logical camera numbers together with physical camera inputs make up the total system camera capacity. Thus, there is a trade-off between the total number of Main site cameras and the number of inputs used as trunk lines.

The more inputs used as trunk lines, the fewer there are for use as direct camera inputs.
