6A.
If your application is two-way (that is, one pair of audio/video signals going one
direction and one pair going the other direction):
Run four RCA phono cables from
each Balun to the attached device:
• one from the Balun’s VIDEO 1 port to the device’s VIDEO AUX IN port;
• one from the Balun’s VIDEO 2 port to the device’s VIDEO AUX OUT port;
• one from the Balun’s AUDIO 1 port to the device’s AUDIO IN port; and
• one from the Balun’s AUDIO 2 port to the device’s AUDIO OUT port.
(These cables must have RCA male connectors on the Balun end.) Make sure
that the VIDEO IN and AUDIO IN ports of the device on one end of the link
are connected to the VIDEO OUT and AUDIO OUT ports of the device on
the other end. Refer to Figure 3-1.
6B.
If your application is one-way (that is, both pairs of audio/video signals going the same
direction):
Run four RCA phono cables from each Balun to the attached
devices:
• On the source end, these cables should go from the Balun’s VIDEO and
AUDIO ports to the devices’ VIDEO AUX OUT and AUDIO OUT ports.
• On the destination end, these cables should go from the Balun’s VIDEO
and AUDIO ports to the devices’ VIDEO AUX IN and AUDIO IN ports.
(These cables must have RCA male connectors on the Balun end.) Refer to
Figure 3-1.

7. Connect one end of a UTP cable into each Balun’s RJ-45 modular jack. To
carry the first video signal, these cables must carry a wire pair pinned to RJ-45
Pins 7 and 8. To carry the second video signal, the cables must carry a pair
pinned to Pins 1 and 2. To carry the first audio signal, the cables must carry a
pair pinned to Pins 4 and 5. To carry the second audio signal, the cables must
