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.
• 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).
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.

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. - Page 2 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.
- Page 3 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. If the IR receivers must operate in the vicinity of electronically ballasted Com- pact Fluorescent lamps or sunlight con- ditions, use Xantech models 291-80 or 780-80 IR receivers.
