ADVANCED MULTIROOM SYSTEMS
Fig. 4
illustrates an advanced system using a variety of connection and control techniques typical of
complex multiroom installations. It is configured as follows:
1. Both INJ94 Injectors and CPL10 Couplers are used in the remote rooms with various Xantech IR
Receivers.
As a rule of thumb, use the CPL10 with the CB12 Connecting Block when using Xantech 3-terminal
IR receivers or keypads, such as the 480-00 Dinky Link, 730-00 Smart Pad, etc. Use the INJ94 when
using Xantech IR receivers equipped with a 3.5mm quick-connect stereo mini plug, such as the 291-
00 Hidden Link and the 490-30 Micro Link.
2. Each IR receiver must be locally powered by a 781RG Power Supply as shown.
3. IR RCVR jack connections for the INJ94.Should you wish to make your own
custom connections to a mating 3.5mm stereo mini plug for this jack, follow the
terminal identifications given in the table,
Fig.5
.
4. Note that model 203-00 DC Blockers are used on the two coax leads going to
the two TV sets in the rooms
not
having IR receivers. This is a
must
to prevent
the RF inputs on the two TV sets from "shorting out" the IR control signal.
5. If an RF amplifier(s) is used anywhere in the line of coaxial cable between the CPL94B Coupler and
the INJ94 or CPL10 Injectors, you
must
use a Xantech BYPASS94 KIT to route the IR control signals
around the amplifier(s).
Where possible, place RF amplifiers ahead of the CPL94B Coupler, as shown in
Fig. 4
, instead of
using a bypass kit.
6.
Fig. 4
shows four components being controlled using two 286-00 dual emitters. This is the maximum
number of components controllable with the CPL94B. If you wish to control more, use the CPL10
