SYSTEM CONFIGURATION 4
ZR-4 MULTIZONE RECEIVER WITH EXTERNAL
RS-232 CONTROL SYSTEM
The ZR-4 MultiZone Receiver can be monitored and
controlled by an external control system that uses
RS-232C serial communication.
RS-232 CONNECTION
A single 3.5mm stereo female-tip positive connector is used for RS-232C serial communication from an external control system such as AMX ® .
Refer to appendix at www.nilesaudio.com/techsupport for RS-232C integration.
SYSTEM CONFIGURATION 5
ZR-4 MULTIZONE RECEIVER WITH TWO KEYPADS IN A ZONE
Any zone of the ZR-4 MultiZone Receiver can be expanded to contain two Keypads. This is especially convenient in large rooms or in
bedrooms where a Keypad is desired on each side of the bed.
NILES ZR-KE KEYPAD EXPANDER
The ZR-KE Keypad Expander enables the use of two Keypads per zone. The RJ-45 terminated CAT-5 cable from the ZR-4 MultiZone
Receiver’s Keypad Port is connected to the input of the ZR-KE. The two keypads are then connected to the outputs on the ZR-KE with
CAT-5 cable.
NOTE: THE ZR-KE HAS THREE OUTPUTS, BUT ONLY TWO CAN BE USED FOR KEYPADS WITH THE ZR-4 MULTIZONE RECEIVER. ONE ZR-KE CAN BE USED FOR EACH
ZONE, INCLUDING ADDITIONAL SLAVE ZONES WHEN A SECOND ZR-4 MULTIZONE RECEIVER KIT IS USED TO EXPAND THE SYSTEM TO EIGHT ZONES.
