Duplication and Expansion
Full Frame Output Expansion
The Full Frame Output expansion configuration, all inputs are split and
must therefore be boosted. For example, in the system shown in
Figure 107 ,
Input 1would be split (duplicated) and sent to both frames, etc.
Figure 107.
Note Use the PE33016 Port expander for HD operations and the PE2x2-3G Port
expander for 3G operations.
The necessary gain increase is accomplished by
1. Closing the rear-panel Input Expand DIP switch.
For the location of this switch, see:
• Figure 63 on page 136 [128 x 128]
• Figure 4 on page 43 [256 x 256]
• Figure 8 on page 47 [512 x 512]
• Figure 12 on page 50 [128 x 256]
• Figure 14 on page 51 [256 x 512]
2. Setting the output board jumpers (or DIP switches) to the Expand Enable
position (as shown on
Figure 105 on page 191 ).
Restricted Output Expansion
Using Restricted Output expansion one or more input blocks are not passed
through a splitter and are therefore not boosted. For example, in the system
