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.

program do not match the devices found.
• Three blinks/second indicates there is an AXlink communication

power is On) or the Axcess program is not loaded.

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.
Wiring Specifications
Wire size Maximum wiring length
18 AWG 1805.7 feet (550.37 m)
20 AWG 1142.4 feet (348.20 m)
22 AWG 712.2 feet (217.07 m)
24 AWG 448.9 feet (136.82 m)
If you install the AXR-RF farther away from the Central Controller than
recommended in the Wiring Specifications table, an auxiliary ±12 VDC
power supply is required for operation.
Wiring the AXR-RF
The AXR-RF uses a rear 4-pin AXlink connector for power and data.
Power can be supplied by Central Controller's AXlink cable, or with an
optional auxiliary ±12 VDC power supply.
Using the AXlink 4-pin connector for data and power
Connect the Central Controller's AXlink connector to the AXlink connector
(male) on the rear panel of the AXR-RF for data and ±12 VDC power.

Using the AXlink 4-pin connector with an external ±12 VDC power supply
Use an auxiliary ±12 VDC power supply when the distance between the
Central Controller and AXR-RF exceeds the limits described in the Wiring
Specifications table. To use an external power supply, connect the Central
Controller's AXlink connector to the AXlink connector on the rear of the
AXR-RF, as shown in FIG. 4.

Installing the AXR-RF
1. Set the device DIP switch to assign an AXlink device code to the unit.
2. Install the wiring for the AXlink bus.
3. Position the AXR-RF in the location where it will be used. Place the
receiver close to, or in the middle of, the area to be covered. It is
recommended that you mount the unit where the antenna is away
from metal obstructions.
4. Extend the antenna vertically for best reception. If it is necessary to
place the antenna in a remote position, use up to 6 ft. (2 m) of
RG-174 coax cable.
5. Connect the AXR-RF to the Central Controller with the AXlink cable.
NOTE: To avoid potential problems with Axcess processing, do not install
two or more AXR-RF devices, using the same RF frequency, in one
system. The AXR-RF is available in frequencies other than 418 MHz (on
request).
6. Locate the green AXlink LED on the front panel and verify that it
flashes once per second. If so, the AXR-RF is communicating
properly with the Central Controller system.
If the LED is on and not flashing, disconnect the AXlink connector
and recheck all AXlink wiring connections. Reconnect the AXlink
connector to the AXR-RF and verify the LED is flashing once per
second.

CAUTION: Do not connect the wire from the PWR (+) terminal on the
Central Controller to the PWR (+) terminal on the AXR-RF when you
connect an external power supply. Do not connect power to the AXR-RF
until the wiring is complete.
Connect only the GND (-) wire on the AXlink connector when using an
auxiliary ±12 VDC power supply. Do not connect the PWR (+) wire to the
AXlink connector's PWR (+) terminal on the Central Controller side of the
connector.
