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.
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.
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.

• Dimensions: 2-3/16" x 1-3/8" x 7/8" (case).
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).

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 techniques typical of
complex multiroom installations. 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 29100 Hidden Link and the 490-30 Micro Link.
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
custom connections to a mating 3.5mm stereo mini plug for this jack, follow the
terminal identifications given in the table, Fig.5.
4. Note that model 203-00 DC Blockers are used on the two coax leads going to
not
the two TV sets in the rooms
having IR receivers. This is a

the RF inputs on the two TV sets from "shorting 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
must
the INJ94 or CPL10 Injectors, you
use a Xantech BYPASS94 KIT to route the IR control signals
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 286-00 dual emitters. This is the maximum
number of components controllable with the CPL94B. If you wish to control more, use the CPL10
