RF412
RF412
Orderable922 MHz Spread-Spectrum Radio
Overview
The RF412 is a high-speed 900 MHz serial radio designed for unlicensed operation in several countries, including Australia and New Zealand. The RF412 is a 915 to 928 MHz frequency-hopping spread-spectrum radio with a configurable transmit-power output of 5 to 250 mW and software-selectable channel masking for improved RF interference immunity. This power-sipping, yet speedy, radio provides a cost-effective way to network data loggers.
The RF412 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 870 MHz
- RF427: Brazil (ANATEL), 905/920 MHz
Note to RF411A users: The RF411A is factory upgradeable to an RF412. Contact Campbell Scientific for a Returned Material Authorization (RMA).
