DESCRIPTION
The INJ94 injects and the CPL94B extracts IR control signals on the same coaxial cable that
carries TV or other RF signals, using the patented Xtra Link™ principle.
MODELS
INJ94 INJECTOR & CPL94B COUPLER
CPL94B Coupler:
• "F" coaxial connector jacks for SAT/VCR
and REMOTE TV signals.
• Two 3.5mm EMITTER mono mini jacks,
with 470 Ohm series resistors, for quick
connection of two Xantech single or dual
emitters.
• Dimensions: 2-3/16" x 1-3/8" x 7/8" (case).
SPECIFICATIONS
INJ94 Injector:
• "F" coaxial connector jacks for TV and
INPUT signals.
• 3.5mm IR RCVR stereo mini jack for quick
connection of Xantech IR Receivers having
3.5mm stereo mini plugs.
• 2.1mm +12 V jack for connection of the
Xantech 781RG Power Supply.
• Dimensions: 2-3/16" x 1-3/8" x 7/8" (case).
TROUBLE SHOOTING
A. Perhaps the most common problem is
stray IR or RF interference entering IR
receivers, preventing proper operation of
the controlled equipment.
Examples of such interference are:
• Fluorescent, Compact Fluorescent,
Neon or Halogen lights, Neon Art, or
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.
B. If the IR receivers must operate in the
vicinity of electronically ballasted Compact
Fluorescent lamps or sunlight conditions,
use Xantech models 291-80 or 780-80 IR
receivers. These are specifically designed
to reject most of this type of interference.
C. 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 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.
D. If a given component still does not work,
reposition the emitter. It may not be located
directly over the component’s IR (infrared)
receiving "window". Consult the owner's
manual of the unit or the manufacturer for
the exact location of the infrared "window".

Located in Remote Rooms, the INJ94 injects the remote control signal into the room-to-room
coaxial cable (along with the TV signal) and passes it to a CPL94B or CPL10 Coupler in the
Main Room or equipment area. It is designed specifically so that Xantech IR Receivers
having 3.5mm stereo mini plugs may be plugged in directly to the IR RCVR jack. The 2.1mm
+12 V coaxial jack also provides quick connection of the Xantech 781RG power supply.
Located in the Main Room or equipment area, the CPL94B extracts the remote control signal
from the coaxial cable and passes it to the emitters that control the source equipment. Any
of the Xantech single or dual emitters may be plugged directly into the 3.5mm mono mini
EMITTER jacks, in any combination, for control of up to four components.

2. Each IR receiver must be locally powered
by a 781RG Power Supply as shown.
3. IR RCVR jack connections for the INJ94.
Should you wish to make your own cus-
tom connections to a mating 3.5mm ste-
reo mini plug for this jack, follow the termi-
nal identifications given in the table, Fig.
5, below:
4. Note that model 203-00 DC Blockers are
used on the two coax leads going to the
two TV sets in the rooms not having IR
receivers. This is a must to prevent the
RF inputs on the two TV sets from "short-
ing out" the IR control signal.
5. If an RF amplifier(s) is used anywhere in
the line of coaxial cable between the
CPL94B Coupler and the INJ94 or CPL10
Injectors, you must use a Xantech BY-
PASS94 KIT to route the IR control sig-
nals around the amplifier(s).
Where possible, place RF amplifiers ahead
of the CPL94B Coupler, as shown in Fig.
4, instead of using a bypass kit.
6. Fig. 4 shows four components being
controlled using two 286M dual emitters.
This is the maximum number of
components controllable with the CPL94B.
If you wish to control more, use the CPL10
instead, along with a suitable connecting
block, such as the 789-44 or 791-44. See
the CPL10 installation instructions for
details.
7. For information on how to connect and
configure modulators and RF amplifiers,

information.

INSTALLATION
FIG. 3 illustrates a typical installation using
two INJ94's and a CPL94B in a three room
system.
When configuring these types of systems,
keep the following factors in mind:
1. 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.
2. When configuring multiple rooms, be sure
the RF splitters used are DC passing
types, such as Xantech Models 200-00
(2-way) and 202-00 (4-way). Refer to
Figs. 3 and 4.

ADVANCED MULTIROOM SYSTEMS
Fig. 4 illustrates an advanced system using
a variety of connection and control tech-
niques typical of complex multiroom installa-
tions. It is configured as follows:
1. Both INJ94 Injectors and CPL10 Couplers
are used in the remote rooms with various
Xantech IR Receivers.
As a rule of thumb, use the CPL10 with the
CB12 Connecting Block when using
Xantech 3-terminal IR receivers or
keypads, such as the 480-00 Dinky Link,
730-00 Smart Pad, etc. Use the INJ94
when using Xantech IR receivers equipped
with a 3.5mm quick-connect stereo mini
plug, such as the 291-00 Hidden Link and
the 490-30 Micro Link.
