Partial Chassis Output Duplication

As previously described (starting on

page 43

), 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.

For example,

Figure 62

shows outputs 1-16 with dual outputs and the

remainder with single outputs.

Figure 62.

In this example:

• For SO-33110/33011 and HO-33110/33011 output boards,

the gain for outputs 1-16 would be boosted by closing the

rear-panel Input Expand DIP switch and verifying that the

on-board jumper for that set of outputs is in the “Expand

Enable” position. The location of the boost jumper on these

output boards is shown on

page 128

. The gain for outputs

17-256 must be held at unity by setting the on-board jumpers

for that set of outputs to the “Force Normal” position; this

overrides the rear-panel DIP switch setting for those out-

puts.

• For HO-33120/33121 output boards, the gain for outputs 1-

16 would be boosted by closing the rear-panel Input Expand

DIP switch and verifying that the on-board DIP switch for

those outputs is closed. The location of the DIP switches for

these boards is shown on

page 129

. The gain for outputs 17-

256 must be held at unity by opening the on-board DIP

switches for that set of outputs; this will override the rear-

panel DIP switch setting for those outputs.
