Continuum Headend Systems
Model 9800 Continuum NTSC Modulator System Chassis with four 9820 modulators, 9810 Controller and 9801 RIM (Rear Interface Module) Stereo
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.
