1 About the RFN-430SL
The RFN-430SL is a radio communications device designed for use in Itron Sentinel
meters. It can also be used in Cooper Power Systems Gateways and Relay Nodes. The
RFN-430SL provides a 915 MHz radio interface to an RF mesh network.
The RFN-430SL operates from a power source of 120 VAC to 480VAC, received from the
host device. This voltage is then regulated to 5.0 VDC and 3.3VDC by the on-board
power supply circuit. The radio modules operate in license-free bands at 915 MHz
(902.75 to 927.25 MHz). RFN-430SL Nodes are fully compatible with mesh network
hardware, protocols and operations. Three radio transmission data rates are available:
38.4 kb/s, 76.8 kb/s and153.6 kb/s. The transmission power of the 915 MHz radio is
adjustable from 30 dBm to -20 dBm.
