In this example:
• For SO-33110/33011, HO-3G, and HO-33110/33011 output
boards, the gain for outputs 17-512 would be boosted by closing
the rear-panel Input Expand DIP switches on both frames and
verifying that the on-board jumpers for that set of outputs are
in the Expand Enable position. The location of the boost jumper
on these output boards is shown on Figure 105. The gain for
outputs 1-16 must be held at unity by setting the on-board
jumper for that set of outputs to the Force Normal position; this
overrides the rear-panel DIP switch setting for those outputs.
• For HO-33120/33121 output boards, the gain for outputs 17-512
would be boosted by closing the rear-panel Input Expand DIP
switches on both frames and verifying that the on-board DIP
switches for those outputs are closed. The location of the DIP
switches for these boards is shown on Figure 106. The gain for
outputs 1-16 must be held at unity by opening the on-board DIP
switch for that set of outputs; this will override the rear-panel
DIP switch setting for those outputs.
