RF412 922 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 dataloggers. 

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

Note to RF411A users: The RF411A is factory upgradeable to an RF412. Contact Campbell Scientific for a Returned Material Authorization (RMA).

Benefits and Features

  • Does not require individual operational license in Australia or New Zealand
  • 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

Compatibility

Communications

The RF412 is over-the-air compatible with other RF412-based products. The RF412 can only communicate wirelessly with other RF412 radios and other Campbell Scientific products that have the "-RF412" option.

The RF412 is not over-the-air compatible with the RF411A. However, the RF411A is factory upgradeable to an RF412. Contact Campbell Scientific for a Returned Material Authorization (RMA).

Notes:
*Use a 18663 null modem cable.
**It is possible to connect a mixed-array datalogger (e.g., CR10, CR10X, CR23X, 21X, CR7) by using an SC932A or SC105 between the datalogger's CS I/O port and the RF412's RS-232 port.
