CHAPTER 2 EADER ARDWARE NSTALLATION AND PERATION CHAPTER 2 Reader Hardware Installation and Operation This chapter describes the RFID Reader and provides installation and operation information. Receiving the RFID Reader Your RFID Reader is shipped as an individual reader kit with the items listed below.
PERATION HAPTER Diagnostic LEDs The ALR-9890 - RR includes diagnostic LEDs on the face of the reader to provide easy and convenient external indication for various operating conditions: POWER (green) - indicates power is applied to the reader LINK (green) – indicates that the reader is connected to the network ACTIVE (green) –...
CHAPTER 2 EADER ARDWARE NSTALLATION AND PERATION Antenna Panel The antenna panel (opposite the reader’s I/O panel) contains four coax antenna connector ports as shown below. These are reverse-polarity TNC connectors. Also included on this panel is the Listen Before Talk (LBT) connector (unused in this model).
EADER ARDWARE NSTALLATION AND PERATION HAPTER System Assembly and Bench Test Assembling the RFID Reader system is easy. We recommend you set up the system and verify its operation in a bench test configuration before installing it in a production setting. Bench Test Configuration 1.

Repeat this process for ANT – B if required. If using the Alien Gateway software, please note that ANT 0 is selected by default when first initialized. 7. Plug power cord into power supply.
CHAPTER 2 EADER ARDWARE NSTALLATION AND PERATION Input Configuration The Reader includes four optically isolated inputs. These may be used to notify the reader of external events. The reader can react to and/or report the occurrence and timing of input events. The reader inputs are designed to accept a 5 volt signal.
EADER ARDWARE NSTALLATION AND PERATION HAPTER Bench Test Procedure The ALR 9890 – RR is a source of RF energy. When connected to a system including an antenna the radiated RF emissions must be evaluated in accordance with FCC OET Bulletin 56 “Hazards of radio frequency and electromagnetic fields”...
CHAPTER 2 EADER ARDWARE NSTALLATION AND PERATION Installation This section provides guidance for configuring components in your RFID system. You should consider the overall design of your specific system before permanently mounting the equipment. The reader is designed and certified for indoor operation.

EADER ARDWARE NSTALLATION AND PERATION HAPTER Reader should be positioned close enough to the antenna to accommodate the cable length without putting strain on the connectors. Be sure power is available at the selected reader location. 2. Install reader. Secure the reader through the two mounting holes on either flange to its mounting location (wall, post, mounting bracket) using appropriate hardware.
