XTRA LINK® 2
REMOTE CONTROL EXTENSION SYSTEM
The Xtra Link 2 system provides full remote control operation of a satellite receiver, cable box or VCR from
a second room by sharing the coaxial cable connecting your video equipment to this second room’s TV.
The 172-78 Xtra Link consists of the following supplied parts:
1. One 291-10 Infrared Receiver. It is placed at the
remote room location to receive IR signals from the
handheld remote controller.

2. One INJ77 Injector. This unit, located in the Remote
Room, injects the remote control signal into the room-
to-room coaxial cable (along with the TV signal) and
passes it to the CPL77 Coupler in the Main room. It
also provides quick connection of the 291-00 IR Re-
ceiver and 781C-78 Power Supply cables.

3. One CPL77 Coupler. Located in the Main Room, this
Coupler extracts the remote control signal from the
coaxial cable and passes it to the emitters that control
your source equipment. In addition, the CPL77 con-
tains a 2-way RF splitter so that the TV signal can be
fed to a local TV.

device allow control of two infrared remote controlled
audio/video components.

5. One 781C-78 Power Supply. This plugs into an
unswitched 220-240 VAC outlet to provide power to
the 291-00 IR Receiver.

If you already have a coaxial cable connecting
your video equipment with a remote room, your
current hookup should be similar to Fig. 1. If it
isn't, run a single length of RG59 or preferably
RG6 cable from the Main Room to the Remote
Room.

NOTE: If RF amplifier(s) are used anywhere in

mands around the amplifier(s).

INSTALLING THE XTRA LINK 284M DUAL IR EMITTER
Plug the 284M Dual IR Emitter into the jack marked "EMITTER" on the CPL77 Coupler in the Main Room.
The 284-10 emitters should be installed directly to the infrared sensor "window" on the front panel of the
satellite receiver, VCR, cable box, etc. Simply remove the paper backing exposing the adhesive surface
of each emitter and apply them to the center of the sensor window.
NOTE: Although the 284M appears dark to the eye, it is transparent to infrared. Positioning the 284M
directly over the infrared window(s) of the component(s) will not block direct IR control from a handheld
remote.
OPERATION
To use the Xtra Link Remote Control Extension System, simply point your handheld remote control(s) at
the 291-00 IR Receiver and press the desired button. A red LED on the front of the 291-00 will indicate the
reception of your infrared command.
NOTE: The maximum usable distance between your IR remote and the 291-00 Receiver will vary for each
remote and might be shorter than when directly used in the room containing the satellite receiver or other
IR controlled devices.
The 172-78 system may be left on continuously as it does not affect the normal operation of the remote
controlled device(s) and consumes very little energy.

HOW TO AVOID PROBLEMS
In rare cases, the 291-00 IR Receiver may have to be moved to a different location if the unit is picking up
interference. This interference may, in severe cases, prevent the system from working.
Common examples of interference are:
• RF radiation from the TV set on which the 291-00 IR Receiver may have been placed.
• Direct or reflected sunlight.
• Fluorescent, Compact Fluorescent, Neon, Neon Art, Halogen lights or light dimmers.
• Infrared security systems.
You can confirm the source of the interference by temporarily turning off the remote room TV set, isolating
the 291-00 Receiver from all sunlight and turning off all lights, light dimmers and Infrared security systems.
Then check to see if the 291-00 operates the satellite receiver or other components.
If the 291-00 still does not work, reposition the 284M Emitter(s). It may not be located directly over the
component’s infrared receiving "window". Consult the owner's manual of the unit or the manufacturer for
the exact location of the infrared "window".
IMPORTANT: For installations involving more than two remote rooms, use the services of a competent
professional audio/video installer experienced in infrared remote control systems.
