Expanded Systems
The PE-33016 and PE-33008 Port Expanders can be used to “combine”
outputs for an input expansion application. In Figure 19 and Figure 20 ,
a PE-33016 is downstream of the router. The router will present only
one of the two possible signals to each combiner, which will produce
two copies of that signal. Note that any unused connectors should be
terminated for optimum performance. The port expanders are
mounted in an MK-33000 Mounting Kit as described previously
( page 46 ).
Figure 19. PE-33016 used as a combiner. Only one of the input signals will be present at a time,
and this signal is duplicated.
Expanded configurations include:
1024 inputs x 512 dual outputs 1024 inputs x 1024 dual outputs
512 inputs x 1024 outputs 2048 inputs x 2048 outputs
1024 inputs x 1024 outputs
Some of these configurations are shown on the following pages. Notice
that the same port expander type is used for both downstream com-
bining (for input expansion) and upstream splitting (for output expan-
sion). All outputs are non-inverting.
