Xantech cpl94b Installation Instruction

1

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.

 Injector:

• "F" coaxial connector jacks for 

 and 

 signals.

• 3.5mm 

 stereo mini jack for quick connection of Xantech IR Receivers having 3.5mm stereo mini

plugs.

• 2.1mm 

 jack for connection of the Xantech 781RG Power Supply.

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

 Coupler:

• "F" coaxial connector jacks for 

and 

 signals.

• Two 3.5mm 

 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).

 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
