Overview

RF427 905MHz + 920MHz Spread Spectrum Radio for use in Brazil (-40 to +70C) (Ships as 32703, 16675 & 17648)

The RF427 is a high-speed 900 MHz serial radio designed for unlicensed operation in Brazil. The RF427 is a frequency-hopping spread-spectrum radio with a configurable transmit-power output of 5 to 250 mW and user-selectable channel masking for improved RF interference immunity. This power-sipping, yet speedy, radio provides a cost-effective way to network data loggers.

The RF427 is part of the RF407 series of radios that includes:

RF407: North America (FCC & IC), 902 to 928 MHz
RF412: Australia (ACMA RCM), 915 to 928 MHz
RF422: Most of Europe and some of Asia (ETSI), 863 to 873 MHz
RF427: Brazil (ANATEL), 905/920 MHz

Benefits

Does not require individual operational license in Brazil
High-speed serial communication, optimized for PakBus networks
Low power (< 2 mA idle) during periods of inactivity
Supports point-to-point with RF retries and point-to-multipoint operations
Remote diagnostics using PakBus node operations
