RF407 900 MHz Spread-Spectrum Radio


The RF407 is a high-speed 900 MHz serial radio designed for unlicensed operation in several countries, including the United States and Canada. The RF407 is a 902 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 RF407 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 RF401A users: The RF401A is factory upgradeable to an RF407. Contact Campbell Scientific for a Returned Material Authorization (RMA).

Benefits and Features

  • Does not require individual operational license in the United States or Canada
  • 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

The RF407 is over-the-air compatible with other RF407-based products. The RF407 can only communicate wirelessly with other RF407 radios and other Campbell Scientific products that have the "-RF407" option.

The RF407 is not over-the-air compatible with the RF401A. However, the RF401A is factory upgradeable to an RF407. Contact Campbell Scientific for a Returned Material Authorization (RMA).

Datalogger Considerations

Mixed-array dataloggers **

*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 RF407's RS-232 port.
