CUG RFW-201, Revision 1 3 RFW-201 User’s Guide 1 About the RFW-201 The RFW-201 is a radio communications device designed for use in water meters. The RFW-201 provides a 915 MHz radio interface to an RF mesh network. The RFW-201 operates from a 3.6V lithium battery. The supplied voltage is then regulated to 3.3VDC by the on-board power supply circuit. The radio module operates in license-free bands at 915 MHz (902.75 to 927.25 MHz). RFW-201 Nodes are fully compatible with mesh network hardware, protocols and operations. Five radio transmission data rates are available: 9.6 kb/s, 19.2 kb/s, 38.4 kb/s, 76.8 kb/s and 153.6 kb/s. The transmission power of the 915 MHz radio is adjustable from 20 dBm to -20 dBm.
CUG RFW-201, Revision 1 4 RFW-201 User’s Guide 2 Regulatory Notices Warning The Original Equipment Manufacturer (OEM) must ensure that FCC Labeling requirements are met. This includes a clearly visible label on the outside of the OEM enclosure specifying the Eaton’s Cooper Power Systems FCC identifier (FCC ID: P9X-500LG) and IC Number (IC: 6766A-500LG) as well as the FCC Notice below. Warning This device complies with Part 15 of the FCC Rules. 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. Warning Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Warning Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Warning 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 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.
CUG RFW-201, Revision 1 5 RFW-201 User’s Guide Warning The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb. Warning To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operate in conjunction with any other antenna or transmitter.” As such, the radio component of this device is intended only for OEM integrators under the following two conditions: The antenna must be installed such that 20 cm is maintained between the antenna and users. The transmitter module may not be co-located with any other transmitter or antenna. As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (e.g., digital device emissions, PC peripheral requirements). In the event that these conditions cannot be met (for example, co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm may be maintained between the antenna and users (for example access points, routers, wireless ASDL modems, certain laptop configurations, and similar equipment). The final end product must be labeled in a visible area with the following: “Contains FCC ID: P9X-RFW201, IC: 6766A- RFW201”. The radio component is an integral part of the RFW-201 and cannot be removed.
CUG RFW-201, Revision 1 6 RFW-201 User’s Guide Warning Transmitters with Detachable Antennas This device has been designed to operate with the antenna listed below, having a maximum gain of 2.4 dB. Antennas not included in this list or having a gain greater than 2.4 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. Antennas that may be used with this product include:  Linx ¼ Wave through-hole helical – 2.4 dBi 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 permitted for successful communication.
