Overview
The DuoDrive (Model 9870) allows HDTV signals to be distributed throughout the home from a single source.
Component video (YPbPr), analog stereo audio, and digital audio (coaxial) signals are included in each two-cable
Cat 5 pathway. By connecting IR remote control systems to the DuoDrive system, users can easily control the source
equipment from other rooms in the house. IR receiver and emitter products are not included with the DuoDrive.
System Design
The DuoDrive is comprised of one Model 9871 RCA-to-Category 5 Driver and two Model 9878 wallplate/receivers.
(Two other Cat 5 receiver styles are also available, Models 9879 and 9880.) These products enable distribution of
audio, video and IR control signals on Cat 5 cable runs of up to 1,000 feet. The buffered Cat 5 bus outputs on each
9871 drive one or two wallplate/receivers. To expand output capacity of the system, connect together an unlimited
number of 9871 Drivers using Kit 46, included with each Driver. High quality RCA patch cables can also be used
for expansion.

Rough-In
Wallplate/receivers are normally placed on the wall behind the television sets or entertainment centers remoted off
the main home entertainment system. Set a plaster ring at each wallplate location. Pull two runs of good quality
Category 5, 5e or 6 UTP cable from the head-end location to each wallplate/receiver location. Be careful not to
pinch, kink, or tightly staple the cable. Mark both ends of the cables in each set A and B, or use two different jacket
colors of UTP cable for A and B. It will be helpful to mark the cable length of each run at the wallplate/receiver end
because you will have to adjust the cable length compensation when installing each wallplate/receiver.
