INSTALLATION
Fig. 2 illustrates a typical in-
stallation using the CB12 in a
multiroom IR repeater sys-
tem. In this case a Xantech
291 Hidden Link™ IR Re-
ceiver is used to control a
Satellite Receiver and a VCR
in a cabinet behind closed
doors in Room 1. Control of
the same equipment is ac-
complished from two other
rooms with a Xantech 780-10
J-box IR Receiver and a
Smart Pad™ keypad, by us-
ing the 3-terminal "VGS" con-
nector on the CB12
(V=+12Volts, G=Gnd., S=IR
Signal). When connecting a system, follow this diagram carefully:
When you use more than 1 keypad and one IR receiver together in a system, use the high current power
supply, model 782-00, in place of the 781RG.
