Automatic Back-up 
The controller initiates and maintains command over back-up signal routing in the event of an application module 
malfunction.  Continuous communication between the controller module and its application modules maintains up-
to-the-second system status.  Extensive internal diagnostics within application modules, in coordination with 
controller communication, speeds signal re-routing to a designated back-up module. 
 
Dual Powering Options 
Available powering options include AC powering with DC back-up (Model 9811), and DC powering with DC back-up 
(Model 9814).  For international applications, AC powering is universal (90 V AC to 264 V AC, 47 Hz to 63 Hz).  DC 
input range is -42 V DC to -60 V DC SELV.  Both controllers support full chassis powering of any mix of application 
modules. 
 
Alarm Outputs 
"Dry" contact closures are provided on the rear interface module for alarm connection.  Users can select either 
Normally Open (NO) or Normally Closed (NC) contact types for alarm outputs. 
 
SMC (Status Monitoring and Control) 
The SMC bus allows complete remote control operation of all application module functions and chassis level 
functions managed by the controller module.  Interface is via two RJ-14 style jacks on the controller that are 
designed for loop-through cabling.  This feature allows daisy-chaining of multiple SMC equipped units. 
 
Local Control Port 
The controller provides front panel access for local control of all functions.  The local control port is equivalent to, 
but electrically isolated from, the SMC interface.  SMC activity has priority and is not affected by use of the local 
control port. 
 
Back-up Bus Access 
This feature allows an external module outside the Continuum Headend System chassis to back-up a faulty 
application module inside the chassis.  This feature is useful when back-up groups larger than eight application 
modules are desired.  Back-up busses are available for audio (L, R, SAP, subcarrier) and baseband video.  
 
Model 9825M and 9825S Modulators Memory Expansion 
The new Continuum Modulators (Models 9825M and 9825S) contain added feature sets that require additional 
memory in the controller module for proper operation.  The Model 9811 and 9814 Controller Modules contain this 
necessary memory expansion.  Models 9810 and 9813 Controller Modules may be upgraded to Model 9811/9814 
Controller capability.
