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
not having IR receivers. This is a must to prevent the RF inputs on the two TV sets from
"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
the INJ94 Injectors, you
must 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
