INSTALLATION
Fig. 2 illustrates a simple installation using CPL10 Couplers in an IR repeater system. Control of a satellite
receiver and a VCR from two remote rooms is accomplished over the same coaxial cable that carries the
TV signal. When configuring this type of system, keep the following items in mind:
1. CPL10's may be used for both injecting and extracting the IR signal on the coax at the IR receiver
and
equipment ends, as shown.
2. REMOTE ROOM 1 is an example of how any 3-lead Xantech IR receiver (or keypad) may be used in
an Xtra Link type system. A CB12 Connecting Block makes the necessary connections between the
three leads of the 480-00 "Dinky Link" IR Receiver, the 781RG Power Supply and the CPL10 Coupler.
3. REMOTE ROOM 2 shows the use of a 291-10 IR Receiver and an INJ94 Injector. Use the INJ94
instead of the CPL10 any time you use a Xantech IR receiver equipped with a quick connect stereo
mini plug.

4. The 2-way RF splitter used in the equipment area must be a DC Passing type, such as the Xantech
Model 200-00, as shown. This ensures that the IR coded pulses are passed through the RF splitter
to the CPL10 to drive the 286-00 emitters.
5. Be sure the CPL10 is placed between the source equipment (in this example a VCR) and the 2-way
RF splitter as shown.
6. Room-to-room coaxial cable lengths, exclusive of RF signal considerations, may be up to one mile in
length, using RG-6, for successful IR signal transmission.
ADVANCED MULTIROOM SYSTEMS
Fig. 3 illustrates an advanced system using a variety of connection
and control techniques typical of
complex multiroom installations. It is
configured as follows:
1. Both CPL10 Couplers and
INJ94 Injectors are used in the
Six Remote Rooms, each configured in the same manner as shown in Fig. 2

INJ94 Injectors (or the CPL10's used as Injectors), you
must
use a Xantech BYPASS94 Kit to route
the IR control signals around the amplifier(s) as shown in Fig. 4.
6. Where possible, place RF amplifiers ahead of the CPL10 Coupler, as shown in Fig. 3, instead of using
a bypass kit.
7. To drive the necessary emitters and devices, a 789-44 Connecting Block is connected to the IR jack
on the CPL10 to make four emitter jacks available.
NOTE: NO POWER SUPPLY IS NECESSARY ON THE 789-44 WHEN IT IS USED ONLY AS AN
EMITTER EXPANSION BLOCK, AS IN THIS CASE.
8. Fig. 3 also shows a Xantech SR21 Speaker Relay Module used as an IR Router so that control of two
satellite receivers (or other products having identical IR control codes) can be addressed individually
from any remote room location. (Refer to the SR21 Installation Instructions for information on using
it for IR routing).
In this type of operation, you may program a learning device, such as the Xantech URC-1 Universal
Learning Remote Control or the Smart Pads, with sequence commands (macros). These sequences
would issue channel commands to the remote room TV's to switch them to the modulator channel for
the desired satellite receiver along with the corresponding IR router command for the SR21 -- all with
one button press. You would then program other buttons with the satellite receiver commands.
To program sequences, refer to instructions for the learning device.
9. For information on how to connect and configure modulators and
®
RF amplifiers, refer to Channel Plus
technical information.

TROUBLE SHOOTING
1. Perhaps the most common problem encountered is stray IR or RF
interference preventing proper operation of the controlled equipment.
Examples of such interference are:
• Fluorescent, Compact Fluorescent, Neon or Halogen lights,
Neon Art, and light dimmers.
• Direct or reflected sunlight.
• Infrared security sensors (active type).
• RF radiation from TV sets that may be close to IR Receivers.
It may be necessary to move either the interfering source or the IR
receiver to achieve proper operation. Sometimes the Xantech Sun
Filters will help.
Fig. 4 Using a Xantech
BYPASS94 Kit
2. Check for shorts or opens anywhere between the IR receivers in the remote rooms and the emitters
at the controlled equipment.
• Remember, you must have DC continuity all the way from the IR (IR RCVR) jacks on the Injectors,
through the coax cables to the IR (emitter) jack on the coupler, without shorts to ground.
• Use a Xantech 179-99 Test-IR plugged into the IR (emitter) jack on the coupler to verify that the IR
signal is being received from each room.
• If necessary, use a multimeter in the low Ohms range to check for continuity, shorts, opens, etc.
• Check for open emitters by substituting a known good emitter.
3. If a given component does not work, reposition the emitter. It may not be located directly over the
component’s IR (infrared) sensor receiving “window”. Consult the owner's manual of the unit or the
manufacturer for the exact location of the IR “window”.
