This 100 mW spread spectrum radio/modem operates in the 910 to 918 MHz frequency range, which is allocated in the US and Canada. In a network of CR206(X) dataloggers, the RF401 can serve as the modem connected to a base datalogger. It can also be used for general purpose wireless data communications.
The RF401-series and RF430-series are spread-spectrum radios that serve as field radios while connected to the datalogger and as base station radios when connected to a computer. They can also serve as a standalone RF routers/repeaters.
These radios can be used for general purpose wireless data communications and support point-to-point and point-to-multipoint datalogger communications.
The different models in these two series differ in their ports used for connecting to computers and dataloggers and in their frequencies. Refer to the following table for specfics.

RF401 Benefits
- Rugged, low-cost transceivers
- Can be used in the field as a transceiver or in the office as the base station
- Individual FCC license not required
- Transmits up to one mile with omni-directional antenna; up to 10 miles with higher gain directional antennas
- Settings stored in non-volatile memory
- Designed for use in PakBus networks
- Frequency-hops over 25 channels
- Optional extended temperature testing
- Faster communication due to elimination of some small "link state packets"
- Ability to have standalone RF router/repeaters (up to 8 repeaters)
- Greater immunity to interference and RF collisions by using RF retries
- Reduced power consumption by the datalogger, as the radios perform "packet address filtering"
- Setup allows different addresses for multiple dataloggers in a point-to-multipoint network
- Built-in setup menus allow access to advanced functionality
