A satellite system is a network of two or more 
MegaPower 3200 video-matrix CCTV systems linked by 
video and data communications. You can link up to 30 
individual MegaPower 3200 video-matrix CCTV 
systems into a satellite network. 
Satellite systems are often used where multiple systems 
are needed in separate buildings or rooms, such as 
large multi-building corporate complexes, manufacturing 
facilities, college campuses, hospitals, and casinos. 
Each satellite site communicates and shares video 
according to how you program it. You can enable 
operators at any one site to access the cameras and 
monitors at any other site. You can also restrict access 
to sites, as well as to certain cameras within certain 
sites. 
Satellite sites are programmed as either local or remote 
sites. 
• A 

local site refers to features that are accessible 

within a single site by the keyboard attached to that 
site’s MegaPower CPU. 

• A 

remote site refers to features of other MegaPower 

CPU sites in a satellite network that are accessible 
from the local system. 

Depending on the individual site connections 
(unidirectional or bidirectional), each site may be a 
source site, a receiving site, or both. 

For illustrations of unidirectional and bidirectional 
connections between sites, refer to the following: 
•  Typical Satellite System Connections – Two 

Sites, Unidirectional on page 81. 

•  Typical Satellite System Connections – Two 

Sites, Bidirectional on page 82. 

These sites are further defined as follows: 
•  Source Site – a satellite site that provides video 

trunk outputs to other sites. 

•  Receiving Site – a satellite site that receives video 

trunk inputs from other sites. 

•  Source and Receiving – a satellite site that both 

provides video trunk outputs to other sites and 
receives video trunk inputs from other sites 

Satellite system operations require specific setup 
procedures at each site in the satellite network before 
any remote functions can be performed. 

At every site in a satellite network you can enable User 
IDs, create a site number, and perform other 
programming functions to enable or disable sharing. 

The following local setup procedures are required for 
satellite (remote) operations. 
•  Verify Satellite Site Connections – Before starting 

system setup, verify the RS-232 communications 
links for control commands between sites and video 
trunk lines for video transmission between sites. For 
installation and connection procedures, refer to the 
MegaPower CPU Installation Guide, 8200-0421-01. 

•  Identify the local Site Number – Assign each site 

in a satellite network a unique site number. The site 
number is required for addressing purposes when 
commands and data are transmitted. Site numbers 
for the MegaPower CPU system range from 1 to 30. 

•  Identify the Local RS-232 Data Communications 

Link to Other Sites – At every site, define all 
RS-232 port data interfaces from the local site to 
each remote site. This is accomplished through the 
Port Communications function in the setup software. 

•  Identify the Local Video Trunk Inputs – At a 

receiving site, define all video trunk inputs to the 
local site from each remote site. In addition, program 
a remote site title for each video trunk input. 

Note: This title is displayed on the monitor when that 
site is called from a keyboard. 

If the MegaPower CPU system is equipped with 
Video Loss Detector modules, set each video trunk 
input loss detection to OFF. 

•  Set Local Access Restrictions – Access 

restrictions must be placed on specific resources at 
the local site to prevent interference with satellite 
operations. 
−  At the source site, set user access to the video 

trunk monitor outputs to “N” (access denied) for all 
local keyboards. 

−  At a receiving site, operators not requiring access 

to a remote site can be denied access to the trunk 
lines having camera access partitioning. The 
system administrator can set the camera access 
to “N” (access denied) for those operators. 

−  At a receiving site, set any desired restrictions for 

individual local keyboard access to individual 
remote sites. 

−  At each site, set any desired optional restrictions 

for individual local keyboard, monitor, and camera 
access. 

•  Record Local Satellite Site Connections – Use 

the Satellite Site Connections table on page 80 to 
record all links between the local site and all remote 
sites that are connected to it.
