(9871, 9878)
Residential Category 5
HDTV Distribution System
TM

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.

Installing 9878 Wallplates
BE CERTAIN to connect the A cable to the A jack and the B cable to
the B jack or damage to the wallplate/receiver may occur. Adjust the
cable length compensation if the cable between the Driver and the
wallplate/receiver is over 100 feet long. Set the compensation at 1 for
cables 100-199 ft. long, and 2 for 200-299 ft. cables, etc. Do not
permanently mount the wallplate/receivers until after system testing.
Carefully connect the A and B cables to the Driver(s), power the source
components, TVs and AV receivers, and plug in 9871 power supplies
to test the system. Connect a TV to each wallplate/receiver location to
refine cable length compensation settings. Use the MINIMUM
compensation setting that still provides the best picture.
Ideally, Drivers should be located near the main home theater system,
but if they must be placed far away, compensate for losses of the long
Installing the 9871 Driver
Mount the (first) 9871 Driver to any flat vertical or horizontal surface
using the screws provided. You may wish to leave space to add
9871 Drivers to expand output capacity. Connect component video
and all audio connections desired from the source equipment to the
inputs of the 9871. Use high quality, matched sets of component
video cables, and high quality RCA cables for audio. The IR bus
jacks are only used to connect 9871 modules together.
If installing more than one 9871 Driver, connect all the bus outputs
of the first Driver to the inputs of the next Driver using high quality
patch cables or Kit 46 (sold separately), which provides convenient
male to male connectors for a more compact installation. Connect
bus jacks for all channels whether or not they will be used.
Pull two cables to each wallplate location, preferably using a different
colored cable jacket for A and B cables. Install an RJ-45 termination
on each end of every Cat 5 cable, using EIA-568B pairing (pins 1-
2, 3-6, 4-5, 7-8). If possible, use EZ RJ-45 connectors. Check each
cable with a network cable tester – CONTINUITY TESTING IS NOT
ADEQUATE – the pairs must match the EIA-568B color code.

coaxial cable by increasing the cable compensation setting by one click for each 200 feet of coaxial cable length
(see diagram below). For example, if the coaxial cable length from main system to Driver is 220 feet (1 click)
and the Cat 5 cable length to a certain wallplate is 250 feet (2 clicks), the correct Cable Length Compensation
for that wallplate is 1 + 2 = 3 clicks. Conditions vary, so it is best to verify settings using the video display that
will be installed in each location.
A pass-through F-connector is provided in case antenna connection is desired. (A separate coaxial cable must
be pulled; antenna signals are not carried on the Cat 5 cable).
Connecting to an IR network
The DuoDrive does not have an IR remote control system; it provides a discrete three-strand Cat 5 pathway
for a third party system. Connect an IR remote control system input to the Driver IR output stereo 3.5mm jack
(see example diagram below). Connect an IR receiver to each wallplate/receiver and position them appropriately
in the rooms. Do not connect any equipment to the vacant white RCA jacks marked “IR”.
