Tektronix Camcorder 2200 User Manual

2-5

All buttons in the Source Select region have three levels of 
illumination:

■

OFF indicates not selected;

■

DIM or “low tally” indicates selected, but not on-air;

■

BRIGHT or “high tally” indicates selected and on-air.

Only one button in each row is illuminated at any time.

The Source Select Buttons are used to select which of the 
inputs into the switcher will be used in the switcher. 
Each row of primary source selection buttons consists of 
16 buttons. Each can have a designator under a clear 
lens cap. 

Each input, including internally generated signals such as black 
and background, can be mapped to any vertical column of 
crosspoint buttons. Thus, each column of buttons may be 
visualized as an input bus of video or key crosspoints. Each input 
can be treated as either a video signal or a key signal, as defined 
in the Configuration menu. 

The input signals on each input column can be placed on any 
output bus (horizontal row) by pressing the crosspoint button at 
the intersection of the column and row. Any video/key input may 
be selected on any number of output buses; however each output 
bus can have only one output signal selected on it at one time. 

The

 button located at the right end of each primary source 

selection row is used to access inputs 17 through 32. To select a 
shifted input, hold

 down (button lamp comes on) and press 

a crosspoint button on that bus. The

 button lamp then 

remains lit to show that the selection is a shifted selection. The 
Shift mode will turn off when an unshifted selection is made on 
that bus.
