CPL10
5. If an RF amplifier(s) is used anywhere in the line of coaxial cable between the CPL10 Coupler and the
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.

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 equip-
ment.
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.
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”.
