The RF431 spread-spectrum radio includes a USB port to make it easier to connect to newer computers that do not have RS-232 ports. This 100-mW spread-spectrum radio/modem operates in the 910- to 918-MHz frequency range, which is allocated for Australia/Israel. The RF431 can transmit data to another RF431 radio, an RF411 radio, or CR211(X) datalogger.

The RF431 supports point-to-point and point-to-multipoint communications. Although it typically serves as a base station modem/radio, the RF430 can connect to the datalogger’s RS-232 port to serve as a field modem (requires a null modem cable and a field power cable).

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 and in their frequencies. Refer to the following table for specifics.

RF401 RF430 RF411 RF431 RF416 RF432
Frequency 910 to 918 MHz
US & Canada		 920 to 928 MHz
Australia & Israel		 2.45 to 2.46 GHz
USB & RS-232 Ports
CS I/O &
RS-232 Ports

Benefits and Features

  • Rugged, low-cost transceivers
  • Can be used in the field as a transceiver or in the office as the base station
  • Transmits up to one mile with omnidirectional antenna; up to 10 miles with higher gain directional antennas at ideal conditions
  • Settings stored in non-volatile memory
  • USB port for connecting to a computer; RS-232 port for connecting to a datalogger
  • Frequency-hops over 25 channels avoids interference from other spread spectrum radios
  • 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"
  • Built-in setup menus allow access to advanced functionality
  • Designed for use in PakBus networks
