Model MRX2EA4 PCBA manual General The Model MRX2EA4 printed circuit board assembly (PCBA) contains a frequency hopping spread spectrum radio operating in the 902.4-927.6 MHz ISM frequency band. It also contains circuitry for electricity metering. When the MRX2EA4 module is installed in a plastic housing it forms a complete electricity meter. 12 MRX2EA4 units are placed in a metal cabinet together to complete an MRX2EA4 system. Installations of multiple MRX2EA4 meters comprise part of an Advanced Metering Infrastructure (AMI) system that utilizes a proprietary network architecture and protocol devised by Elster Solutions. Device specifications Mode 35.5 and 142 kbps Frequency Band 902.4 - 927.6 MHz Classification Frequency Hopping Spread Spectrum Maximum Output Power 250 mW Number of Channels 25 (per network) Channel Spacing 400 kHz Data Rate 35.5 kbps or 142 kbps 20 dB Occupied Bandwidth 325 kHz 99% Occupied Bandwidth 432 kHz Max channel dwell time within a 10 second period < 0.4 seconds within a 10 second period NOTE: The meter only transmits on one network at a time. Both are 25 channel FHSS networks. FCC and Industry Canada Compliance The radio module is manufactured directly onto the meter main circuit board, and the module is inserted into the electronic housing of the meter at manufacture. It has no user-serviceable parts. USER INFORMATION (PART 15.105) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • reorient or relocate the receiving antenna • increase the separation between the equipment and the receiver • connect the equipment into an outlet on a circuit different from that to which the receiver is connected • consult the dealer or an experienced radio/TV technician for help If you experience trouble with this equipment, please use the Return Material Authorization (RMA) feature available at the Online Customer Services at www.elstersolutions.com. Do not attempt to repair this equipment yourself unless you are replacing the entire module. COMPLIANCE STATEMENT (FCC PART 15.19 AND INDUSTRY CANADA) This device complies with part 15 of the FCC Rules and with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device.
ÉNONCÉ DE CONFORMITÉ Cet appareil est conforme à la Partie 15 des règles de la FCC et aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'utilisation de cet appareil est soumise aux deux conditions suivantes : (1) Cet appareil ne doit pas provoquer d'interférences nocives et (2) cet appareil doit accepter toutes les interférences reçues notamment celles pouvant provoquer un fonctionnement intempestif de l'appareil. ANTENNA COMPLIANCE Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. MREX2 meter: This radio transmitter has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. MREX2 meter: Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur. • On Board Printed Monopole Antenna: 0.8 dBi • PCTEL (MAXRAD) MFB9150 unity gain Fiberglass omnidirectional: 2.15 dBi • PCTEL (MAXRAD) MFB9153 3dB Fiberglass omnidirectional: 5.15 dBi • Antenex TRA9023P(NP) (white body) or Antenex TRAB9023P(NP) (black body): 3 dBi • Larsen LP800 Unity Gain Direct Feed Low Profile: 2 dBi WARNING (PART 15.21) Changes or modifications not expressly approved by Elster could void the user's authority to operate the equipment. RF RADIATION SAFETY GUIDELINES This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated to provide a separation distance of at least 20cm from all persons. COLLOCATION STATEMENT This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
