CHAPTER 3 | INSTALLATION AND OPERATION
SPEAKER WIRE TERMINATION
Install the four supplied phoenix connectors into the speaker outputs
on the CP-1650. Connect the positive and negative wires for each audio
channel output, keeping the proper orientation of positive and negative
signals for each speaker connection. Typically, two-conductor speaker wire
uses red to denote positive and black to denote negative. Some types
of wire indicate positive with a line running through the insulation. Four-
conductor wire can also be used. This has four separated wires in one
outer jacket, making it possible to run a single speaker wire to a zone
for its pair of speakers. This type of wire typically uses red and black for
one speaker and white as positive and green as negative for the second
speaker.
IR CONTROL OF CP-1650
A discrete set of IR codes is available within the RTI Integration Designer
programming software or on the RTI website (accessible to RTI dealers
only). A 3.5mm mono mini jack labelled IR In is located on the rear of the
CP-1650. All IR commands received are looped out through the IR Out
jack.
RS-232 CONTROL OF CP-1650
A DB-9 jack offers RS-232 control of the CP-1650 from an RTI or third-
party home automation control system or a PC running a hyperterminal
program. A set of RS-232 codes is available within the RTI Integration
Designer programming software or on the RTI website (accessible to RTI
dealers only).
