CB12
The OUT port can drive any of the Xantech emitter models in the 282, 283, 284 and 286 series as well as
the 286M shown in Fig. 2.NOTE: Be sure the Power Supplies, in any of these systems, are plugged into
an unswitched AC outlet. This maintains the system in "stand-by" operation so that power-on commands
can be sent to the controlled equipment.INSTALLATION (cont'd)
Fig. 3 illustrates another application of the CB12. In this case it serves as a "break-out" block for the
convenient connection of a 291 IR Receiver to a 3-conductor room-to-room cable in a larger multiroom
system. You may also use it with any other Xantech quick-connect IR Receiver, such as the 490-30, for
the same purpose.
INSTALLATION NOTES:
1. When used as a "break-out" block, you do not need to connect a power supply to the "PWR" jack on
the CB12. Power is supplied on the 3-conductor cable coming from the connecting block in the
equipment room.
Also, do not plug an emitter into the "OUT" jack in this case. To do so will prevent operation of the
emitters in the equipment room.
2. When paralleling IR receivers, a maximum of 12 is recommended. More than this may result in
unreliable operation due to the buildup of IR noise.
3. The Smart Pad™ keypads may be paralleled in larger numbers. They are not subject to the IR noise
limitation.
4. Mounting: The CB12 may be mounted on any flat surface using the double-sided adhesive tape
supplied.
