The RF416 has a 2.45- to 2.46-GHz frequency range, which is used in many countries worldwide. This 50-mW spread-spectrum radio can transmit data to another RF416 radio, an RF432 radio, a CR216(X) datalogger, or an AVW216 interface.
The RF416 supports point-to-point and point-to-multipoint communications. It can serve as a field modem/radio while connected to the datalogger or as a base station modem/radio while connected to a computer. The radio can also serve as a stand-alone RF router/repeater.Read More
The RF401-series and RF430-series spread-spectrum radios are similar. The models in these two series differ in their ports used for connecting to computers/dataloggers, in their frequencies, and in their transmitting power. Refer to the following table for specifics.

Purchase of this product is not recommended for new networks to be deployed in the European Union (EU) that may require future expansion. This and other RF-compatible products will not be available for sale in Europe after 01 Jan 2015 due to changes in EU legislation.
The RF416 reduces susceptibility to RF interference from other spread spectrum devices by providing user-selectable frequency hopping patterns. Spread spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This process allows communications to be more immune to noise and interference from RF sources such as pagers and cellular phones.

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 datalogger 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).
*Although the CR9000 and CR9000X are compatible, RF416 radios do not support their fastest communication rates, and are therefore not practical for many CR9000(X) applications.
**Use a 18663 null modem cable.
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 datalogger as long as two conditions are met:
These radios ship with an SC12 serial cable and a 10873 RS-232 cable.
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.
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.
