Introduction 
The Continuum
 Headend System product family provides 
users with a vertically-oriented, compact, full featured 
ensemble of headend functions.  The Model 9811 and 9814 
Controllers manage all activities between application modules 
in addition to supporting external monitoring and control. 
 
Description 
All Continuum configurations require one controller and its 
corresponding rear interface module per chassis. The Model 
9811 and 9814 Controller Modules support all chassis level 
functions required by any combination of application modules.  
A controller and its Model 9801 or 9802 Rear Interface 
Module (RIM) provide access to vital system connections 
such as AC or DC power input, all back-up connections, 
Transmission Network Control System (TNCS) connections, 
and alarm interfacing.  The controller also directs setup and 
control of all application modules. 
 
Model 9811/9814 Controller Modules are required to take advantage of the additional features and capabilities of 
the Continuum Series 9825 Modulators.  The Model 9811/9814 controllers are fully compatible with all versions of 
Continuum Application Modules and can be used in place of Model 9810/9813 Controller Modules if required. 
 
Note: Existing Model 9810/9813 Controller Modules need not be upgraded to Model 9811/9814 Controllers unless 
Continuum Series 9825 Modulator Modules are present in that respective chassis.  However, Model 9810/9813 
Controllers can be upgraded to Model 9811/9814 Controller compatibility if necessary.  Contact Scientific-Atlanta 
factory service for details.
