Tektronix 2200 Manual Do Utilizador

Model 2200 Series electronic circuitry is contained on circuit modules in the 
switcher frame, effects frame, and control panel. 

In this manual and in other related documents, the circuit modules will be 
referred to by the names and assembly numbers printed on them.

 

The control panel is the operator interface for the Model 2200 system and 
provides all operator controls for the switcher and effects systems.

Through the control panel, the operator performs all actions via 
mechanical buttons and controls, or through software controlled menus 
and soft button adjustments. The control panel provides the data links to 
both Frames.

 

 

 

all of the signal processing modules along with some control processor 
modules.

 The Head-of-State (HOS) processor and all M/E processors reside on two 
Control Processor modules in Bay A (front bay) of the frame. Control 
Processor 1 contains the HOS processor which supervises the state of the 
switcher, handles communication with the control panel and controls the 
video hardware. The M/E 1 processor also resides on this module.

The Control Processor 2 contains the circuitry for communication with the 
editor, tally expansion and other remote control. The M/E 2 processor is on 
this module.

Since each M/E has its own processor, failure of the HOS processor does 
not shut down the entire switcher. Individual M/Es can continue to 
operate independently, although in a degraded capacity (cuts, mixes and 
fade- to-black continue to operate).

The control panel communicates with the switcher frame over two RS-422 
data links, one per M/E. Both of the links is contained within a single cable 
that may be up to 1000 feet long.
