Expanded Systems
The PE-33016, PE-2X2 3G, and PE-33008 Port expanders can be used to
combine outputs (SD and HD options) for an input expansion application.
The PE-2X2 3G is required for 2X2 expansion in 3G systems, but will also
work for SD and HD systems. The PE-33016 and PE-33008 will not work
with 3G systems. In
Figure 35 and Figure 36 , a PE-33016 or PE-2X2 3G is
downstream of the router. The router will present only one of the two pos-
sible signals to each combiner, which will then produce two copies of that
signal. Only one of the input signals will be present at a time and this signal
is then duplicated. Any unused connectors should be terminated for
optimum performance.
The port expanders are mounted in an MK-33000 Mounting Kit as
described previously (
Figure 33 on page 73 ).
