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.

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.

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. Installing the AXR-RF Wiring 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.
