172-94X
XTRA LINK 2
REMOTE CONTROL EXPANSION KIT
The Model 172-94X is an expansion kit intended for use when installing Xtra Link 2's in more that one room.
It includes only the parts needed for each additional room, thus avoiding the unnecessary duplication of
couplers, emitters and coax jumper cables.
The 172-94X kit consists of the following supplied parts:

Power Supply
1. One 291-10 Infrared (IR) Receiver. It is placed at the remote room location to receive IR signals
-from the handheld remote controller.
2. One INJ94 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 CPL94B Coupler in the
Main room. It also allows quick connection of the 291-00 IR Receiver and 781RG Power Supply
cables.
3. One short coaxial cable. Connects the INJ94 Injector to the TV in the Remote Room.
4. A 781C-00 Power supply. This plugs into an unswitched 120V AC outlet to provide power to the
291-00 IR Receiver.
INSTALLATION
Fig. 2 shows the connections necessary when using a 172-94X expansion kit to provide remote control from
an additional room.
Begin by installing a standard 172-94 kit, for one of the remote rooms. (Refer to the owner's manual for the
Xtra Link 2 Model 172-94, for basic system connections). Next, using one of the 172-94X kits, install it into
the second remote room, making connections as shown in Fig. 2. Note that a 2-way RF splitter is used to
split the coax signal to each of the remote rooms. This splitter
must be
a DC passing type, such as the
Xantech Model 200-00.
NOTE: If RF amplifier(s) are used anywhere in the line of coaxial cable between the CPL94B Coupler and
the INJ94 Injectors, you
must use
a Xantech BYPASS94 KIT to route the IR commands around such
amplifier(s).
ADVANCED MULTIROOM HOOKUP
Fig. 3 shows an advanced system using six 172-94 plus five 172-94X Expansion Kits, in a multiroom
installation. The connection concept is essentially the same as in Fig. 2, except for the additional splitters,
RF amplifiers, etc. that need to be taken into consideration.

Fig. 2 Applying One 172-94X Kit For a Second Remote Rooms
Keep the following items in mind when installing the system:
1. Each of the RF splitters used
must be
DC passing types, such as the Xantech models 200-00 (2-way)
and the 202-00 (4-way), as shown.
2. Note that model 203-00 DC Blockers are used on the two coax leads going to the two TV sets in
the rooms
having IR receivers. This is
a must
to prevent the RF inputs on the two TV sets from
not
"shorting out" the IR control signals.
3. If an RF amplifier(s) is used anywhere in the line of coaxial cable between the CPL94B Coupler and
must
the INJ94 Injectors, you
use a Xantech BYPASS94 Kit to route the IR control signals around the
amplifier(s). See Fig. 4.
4. Where possible, place RF amplifiers ahead of the CPL94B Coupler, as shown in Fig. 3, instead of
using a bypass kit.
5. For information on how to connect and configure modulators and RF amplifiers, refer to ChannelPlus
technical information.

TROUBLE SHOOTING:
1. Perhaps the most common problem encountered is
stray IR or RF interference preventing proper operation of the controlled equipment.
Examples of such interference are:
A. Fluorescent, Compact Fluorescent, Neon or
Halogen lights, Neon Art, and light dimmers.
B. Direct or reflected sunlight.
C. Infrared security sensors (active type).
D. RF radiation from TV sets that may be close to IR
Receivers.

It may be necessary to move either the interfering

operation. Sometimes the Xantech Sun Filters will
help.

tems. Then check to see if the 291-00 operates the
satellite receiver or other components.
2. If the signal does not seem to be getting through to the
Fig. 4 Using a Xantech BYPASS94 Kit
(see text, item 3, page 2)
IR Emitters, check for shorts or opens anywhere
between the IR receivers in the remote rooms and the
emitters at the controlled equipment.
A. Remember, you must have DC continuity all the way from the IR (IR RCVR) jacks on the
Injectors, through the coax cables to the IR (emitter) jack on the coupler, without shorts to
ground.
B. Use a Xantech 179-99 Test-IR (or a Blink IR Emitter) plugged into the IR (emitter) jack on the
coupler to verify that the IR signal is being received from each room.
C. If necessary, use a multimeter in the low Ohms range to check for continuity, shorts, opens,
etc.
D. Check for open emitters by substituting a known good emitter.
3. If you have one or more TV sets in rooms where you
do not
have Xtra links and they share the same
DC passing RF splitter, you must use DC Blockers (Xantech Model 203-00) connected in the coaxial
line to each of these TV sets.
must
Refer to Fig. 3. This is a
to prevent the RF Input of such TV sets from "shorting out" the IR control
signal.
4. If a given component does not work, reposition the emitter. It may not be located directly over the
component’s IR (infrared) sensor receiving “window”. Consult the owner's manual of the unit or the
manufacturer for the exact location of the IR “window”.
