When required for large areas, or multiple-room coverage, multiple receivers can be connected in parallel on the AXlink bus. FIG. 1 AXR-RF RF Receiver AXPPWRAXMGNDDEVICEAXlinkONDATARADIOAXlink rear front Specifications Power Consumption 780 mW; ±12 VDC, 65 mA (max.) Dimensions (HWD) 1.5" x 5.09" x 5.27" (3.81 cm x 12.93 cm x 13.39 cm) Weight 10.56 oz. (299.37 g) Front Panel Components: Radio data LED AXlink LED Red LED lights to indicate the AXR-RF has received an RF signal from an AMX transmitter. Green LED that lights to indicate AXlink power/data status as follows: • 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 Device number DIP Switch RF antenna TXC antenna connector 4-wire captive-wire AXlink connector for the Central Controller provides data and nominal ±12 VDC power. 8-position DIP switch sets the device number for the AXR-RF. 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. Antenna coaxial connector Receive Frequency 418 MHz standard (other frequencies are available) Maximum Range 300 feet (91.44 m) Enclosure Molded black matte plastic Options • Alternate frequencies available • PS2.8 Power Supply 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: Rear panel P3P3 DIP Switch DIP Switch Setting for 3 validations Setting for 2 validations FIG. 2 RF validation jumper settings 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. PWR (+) AXP Central Controller AXM GND (-) 12 VDC power supply 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.
