AXR-RF RF Receiver (AxLink)
Overview
The AXR-RF Radio Receiver (FG7820-XXX) 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.
Specifications
The standard frequency for the AXR-RF is 418 MHz, but other frequencies are
available. See the Product Specifications table below:
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 P3 (FIG. 2) on the circuit board.
2. Position the P3 RF validation jumper to select the number of valid RF data
repetitions to be accepted:
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.
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.

Front Panel Components
•RadiodataLED: Red LED lights to indicate the AXR-RF has received an RF
signal from an AMX transmitter.
•AXlinkLED: Green LED that lights to indicate AXlink power/data status
as follows:
• 1 blink/second indicates power is active and AXlink
communication is working.
• 2 blinks/second indicates the devices specified in the
main program do not match the devices found.
• 3 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 provides data and nominal ±12 VDC
power.
• Device DIP Switch: 8-position DIP switch sets the device number for the AXR-
RF.
• RF antenna Receiving antenna screws into the 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 exten-
sion. Extend the antenna vertically during use.

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 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 Connector With an External 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. 3.
Note: 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.
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.
