RF401

Communications

Internal Radio of CR206(X) Dataloggers

The RF401 spread spectrum radio can communicate with the internal spread spectrum radio of our CR206(X) dataloggers. Certain RF401 settings must match the CR206(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).

Other Spread Spectrum Radios

The RF401 radios can be used in networks containing RF430 and RF400 radios. RF401 radios in networks that include RF400 radios must use the Transparent protocol setting. Also, If RF400 and RF401 radios will be in the same RF proximity, do not use for the RF400 Net Address: 28, 44, 52, 56, or 60. RF400 radios with Net Addresses of 28, 44, 52, and 56 interfere with RF401 radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF400 Net Address of 60 interferes with all RF401 Net Addresses.

Campbell Scientific does not recommend using the RF401 in networks containing FGR-115 or RF450 radios.

Transparent and PakBus Protocols

Do not mix RF401 radios set to the Transparent protocol with RF401 or RF430 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).

Datalogger Considerations

Compatible Retired Dataloggers

Notes:
*Although the CR9000 and CR9000X are compatible, the RF401 radios do not support their fastest communication rates, and are therefore not practical for many CR9000(X) applications.

Enclosure Considerations

A desiccated, non-condensing environment is required. The 14162 Mounting Kit includes hardware for securing the RF401 to an enclosure backplate (see Ordering Info).
