Duplication and Expansion
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 ).
Partial Frame Output Duplication
As previously described in Duplication and Expansion on page 69 , the PE-
33016 Port expander can be used to provide dual outputs in blocks of 16
outputs, while the PE-33008 Port expander can be used to provide quad
outputs in blocks of 16 outputs.
Note The PE-33008 Port expander can only be used with HD and SD operations.
For example, Figure 102 shows outputs 1-16 with dual outputs and the
remainder with single outputs.
Figure 102.
Note Use the PE33016 Port expander for HD operations and the PE2x2-3G Port
expander for 3G operations.
