Wiring Diagrams
The diagrams on the following pages show
examples of common ways to connect your
set-top to your HDTV, VCR, and home
theater receiver. However, these diagrams
do not show every possible combination of
devices. Please consult the user’s guides
that came with your other devices for
further information.
HDTV Formats
Most HDTVs include YPbPr connectors
for component video inputs, and your
Explorer 3170HD Set-Top includes a
YPbPr cable for these inputs.
However, some HDTVs only have RGB
inputs. If you have one of these HDTVs,
you may need a connection converter.
Audio Output
To hear stereo sound, you must do one of
the following:
• Connect stereo audio cables from the
AUDIO OUT LEFT and RIGHT
connectors on the set-top to the
AUDIO IN LEFT and RIGHT
connectors on your HDTV
• Connect an RCA cable from the
DIGITAL AUDIO OUT on your set-
top to the DIGITAL AUDIO IN on
your HDTV (if equipped) or stereo
receiver
In addition, you may also connect an
S-Video cable from the S-VIDEO OUT
connector on the set-top to the S-VIDEO
connector on the HDTV or VCR. How-
ever, the S-Video connection does not
supply audio. You must also use audio
cables with the S-Video cable.
If you connect the set-top to your HDTV
using only the coaxial cable at the CABLE
OUT connection, your HDTV will not
receive stereo sound from your set-top.
Note: S-Video and coaxial cables only
deliver SDTV programming. They do not
deliver HDTV programming.
Some of the cables shown in the diagrams
may not be included with your Explorer
Set-Top.
Important: Be sure to follow the steps
listed in Connecting the Set-Top. If you
do not do so, your set-top will not be
authorized to receive digital services.
Check with the store where you purchased
your set-top, or contact Scientific-Atlanta
toll-free at 866-212-2141.
Also, some SDTVs include YPbPr inputs.
Your set-top will not function correctly
with these inputs.
