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 Guide

AXR-RFRF Receiver

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.

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.
