Input Expansion

Input expansion requires output combiners and output gain increase.

Full Chassis Input Expansion

In this arrangement all outputs are combined and must therefore be

boosted. For example, in the system shown in

Figure 63

, Output 1 of

Frame 0 would be combined with Output 1 of Frame 1, Output 2 of

Frame 0 would be combined with Output 2 of Frame 1, etc.

Figure 63.

The necessary gain increase is accomplished by
• Closing the rear-panel Input Expand DIP switch (for the location of

this switch, see

page 98

[128 x 128];

page 100

[256 x 256]; or

page 102

[512 x 512]), and

• Setting the output board jumpers (or DIP switches) to the “Expand

Enable” position (as shown on

page 128

and

page 129

).
