The RF415 was a 50 mW spread spectrum radio/modem for point-to-point and point-to-multipoint data logger communications. It could serve as a field radio/modem connected to a data logger or as a base station radio/modem connected to a computer. The RF415 had an operating frequency range of 2.45 to 2.46 GHz, which is used in many countries world-wide.



Operating Frequency 2.450 to 2.460 MHz
Type Frequency Hopping Spread Spectrum (FHSS) Transceiver
I/O Data Rate 9600 bps
Channel Capacity 65,000 Network Identifiers share 25 hop channels.
Frequency Hopping Patterns Six different selectable patterns
Frequency Control Direct FM
Receiver Sensitivity -104 dBm at 10-4 bit error rate (Campbell Scientific protocols will issue retries wherever a bit error occurs.)
Interference Rejection 70 dB at pager and cellular phone frequencies
Transmitter Power Output 60 mW (nominal)
Antenna Connector Reverse polarity SMA
Operating Temperature Range -25° to +50°C
Power 9 to 16 Vdc
LEDs Power on, TX, RX, diagnostics
CS I/O Connector 9-pin “D” male for all needed communications lines. Newer loggers provide power to the radio on this connector. Older loggers may require optional power cable pn 14291.
RS-232 Connector 9-pin “D” female (for TX, RX, CTS, ground RS-232 levels)
Power Connector Barrel connector, center positive 12 V for use in base station configuration or with older data loggers. Newer loggers provide power to the radio on the CS I/O connector.
  • Allow an additional 3 in. (7.5 cm) along the longest axis for external cable connection.
  • 11.4 x 7.0 x 2.9 cm (4.9 x 2.8 x 1.2 in.)
  • 12.7 x 7.0 x 2.8 cm (5.0 x 2.8 x 1.1 in.) with mounts
Weight 227 g (8 oz)

Additional Compatibility Information


The RF415 can transmit data to another RF415 radio or a CR215 datalogger. The RF415 may also be used in a network with RF416 radios and/or CR216(X) dataloggers if all of the RF416 radios and CR216(X) dataloggers are set to the transparent mode.

Enclosure Considerations

A desiccated, non-condensing environment is required. The 14162 Mounting Kit includes hardware for securing the RF415 to an enclosure backplate (see Ordering Info).
