Restricted Input Expansion
In this case one or more output blocks are not combined and are there-
fore not boosted. For example, in the system shown in
Outputs 1-16 of Frame 0 are not combined (and therefore are restricted
to inputs 1-512).
Figure 64.
In this example:
• For SO-33110/33011 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 chassis 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
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 chassis and verifying that the on-
board DIP switches for those outputs are closed. The loca-
tion of the DIP switches for these boards is shown on
. 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 out-
puts.
