Installation Guide
AXR-RF
RF Receiver
Overview
The AXR-RF Radio Receiver provides wireless reception of AMX radio
frequency (RF) transmitters. The AXR-RF connects to an Axcess Central
Controller with an AXlink, 4-pin captive-wire connector. When required for
large areas, or multiple-room coverage, multiple receivers can be
connected in parallel on the AXlink bus.
Installation
Configuring the AXR-RF
Use the eight-position DIP switch on, the rear of the AXR-RF, to set the
device number. A device number is assigned to devices connected to the
AXlink bus. Every device on the bus must have a unique device code. The
device number must match the device assignment in the Axcess program.
AMX assigns device numbers in three groups:
•
Axcess Control Cards: 1 - 95
•
Axcess Bus Boxes: 96 - 127
•
Axcess Panels/Receivers: 128 - 255
Setting the DIP Switch
Locate the device DIP switch on the rear panel of the AXR-RF and set it to
the desired binary device number. The device number is set by the total
value of DIP switch positions that are ON (down).
NOTE
: If you change the device number, remove and reconnect the AXlink
connector. This enters the new device number into memory.
Although the AXR-RF is a bus device, it should be numbered in the 128-255
range, because it is a receiver.
Setting the RF Validation Level
An RF transmitter must send repetitions of data for the receiver to accept it
as valid data. In some installations, interference and physical structures
may interfere with the receiver's ability to detect the transmitted signal. The
signal may become distorted. The receiver can be set to use either two or
three repetitions of sequential signals to validate and accept the signal
data. To set the receiver's RF level.
1.
Locate jumper pins labeled
P3
on the circuit board.
2.
Position the P3 RF validation jumper to select the number of valid RF
data repetitions to be accepted, as shown in FIG. 2:
Wiring Guidelines
The AXR-RF requires regulated ±12 VDC power to operate properly. The
Central Controller supplies power via the AXlink cable. The maximum
wiring distance between the Central Controller and AXR-RF is determined
by power consumption, supplied voltage, and the wire gauge used for the
cable. The table below lists wire sizes and maximum lengths allowable
between the AXR-RF and Central Controller. The maximum wiring lengths
for using AXlink power are based on a minimum of ±13.5 VDC (no load
voltage), available at the Central Controller's power supply.

Front Panel Components:
Radio data LED
Red LED lights to indicate the AXR-RF has received an RF signal
from an AMX transmitter.
AXlink LED
Green LED that lights to indicate AXlink power/data status as fol-
lows:
• One blink/second indicates power is active and AXlink
communication is working.
• Two blinks/second indicates the devices specified in the main
program do not match the devices found.
• Three blinks/second indicates there is an AXlink communication
error
• Full on indicates there is either no AXlink control/activity (but the
power is On) or the Axcess program is not loaded.
Rear Panel Components:
AXlink connector
4-wire captive-wire AXlink connector for the Central Controller pro-
vides data and nominal ±12 VDC power.

8-position DIP switch sets the device number for the AXR-RF.
RF antenna
Receiving antenna screws into the TXC antenna connector. If it is
necessary to place the antenna in a remote position, use up to 6 ft.
(2 m.) of RG-174 coax cable as an extension. Extend the antenna
vertically during use.
