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		291-00 IR Receiver
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.
4.	One 284M Dual IR Emitter. The emitters on this

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).
