The RF430 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 used in the US and Canada. The RF430 can transmit data to another RF430 radio, an RF401 radio, or a CR206(X) datalogger.

The RF430 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.

Frequency 910 to 918 MHz
US & Canada		 920 to 928 MHz
Australia & Israel		 2.45 to 2.46 GHz
USB & RS-232 Ports

Benefits and Features

  • USB port for connecting to a computer; RS-232 port for connecting to a datalogger
  • Rugged, low-cost transceivers
  • Transmits up to one mile with omnidirectional antenna; up to 10 miles with higher gain directional antennas at ideal conditions
  • Individual FCC license not required
  • Optional extended temperature testing
  • Settings stored in non-volatile memory
  • Designed for use in PakBus networks
  • Frequency-hops over 25 channels avoids interference from other spread spectrum radios
  • Faster communication due to elimination of some small "link state packets"
  • Ability to have stand-alone 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
