shown in Figure 108 , inputs 1-16 are not split (and therefore are restricted
to outputs 1-512).
Figure 108.
Note Use the PE33016 Port expander for HD operations and the PE2x2-3G Port
expander for 3G operations.
In this example:
• For SI-33110, HI-3G, and HI-33110 input boards, the gain for
inputs 17-512 would be boosted by closing the rear-panel Output
Expand DIP switches on both frames and verifying that the on-
board jumpers for that set of inputs are in the
Expand Enable
position. The location of the boost jumpers on these input
boards is shown on
Figure 105 on page 191 . (“Base” refers to the
16 lower-numbered inputs to the main board; “Mez” refers to
the 16 higher-numbered inputs to the mezzanine board.) The
gain for inputs 1-16 must be held at unity by setting the on-
board jumper for that set of inputs to the
Force Normal position;
this overrides the rear-panel DIP switch setting for those inputs.
