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 172-77 Xtra Link consists of the following supplied parts:
1. An infrared Receiver, Model 291-00. 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-77 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.
4. One Dual IR Emitter, Model 284M. The emitters on this device allow control of two infrared remote
controlled audio/video components.
5. A 781C-77 Power supply. This plugs into an unswitched 220-240 VAC outlet to provide power to the
291-00 IR Receiver.
CONNECTIONS
The Xtra Link system uses the coaxial cable that
carries the TV RF signal from the source equip-
ment in the main room to the remote room, to
send the IR control signals back to the source
equipment. The coaxial cable may be up to one
mile in length.
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
the line of coaxial cable between the CPL77
Coupler and the INJ77 Injector, you must use a
Xantech BYPASS77 KIT to route the IR com-
mands around the amplifier(s).

Summary
2 172-77 When using more than one Xtra Link for more rooms, be sure the RF splitters you use are DC passing types,such as Xantech part number 04027500 (2-way). Refer to Fig. 3 . INSTALLING THE 291-00 IR RECEIVER Insert the cable mini plug attached to the 291-00 into the jack marked "IR RECEIVE...

4 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 upinterference. This interference may, in severe cases, prevent the system from working. Common examples of interference are: • RF radiation from the TV set on which th...
