The RF416 spread-spectrum radio can be used for general purpose wireless data communication and supports point-to-point and point-to-multipoint data logger communication. It can serve as a field modem/radio while connected to the data logger or as a base station modem/radio when connected to a computer.
The RF416 has a frequency range of 2.450 to 2.482 GHz, which is used in many countries worldwide. It can communicate with other RF416 radios, and RF432 radios, as well as the internal radio in CR216(X) dataloggers and AVW216 interfaces.
Note: The operating frequency band of this radio modem may be shared with other non-licensed services such as cordless telephones and with licensed services including emergency broadcast and air-traffic control.
Read MoreSpread-spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This allows the communications to be highly immune to noise and interference from RF sources such as pagers, cellular phones, and multipath. The RF416 reduces susceptibility to RF interference from other spread-spectrum devices by providing user-selectable frequency-hopping patterns.
Spread spectrum radios, like all FCC Part 15 devices, are not allowed to cause harmful interference to licensed radio communications and must accept any interference that they receive. Most Campbell Scientific users operate in open or remote locations where interference is unlikely. If there is a problem, interference can be reduced using methods such as moving the device, reorienting or using a different type of antenna, or adding RF shielding.
At the base station, the RF416 is powered using the 15966 wall charger. At the field site, the RF416 is typically powered by the data logger through the CS I/O port. The #14291 Field Cable is required at the field site for the following situations:
Campbell Scientific offers a variety of antennas for this radio. The 16005 is an omnidirectional 1/2-wave, 0 dBd, whip antenna that connects directly to the radio (no cable required) and can transmit short distances (up to 1 mile). The 17480 dipole antenna includes adhesive for window or wall mounting and a cable for connecting to the radio.
Our higher gain 30411 omnidirectional and 16755 Yagi antennas require a cable to connect them to the radio. The 31314 surge protector is available for radios susceptible to lightning or electrostatic buildup or when the cable length needs to be longer than 3 m (10 ft), as measured between the transceiver and the antenna.

The RF416 spread spectrum radio can communicate with the internal spread spectrum radio of our CR216(X) dataloggers. Certain RF416 settings must match the CR216(X) settings for communications between the radio and data logger to be successful. The factory default settings of these devices may not match; therefore, they may need to be reconfigured before communications can take place. For more information, refer to the Quick Reference Guide for Setting Up RF401-to-CR206 Communication application note (see Documents on the right).
RF416 radios can be used in networks containing RF432 and RF415 radios. When RF416 radios are used in networks that include RF415 radios, the Protocol must be set to Transparent. Also, If RF415 and RF416 radios will be in the same RF proximity, do not use 28, 44, 52, 56, or 60 for the RF415 Net Address. RF415 radios with Net Addresses of 28, 44, 52, and 56 interfere with RF416 radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF415 Net Address of 60 interferes with all RF416 Net Addresses.
The RF416's 2.4 GHz radio is also a good fit for parallel operation in RF450, 900 MHz networks due to the frequency difference (i.e., 2400 MHz versus 900 MHz).
Campbell Scientific does not recommend using the RF416 in networks containing FGR-115 radios.
Do not mix RF416 radios set to the Transparent protocol with RF416 or RF432 radios set to either of the PakBus protocols, since this will produce RF traffic without any RF communications. However radios with the PakBus Aware and PakBus Node settings can coexist in the same network (i.e., some radios set to PakBus Aware and some radios set to PakBus Node).
A desiccated, non-condensing environment is required. The 14162 Mounting Kit includes hardware for securing the RF416 to an enclosure backplate (see Ordering Info).

Yes. The BMP5 Direct SDK can communicate with the data logger as long as two conditions are met:
The RF416 is a 50 mW, 2.45 to 2.46 GHz radio that requires true line of sight. In a dry environment, with absolutely no physical obstruction to impair the line-of-sight path, and with the proper and elevated antennas, the expected range is approximately 5 miles for the RF416.
These radios ship with an SC12 serial cable and a 10873 RS-232 cable.
Antenna selection depends on multiple criteria:
To help with antenna selection and site placement, consider renting and using a demo kit to test the pathway quality. Campbell Scientific offers a 900 MHz demo kit for the RF401, RF430, CR206X, and AVW206, as well as a demo kit for the RF450. Contact Campbell Scientific for assistance.
