NOTES:
a) Each zone of the ZPR68-10 can be set to its own individual Group Code. This may be useful when
the system requirements so dictate.
b) The Code Group Number assigned and preset at the factory for each zone of the ZPR68-10 is 68.
c) Since other Xantech IR controlled models are assigned and preset at the factory to different Code
Groups, it is unlikely that you will ever need to change the Code Group on the zones of the ZPR68-
10 away from the factory preset number of 68.
18. A, B, C buttons. These operate special control functions on other Xantech IR controlled products.
19. Code Group Setting Switches. These rotary switches are for setting and selecting the specific IR
Remote Control Code Groups.
These must be set to 68 to work with the ZPR68-10!
Refer to the INSTALLER INSTRUCTIONS that come with the RC68+ for Code Group Setting
Procedures.
20. Battery Compartment. Holds two 1.5V "AA" batteries that power the RC68+. Use Alkaline batteries
for longest life. Slide cover in the direction of the arrow for removal.
INSTALLATION
Fig. 6 shows a typical installation of a ZPR68-10 utilizing all 8 source inputs and all 6 zone outputs.
• A variety of Xantech IR receivers and keypads control the zones and the source equipment.
• The STATUS terminal on each zone provides zone ON/OFF indication on their respective IR receivers
and keypads.
• Two Xantech PA640 Power Amplifiers drive the stereo pairs of speakers in each of the six zones.
• The common CO terminal provides AC power ON/OFF management for the PA640's and for the common
sources through GATEKEEP-IR
TM
.
Note: All source components in this typical system must have their ON/OFF function controlled by IR. See
the GATEKEEP-IR Installation Instructions for all GATEKEEP-IR programming procedures.
CONNECTION PROCEDURE
The following procedure is based on Fig. 6, and assumes that all rooms in the house, where remote
controlled A/V signals are desired, have been pre-wired with home runs of 4-conductor cable, coaxial cable
and speaker wires. In addition, all IR receivers, keypads and speakers have been connected in each room,
and the system is ready for installation of the ZPR68-10 and other components.
CAUTION: Be sure no power is applied to any of the components until all connections are made.
1. Make connections from each of the zone 4-conductor cables to the ZONE CONTROL - IR INPUTS
terminals.
Note that in Fig. 6 only zones 2 & 3 have IR
receivers - the rest are keypads. This assumes
the use of learning remotes capable of macro
(sequence) programming for GATEKEEP-IR func-
tions.
SPECIAL NOTE: When using long lengths (>50
feet) of inter-room shielded cable, it may be
necessary to connect a 470 Ohm 1/8 Watt resistor
between Input (signal) and Gnd at the IR input terminals of the ZPR68-10. The resistor discharges
the cable capacitance more quickly, allowing IR codes of high bit rates to pass without data loss for
consistent command executions. See Fig. 7.
