Overview
The DuoDrive (Model 9870D) allows HDTV signals to be distributed throughout the home from a single source.
Component video (YPbPr), analog stereo audio, and digital audio (coaxial) sigals 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 9879 wallplate/receivers.
(Two other Cat 5 receiver styles are also available, Models 9878 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

The 9878 is a dual-gang stainless
steel wallplate with an antenna
pass-through jack. The 9880 is
an enclosed receiver ideal for
locations where a wallplate style
receiver is not practical. DC power
for each receiver is supplied
through the Cat 5 cable from the
9871’s power supply.

Cat 5 Wallplate/Receivers
All three wallplate/receiver styles deliver component video, digital and analog audio, and IR signals. The 9879
offers a wallplate format to fit a standard single-gang electrical box, and features front and rear facing IR jacks.
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 Cat 5 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.
