1 About the RFN-500LG

The RFN-500LG is a radio communications device designed for use in L+G Focus
meters. It can also be used in Eaton’s Cooper Power Systems Gateways and Relay
Nodes. The RFN-500LG provides a 915 MHz radio interface to an RF mesh network.

The RFN-500LG operates from a power source of 120 VAC to 277 VAC, received from
the host device. It may also be powered from a 12VDC power source. The supplied
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-500LG 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 30 dBm to -20 dBm.
