Restricted Output Expansion

In this application one or more input blocks are not passed through a

splitter and are therefore not boosted. For example, in the system shown

in

Figure 68

, inputs 1-16 are not split (and therefore are restricted to

outputs 1-512).

Figure 68.

In this example:

• For SI-33110 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 chassis 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

page 132

. (“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.
